Abstract
The purpose of this analysis was to create a scale that measures the psychological construct of conscientiousness. Subsequently, the goal of this scale was to be implemented as a method utilized in the selection process in the workplace. This report documents the processes that took place in this analysis, along with the results found. Results of this analysis show that conscientiousness is significantly associated with Mechanical Ability (r = .70, p < .05) along with Turnover intentions (r = .37, p < .05), and Integrity (r = .35, p < .05). Additionally, when Conscientiousness as a scale is compared to the current scales within the selection method at the electrical company, it accounts for the highest amount of variance of Turnover Intentions (β = .39, p < .05).
3Conscientiousness Scale Development Project
Content Analysis
As defined, Conscientiousness is a psychological construct, which is comprised by being
industrious and orderly. As a result, I would expect items related to commitment, efficiency, and
knowledge along with orderliness, tidiness, completeness, and a personal need for rules and
schedules to load very well onto the construct of conscientiousness. Other variables that the
items should address include high impulse control, self-motivation, and need for approval. As
researchers such the traits mentioned above are often associated with the psychological construct
of conscientiousness (Goldberg et al., 2006; Madhavan, 2004; Roberts, Chernyshenko, Stark, &
Goldberg, 2005; Salgado, Moscoso, & Berges, 2013).
By implementing an operational definition that covers a wide range of traits, but is not to
the point of excessiveness, I believe the content validity of the definition to be high. By including
traits that apply not only in everyday life, but also traits that transfer to situations apparent in
organizational settings also suggest for high content validity.
Based on the content domain, items that were considered to be beneficial items for the
construct of conscientiousness include:
C11. I like to keep my surroundings organized and neat.
C13. I plan task according to importance
C22. I double-check tasks for correctness.
C24. When given a task, I always complete the task in an efficient and precise manner rather than procrastinating or pushing the task off to another individual.
These items were considered beneficial due to each item including information from
more than one trait within the construct of conscientiousness. For example, on item 13 it includes
4Conscientiousness Scale Development Project
information which encompasses both traits in the industrious and orderly category, such as
efficiency and orderliness.
Based on the content domain, items that were considered to be poor items when
measuring the construct of conscientiousness include:
C2. I often work after hours to make sure I complete a project on time.
C4. I don’t work as hard as the people around me.
C16. I think before I speak.
C21. I do what I think is right in the workplace.
C23. I am more likely to go to a pre-planned event than a last minute event.
These items were considered poor items due to vagueness, content irrelevant information,
or item which only suggest at traits within the construct, rather than including information of the
actual traits. For example, on item 23 it is suggesting at a need for schedule which is included
under orderly, but the item is making a broad accusation by stating they are more or less likely to
go to an event that was or was not scheduled.
Currently, I am not convinced the measure is content valid, although I believe
implementing a few major and minor changes could increase it drastically. In the current scale,
when the items are categorized by the trait or traits addressed in the question, the majority of
items are associated with Orderly, with only a few items addressing Industriousness. Also there
are only a few items which encompass both Industriousness and Orderly within the same
question. By implementing these few content changes, I believe content validity could be
increased.
5Conscientiousness Scale Development Project
The limited minor corrections would include changes to the poor items that could be
accomplished through rewording of the item. Such changes would make the items less vague and
more content relevant rather than using the original versions. Additionally, by making changes to
the display of the response options, the participant rating could be easier and more accurate. For
example in the current version the ratings of “strongly disagree to strongly agree” are displayed
on the diagonal, which makes misinterpretation possible and also could be uncomfortable for the
participant when completing the scale.
Factorial Validity
Based on the construct of conscientiousness, I expect to see a three-factor structure, since
the nature of the definition is based off of two main traits (Industriousness and Orderly) along
with one of the three additional traits included in the definition (Impulse Control). For
Industriousness I would expect to see commitment, efficiency, and knowledge to load as sub-
facets. For Orderly I would expect to see orderliness, tidiness, completeness, and a personal need
for rules and schedules to load as sub-facets. For impulse control, I would expect items related to
self-control and thorough evaluation to load as sub-facets.
As indicated by TableA1, the scale of conscientiousness (N of items = 25) has a high
reliability estimate (α = .86). Items that would increase alpha level if deleted include: RS4
(increase of .007), item 5 (increase of .003). Others include items 7, 14, and 23 (all of which
increased alpha by .002) (See Table A2). Reliability was conducted twice after the initial analysis
which included all 25 items, first with items RS4 and 5 eliminated, then secondly with items
RS4, 5,7,14, and 23 removed. As indicated by Table A4 reliability is the highest (α = .87) when
items 4, 5, 7, 14, and 23 are eliminated as compared to only eliminating items RS4 and 5 (See
6Conscientiousness Scale Development Project
Table A5). Number of participants included within the analysis (N = 61) also increases as
compared to the number of participants included in the original reliability analysis (N = 55) due
to participant exclusions.
An exploratory factor analysis was initially conducted without defining the number of
factors, then secondly by defining the number of factors. After conducting these analyses, it was
determined that the number of factors that best fit the sample of data was three (See Table B2 &
B3). By having a three factor structure, this enabled the scale to retain the maximum number of
items possible as compared to the other factor structures conducted. The items that loaded on
factor one include C18, C19, C21, and C22. The content of these items included a need for rules,
ethical behavior, and double checking tasks for correctness. As a result, factor one was termed
Need for Rules and Ethics. The items that loaded on factor two include C1, C6, C15, C16, and
C17. The content of these items included information on impulse control, detail-orientation, and
self-motivation. As a result factor two was termed Self Discipline. The items that loaded on
factor three include C9, C10, C11, and C12 (See Table B1). The content of these items included
a preference for organization and order. As a result factor three was defined as Orderly.
In regards to homogeneity of the scale, as researchers suggest, homogeneity refers to
unidimensionality of a scale (Cortina, 1993). As the nature of the conscientiousness scale is
multidimensional, this suggests the conscientiousness scale is not homogeneous.
The factor structure which I expected before conducting any analyses was a three factor
structure consisting of Industriousness, Orderly, and Impulse Control. The observed factor
structure after conducting a factor analysis was quite different that such initial expectations.
Although the factor structure which fit the data most appropriately was a three factor structure,
7Conscientiousness Scale Development Project
the factors of Industriousness, Orderly, and Impulse Control did not. The only factor out of these
expected factors was Orderly. Along with this factor Need for Rules and Ethics, and Self
Discipline were the observed factors after analysis. Despite my misinterpretation of the expected
factor structure as compared to the actual observed structure, the majority of variables in the
observed analyses were expected before such were conducted. For example, the only variables
which were not included in the initial expectations were detail oriented and need for ethical
behavior. Based on such information along with the high reliability of the scale I still believe the
factorial validity to be fairly high. Despite the number of items which were removed due to non-
significant factor loadings or cross loading, there are still a substantial amount of items which
still adequately measure conscientiousness although the factor loadings may not be as clear cut
as initially expected. Additionally I believe this scale of conscientiousness could have vast
implications for the interview process at a local electrical company along with various other
organizational settings, by further examining and screening potential employees to best fit the
position and organization.
Construct Validity
Based on the results displayed in the correlation matrix there are relationships between
conscientiousness and other measured variables that are somewhat expected. The variables that I
expected conscientiousness to be highly related to include Integrity, CWB, and Turnover
Intentions, in addition to being moderately related to OCB and Task Performance. These
variables could be included as within the scale to measure evidence of convergent validity. In
contrast I would expect conscientiousness to be highly unrelated to variables such as Interview
and GMA, in addition to being moderately unrelated to Mechanical Ability. Variables such as
these could be included with in the scale as measures of discriminant validity.
8Conscientiousness Scale Development Project
In comparison to the expected relationship between conscientiousness and related
variables, the observed relationship between conscientiousness and related variables include
Mechanical Ability (r = .70*), Turnover Intentions (r = .37*), Integrity (r = .35*), CWB (r
= .33*), OCB (r = .29*), Task Performance (r = .26*), and GMA (r = .25*), which vary
somewhat from my original expectations. The only variable included within the measure that
was relatively unrelated to conscientiousness was Interview (r = .12*), which was consistent with
my original expectation. The main association which I did not expect, but was observed was that
of Conscientiousness and Mechanical Ability (r = .70*). Surprisingly, this particular variable had
the highest correlation (r = .70*) as compared to the other variables included within the measure.
Although the relationship theoretically makes sense, I would not have expected it to have the
strongest association between conscientiousness when compared to other variables such as
Turnover Intentions (r = .37*) or Integrity (r =.35*), both of which I expected stronger
associations. Additionally I would have expected that CWB (r = .33*) and Task Performance (r =
.26*) to have a stronger association. With these observed associations in mind and despite the
intention of generalizability of this measure, I do not feel confident with generalizing the results
of this measure to other professions especially ones which require little mechanical ability. Using
the measure in such professions could not only affect employee scores but also work behavior.
Although I trust this measure could be highly beneficial for use in a local electrical company and
other organizational settings that require a high amount of mechanical ability.
Criterion-Related Validity
In regards to the regression analysis conducted on Job Performance with GMA, Integrity,
Interview, and Conscientiousness as predictors, 45% of the variance in Job Performance was
accounted for by the predictor variables. The two predictor variables that accounted for the most
9Conscientiousness Scale Development Project
variance (as indicated by the β values) were GMA (β = .39*) and Interview (β = .25*).
Additionally, Conscientiousness as a predictor variable (β = .09*) accounted for the least amount
of variance as compared to the other variables. Note. * p < .05.
The regression analysis conducted on Turnover Intentions with GMA, Integrity,
Interview, and Conscientiousness as predictor variables, as displayed by, 60% of the variance of
Turnover Intentions was accounted for by the predictor variables. The two predictor variables
which accounted for the highest amount of variance (as indicated by the β values) were
Conscientiousness (β = .39*) and Integrity (β = .29*). Additionally, GMA as a predictor variable
(β =.15*) accounts for the least amount of variance in Turnover Intentions as compared to the
other variables included. Note. * p < .05.
Our measure of conscientiousness fared extremely well either as a 25 item scale (α = .86)
as a 20 item scale (α = .87), as compared to other scales measuring conscientiousness; as
demonstrated by IPIP scales such as the AB5C 12 item scale (α = .75), NEO domain 10 item
scale (α = .81), Big Five Domain as a 10 item scale (α = .79) and as a 20 item scale (α = .88)
(Goldberg et al., 2006).
With conscientiousness having such a low beta value (β = .09*) I believe there is little
unique variance accounted for by conscientiousness within the criterion domain of Job
Performance. In contrast, conscientiousness has a much higher beta value (β = .39*) on the
criterion domain of Turnover Intentions. As a result, I believe there a moderate amount unique
variance accounted for by conscientiousness within Turnover Intentions. Note. * p < .05.
The results of the regression analysis on Job Performance indicate that 45% of the
variance is accounted for by the four predictor variables (R² = .45, F = 32.5, p < .05).
10Conscientiousness Scale Development Project
Additionally the results of the regression analysis on Turnover Intentions indicated that 60% of
the variance is accounted for by the four predictor variables (R² = .60, F = 30.03, p < .05). Based
on the moderately high variance value as compared to a high amount of variance accounted for, I
do not feel that multicollinearity is an issue that we should be worried about.
Based on the results reported in the regression analysis, I feel our measure of
conscientiousness would be most appropriately used in the selection process when trying to
determine a level of Turnover Intentions rather than a level Job Performance or both Turnover
Intentions and Job Performance. Additionally, with results in the regression analysis, the
correlation among constructs also suggests conscientiousness is a better predictor of turnover
intentions rather than job performance.
Recommendation
It is my official recommendation, given the results of the current form of the
conscientiousness scale and the internal problem of turnover within the electrical company, to
implement the conscientiousness scale within the selection method process. The different sources
of evidence that influenced my decision include the reliability of the conscientiousness scale, the
correlation among constructs, and the regression analyses conducted on Job Performance and
Turnover Intentions. Not only is the conscientiousness scale highly reliable (α = .86) but when
compared to other conscientiousness scales it also fares well. As indicated by the regression
analyses, along with the correlation of constructs, conscientiousness is also significantly
associated with constructs such as Mechanical Ability and Turnover Intention. Both of these
constructs apply specifically to the organizational setting of the electrical company. More
specifically, when compared to other selection methods (GMA, Integrity, and Interview),
11Conscientiousness Scale Development Project
conscientiousness accounts for the highest amount of variance in Turnover Intentions. By
including this scale within the current selection methods, I feel confident that it will help solve
the issues with high turnover, especially when compared to solely relying on the current methods
of selection.
In comparison of base rates of the current selection method (.70) with the predicted base
rate once the conscientiousness scale is added (.90), it may not initially seem like much of a
difference, although it is suggested the higher the value of a base rate the higher the probability
those selected will be good performers. Additionally, when comparing adverse impact between
selection methods, there are disparities it both tables. By implementing the conscientiousness
scale the overall hiring ratio decreases, which could have the possibility to be beneficial by
having a higher probability of hiring employees that are better fit, although this probability also
affects the instances of adverse impact which are projected to increase as compared to the
original assessment. Adverse impact in the current scale, when comparing ethnicity, the
percentage of employees hired through external and internal means are 50% for white applicants
as compared to only 30% of African American applicants. In contrast, when this hiring
percentage is examined after implementing the Conscientiousness scale, the percentage of
employees hired though external and internal means (when comparing ethnicity) is 48% for
white applicants as compared to 20% of African American applicants.
Adding the conscientiousness scale to the current selection method is financially and
practically feasible. Since this scale only takes roughly ten minutes to complete and can be
distributed to a large group at once or through the use of secure online portals, it eliminates the
need for someone to physically administer the measure in cases of online distribution, or in the
case of mass administration it eliminates the need to administer the measure on an individual
12Conscientiousness Scale Development Project
basis. With the elimination or at least a decrease in cost of scale administration this measure is
financially feasible, even with the limited budget of the electrical company. Along with most
scales measuring a psychological construct, there is always a possibility for participant response
error whether it occur for social desirability reasons, careless or random responding, or just flat
out answers without regard to item content. In our case, especially if a participant feels the
results of the measure could negatively affect their well-being, the conscientiousness scale could
very well be interpreted as such. I do not feel concerned with faking on this scale although if it
ever does become an issue, by managing the testing context it is possible to prevent or minimize
the existence of such bias.
Raw data Interpretation
As displayed in Table A10 the only significant correlation between scales is between
Protestant Work Ethic and Conscientiousness (r = .44, p <.01) along with a correlation between
Protestant Work Ethic and Turnover Intentions (r = .11) and a correlation between
Conscientiousness and Turnover Intentions (r = -.17). Theoretically the observed correlations
between scales do make sense. For instance, items on the PW scale include traits such as ethics
and self-disciple which also load very highly on Conscientiousness. Additionally, the negative
relationship between Conscientiousness and Turnover Intentions makes sense; these results
suggest if one is highly conscientious they are less likely to have high turnover intentions or vice
versa. With conscientiousness as a trait, it is suggested that individuals are more likely to aware
and concerned about the well-being of the organization and in turn less likely to have high
turnover intentions.
13Conscientiousness Scale Development Project
When initially screening participants, the criterion used for eliminating participants was
based on employment status and employee tenure. In regards to employment status, participants
were eliminated if the occupation was either left blank, if they indicated they unemployed, if
they indicated they were a student, or if they indicated a part time/as needed or seasonal job as
their occupation. Thus by eliminating participants based on these criterion, although it decreases
the participant sample size, I feel by doing so the data will be a more accurate representation of
the sample, in addition to making the sample size more generalizable to various organizational
settings.
Reliability was conducted for all scales used within the conscientiousness measure. Using
this particular analysis, on the Protestant Work Ethic scale (α = .67) along with the values
displayed within Cronbach’s Alpha if deleted table is the criterion for determining item retention
of the scale (See Table A 7 & 9). Due to the limited number of items within the original scale (N
= 8), the moderately high reliability value (α = .67), along with none of the items loading on the
Alpha if deleted, it was decided to keep all the items of the original scale. Reliability was
conducted on the Turnover Intentions Scale as well (α = .87). This analysis along with the values
displayed within the Cronbach’s Alpha if deleted table, is the criterion used for determining item
retention of the scale (See Table 8 & 10). Similarly to the PW scale, due to the limited number of
items (N = 3) in the original TI scale, the high reliability value (α = .87), along with only one of
the items (TI2) loading on the Alpha if deleted (with α = .03 increase), it was decided to keep all
of the items included with in the original scale. As discussed previously, reliability was
conducted on the conscientiousness scale (α = .86) (N = 25) due to the values displayed within
the Cronbach’s Alpha if deleted table items C4, C5, C7, C14, and C23 were eliminated (See
Table A1 & 4). Additionally, the reliability was conducted following item elimination, although
14Conscientiousness Scale Development Project
there is an increase in reliability (α = .87) (N = 20) it is extremely small. Based on these results,
the elimination of said items is up for personal interpretation of the researcher using the scale.
In addition to these analyses, the demographics of the sample were also conducted (N =
87). As indicated by Table C2, the majority of participants were white (65.5%), were between
the age of 20 and 24 (62.1%), were single (67.8 %), and had been at their current job roughly for
12 months (8%). In comparison of occupational groups, the vast majority of the sample was
either employed by the service sector (33%) or by an academic sector (31%) (See Table C3).
Additionally when comparing participants due position as indicated by Table C4, the majority of
participants indicated themselves as other (47.1%) or at an entry level (33%).
Based on the sample population, the highest numbers of participants were employed
within the service sector (N = 29), although the sample size of this study could have real
implications regarding the generalizability of the scale. Additionally, the participants that
indicated they were in a service sector position, does not specifically indicate they were in a
customer service position, which could also influence the generalizability of this scale. I do
believe the Conscientiousness scale to be a reliable and valid measure, although I would be
cautious when interpreting the results of this study and generalizing them to a specific
occupation.
