Welfare Workers were administered five psychological
tests after having been rated by their supervisors as to
overall suitability. Four hypotheses were tested concerned
respectively with (1) the comparability of welfare workers'
test scores with the scores of other "helping-professions",
(2) the score differences between High-rated and Low-rated
groups, (3) the significance of the multiple correlation
calculated between predictor variables (scores) and the
rating criterion, and (4) the fakability of the three non-
cognitive tests. The data were analyzed separately for the
two sexes.
Subjects consisted of the population of welfare
workers employed with a large public welfare department. The
"Major group" of 69 males and 76 females pertained to hypo¬
theses (1), (2), and (3) while a smaller group of 20 males
and 16 females ("Simulation group") were utilized in testing
hypothesis (4). The tests used were: Valentine's Reasoning
Test, Wonderlic Personnel Test, Maudsley Personality Inventory,
California Psychological Inventory, and Strong Vocational
Interest Blank.
All four hypotheses were supported for both male and

feinale samples except hypothesis (2) for the female sample,
for which the number of dimensions significantly discrimin¬
ating the High-rated from the Low-rated groups was slightly
less than the required fifty percent.
The intellectual, personality, and interest character¬
istics of the typical welfare worker, as well as of the high¬
rated and the low-rated workers, were described. Considera¬
tion of those variaoles most discriminating the high- from
low-rated groups, and of those found to contribute most
independently to the multiple regression equations, provided
further definition to these groups.
In spite of the apparent fakability of the non-
cognitive tests, both quantitative and "pattern” differences
were noted between the High-rated and the Simulation groups'
scores. Possible directions for further related research on
this and the other findings were suggested.

ACKNOWLEDGEMiiNTS
Upon the completion of this study I would like to
express ray gratitude to my supervisor, Miss. L. Wilson,
for her guidance and constructive criticism, as well as
to the other members of my thesis committee; to the sub¬
jects of the study, for finding the time to be away from
demanding caseloads; to the Department of Public Welfare

INTRODUCTION
U GENERAL STATEMENT OF THE PROBLEM
The expanding welfare services being requested and
supplied throughout much of the world today coupled with an
annual graduation of qualified social workers that is below
capacity (Kendall, 1957), has inevitably resulted in a seri¬
ous shortage of professional staff (Albee and Dickey, 1957;
Grygier, 1963; Oettinger, 1963). This is further aggravated
by the administrative morass into which the more casework-
oriented professional feels he or she is sinking (Leigh,
1963) and by the high attrition rate of this female-dominated
profession (Watson, 1963a). Concern over the effective de¬
ployment of welfare personnel thus ranks among the most
urgent priorities in the social welfare field. Opinion in
Canada is becoming more widespread that "we must tackle
seriously the idea of having more of the workload carried by
personnel with less than professional qualifications" (Fisher,
1963). In areas without a school of social work there is
little actual choice in the matter. Oettinger (1963) states
that half of U.S. counties have no full-time trained welfare

staff while in the other half the percentage of workers with
some training actually decreased from 517o in 1950 to 43% in
1960. In England, the Younghusband report recommended a new
grade of "welfare assistant" to help alleviate the similar
situation there (Nicholson, 1959). There is no reason to
believe the situation is brighter in other countries. Hence
unqualified welfare workers, to be distinguished from grad¬
uate social workers, form the bulk of welfare personnel and
their numbers, of necessity, appear to be increasing.
This situation has resulted in increasing attention
being focused upon the classification and differentiation of
positions and tasks for the non-professional worker which
would enable the development of more consistent in-service
training programs and undergraduate social work education
(Manson, 1963). Stress seems to be laid upon the most effec¬
tive integration of task with skill or training. However, as
pointed out by Gripton (1960), in-service training by itself
apparently does not ensure a higher standard of service or
predictable improvement in welfare worker competence.
Presumably there is an optimal range of intellect for the
responsibilities involved, pre-screening in terms of which
should improve the position. However, the application of such

intelligence would prove even more fruitful according to
Grygier (195b), if, in selection, cognizance is also taken of
the personality characteristics most suited to the various
interpersonal occupations; characteristics not elicited
through training and often at a premium. The assessment of
interests was thought by McCornack and Kidneigh (1954) to be
of comparable importance in this regard.
Opinion held by administrators in these fields regard¬
ing the nature of such requisite qualities is apparently
often intuitive, idiosyncratic, and biased by a priori con¬
victions rooted in certain theories. Thus, in the social
work profession, selection decisions are normally based upon
assessments of applicants' levels of maturity, poise, empathy,
discretion, etc. gained through "the interview technique"
with heavy reliance on the "dynamic interrelationships" de¬
veloped therein to provide clues to the above (Bishop, 1948;
Berentgarten, 1949; Towle, 1952). The construct "relation¬
ship" as so frequently used in social work was concluded by
Shively (1961) to be cloaked in ambiguity and its meaning to
possess little or no reliability. An immersion in psychoan¬
alytic theory appears to have resulted in a certain aversion
to objective assessment methods in this profession. Sanua

(19o3) points out that although other professional schools
(law, medicine, engineering, etc.) utilize psychological
tests to aid selection decisions, this has not been the case
with social work.
To the extent that hiring decisions in welfare agencies
are influenced by professionally-schooled administrators a
similar orientation would likely also prevail in the selection
of welfare workers. However, according to Newman (1961) there
has been "little effort to define objectively the personal
qualifications needed for social service" in any case, whether
in psychoanalytic strongholds or otherwise. In view of the
evidence against the efficacy of interview alone (Viteles,
1945; Guildford and Lacey, 1947; Kelly and Fiske, 1950; Zubin,
1957; Holt and Luborsky, 1958; Sydiaha, 1962) some alteration
in this position would appear justified. The recent opinion
of a prominent social welfare researcher that "the development
of a selection battery (of tests) would be useful for both
non-professional personnel and in candidate selection for
graduate schools of social work" (Watson, 1963b) may represent
a new view point in the profession. The utility of psycho¬
logical tests in social work generally is further emphasized
by Grygier (1963) who feels the use of more objective tools

to assess both client and worker characteristics would lead
to more productive casework.
The problem with which the present study was therefore
concerned was that of identifying, with the use of several
group paper and pencil tests, some of the psychological
variables (purportedly measured by such tests) which most
characterize, respectively, a male and a female sample of
public welfare workers. This is dealt with under Part A.
The variables which best discriminate those workers given high
ratings from those given low ratings on a suitability criter¬
ion were also sought and are dealt with in Part B. The type
of variables identified by psychological tests were expected
to afford, at least tentatively, more explicit bases for
inter-subjective agreement and common frames of reference
than more intuitive approaches when, for whatever reason, the
attributes of this category of apparently socially adequate
individual (who outnumber graduate social workers) are of
concern. (e.g. in vocational counselling).
The possible application of information as found in
Parts A and B for selection purposes requires that such tests
possess adequate validity in terms of relevant external
criteria and are insensitive to purposeful distortion. An

initial step (only) with respect to the former point was
undertaken also in the present study in a multiple regression
analysis of the test variables against the rating criterion
(Part C). Studies estimating the fakability of personality
and interest inventories, whether developed on rational,
empirical, or forced-choice principles, are legion (see Chpt.
II). However, as Dunnette et al (1958) state, in reference
to a typical inventory, ”the C.P.I., as an aid in the selec¬
tion of applicants, will be enhanced with the continued
accumulation of information on the effects of possible faking.”
The fakability of the non-cognitive tests used in the present
study, in terms of the particular criterion herein concerned,
was therefore also investigated, in Part D.
Findings throughout this study, although hopefully
heuristic, should be considered tentative and will require
refinement and cross-validation before conclusive statements
of predictive validity regarding welfare workers should be
made or generalized.
2. STATEMENT OF HYPOTHESES
The following refer equally and separately to the male
and the female samples. With respect to Part A, a descriptive
analysis of welfare workers, it was hypothesized that:

'welfare workers would achieve scores on the tests given com¬
parable to other helping-professions but different, in many
respects, from those of such as salesmen, scientists, and the
socially inadequate, where such norms are available'. A more
explicit hypothesis was not thought justified for this
exploratory enquiry.
With respect to Part B, a discrimination of workers in
terms of suitability, it was hypothesized that: 'the differ¬
ence between test score means of those workers in the High¬
rated group and the Low-rated group would be significant on
the majority of dimensions measured'.
With respect to Part C, the multiple regression analy¬
sis, it was hypothesized that: 'the multiple correlation
between the ultimately selected predictor variables, as
weighted in the regression equation, and the rating criterion
would be significantly greater than zero'.
With respect to Part D, the fakability analysis, it
was hypothesized that: 'the majority of Simulation group
mean scores on those variables shown to discriminate the
High/Low groups or included in the regression equation would
either not differ significantly from, or would fall beyond
(in the diredion of suitability) the comparable High-rated

All above-mentioned groups are defined in Chapter III.
The choice of ’’majority" for the hypotheses of Parts B and D,
although admittedly somewhat arbitrary, allowed some basis
for generalization of whatever conclusions were reached
regarding, respectively, the relevance of the tests chosen,
and the fakability of their more discriminating variables, in
the context of this study.

CHAPTER II
REVIEW OF THE LITERATURE
The present investigation is not particularly concerned
with the more esoteric problems inherent in the separate
topics of criterion analysis, rating procedures, personality
theory, inventory validity, regression analysis, faking,
personnel selection, social work, vocational interests, intel¬
ligence, etc. per se. Each of these could be probed in depth
in conjunction with studies explicitly delimited to one such
problem. The following review will therefore be consistent
with the exploratory nature and format of the present study,
incorporating certain marginal topics only as they pertain to
the identification of welfare worker characteristics. For
convenience however this discussion is divided into sections
dealing with studies on "helping-professions”, rating criteria,
and inventory fakability.
STUDIES RELATING TO THE "HELPING-PROFESSIONS"
The majority of studies concerned with identifying
attributes and improving selection methods of potentially
suitable trainees in these fields have dealt with graduate
students entering clinical psychology, psychiatry, public

health, and social work. To this writer's knowledge no psy¬
chometric studies have been reported involving untrained
welfare workers, in spite of their increasing numbers and im¬
portance (see Introduction). Sanua (1963) remarks that
"while lengthy investigations have been conducted with top
level helping-professions, very little work has been published
on the less prestigeful "helping-vocations' or sub-profes¬
sional personnel". Of the latter there have been some studies
on psychiatric aides, psychiatric nurses, and military social
work aides. These and some of the above studies provide the
more meaningful data for comparison with the present study.
Cliff, Newman, and Howell (1959) reviewed several
studies seeking to identify successful psychiatric aide quali¬
ties and concluded that no predictive personality variables
had yet been isolated; that ability tests were the only
promising tool. One typical study (Cuadra and Reed, 1957)
found the C.P.I. did not differentiate the better from less
suitable aidesand concluded that the criteria were either
unrelated to personality variables or were over-shadowed by
intellectual and experiential factors. A Ph.D study by Sidney
(1957) similarly found no scales on either the Guildford-
Zimraerman or Kuder to be predictive of psychiatric aide

proficiency.
Rosenburg et al (1962) found the average score on three
intelligence tests more predictive of military social work aide
course success than all C.P.I. scales except Self acceptance
and Achievement by independence. These latter did however
contribute something to a multiple regression equation while
scales of the p$ychiatrically-oriented MMPI did not. Marin
(1953), in a Ph.D. dissertation, reported no scales on the
Bernreuter predicted graduate social work success although a
correlation of .38 was obtained between grades and a combined
score (social-emotional scales) on the Bell Adjustment Inven¬
tory. These two studies however did not utilize, as did those
with psychiatric aides, practical proficiency as criterion.
It would appear that in these interpersonal occupations acade¬
mic success can, at times, be predicted by personality variables
but actual performance, in which "the whole person” would be
expected to be even more involved, is not.
This situation is further complicated by the findings
of Goldstein (1960) and Sanua (1963) who gave graduate social
work students an ability test (Miller's Analogy) to predict
grades. Correlations were not significant however and for
males and females were of different sign.. Holt and Luborsky

(1958), studying post M.D. student selection for psycliiatry
training, found experts' opinion on the relationship between
academic performance in medical school and later psychotherapy
ability ranged from "considerable" to "none". Kelly and Fiske
(1950) found the Miller correlated .47 with clinical psychol¬
ogy student grades but only .02 with therapy skills, the best
correlation with the latter being a measure of extroversion.
These studies have relevance because of the comparability of
social casework and psychotherapy.
Sanua (1963) is of the opinion that projective tech¬
niques, by providing a measure of unconscious motivation,
would improve prediction of suitability in personal contact
occupations. Two Rorschach studies (Pietrowski, 1946;
Frankie, 1951) found a significantly greater number of Move¬
ment responses given by the more proficient social work
students than those of less ability. However the effect of
intellectual differences was evidently not considered.
Grygier (1956), who found a verbal I.Q, test more predictive
of psychiatric nursing grades than psychoanalytically-based
measures still feels such assessments are superior to social
behaviour questionnaire approaches for such prediction.
Projective and psychoanalytic methods allegedly also

point out certain pathological factors, however inventory and
life history data may be similarly oriented. Lewis (1947)
found high Depression and Hysteria scores but low Hypochon¬
driasis, Psychasthenia, and Schizophrenia scores for social
workers on the MMPI. Sanua (1936) and Roe (to be published)
found social workers above average in neuroticism on the MMPI
and 16 PF tests respectively, especially the male workers.
Roe attributed her findings to a high incidence of difficult
early home environments in those who select social work,
hypothesizing a search for more satisfying relationships.
Berengarten (1940) reported similar findings with sibling
rivalry, isolation, dependency, and parental conflicts char¬
acterizing their early environments. Nachman (1957) found
social workers typically to have had dominant mother-figures
and weak or no father-figures with a consequent feminine
orientation to matters of discipline and empathy, in compari¬
son to lawyers and dentists. There was also some deprivation
in infancy. Tibbie (1959) asked trainee social workers to
express their main anxieties regarding their new roles and
found "they were particularly concerned with their adequacy
in human relations in unfamiliar social contexts”.

social work students with students in other professional
schools. Their major finding was that they were more liberal
and less dogmatic than those in other schools, regarding
political, social, family, and economic matters. They con¬
cluded this attitude allowed non-judgemental responses to
clients, meeting dependency without control, and an accept¬
ance of new problems. Examining biographical data they con¬
cluded neither age nor experience were important factors in
social work student proficiency but noted that such students
chose their vocation later in life than those in other pro¬
fessions .
Barthol and Kirk (1956), using the Concept Mastery,
MMPI, and Strong tests, attempted to improve selection of
graduate students for a public health diploma course. They
found difficulty "in the determination of selection scores
and profiles", possibly due in part to their failure to use
a multiple regression technique. They found all the tests
would screen out the poorer prospects but simultaneously eli¬
minated too many of the good students. The Strong social
services scales (Group V) were scored highly by all applicants,
but were not discriminating. Only the verbal-linguistic
scales (Group X) were positively related to' success. None

were discriminating for the females although the Social
Worker, Psychologist, and Lawyer scales approached signifi-
canc e.
Other interest studies by Lewis (1947), McCornack and
Kidneigh (1954), and Gravitz and Mintz (1953) found social
work students liked contact with people and verbal activities
while disliking the manual trades, physical sciences, isola¬
tion, and the selling fields. On both the Strong and the
Kuder the social services category was, not surprisingly, the
most highly scored. These studies did not hovjever report
correlations with or predictability of criteria. Kelly and
Fiske (1950) reported some significant prediction by Group I
(creative-scientific) Strong scales with clinical psychology
grades (.26) and clinical competence (.21). However Holt and
Luborsky (1958) found the Strong gave largely negative result
for prediction of suitability in psychiatry, although it is a
closely allied helping-profession. Abeles (1958) however
found interest differences to be more discriminating between
trainee counselors given high and low global ratings by
supervisors than ability or adjustment measures.
Findings in the above studies, even those with social
workers, do not necessarily generalize to non-professional

welfare workers. Motivations may be different and the wider
educational range of the latter could result in greater pro¬
ficiency discrimination by various assessment procedures.
2. STUDIES RELATING TO RATING CRITERIA
Conflicting opinion exists regarding the reliability
and validity of all rating procedures, whether peer, super¬
visory, or self; structured or unstructured; descriptive or
numerical. Krause (1960) concluded "one type of rating is
as good as another", but felt the concept was necessary and
nee,ding further exploratory research.
Subjective evaluation of overall performance may,
state Prien and Liske (1962), be the only criterion available
where that predicted is of a complex nature. Guion (1961)
found sub-criterion measures (job-dimensions), even if known,
to be often unrelated to total performance. Thus Topetzes
(1956), who correlated occupational therapy training success
with ratings on thirty apparently relevant traits, found uni¬
formly low correlations. Jay and Copes (1957) found "broad
category (overall) ratings" the least influenced by the sen¬
iority of those rated. Sub-category ambiguity errors and
summated halo effects are minimized thereby as well.
The validity of ratings is generally expected to

increase with more raters per ratee to the extent that inter¬
rater agreement is high. However, Buckner (1959) found
higher predictive validity for a complex criterion occurred
when inter-rater agreement was low than when it was high*
He attributed this to different raters being expert on, or
perceiving, different facets of the total performance variance.
This same principle is implicit where different raters rate
different sections of a total sample. Distefano and Bass
(1959) obtained a significant rank correlation between law
students' admission test scores and numerical (1 to 5) ratings
by court judges of their overall legal ability five years
after graduation; each judge (in a different county) rating
only an isolated sub-group of the total sample on which the
correlation was based. Windle and Dingman (1960) feel such
unique frames of reference allow greater validity where the
criterion is complex than when it is uni-dimensional.
3. STUDIES RELATING TO INVENTORY FAIC/\BILITY
This topic has been studied at least as early as 1932
(Steinmetz) following which it has been given continual atten¬
tion, e.g. Kelly et al (1935), Borden (1943), Paterson (1946),
Gough (1947), Longstaff (1948), Wesraan (1952), Garry (1953),
Heron (1956), Rusmore (1956), Bass (1957), Sorenson (1953),

Krug (1958), Borislow (1953), Mayo and Guttnian (1959),
Dickens (1960), Riniland (1962) Dunnette (1962), Kirchner
(1962). The general conclusions have been that when instruc¬
ted to simulate various roles testees can fake interest and
personality inventories.
Certain studies are of relevance to the present in¬
vestigation. The empirically developed C.P.I. was reported
fakable by Dunnette et al (1953) and by Jackson and Messick
(1953) who claimed a significant proportion of its total var¬
iance was accounted for by easily faked social desirability
responses. However Dickens (1960) found it less fakable than
the E.P.P.I., a forced-choice inventory equating binary items
in terms of social desirability. The type of inventory which
can adequately control for social desirability is evidently
as yet unperfected (Borislow, 1958; Maher, 1959; Messick,
1960) although Norman (1961, 1962) appears to have made some
progress in this regard.
Eysenck (1959) admits the N scale on his M.P.I. can be
purposely distorted although felt the E scale was moreresist-
ant. Taylor’s M.A.S. was shown by Mills and Hannum (1959) to
be similarly transparent. Longstaff (1945), Paterson (1946),
and Garry (1953) reported the Strong to be fakable, as did
Gehman (1957) who found Engineers could simulate various roles,

particularly the social services group. The utility of such
tests are therefore generally felt to be restricted to situa¬
tions in which the testee has a desire to know or communicate
his real, typical characteristics.
A further consideration however should be made regard¬
ing test fakability: although fakable, will they actually be
faked in situations other than those providing instructions
to fake? Green (1951), Heron (1956), Gordon (1956), Bass
(1957), Sorenson and Sheldon (1953), Kirchner (1962), Rimland
(1962) and Dunnette (1962) investigated this question and
found generally that most scores did not increase significantly
in the desirable direction under realistic "vested-interest"
conditions. Sociability or extroversion scales were particu¬
larly unmodified while emotional adjustment measures showed
some increase. Sorenson and Sheldon (1958) concluded faking
to be more unlikely when the particular dimensions measured
are poorly realized by the subjects. The type of person
(sample) concerned is important. Kirchner (1962) found that
applicants for sales positions faked more than those applying
to be technical representatives, yet even sales applicants
were found by Dunnette (1962) to fake much less (only one in
seven) than employees instructed to fake good on the same test.

CHAPTER III
METHOD
l_. THE S/\MPLE
The total welfare worker staff employed with a large,
province-wide public welfare agency was divided into two un¬
equal groups. The major group, of 160 subjects, consisted of
workers from larger regional offices having staffs of 4 or
more workers, while a smaller group, of 40 subjects, repre¬
sented workers from smaller offices. This latter group, for
whom ratings would likely have been the least reliable, was
restricted to that phase of the project concerned with the
attempted simulation of the non-cognitive tests. Moreover,
Riraland (1962) and Palermo (1961) found simulation and actual
scores were reciprocally modified when both instructional sets
were assumed by the same group, with the order significant.
Separate groups were therefore used in the present study.
In order to maintain subject anonymity biographical
data of the major sample was obtained on four variables in
dichotomous form only: Sex (male or female); Age (over or
under 30 years); Education (degree/diploma or not); and Length
of Service (over or under 1 year). Percentages falling in the

2. THE CRITERION
A memorandum outlining the general nature of the re¬
search was sent to office and unit supervisors in the larger
offices requesting they rate each of their workers on a single
criterion of ’’overall welfare worker suitability and profi¬
ciency”. A 10 point numerical rating scale was used which
ranged between the numbers 70 to 79 to take advantage of our
cultural set regarding grading or being graded out of 100.
This particular decile range would, it was hoped, allow

discrimination with little constraint due to "conscience",
thus minimizing generosity errors, as compared with scales
which possess a more explicit raid-point and consequent value-
ladened lower and upper halves. By informing raters that
"there are satisfactory workers elsewhere who would be rated
in the 50's and 60's but we are assuming we have none here,"
it was expected that ratings in the low 70's would not be
avoided to the extent they would be were such ratings re¬
garded as or identified with negative or failure values.
(For full instructions to raters see Appendix 1). No attempt
was made to define suitability or proficiency for the super¬
visors. Rating distributions for males and females ultimately
tested are shown in Figs. 1 and 2 in Results.
To allow anonymity supervisors were instructed to
choose, from a range of numbers arbitrarily assigned each
office or unit, a code number for each worker beside which
the appropriate rating was to be recorded. The particular
tests to be subsequently administered were purposely not
identified at this point in order to minimize criterion con¬
tamination due to subjective anticipation, by raters, of
predictor-variables.

3. THE TESTS.
Cognitive:
(a) Reasoning Tests for Higher Levels of Intelligence
(Valentine, 1954).
This test is said to provide an assessment of "general
reasoning ability" at a level suitable for use in the selec¬
tion of entrants to such as British universities and teacher's
training colleges. Its two parts provide tests of induction
and deduction respectively with a liberal total time limit
(55 minutes). Although there are at present no North Ameri¬
can norms the test's reviewer (Dale, 1959) recommends its
experimental use therein for "cross-fertilization" purposes.
Its author claims that as its purpose is "to provide.... a
basis on which to select entrants" all that will be needed is
"comparative estimates among applicants". However some rele¬
vance attaches to comparisons with norms provided on the
teacher-training groups who possess both an educational level
and an interest in people comparable with welfare workers.
It was expected that this test would provide a discriminating
measure of the type of reasoning ability required in helping
to solve those interpersonal and social-living problems, often
involving many variables, with which welfare work is concerned

(Wassernian and Gitlin, 1963). Three scores, induction, de¬
duction, and total are obtained.
(b) V\/onderlic Personnel Test (Wonderlic, 1945)
This short (12 rainute) test consists of 50 items cov¬
ering a wide variety of intelligence dimensions (numerical,
verbal, spatial, etc.) having wide application in personnel
research (Buros, 1953, 1959). Its inclusion in the present
study was expected to allow efficient coverage of such addi¬
tional domains as may be pertinent but not measured by (a)
above. It provides a total score only. Considerable norma¬
tive data is available.
Personality:
(a) The Maudsley Personality Inventory (Eysenck,
1959) is a short (48 item) yes? no inventory purporting to
measure two basic personality dimensions, neuroticisra (N) and
extroversion (E). It was constructed empirically by a method
of criterion factor analysis providing measures said to be
relatively pure and independent. This test was included in
the event these factors might contribute efficiently to the
prediction of the criterion by accounting for non-overlapping
portions of its variance. Norms are available for both
English and American normal groups as well as certain psychi¬
atric groups. A third score, E minus N, was also obtained

(b) California F'sychological Inventory (Gough, 1957)
consists of 430 True/False items providing measures on 18
scales considered by the author to be ’’characteristics im¬
portant for social living and social interaction”. It was
constructed on empirical rather than rational bases utilizing
criterion groups thought to characterize the dimensions meas¬
ured. Interpretation is meant to stress degrees of normal
functioning rather than the converse. The characteristics
needed in the interpersonal activities of welfare workers,
often under frustrating pressures (Schmidt, 1963), would seem
to be suited to measurement by this instrument. Both male
and female norms are available for a number of academic and
occupational categories including graduate social work stu¬
dents and certain socially inadequate groups.
Interests:
The Strong Vocational Interest Blanks for men and women
(Strong, 1959) each contain 400 items to which one responds in

terms of liking, disliking, or indifference. They were de¬
veloped by the empirical technique to provide measures of the
degree to which one's interests compare with those of various
occupational groups. The 45 specific occupations listed on
the men's form are divided into 11 more general occupational
Groups while the 29 occupations on the women's form can be
divided into 14 such Groups (see appendix). Each form has,
in addition, a Masculinity-Femininity scale while the men's
form has three other non-occupational scales: Interest Mat¬
urity, Specialization, and Occupational Level. Those scales
in the Social Services category especially were expected to
prove relevant while those in less verbal-interpersonal cate¬
gories should be somewhat discriminating in the negative
direction. Norms are available for all occupations measured
plus the overall general population.
4. COLLECTION OF THE DATA
(a) Major Group.
Once all ratings were received the five tests were for¬
warded to supervisors with administration instructions for the
workers (see Appendix 2.). As each subject handed in a com¬
pleted paper, on which the name space was to be left blank,
the supervisor wrote in the appropriate code number, privately.
2/
The coding system, ensuring anonymity of subjects to both the
researcher and higher administrative staff with respect to
rating and test data, was thought vital to maximize motivation
to respond with utmost honesty. Sorenson (1956) found a sig¬
nificant decrease in a mean adjustment score for non-signers
compared to signers under actual attitude conditions, the
latter achieving a mean score more comparable to that found
under faking instructions. Biographical information, also
identified with code only, was restricted to the dichotomous
form to maintain anonymity. Eighty-nine percent of the tests
were completed and returned resulting in a final sample size
for this group of N=145. This was composed of 69 males and
76 females. Unreturned tests represent workers who either
left the service, were too busy, or were ill during the per¬
iod of data gathering.
(b) Simulation group.
A similar memorandum outlining the project but not in¬
volving the rating aspect was sent to smaller-office super¬
visors requesting that workers complete, again anonymously,
the three non-cognitive tests, M.P.I., C.P.I., and Strong.
These workers were instructed (see Appendix 3) to complete
each of these tests as they felt a most proficient,

respected, qualified social worker would when applying for a
much desired position in welfare, knowing the results would
be taken into consideration by the employer when deciding
whether or not to hire such an applicant. It was again
thought that anonymity would promote adherence to the ob¬
jective of this aspect of the study. Coding was not required
for this group since results were not to be correlated with
ratings or other data. Completed returns represented ninety
percent of this group providing a sample size N=36. This was
composed of 20 males and 16 females. The same factprs
accounted for unreturned tests as in (a).
5. STATISTICAL ANALYSIS
A separate analysis of the collected data according to
sex was prompted both by the existence for some tests of male
and female forms and by the findings of Carlson and Carlson
(1960) who noted that of the many characteristics on which
research groups can be divided none was more justified on the
available evidence nor more often ignored than the sex dicho¬
tomy. Results based on male populations (which they found
form a majority in personality research) are too frequently
generalized to mixed populations or where a mixed group is
used a separate analysis is only infrequently made. Borgatta

and Stimson (1963) have found it necessary to further empha¬
size this point, advising "extreme caution" in such general¬
izations. Similarly, with respect to interests, McCornack
(1954) found that the revised Social Worker keys on the
Strong were very discriminating between the sexes indicating
their inappropriate use for the opposite sex. The original
single key was similarly inappropriate for unmixed groups.
The following procedures were therefore applied separately
to both male and female samples.
Part A. Psychological Description of Welfare Workers.
The descriptive aspect of the research is restricted
to a visual comparison of means and variations on the many
test variables measured with appropriate available norms.
Obviously specific significance tests could proceed almost
indefinitely involving prohibitive calculations as well as
being of dubious psychological value in this context. Statis¬
tics (means and standard deviations) in this part were ob¬
tained via computer as part of the multiple regression results.
The extent to which the means of the biographical variables
fell above or below the dichotomy mid-points was also deter-
2 mined, as a measure of central tendency, by calculating X.
since these variables presumably also serve to characterize

(this sample of) welfare workers.
Part B. Psychological Discrimination of High-rated from Low¬
rated Welfare Workers.
The identification of the test variables providing sig
nificant discrimination of the high-rated from low-rated
workers was effected by calculating t ratios.
The significance of the difference between the ratios
of the 4 dichotomous biographical variables in the High and
2 Low groups were determined by calculating the appropriate X .
Part C. Multiple Regression Analysis.
(1) In the event one or more of the biographical vari
ables might prove sufficiently predictive of the criterion,
point biserial correlations between these and the latter were
calculated and their significance tested with an appropriate
t test. Variables displaying a significant relationship were
then considered for further analysis via (2) below.
(2) A restriction on the number of variables which
the multiple regression program was able to handle necessi¬
tated the computation first of intercorrelation matrices in¬
cluding all test variables, any biographical variables dis¬
playing a significant relationship to the criterion, and the
criterion. Both male and female matrices were examined in an

attempt to identify the 30 variables in each which apparently
most satisfied the requirement of minimal intercorrelation
amongst themselves but maximal correlations with the criter¬
ion. Those selected were analysed further via (3) below,
(3) A stepwise multiple linear regression program
(Smillie, 1962) was revised by its author to increase the
number of variables handled from 16 to 30. This analysis
provides, among other results, the optimal regression coeffi¬
cients for the most predictive independent variables in the
order of their relative contribution. Thus that variable
which accounts for the greatest portion of the criterion var¬
iance is obtained first with the coefficient which, were no
further variables utilized, would provide the maximum multiple
correlation. As the succeeding variables are added the earl¬
ier coefficients alter value slightly, to maximize the corre¬
lation at that point. Various considerations may determine
when no further variables need be included in the regression
equation. When the standard error of the criterion (provided
in the results) reaches a minimum the increase in predictive
efficiency is considered insignificant (Smillie, 1963), so
this criterion was applied in. the present study.
The multiple correlation coefficient R thus derived

was tested for significance from zero by calculating the
appropriate F value.
(4) Tests to determine possible non-linearity of re¬
lationships between the regression variables and the criter¬
ion were required to justify the assumption that a linear
equation was an adequate fit. The square of the correlation
ratio Eta (i|) was calculated from bifrequency tables and its
2 significance from r tested by calculating the appropriate F
value. Linearity exists to the extent that the least squares
via r and are not significantly different.
The formulae for all statistics used are shown in
Appendix 5.
Part D. Analysis of Simulation Scores.
Tests of significance of the difference between Simula¬
tion group means and High group means were made on those
variables selected for the regression equations. These tests
utilized the same formulae as in Part B, for the same reasons.
Where such Simulation means were found to be not significantly
different from or to fall ’beyond' the High group means, re¬
interpretation of the possible utility of the regression
equation would seem warranted.
Comparisons between Simulation means and High means

were similarly made with respect to those variables which
discriminated the High from Low groups but did not predict
the criterion as efficiently as the regression variables.
An estimate of their fakability was considered of comparabl
interest however and was therefore tested in terms of the
same hypothesis.

medical students to 53.4 for Oxbridge scholarship winners.
The relatively wide standard deviations obtained are similar
to those reported for the above British groups, reflecting
the tests discriminating power. Scores by welfare workers
ranged from 2 (obtained by 3 Ss) to 68 out of a possible 71,
Norms are not available for the two sub-scores which however
could have relevance to Parts B or C of this study.
The mean scores on the Wonderlic were not significantly
different for the two groups. They approximate that generally
achieved by American 4th year undergraduate college popula¬
tions (i.e. males - 30,8; females - 29.1) thus exceeding such
as skilled tradesmen and clerical workers by about 8 to 10
points.
The mean male welfare worker N score on the Maudsley
places this group below both English and American general
mixed-sex population means (19.9 and 20.9). The female wel¬
fare worker N score, although slightly lower than the males,
needs to be considered in light of the fact that women gener¬
ally score about 3 points higher than men (Eysenck, 1959). It
appears that while male welfare workers are slightly less
neurotic than men in general, female workers are, in relation
to their normative group, considerably less so (at least in

Eysenck's sense of the term). Both samples' mean E scores
fell between those of English normals (24.9) and American
students (28.5), these values representing mixed-sex
populations.
The mean C.P.I. scores for male workers fall, for every
scale, above men in general indicating, in Gough's interpre¬
tation, better than average adequacy in social and interper-
sonal functioning. No single scale nor group of scales stand
out although further interpretation is presented in Chapter IV.
The female workers achieve scores generally above the men,
being particularly elevated on the Ai and Fx scales. Thus
besides being slightly more adequate in social behaviour (in
its broadest sense) they are particularly more "independent,
resourceful, and flexible" than women in general. However
they do fall below the male workers on Re, So, Gi, and Ac,
suggesting they are less influenced by too restrictive or
conforming ethical and social forces. Further discussion is
given in Chapter IV.
The major finding on the Strong for male workers is
their above average scores on Group V scales (social services)
and the one very low mean on the Physicist scale. The female
group exceed women in general most noticeably on the Social

Worker, Psychologist, and Occupational Therapist scales while
following below mainly on the Life Insurance Saleswoman, Buyer,
and Librarian scales.
Comparisons of the present findings with those of other
"helping-professions” (see Chapters II and IV) indicate, to
the extent that it is possible to be comprehensive, that the
hypothesis of Part A may be accepted. Specifically, the
Valentine scores are comparable to those of teachers, the
Wonderlic to college populations (no "helping-profession"
norms are provided), the M.P.I. N and £ scores fall beyond
the general population in a direction away from psychiatric
groups (Figure 13), the C.P.I. scores are above normal in
terms of social adequacy and quite comparable to social
workers (Figure 14 and 15), while Group V (social service)
Strong scores and those similar in the female form differen¬
tiate this group from the general public, salesmen and physi¬
cal scientists, being similar to those of social workers
(Figure 16/17).
Welfare workers placed typically in certain categories
of those biographical dichotomies measured, as shown in Table
IV. For the total sample the number of male workers is not
significantly different from the number of females. With

respect to age, male workers average over 30 years while fe¬
males do not. The number of male workers with and without
degrees or diplomas is not significantly different, while
significantly more of the female workers do possess such
qualifications than do not. Finally, it is noted that the
majority of males have more than one year of service while
female workers are fairly evenly divided on this dichotomy.

ratings, although the qualities underlying this criterion
could possibly distribute somewhat normally. To the extent
it was primarily the former, validity may be increased by a
transformation of the ten point scale to the range 1 to 7 by
combining the tails thus equalizing the quantity of low, med¬
ium, and high ratings. It is possible this was assisted also
by the particular rating instructions given. Transformed
rating distributions are shown in Figures 3 and 4. It was not
felt there would be an appreciable loss of information by such
a transformation since reliability is undoubtedly not at a
level requiring finer sensitivity.

With respect to statistical analyses normality of the
variates concerned is not required in the computation or sig¬
nificance testing of Pearson's r or its multiple R derivitive
(Nefzger and Drasgow, 1957), while the central-limiting theorem
provides the basis for the ultimate normality of the High and
Low sub-groups to which t-tests were applied. Such groups of
course represent the same upper and lower percentage of total
subjects whether or not tails are combined. The High group
consisted of those in rating categories 6 and 7 while the Lov/
group consisted of those in categories 1 and 2.

2. TEST VARIABLES AS DISCRIMINATORS
Tatiles V and VII show High and Low group means and t-
test results for all test variables. Of the 70 male sample
variables on which scores were obtained 39 or 55,7% proved
discriminating at the .05 level of significance. This
supports the hypothesis of Part B for this sample. The parti¬
cular tests chosen appear to provide, for the male sample, an
efficient coverage of the dimensions underlying the criterion,
with the discriminating variables being represented relatively
equally on all tests. The more discriminating are however
found primarily in the cognitive and interest tests, with the
total and deduction Valentine scores, the SW, OL, and PA
scales proving the most discriminative. The rank order of the
significantly discriminating male variables {test and bio¬
graphical) are shown in Table VI. Comparisons on the C.P.I.
and Strong tests are facilitated by reference to Figures 5
and 6 which represent High and Low means graphically.
Since the w/onderlic , Lawyer, and le scales are also
relatively discriminating it can be seen that general mental
ability and professional status potential, especially in
interpersonal, communicative fields, most distinguishes the
higher-rated workers from those of lower rating.

Of the 55 female sample variables on which scores
were obtained 26 or 47,3% proved discriminating at the .05
4 7
level of significance. The hypothesis of Part B for the fe¬
male sample is therefore rejected. Discriminating variables
were again distributed throughout the tests given although,
compared to the male sample, were quite sparse on the C.P.I.
which likely accounts for the less than S07q figure attained.
The rank order of these variables is shown in Table 8.
TABLE VIII

RANK ORDER. FEMALE SAMPLE
The more significant were again in the cognitive tests and
interest inventory with the former more discriminating than
in the male sample. Figures 7 and 8 alloiv comparisons of
High and Low means on the C.P.I. and Strong tests.

3. BIOGRAPHICAL VARIABLES AS DISCRIMINATORS
The extent to which the biographical variables dis-
2 criminate between the High and Low-rated groups is shown by X
values calaculated for their dichotomy ratio differences in
Table IX. The discriminative value of ’Education* exceeds
noticeably the other biographical variables, especially in the
less homogeneous male sample where it places higher in rank
order. This variable presumably reflects qualities similar
to those of the more discriminative test variables (e.g. gen¬
eral ability; professional status potential).

Part C. Multiple Regression Analysis
The degree of association between the biographical
variables and the rating criterion is shown in Table X ex-
pressed in terms of point biserial correlations which were
tested for significance from zero with t. Only ’Education’
proved significant, It was therefore considered to be of
potential value as a predictor so included in the intercorre
lation .analysis. The 30 variables selected for regression
analysis by inspection of intercorrelations and criterion
correlations are listed in arbitrary order in Table XI.

It can be seen that the lists are slightly different for males
and females (in addition to tlie Strong differences). On the
C.P.I. the Cs, Wb, Re, and To scales appear to be of predic¬
tive value for the male sample but not for the females while
Sy, So, and Gi were of greater predictive potential for the
latter. For neither sample were N or E listed although the
E minus N derived score is of apparent value in both.
The predictor variables determined by the regression
analysis to account most efficiently for the criterion vari¬
ance are shown with regression coefficients (beta weights),
constants, and proportion of variance accounted for by each
predictor in rank order in Tables XII and XIII, It is seen

Its relatively low position in each (10th place) however
suggests that the other biographical variables would very
likely not have been included had they entered the analysis.
The multiple correlation coefficients are remarkably
high, allowing acceptance of the hypothesis of this Part for
both samples. A large portion of the predictable criterion
variance was accounted for in both samples by the total score
(R) of the Reasoning test, with interest variables PA for the

males and SW for the females contributing the next major por¬
tions. The multiple regression equation for the male sample
takes the form:
Y' , = .0542R + .0388PA +...+.0378Law - 5.6913 M
while that for the female is:
Y’p = .0494R + .0841SW +...-.0569Psy - 4.1542
The standard error of the criterion actually reached
its minimum for both regressions after about fifteen or six¬
teen variables had been entered but contributions beyond the
particular ”cut-off’' points chosen were minute. Direct com¬
parisons of the beta weights are difficult since raw not
standard scores are utilized.
Those variables included in the equations were tested
for the linearity of their relationships with the criterion as
shown in Tables XIV and XV. Of the 24 relationships tested
only 2 (those with female variables Phys and Stng) appear to
be non-linear and at a low level of significance (p = approx.
.05). Were the exact configural formulae for these known the
prediction would be improved only slightly.

16 or 70.0^ of the 23 comparable female variables proved so
(Tables XVIII and XIX). The hypothesis that the majority of
such variables would prove apparently fakable is therefore
accepted for both samples. A significant difference suggests
fakability its in the direction of suitability, not other¬
wise. Thus all variables except those marked with a I are
apparently fakable in the present context. On only one male
regression equation variable, A-J, and two female ones, PEdT
and Psy, does it appear difficult to simulate the higher¬
rated worker's scores. Discriminating variables appear
equally fakable with only Sp, Ai, Py, and Phys for the male
sample proving difficult to distort in the instructed direc¬
tion and Sp, Ai, Fx, Buy, and PhT for the female sample.
Figures 9 to 12 provide evidence for the fakability of other
variables not directly relevant to the present hypothesis but
discussed further in Chapter V.

CHAPTER V
DISCUSSION
PART A, PSYCHOLOGICAL DESCRIPTION OF WELFARE WORKERS
1^. Int elliqence
The similarity of the welfare workers' Valentine
scores to British trainee teachers and Wonderlic scores to
fourth-year American college students would indicate intel¬
lectual ability of about (North American) first degree level.
(British university students represent a higher, narrower
segment of the intelligence continuum and are thus less compar¬
able than the American undergraduates). It might be expected
that graduate social workers would represent a slightly higher
ability level than that indicated for the present welfare
worker samples. Kidneigh and Lundberg (1958) found social
work students had academic interests and abilities similar to
fifth-year psychology, nursing, and education students. Some
difference presumably exists therefore between the welfare
and social worker groups, in this respect at least. Educa¬
tional level is not that sensitive a measure however, for al¬
though males possess less university training than the female
workers, (42% having degrees/diploraas compared with 78,6%)
they achieved scores equal to or higher than the latter.

It is possible that anonymity, which was hoped would
promote typical responses on the non-cognitive tests, did not
promote maximal responses on the ability tests. The reduction
of ’’ego" involvement and inability to learn individual scores
may have depressed motivation, and hence scores, a little,
although probably mostly in the duller Ss. Valentine (1954)
points out that his test requires "not only ability but con¬
tinuous concentration and a keen desire". A number of Ss did
report considerable fatigue towards the latter problems. The
time element in the Wonderlic, too, could prove too much to
"worry" about for the unmotivated. The average scores for
these workers should, therefore, possibly be even a little
higher, but this is speculative. However, to the extent that
workers can apply their capacities in practical situations
more at their own rate such test results may not reflect fully
on-the-job reasoning ability although there is undoubtedly
considerable correspondence.

autonomic reactivity. The bel».)w average N scores achieved by
the welfare workers is not in complete agreement with Sauna
(1963) and Roe (to be published) who found social workers
above average on this trait but does support their findings
that male workers score relatively higher than females. Non¬
professional welfare workers however may represent a less
anxious, less insecure group since they have either not de¬
sired or been able to seek the higher degree. Rettig and
Salomon (1960) found social workers aspire to a higher status
than that accorded them in the professional milieu. Welfare
workers are not in this competative climate to the same degree.
Within their own ranks however the average male welfare workers
could possibly experience some discomfort in an environment in
which the female workers are typically first degree/diploma
holders (while they are not) thus accounting in part for their
relatively higher (though still below average) N scores.
A better perspective of the actual comparability of
welfare worker and normal groups is obtained by noting the
mean scores for certain psychiatric groups, e.g. hysterics -
30.8, psychopaths -35.6, and dysthyraics (the openly fearful,
worried, anxious individual) -38.1, all markedly higher than
either. Standard deviations for the workers proved less than

normals and psychiatric groups suggesting their relative homo¬
geneity in this respect.
The extroversion factor (E) is said to be a measure of
one's outgoing, uninhibited, social proclivities with intro¬
version as its converse. One neurological basis is thought to
be the rate cortical satiation dissipates being low for extro¬
verts and high for introverts. The scores achieved by welfare
workers, placing them between English and American normals,
although consistent with the national stereotype, does not
differentiate welfare workers as a group except insofar as
their standard deviations were again less than the normative
groups. Mean E scores for the psychiatric samples were, when
compared to welfare workers, lower for dysthymics (17.9),
similar for hysterics (24.9), and higher for the psychopaths
(30.8). It is therefore apparent that comparisons are most
meaningfully made on a two dimensional basis, considering both
N and E scores together. Figure 13 shows welfare workers to
fall at a point presumably representing a minimum or absence
of dysthymic-hysteric features, i.e. calm, forthright,
confident.
The correlation between N and E, expected theoretically
to be zero, was -.303 for males and ,142 for females. Eysenck

(1959) reports that slight negative correlations are common
and originally explained this as being due to non-linearity
of the regression lines at low ii values, where N values are
higher than expected. Separate correlations for the sexes are
not reported but possibly mixed populations would separate to
provide values similar to those above. This view is strength¬
ened by recent work of (1) Eysenck and Eysenck (1963) who
found the E scale composed of impulsivity and sociability
items (there being more of the latter) which correlated re¬
spectively slightly positively and slightly negatively with N
and (2) Siegraan (1963) who found E scores correlated positively
with impulsive behaviour in delinquent males but not in delin¬
quent females, postulating a difference in male-female re¬
sponses due to social forces and role expectations. It is
possible therefore that male welfare workers, who tend to
have low N scores if they have high E scores, check a prepon¬
derance of sociability items, especially compared to delin¬
quents, while the female workers check relatively more im¬
pulsivity items, although they average higher E and lower N
scores than the male workers. Thus by adjusting the sociabil¬
ity to impulsivity item ratio on the £ scale orthogonality
with N could result for mixed general populations but

correlations could be either positive or negative for parti¬
cular sub-groups (male, female, or mixed) depending on their
positions on sociability and impulsivity continua.
(b) California Psychological Inventory. A recent,
second factor analysis of the C.P.I. by Mitchell (1963) con¬
cluded the 18 scales or 1st order variables to be inappropri¬
ately labelled in certain cases and to represent mixed attri¬
butes. Five 2nd order factors were obtained which were also
found to underly Cattell's 16 PF test. These were: general
adjustment vs. neuroticism (Wb, Sc, To, Gi, Ac); extroversion
(Do, Cs, Sy, Sp, Sa); intellectual resourcefulness (To, Ai,
le. Re, Py); emotional sensitivity (Fe only); and superego
strength (So, Fx(-)). For the sake of parsimony and integra¬
tion with M.P.I. results some description of welfare workers
will be in these terras. Some justification for this approach
is provided by Stewart (1962) who found psychosomatics low on
all 5 C.P.I. adjustment vs. neuroticism scales but average on
all its extroversion scales. Eysenck (1959) places psychoso-
raatics at N = 35.7 (high); E = 25.4 (average) which is virtu¬
ally equivalent (Figure 13).
Reference to Figure 14 shows the male welfare workers
profile to be relatively flat and slightly above average in

terms of adequate social and inter^jersona 1 functioning. (The
mean profile for a socially inadequate group (prisoners) is
included for contrast). The moderately higher scores on Cs,
Sa, To, and Ai would indicate, in Gough's interpretation, that
the average male worker was "ambitious, forceful, versatile,
communicative, outspoken, fluent, self-accepting, tolerant,
foresighted, and independent". In the main these characteris¬
tics describe Mitchell's two factors of 'extroversion' and
'intellectual resourcefulness'. The relatively low So and
higher Fx scores however indicate a 'superego strength'
possibly below that expected in such a group. However this
"weakness" is even more apparent in the female sample (Figure
15) while the factors of 'intellectual resourcefulness' and
'extroversion' are apparently higher (e.g. Sp, To, Ai, le,).
There would seem to be an inverse relationship in this
occupation between the superego factor and the other two
factors mentioned which may be partially explained by consid¬
ering the terms describing high So and low Fx scores:
"serious, industrious, modest, conscientious, steady, cautious,
rigid, tradition-bound, and conforming" which somehow portrays
insufficient outgoingness and adaptability to characterize to
any extent the requirements of welfare work. The female

sample's "highs" indicate they are even more "enthusiastic,
imaginative, quick, informal, forceful and self-reliant" com¬
pared to women in general than the males workers are compared
to the average man. Direct male to female comparisons are
difficult to interpret.
It may be noted that the female group, with a lower
"superego" pattern has the lower, but still average, general
adjustment pattern (note Wb, Sc, Gi, Ac) in relation to self¬
sex norms. It is as though some freedom, activity, and re¬
sourcefulness are released by a lowering of normally inflex¬
ible "superego" guards only to be accompanied by a raised
anxiety level, which, being slight however, may function
merely as a motivator. The male sample displays this also to
a lesser extent. The apparent inconsistency between the C.P.I.
and M.P.I, "adjustment" findings suggests different concepts
are involved,which no doubt overlap to some extent.
Figures 14 and 15 also allow coxaparisons with the com¬
parable "helping-professions" of nursing and social work. As
might be expected welfare workers place mainly between these
two normative groups in general social behaviour adequacy.
Sp, To, Ac, Ai, Py, and Fx appear to most differentiate the
female social workers and welfare workers from the nurses

while only To and Ai are of similar value for the males. Do,
Sy, Sp, le, Py, and Fx means are considerably higher for the
male social workers than for the welfare workers and aides who
are quite alike in these regards. Educational differences
alone do not appear to account for these patterns. The low
'superego': high 'ext roversion-resourcefulness' relationship
is thus even more marked in social workers than welfare workers,
while the 'adjustment' factor remains (relatively) depressed.
The C.P.I. concept of neuroticism (via Mitchell) may therefore
be more comparable to that provided by the MMPI and 16 PF
tests, on which social workers were also found to be above
average, than that of the M.P.I. on which they were not.
The highest C.P.I. - M.P.I. correlations are between
Sp and E (.56), Sy and £ (.51), and Sa and £ (.53) for females
and also for males, but slightly lower (.41, ,40, and .45 re¬
spectively). C.P.I. class I variables would therefore, as
suggested by Mitchell, appear to represent an extroversion
factor. The correlations between Sc and E ^vere ,02 and -.41
respectively for males and females. Hence, although the
raised proportion of sociability E items, thought endorsed by
male welfare workers compared to delinquents, evidently did
not reflect itself in a greater absolute proportion compared

to female workers, it would appear that the impulsivity pro¬
portion was reduced for males and increased for females, at
least to the extent that these same characteristics are
measured by C.P.I. scales of comparable name.
_3. Int erest s
The mean standard score achieved by each occupation
on its own scale on the Strong is approximately 50. Compari¬
son of mean welfare worker scores to this value on each scale
provides one interpretive approach. Unfortunately pure chance
responding to the Blanks results in varying scores for each
scale hence it is easier to approach 50 on some scales than
others. Inter-scale comparisons should therefore consider
this effect while inter-sample comparisons on any single scale
can be made directly.
Figures 16 and 17 show the mean male and female welfare
worker scores compared with people-in-general and social
workers. The obvious cluster of high scores for the male
sample in the social services category (Group V) are virtually
the only ones reaching the B (score 35) or higher categories.
The fluctuations within this group of occupations appear to
follow the chance response pattern similarly for all thrc„
samples indicating little real meaning in different mean scores

therein for any one sample. Male welfare workers fall a little
short of but approximate social workers' Interests with respect
to working with, guiding, and directing people in their inter¬
personal affairs, when compared to people in general. There
are two other similar areas of comparison: the Psychologist and
Group X occupations which together combine features of inter¬
personal activity with verbal and abstract conceptualization.
Welfare workers have interests that exceed the general public's
in this regard but again fall short of the social workers. The
one other area allowing a meaningful comparison is Group II
(physical science, non-personal) on which this group's inter¬
ests are considerably less than men in general. These findings
are very similar to that reported for social workers by Lewis
(1947) and Gravitz and Mintz (1958) on the Kuder Vocational
Preference Record and by McCornack and Kidneigh (1954) on the
Strong, Conclusions were they liked "contact with people,
verbal activities and disliked physical sciences".
The average female welfare worker displays a pattern
similar to the men with respect to the interpersonal and lin¬
guistic interests underlying the Social Worker, Psychologist,
English Teacher, and Slcial Studies Teacher scales, placing
between the general public and social workers. Scores in the

negative direction, relative to the public, were mainly those
suggesting aversion to commercial, numerical and technical in¬
volvement (e.g. LInS, Buy, MScT, Den and LT scales) which
further characterizes this group as people-oriented rather
than material-oriented. Reflecting this also is their above
average score on the Occupational Therapist scale; the low
Dentist and Lab Technician scores indicating it is the personal
not the material aspects of such an activity that proves
attractive.
4. Biographical Variables
Some interpretation of biographical findings (Tables I
and IV) may be advanced. The fairly equal ratio of male to
female workers could suggest either the welfare field generally
is equally attractive to the two sexes or that particular sec¬
tions of the work call for one sex primarily thus determining
the agency's hiring policy. The larger number of men over
thirty years probably results from the faster attrition rate
for female workers due to marriage and pregnancy in the twent¬
ies. This may also account for the longer length of service
noted for male workers. Finally, the female predominance of
degree/diploma holders is partially explained by the number
of ex-police officers without such qualifications (but

considoi'able "weliai'e" ex[)eriencG) who enter the field upon
retirement from such as the R.C.M.P. There is not a comparable
source of female workers. This may also be a factor in tlie age
discrepancy. Some relevance at this point attaches to Kidneigh
and Lundberg's (1958) conclusions that neither age nor exper¬
ience were important factors in social work students' progress
and proficiency although as a group they were older than those
entering other vocations.
Part B, Psychological Discrimination of High-rated from Low¬
rated Welfare Workers
The degree to which supervisors apparently distinguish
the suitable from the less suitable in this interpersonal
occupation on the basis of intellectual ability primarily is
in agreement with studies of similar occupations e.g. Grygier
(1956), Cuadra and Reed (1957), Cliff, Neivman and Howell
(1959), Rosenburg et al (1962). This quality apparently bears
the major relationship with such a criterion unless, or course,
it was "fallen back upon" by supervisors who found the amor¬
phous nature of this complex criterion prevented more compre¬
hensive ratings. It is to be noted however that it was reason¬
ing ability (mainly deduction) rather than the more general
Wonderlic measure of ability or Educational level that most
discriminated these groups and that three Interest variables

separate the two intelligence measures. This suggests that
comprehensive ratings were ap[>lied, incor{)orating a variety
of suitability facets, possibly assisted by the multi-rater
condition of the study. Consistent with the aforementioned
studies however, personality variables were generally not too
discriminating. This, and the significance of the interest
differences agrees with Abeles (1958) and Severin (1952) who
found non-personality measures predicted rating criteria sig¬
nificantly better than personality measures.
The interest variables most discriminating the male
workers likely represents the interest of the High-rated
workers to organize and guide the affairs of others (PA) with
a minimum of direct control (SW) but in a "professional”
manner (OL). The capacity to also accept supervision them¬
selves however is indicated by the Ac variable proving con¬
siderably more discriminating than Ai (in spite of the higher
score welfare workers obtain on the latter). The similar
value of To again suggests an ability to "get-along" and con¬
form when appropriate. The relatively discriminating Cpt and
For scales (in the negative direction) seems to support this
view: the lower rated workers (who score higher on these
scales) finding it more difficult to tolerate rules and inter¬
personal conflicts, and thus seek the independence these

The M.P.I. scales were moderately discriminating for
the male sample with the derived E-N score more so than either
alone. Male workers are thus presumably relatively heterogen¬
eous with respect to the qualities underlying this value;
highly rated workers obtaining both lower N scores and higher
E scores with the latter apparently weighted more with socia¬
bility than impulsivity items (if one is guided by the High
and Low C.P.I. means on Sy, So, and Sc). He is thus a rela¬
tively calm, secure, other-person oriented individual compared
to the lower rated workers, with the deductive capacities and
interests as stated.
Personality variables (from both C.P.I. and M.P.I.)
were even more superfluous for the female sample discrimina¬
tion, only Ai and Fx proving of moderate value and Sp somewhat
less (Table VIII; Figure 7). Interest variables (Figure 8)
were of greater value, however, with Sw, Psy, Law, and SST
again quite discriminating. The Engr and PEdT scales also
attained relatively high positions in the rank order list
(Table VIII) and could relate to an energetic, active charac¬
teristic in the higher rated female workers. This is reflected
also in the high positions of Ai and Fx which, compared to Ac
and To, prove more discriminating than in the male sample.

Figure 5 shows the consistent, high mean values
for the male High group relative to the Low group, compared
to the frequent reversals of the female profiles (Figure 7),
in particular on So, Sc, and Gi. Thus the (relatively) low
socialization/high impulsivity characteristic noted for the
"average" female welfare worker is even more pronounced for the
"high-rated" female welfare worker. This is seen also in the
similar profile of the graduate female social \vorkers noted
in Figure 15. It is not reflected in a discriminating E or
E-N score however, for this sample, and would suggest that the
sociability to impulsivity item ratio in E did not favour dis¬
crimination for female workers (too few impulsivity items)
while it did for the males, who were evidently discriminated
by the more numerous sociability items in E. Such hypotheses
would require item analyses for verification.
Compared with the low-rated group the high-rated female
worker is thus relatively active, independent, flexible, and
socially unrestricted - these qualities being more important
as discriminators (along with the deductive reasoning ability
and particular interests) than the tolerance, conformity, and
sociability qualities which discriminated the males. Both the
male and female samples could, of course, possess many or most

oi the qualities which are discriminative for the oi)))Osite sex
(except where such qualities are extremes of the same continua).
For example the female workers may possess adequate tolerance
characteristics - but homogeneously.
Part C. Multiple Regression Analysis
An inspection of the variables constituting the regres¬
sion equations (Tables XII and XIII) shows the difficulty in
anticipating which variables account most for independent por¬
tions of the criterion variance. Hence R and W, especially
in the female sample, prove relatively non-overlapping while
le is a further independent contributor in the intellectual
sphere in both samples. Similarly PA, SW, and PD account, in
the male sample for different elements of the suitability
criterion, even though these scales (all Group V) appear to
measure quite comparable factors. SW and YS represent this
situation with the female workers. Although the majority of
the predictors came from the apparently more promising half of
the 30 variables considered for each group, it is noteworthy
that certain less promising variables which possessed very low
correlations with the criterion such as Sa (.22), le (.23) and
E-N (.14) for the females and A-J (.23) for the males, were
more predictive than, for example, Psy (.54) and Law (.49).
Thus neither subjective selection of the one variable

with the highest criterion correlation from each category or
class of variables, nor elimination of all variables with
criterion correlations below some cut-off point, nor variables
displaying the most significant t ratios for High-Low mean
differences, would appear to provide the best estimates of
predictors. These and other intuitive, "face-valid” methods
are however, according to Taylor and Russell (1939), Barthol
and Kirk (1956), Cronbach (1960), often inappropriately util-
izedin non multiple regression selection procedures. Factor
analysis will also indicate the same "best” predictor variables
as multiple regression analyses however (Anderson, 1953).
Even the method herein used to reduce the original number of
variables apparently did not weight the significance of minimal
variable intercorrelation sufficiently, although seemingly
enough to include most efficient predictors. A major diffi¬
culty lies in being unaware of variable-criterion relationships
after the variance due to earlier predictors is accounted for;
even the sign of such relationships may be reversed from the
original as their discriminative value for the male and female
samples. The E-N value, for example, was, when assessed "in
parallel" with other variables, discriminating for males but
not females, but in the multiple analysis the converse holds.

The sociability element was evidently more efficiently repre¬
sented for males in some other scale(s) while for females the
irapulsivity element, though slight, was not.
The regression equations provide an analysis of the
qualities of importance in welfare work which in many respects
overlaps with that provided by the rank order of discriminat¬
ing variables. In the female sample however the position of
Sa (which was not in the rank order list) is noteworthy. This
C.P.I. variable was found by Rosenburg et al (1960) to be the
only non-intellective factor predicting social work course
success in a multiple regression study. It is said to be a
measure of feeling of personal worth which allows independent,
confident thought and action and is scored high by the out¬
spoken, demanding, over-confident, self-centered individual
and low by the hesitant, self-abasing, passive individual.
Figure 14 shows it to be the highest scored scale of male de¬
linquents and thus appears to represent an independent concom¬
itant of unsocialized, impulsive behaviour (note delinquents'
So scores) which is possibly represented in the female regres¬
sion by £-N, hypothesized to be impulsivity-weighted. An
opposite trend is apparently represented in the male regres¬
sion equation (in which Sa is not a factor) by To, high scores

on which indicate a permissive, other-person oriented individ¬
ual. Sa is apparently more discriminating of females (whether
socialized or unsocialized) than males.
The reference here and elsewhere to the "freedom from
superego restraints" which seems characteristic of female
social workers and the more suitable female welfare workers
is not to convey a comparison with the unsocialized delinquent
(from which they obviously differ) but rather the contrast
between male sample and female sample discriminators or pre¬
dictors. The more suitable male welfare worker appears to be
relatively more empathically, socially, and possibly sociably
responsive than lower-rated male workers, compared to such
differences in the female sample. The extent of absolute male-
female differences however, if any, would require further
study to determine.
The possibility of curvilinear predictor-criterion re¬
lationships should always be considered but are frequently
discounted (Ghisselli, 1963). However, Thorndike (1949) and
Ferguson (1959) claim that though possible, they are in fact
rarely encountered in personnel research, Thorndike finding
none in several years of military selection research. A test
of linearity for those predictor variables selected for the
ab
present regression equations was nevertheless made. Results
(Tables XIV and XV) confirm Thorndike's and Ferguson's view
since only two proved non-linear.
Some adjustment for these might be warranted only if
this finding held up in cross-validation and where the multiple
R was reduced to a point w^here improvement following such ad¬
justment was significant. Also, Creager and Miller (1961) found,
in reviewing many regression studies,that no significant con¬
tribution to prediction of leadership criteria vjith cognitive
or non-cognitive measures was made by interaction variables,
while Cronbach (1960) states "nothing is gained by configural
formulas (in any case) unless data are uncommonly reliable".
Thus the linear model for both individual validity coefficients
and for multiple regression equations appears justified.
Since any large pool of items, variables, scales, etc.,
would likely provide, by chance, some which vjere discriminating
for any group of individuals, a "holdout" group or other com¬
parable samples for cross-validation purposes is necessary in
order to determine the degree of shrinkage of the multiple R
values. In the absence of such these may remain spuriously
high (McNemar, 1955). This effect is somewhat neutralized how¬
ever when the original validation sample does not represent
89
that to which the findings may eventually be apjjlied (i.e. a
heterogeneous applicant group) but rather the more homogeneous,
pre-selected employee group.
Part D, Fakability of the Non-coqnitive Tests.
The findings of those studies assessing various tests
fakability were confirmed with respect to the "artificial"
faking situation (Tables XVI to XIX). All measures taken on
the M.P.I. proved fakable with E no more resistant than N
(Figure 13). On the C.P.I. 5 male and 7 female scales were en¬
dorsed in excess of the High-groups while the majority of the
other scales approximately equalled those groups (Figures 9
and 10). Only 5 male (Sp, To, Ai, Py, Fx,) and 4 female scales
(Sp, Ai, Py, Fx) were apparently not scored as ’’much” in the
suitability direction as the High groups. Some scales are thus
available on this test which may be of value even where motiva¬
tion to present typical responses is not maximal.
The Strong scales are remarkably simulated in terms of
the criterion, especially for the male sample, with Groups II
and V in particular closely "copied". (Figures 11 and 12).
The effects of the chance pattern must however be considered;
it tends to promote the semblance of profile similarity and
minimize differences that, under inspection, exist.

The equivalent fakability of the non-discriminative
variables in addition to the regression and discriiuinitive
variables suggests that rather than conclude the tests con¬
cerned to be worthless when certain scores are thought by
testees to be desirable, it may be of value to consider just
how recognizable is such gross faking. When all scales on all
three tests are analyzed a faked pattern emerges. For example,
when compared to the High-group profile a combination of very
low N, high E, very high Gi, high Wb and Sc, low Sp, Ai, and
To, low Avr and A-J, and high YPD and YS in relation to PA
and SW would appear to identify the simulation of concern for
male testees. For females the pattern is similar except that
high Re and So and low Fx are additional C.P.I. signs while
To is not discriminating. On the Strong the SST, YS, Buy,
and LInS are over endorsed while HsW, Off, PT, PEdT, and Engr
score too low by the fakers. Finally, it may be recalled that
some research at least would suggest that "real” situation
faking is minimal.

CHAPTER VI
SUMMARY AND RECOMMENDATIONS
This study has dealt with a psychometric analysis of a
particular category of "helping-profession" - the welfare
worker. Since few similar studies, if any, have been reported,
little information is available regarding the qualities char¬
acteristic of or most suited to this apparently growing voca¬
tion. Five paper and pencil type group tests were administered
to 69 male and 76 female welfare workers and analyzed separ¬
ately for the two sexes. The tests used were: the Maudsley
Personality Inventory, California Psychological Inventory,
Valentine Reasoning Test for Higher Levels of Intelligence,
Wonderlic Personnel Test, and the Strong Vocational Interest
Blank. In addition, different samples of 20 male and 16 fe¬
male workers were given the three non-cognitive tests only
with instructions to attempt to simulate the responses of a
social worker taking such tests when applying for a desired
position in welfare. These samples were referred to as the
Simulation groups and again analyzed separately. All tests
were taken anonymously with scores and ratings aligned by a
coding system.

Four hypotheses were advanced which organized the in¬
vestigation into four somewhat independent sections. The
first, Part A, was concerned with a description of the aver¬
age male and female welfare worker in terms of the variables
measured. The relevant hypothesis stated that 'welfare
workers would achieve scores on the tests given comparable to
the other "helping-professions" but different, in many respects,
from those of such as salesmen, scientists, and the socially
inadequate, where such norms are provided'. This afforded
some structure to the otherwise "shotgun' approach to this
aspect of the study. It was concluded that the hypothesis
could be accepted since welfare workers did approximate the
responses of social workers who, as a group, satisfy the other
stipulations of the hypothesis , although the present samples
also possess characteristics of their own.
Male workers achieved mean scores which would describe
them as of senior undergraduate intelligence, having high in¬
terests in verbal and social service activities and little
interest in technical, scientific, and selling activities,
while being above average in general social behaviour adequacy
and below average in neurotic breakdown potential when under
stress.

Female workers achieved mean scores similar to the men
so may be similarly described. They scored a little lower in
deductive reasoning however, and, compared to women-in-general
placed lower on the neuroticisin scale and higher on measures
of intellectual resourcefulness and extroversion. Their Fx
to So ratio and high Ai score suggested a greater impatience
with social restrictions than the male workers that was some¬
what confirmed by correlations between extroversion and cer¬
tain C.P.I. scales. This was supported also by various inter¬
est findings (e.g. low Librarian, high Phys. Ed. Teacher)
which pointed to an aversion to restriction, inactivity, con¬
formity .
The second section of the study. Part B, was concerned
with identifying test variables which might discriminate the
more suitable workers from the less suitable in terms of a
numerical rating criterion. The relevant hypothesis stated
that 'the difference between test score means of those workers
in the High-rated group and the Low-rated group would be signi
ficant on the majority of dimensions measures’. This was
accepted for the male sample, for which 55.7% proved discrim¬
inating (p = .05), but not for the females, for which only
47.3% proved so. The tests chosen thus appeared to provide

enough variables to justify their selection for the particular
discrimination concerned, although the M.P.I. and C.P.I. were
of less value for the female than male samples.
The most discriminating variable in both samples was
the total Valentine score. It appeared the deduction sub¬
score accounted for more of this position than did induction.
The male sample was discriminated next best by three Strong
scales - SW, OL, and PA while SW, Psy, and Engr were of equiva¬
lent value for the females. The Wonderlie followed next in
both samples while Ac and To for the males and Ai and Fx for
the females proved to be the more discriminating personality
variables but of less value than the aforementioned cognitive
and interest variables.
The higher-rated male workers' scores would thus describe
them as possessing deductive reasoning ability, concentration,
and general intelligence; an interest in helping to administer
people's affairs and problems on a professional level; toler¬
ance; and the capacity to perform under conditions requiring
restraint, to a higher degree than the lower-rated workers.
They possess less interest than the latter in technical, non¬
personal, isolated activities while of course sharing with
them many of the non-discriminating characteristics typical

of welfare workers generally.
The higher-rated female workers appear to possess, to
a greater degree than the lower-rated females, those cognitive
abilities mentioned Above, inductive reasoning, an interest in
working with and understanding people, flexibility, and the
capacity to perform under minimal direction. They possess
less interest in domestic and commercial activities but share
certain of the typical welfare worker characteristics with the
lower rated workers.
The third section of the study, Part C, was concerned
with the determination of multiple regression equations for
the prediction of the criterion. The relevant hypothesis
stated that ’the multiple correlation between the ultimately
selected predictor variables, as weighted in the regression
equation, and the rating criterion would be significantly greater
than zero’. This was accepted for both samples. Of the 74
original male variables 11 were incorporated in the multiple
regression compared to 13 of the original 59 female variables.
Approximately one half of the criterion variance was
accounted for by the total Valentine score in both samples
with PA for the males and SW for the females contributing the
next major proportions. The only personality predictors were

To and le for the males and Sa, E-N, and le for the females.
Some of these male-female differences were again discussed in
terras of restraint and impulsivity. It was noted that antici¬
pation of predictive variables was difficult since it is in¬
dependent aspects of the variance which must be accounted for.
The final section of the study, Part D, was concerned
with the fakability of the non-cognitive tests. The relevant
hypothesis stated that 'the majority of Simulation group mean
scores on those variables shown to discriminate the High/Low
groups or included in the regression equations would either
not differ significantly from or would fall beyond, the com¬
parable High-group mean scores'. This was accepted for both
the male and female samples for which 85.3% and 70.0% of the
pertinent variables were shown fakable respectively. Many
scores not relevant to the hypothesis were also distorted in
the "desirable" direction. It was suggested a "faked-pattern"
analysis would identify such distortion were it to occur in
"vested-interest" situations.
This investigation has thus been an exploratory enquiry
of surface-level phenomena the findings of which should be
considered tentative, especially until a cross-validation study

can be made. Provided one has sufficient subjects, and time,
it would seem that the double cross-validation design, where
each half of the total sample serves as the "hold-out” group
to assess the multiple regression of the other, is the method
of choice in such validation studies. Confirmed findings may
then suggest directions for deeper probes into "helping-
profession" characteristics and motivations, especially of the
non-professional category. Such information could be of value,
for example, in scholastic or vocational counselling situations.
Possible areas for further investigation include anal¬
ysis of the reasons for welfare workers* apparent preference
for personal contact, verbal, and abstract activities and
aversion to the technical, concrete, and isolated fields. It
would be of related interest to determine to what extent their
relatively high social presence, tolerance, and achievement by
independence characteristics are not reflections only of in¬
telligence and/or educational levels. The importance of rea¬
soning ability for those involved in seeking solutions to
personal and social living problems should, since this func¬
tion was given considerable weight by raters, also be explored
further. The use of the Valentine test in studying the more
and less proficient of other "helping-groups" (e.g. nurses)

where problem factors may be less obscured, less intangible
and where more formula-type solutions are expected, would pro¬
vide further comparative norms and thus give more meaning to
present findings.
Further investigation would seem required to clarify,
in particular, the apparent differences (relative or absolute)
between male and female workers with respect to irapulsivity,
independence, and flexibility vs. socialization, tolerance,
and conformity. (These two clusters are not necessarily
"polar" to each other.) Item analyses of the Extroversion
scale plus the administration of other measures of impulsivity
and sociability (and/or their converses) to both socially ade¬
quate and inadequate groups would hopefully assist such an en¬
quiry. A related enquiry might also be made on the male/fe¬
male discrepancy on Sa discrimination, possibly in terms of
Taylor and Combs' (1952) findings that self-acceptance (i.e.
of the reality of one's imperfections) was more characteristic
of the well-adjusted than the maladjusted.
The ambiguous relevance of personality variables gen¬
erally to the helping-professions (compared, for example, to
the role of intelligence) could possibly be clarified by ask¬
ing supervisors to rate workers in terms of suitability.

according to "personality" only, and ignoring as much as
possible intellectual differences (even though the latter, if
incorporated, may markedly alter any comprehensive rating
assigned). Those personality test variables displaying high¬
est correlations with such "restricted" suitability ratings
may thus provide a clearer measure of these characteristics.
Another approach to this problem is that of Norman
(1961) who constructed, from pools of relevant items, tests
which measure only the personality factors determined by
factor analysis to underly rating criteria. Various studies
(e.g. Tupes and Christal , 1958) indicated that the same set
of five personality rating factors invariably emerged regard¬
less of the group rated or rating procedure used. These were
Surgency (get-up-and-go), Agreeableness, Dependable Conform¬
ity, Emotional Stability, and Cultural Appreciation, Factor
analyses of established personality inventories frequently
conclude very similar factors. It would be of interest there¬
fore to instruct raters to rate Ss on these 5 particular dimen
sions as well as on intelligence and interests, separately,
and compare results with the overall rating procedure findings
(The present test battery, which incorporates the factors con¬
cerned, could be utilized.)

The relevance and application of the present findings
or their cross-validated "residue” to other similar situations
requires an estimate of validity generalization. For example,
the slowly-gathered test data available from an applicant
population without the vocational experience of welfare work,
could be correlated with ratings given subsequent to the in¬
fluence of several months of such a milieu. This would allow,
when compared with present results, a measure of such an in¬
fluence, if any existed. In addition, an analysis of such
test profiles for "fake-patterns" could provide evidence
either in support of or contrary to studies suggesting "real-
life" faking to be minimal. The effect of the absence of
anonymity also on cognitive test results could be examined
and compared with that under the anonymous condition.
Finally, it is to be noted that the present research
dealt with the concept of the overall, general welfare worker.
The value of particular traits for particular specialties (e.g.
adoption work, court work, public assistance, ward supervis¬
ion, etc.) is widely recognized. Further research, where the
selection problem extends into the classification problem is
therefore undoubtedly required.

Appendix 1. - Instructions to Raters.
"The department has been asked to cooperate in a re¬
search project designed to provide information about Welfare
Workers. Your assistance is requested initially in providing
individual ratings of each of your worker’s overall suitabil¬
ity and proficiency.
As only general information of an occupational category
is required, and not information of specific workers, you are
asked to randomly assign a code number to each worker selected
from a range of numbers arbitrarily assigned each office.
Ratings (and later other data) submitted will thus be assoc¬
iated with such anonymous code numbers and not with worker's
names.
Numerical ratings are to be used (as if grading out of
100%) but restricted to the particular values 70 to 79.
Please assume that employed elsewhere may be quite adequate
workers v;ho, on this basis, would receive ratings from say 50
to 69, but that we have none in this department. Hence ratings
of 70 and above refer to considerably comp etent workers.
An example of what might be received, therefore, from
an office with 6 workers, assigned the code number range 230-
240 is:
Code Number Rating
231.73
234 . 77
235 . 70
237 . 78
238 . 73
239 . 74
Hence, neither the undersigned nor anyone else could possibly
know to whom any particular rating refers (other than each
supervisor for his own office). For this reason and the fact
that such information can only be utilized for general pur¬
poses, the ratings should not be countersigned by or made
available to the respective workers.

Appendix 1 - (cont.)
Once all ratings are received two short sets of psy¬
chological tests for each worker will be mailed to your office
with any necessary instructions. It is important that as each
unsigned test is completed by a worker, it be handed directly
to the supervisor who will write that worker's code number in
the NAME space, unseen by that or any other worker or staff,
then placed in an evelope to be mailed with other such tests,
to the undersigned. A total of five tests will be sent; one
set of three followed a week later by a set of two. Each set
will require less than a 2 hour session to complete.
The apparent over-concern regarding anonymity is felt
vital in order to guarantee (1) valid, accurate ratings and
(2) honest, uninfluenced test data. It can not be over
stressed that neither the ratings nor the test responses
could ever be related to any one worker or supervisor.
Kindly submit ratings next to appropriate code numbers
on attached form. Select any _ code numbers from the
range _ to _. The only rating criterion is that
of overall welfare worker suitability and proficiency deter¬
mined on the basis of your experience and judgement. Thank
you for your cooperation."
Appendix 2. Instructions to the Major Groups.
"Your department has been asked to cooperate in a re¬
search project designed to provide information about Welfare
Workers. This will involve the completion of five psychologi¬
cal tests to be aistributed in two sets. All necessary in¬
structions for these are as printed on the tests themselves.
They should not bq perused until actually commenced nor dis¬
cussed with others who have yet to complete them. Your super¬
visor will arrange for the timing of the two tests which
have time-limits.
It is important that all workers realize that this re¬
search seeks to discover the true interests, personalities, and
abilities of Welfare Workers generally and does not seek in¬
formation of specific individuals. For this reason you are
asked to not identify yourself by name on any of the answer
sheets. However, since test results are to be correlated with
proficiency ratings, a coding system is being utilized to align
tests and ratings, the latter having been already obtained,
identified only by such code numbers. Hence neither this re¬
searcher nor any higher administrative staff could determine
the specific source of any particular test or ratings.
Supervisors have been asked to place each completed
test in an evelope immediately after writing (out of all
workers' view) the appropriate code number in the blank name
space. Only your supervisor should know to whom any particu¬
lar code number (or rating) refers. They will then be mailed
directly to the researcher. Since these tests will be en¬
tirely anonymous, it is hoped each worker will allow as true
a reflection as possible.
Cooperation with Regional Offices, thus far excellent,
is very much appreciated. Thank you."

Appendix 3. - Instructions to Simulation Groups.
"A research project which has involved the completion
OX' five psychological tests by welfare workers in the larger
regional offices, is presently underway.
The final phase of this project requires the collec¬
tion of a smaller number of three of the tests used which are
to be purposely completed in a faked manner. Workers in the
smallest regional offices are being requested to complete
these three tests, anonymously.
Specifically you are asked to complete the tests as
you tlilnk xvould most guarantee your acceptance as an applying
welfare worker with the knowledge that such test results were
to be taken into consideration. In other words you are asked
to purposely fake in a particular direction - even though, in
a real application situation you personally might not distort
your responses at all. Try to imagine you are the world's
most mature, educated, warm, outgoing, stable, professional
social worker and answer the questions accordingly.
The three tests to be completed are: (1) Maudsley Per¬
sonality Inventory; (2) The California Psychological Inventory
and (3) The Strong Interest Test. These will be provided by
your Supervisor. They should not take more than 2 hours to
complet e.
Thank you for your cooperation."
