The main aim of the study was to replicate a previous study into personality factors associated withconfessions and denials. It was hypothesised that antisocial personality traits and active involvement incriminal behaviour would be associated with false confessions and false denials. The participants were 666university students in Iceland. Each was asked about false admissions made to teachers and parents in thepast, as well as about confessions or denials (true and false) made to the police during questioning. Theparticipants completed questionnaires relating to offending and personality. One-quarter (25%) of theparticipants stated that they had in the past been interrogated by the police in relation to a suspected offence,of whom 54% said they had confessed. The base rate of guilt in the study of those interrogated by the policewas 66%. Only two participants (1.2% of those interrogated) claimed to have made false confessions to thepolice, whereas 6.2% claimed to have made false confessions to teachers or parents at some time in their lives.False confessions to teachers and parents were significantly associated with antisocial personality traits and theextent and seriousness of self-reported delinquency. In conclusion, antisocial personality characteristics,impulsivity, and the extent and seriousness of self-reported delinquency were the most significant predictors ofwho had a past history of making false confessions to teachers and parents.

INTRODUCTION
When investigating crimes, one of the methods that the police have at their disposal is to
interview suspects in order to obtain a confession. When suspects confess to the crime of
which they are suspected, then their self-incriminating admissions are often used against
them in court (Gudjonsson, 2003). On occasions, denials, when shown to be false, can also be
used against defendants to prove their guilt in court (Leo, 1996).
In England about 60% of suspects confess to the police during interviewing, whereas in the
USA the rate is about 45% (Gudjonsson, 2003). What remains relatively unknown and
under-researched is the base rate of true confessions, false confessions, true denials and false
denials, respectively, among suspects and how these different outcomes relate to suspects’
personality. This four-group distinction about the outcome of a police interview was first
articulated in Gudjonsson’s (2003) book The Psychology of Interrogations and Confessions. A
Handbook . The book shows how the focus of research on police interviewing has been

mainly on confession rates and on the nature of false confessions. Little research has been
carried out into denials, true or false.
There are a number of models available to explain confessions. Gudjonsson (2003) reviews
six such models: ‘The Reid Model’ (Jayne, 1986); ‘A Decision-Making Model’ (Hilgendorf
and Irving, 1981); ‘Psychoanalytic Models’ (e.g. Reik, 1959); ‘An Interactional Model’
(Moston et al. , 1992); ‘A Cognitive�/Behavioural Model’ (Gudjonsson, 1989a); and ‘The
Ofshe�/Leo Model’ (Ofshe and Leo, 1997). Whereas the first four models focus principally
on the psychological factors behind true confession, the Cognitive�/Behavioural Model and
The Ofshe�/Leo Model are applicable to both true and false confessions.
Two further models are available, which are exclusively relevant to false confessions.
Firstly, the best-known model of false confessions is that of Kassin and Wrightsman (1985),
where false confessions are seen as falling into three psychological types: voluntary, coerced-
internalised and coerced-compliant. Recently, Gudjonsson (2003) proposed a modification
to the threefold typology of Kassin and Wrightsman, changing the word ‘coerced’ to
‘pressured’ and adding a category that indicates the source of pressure (i.e. internal,
custodial, and non-custodial).
Some important overlaps exist between the different models, although each makes
somewhat different assumptions about why suspects confess to the police during question-
ing. In broad terms, suspects confess when they perceive that there is strong evidence against
them, when they need to relieve feelings of guilt, when they cannot cope with the custodial
pressure, and focus on the immediate consequences of their actions rather than the long-term
ones. Although the suspect’s personality is considered important in some of the models in
producing confessions and denials, the nature of the specific vulnerabilities and traits are not
articulated, except in relation to suggestibility and compliance (Gudjonsson, 2003).
Compliance is theoretically most associated with the pressured-compliant type of false
confession and suggestibility in relation to the pressured-internalised type.
The research of Gudjonsson and Sigurdsson (1994) and Sigurdsson and Gudjonsson
(1996a) among Icelandic prisoners showed that 12% of the inmates claimed to have made a
false confession some time in their lives to the police. Among this sample, antisocial
personality characteristics, such as poor socialisation, and active participation in criminal
behaviour from a young age were good predictors of their reporting having made false
confessions (Sigurdsson and Gudjonsson, 2001). There is also a good reason to believe that
those who attempt to deny their true criminal involvement during interrogation are likely to
possess antisocial personality traits (Gudjonsson and Sigurdsson, 1999). Both types of
behaviour (i.e. a false confession and a false denial) involve suspects lying for some
instrumental gains (Gudjonsson et al ., 2004).
In a recent study of 1080 young college students (age 15�/25 years) in Iceland, Gudjonsson
et al . (2004) studied confessions and denials among 268 participants who reported that they
had been interrogated by the police on one or more occasion in their lives. The base rate of
guilt in the study among those interrogated was 67%, 59% claimed to have made a true
confession to the police, and 3.7% claimed to have made a false confession to the police. The
confession rate among those who were truly guilty of the offence was 81%, which means that
19% of guilty suspects denied the offence (i.e. they were false deniers). With regard to false
confessions, 10% claimed to have made a false confession to teachers or parents in the past.
False confessions and false denials were found to be significantly associated with antisocial
personality traits. Those participants who made true confessions and true denials were most
normal in their personality.
126 G. H. GUDJONSSON et al.
The purpose of the present study was to investigate differences in the personality and
offending behaviour of persons who made confessions or denials when interviewed by the
police, according to the four confession-denial categories listed above. Whereas previous
research has focused on police detainees (e.g. Moston et al ., 1992; Gudjonsson et al ., 1993),
or prison inmates (Gudjonsson and Sigurdsson, 1994; Sigurdsson and Gudjonsson, 1996a,b,
1997, 2001), the present study involved interviewing representative groups of college students
who are known, from our previous research (Gudjonsson and Sigurdsson, 2004), to have a
high level of self-reported offending and some involvement with the police. On the basis of
the literature (for a review of the literature see Gudjonsson, 2003), we hypothesised that
those persons who make false confessions to the police, as well as those who make denials of
offences they have committed (i.e. false deniers), are more likely than true confessors and
true deniers to: (a) be disordered in their personality (e.g. possessing antisocial personality
characteristics); and (b) have an extensive history of delinquency and offending. We also
hypothesised that persons with a history of making false confessions to parents and teachers
would be more antisocial in their personality than the other participants, and to be more
likely to make false confessions to the police.
The present study is a replication of the previous study, but it is carried out among
university students rather than a broad range of students in further education in Iceland.
This is an older and a better-educated group, whose offending, in contrast to college
students, is more strongly associated with serious traffic violation (e.g. driving whilst
intoxicated) rather than property offences and acts of violence (Gudjonsson and Sigurdsson,
2004).
In science, replication of research findings is important. In the present study replication is
particularly important, because in the original study several of the findings were stunning
and potentially of considerable theoretical and practical importance. This includes the high
rate of involvement of the college students with the police and in criminal activities, the
theoretical and practical implications of the distinctions between confessions and denials
(both true and false) and the respective base rates, and the significant relationship of false
confessions and false denials to antisocial personality characteristics.
METHODS
Participants
The participants were 666 university students in Iceland. There were 332 (49.8%) males and
329 (49.4%) females in the study (Information on gender was missing for further five (0.8%
of the participants)). The average age for the sample was 24.02 (range 19�/48, SD�/4.0).
Instruments
1. The Eysenck Personality Questionnaire (EPQ; Eysenck and Eysenck, 1975; Haraldsson and
Bjornsson, 1985)
This 101-item questionnaire, which has been translated into Icelandic and standardised
(Eysenck and Haraldsson, 1983) measures three main personality dimensions (Psychoticism
(a�/0.59), Extraversion (a�/0.84), Neuroticism (a�/0.80), and socially desirable response
set (Lie Scale; a�/0.74)).
PERSONALITY IN RELATION TO CONFESSIONS AND DENIALS 127
2. The Adult Impulsivity, Venturesomeness and Empathy Questionnaire (IVE; Eysenck and
Eysenck, 1991)
This is a 54-item questionnaire measuring three personality traits, impulsivity (a�/0.78),
venturesomeness (a�/0.81) and empathy (a�/0.70).
3. Gough Socialisation Scale (Gough, 1960; Megargee, 1972)
This 54-item scale is one of the best self-reported measures of proneness to anti-social
behaviour (Blackburn, 1993) and measures the extent to which individuals have internalised
the values of society. The lower the score the more likely the person is to possess antisocial
personality traits (a�/0.68).
4. Gudjonsson Compliance Scale (GCS; Gudjonsson, 1989b, 1997)
This is a 20-item scale that measures the propensity of the person to go uncritically along
with requests made by others, largely in order to please others or to avoid conflict and
confrontation. The GCS was developed for two different purposes. First, to identify persons
who are susceptible to making a false confession under interrogative pressure. Secondly, to
identify those who are susceptible to being pressured into crime by peers and others. It is the
second purpose of the GCS which is relevant to the present study (a�/0.71).
5. The Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965)
This 10-item scale consists of positive and negative self-appraisal statements rated on a four-
point scale ranging from ‘‘strongly agree’’ to ‘‘strongly disagree’’. Scores range from 10 to 40
with higher scores reflecting low self-esteem (a�/0.86).
6. Self-Reported Delinquency Scale (Mak, 1993)
This scale consists of 34 items that assesses various delinquent acts. These range from minor
antisocial acts (e.g. cheating games machines, truancy from school, drinking alcohol under
age in a public place, consuming soft drugs) to more serious acts (e.g. forcing somebody to
have sex against their will, using weapons in a fight, setting a fire to damage property,
physically assaulting somebody, theft, driving a vehicle whilst intoxicated). The participants
are asked to indicate whether they had engaged in any of the delinquent acts in the past 12
months and these make up nine offence domains or subscales. In the present study the nine
subscales were not used, because the primary purpose of the study was to focus on the extent
of delinquency as measured by the Total Offending Score (TOS) devised by Sankey and
Huon (1999). This is based on the seriousness rating of each of the scale’s 34 items by judges
from different backgrounds (i.e. police officers, teachers, lawyers, psychology students). The
mean seriousness score for each item is multiplied by the participant’s response to each item,
giving a range of scores from 0 to 474. In the present study, a Serious Offending Score (SOS)
was also calculated according to a formula devised Sankey and Huon (1999), by adding the
mean seriousness score for the seven most serious offences (i.e. beating others, weapon fight,
forced sex, drunk driving, fire setting, burglary, blackmail).
7. Background, Interrogation and Confession Questionnaire (BICQ)
The BICQ is a 19-item questionnaire developed specifically for the purpose of this type of
study, which provided background information about each participant, including age,
gender, substance abuse problems, false confessions made to teachers and parents, reasons
for the false confessions, times spent in a police cell over night, being interrogated by the
128 G. H. GUDJONSSON et al.
police about a suspected offence, the type of offence interrogated about, whether or not he or
she committed the offence, with whom the offence was committed, whether there was a
confession or a denial made, the main reasons for making a confessions or a denial, giving a
false confession to the police during questioning, the reasons for making a false confession,
and the reason why he or she was being questioned by the police in relation to the false
confession.
Procedure
Students taking a course in forensic psychology at the University of Iceland administered the
questionnaires as a part of their practical course work. The participants were approached
either individually or in small groups and asked to participate in a study that was concerned
with self-reported offending and its relationship with attitudes and personality. They were
told that their responses were anonymous and confidential.
The tests were administered in the following order: Mak Self-reported Delinquency Scale,
Background, interrogation and confession questionnaire, Gudjonsson Compliance Scale,
Gough Socialisation Scale, Eysenck IVE, EPQ, and the Rosenberg Self-Esteem Scale.
RESULTS
Offending and Type of Offence
According to the results of the Mak Self-Reported Delinquency Scale, out of the 666
university students, 645 (97%) reported that during the previous 1 year they had committed
at least one offence as listed within the scale. The mean Total Offending Scores for the males
and females were 42.9 (SD�/33.4) and 35.5 (SD�/23.5), respectively. This difference
between males and females was significant (t�/3.31, d.f.�/659, p B/0.001). The Serious
Offending Scores were 5.4 (SD�/10.4) and 3.5 (SD�/7.9) for males and females, respectively.
This difference was significant (t�/2.60, d.f.�/659, p B/0.01).
Interrogation and Confessions
Table 1 gives the frequencies with which the university students had been interviewed by the
police, the number who had confessed during questioning, the base rate of guilt during
questioning, and the number of participants interviewed who claimed that they had made
false confessions to the police at some time in their lives. The figures for the university
students in the left column are compared with those found in our previous study of the
college students (Gudjonsson et al ., 2004). The figures for those interrogated, those who
confessed, and the base rate of guilt, are very similar to those found in the previous study.
The false confession rates during interrogation were 1.2% vs 3.7% for the university and
college students, respectively. The only significant difference between the two samples related
to the higher false confession rates given by college students to parents and teachers (6.2% vs
10.4%).
Out of the total sample, 165 (24.8%) said they had been interrogated by the police on one
or more occasion in their lives. The interrogation figures for males and females were 108
(33%) and 57 (17%), respectively. The gender difference is highly significant (x2�/20.61,
d.f.�/1, p B/0.001). The great majority of the participants (n�/102, 64%) said they had only
PERSONALITY IN RELATION TO CONFESSIONS AND DENIALS 129
been interrogated once, 35 (22%) twice, 22 (13%) more than twice, and seven did not state
how often they had been interrogated by the police.
The most common types of offence for which the participants had been interrogated by the
police were: serious traffic violation (41%); property offences (22%); criminal damage (17%);
drug-related offences (5%); and violent offences (4%). The majority (61) said they had
committed the offence in the company of others.
The confession rate for the 165 persons interrogated was 53.7% (n�/88), with the
corresponding confession figures for males and females being 64 (59%) and 24 (43%),
respectively. There were significant gender differences with regard to whether or not the
person made a confession during interrogation (x2�/3.21, d.f.�/1, p B/0.05).
The base rate of guilt for those interviewed by the police was 66.3% (n�/110). The figures
for males and females were 69% (n�/75) and 61% (n�/35) for males and females,
respectively. This difference was not significant (x2�/0.92, d.f.�/1, NS).
The rate of confession was 86 out of 110 (78%) for the participants who said they had
committed the offence; the corresponding figures for males and females were 85% (64 out of
75) and 69% and (24 out of 35), respectively. The gender difference is significant (x2�/4.21,
d.f.�/p B/0.05).
In the present study only two participants who had been interrogated by the police claimed
that they had made a false confession, one was male and one was female.
Differences in Personality Between the Confessors and Deniers
Table 2 gives the mean and standard deviation test scores for the true deniers, true
confessors, and false deniers. As there were only two false confessors in the study their mean
scores were left out of the table. One-way ANOVA showed significant differences on two of
the test scores: Venturesomeness (F�/6.0, d.f.�/2, p B/0.01), and Mak Total Offending Score
(F�/3.2, d.f.�/2, p B/0.05). With regard to the Venturesomeness score, the significant
difference lies between the true confessors and true deniers (ScheffeB/0.01), whereas for the

Mak Total Offending Score the significant difference was between true confessors and false
deniers (ScheffeB/0.05).
A discriminant function analysis of all the test scores between true deniers and false
deniers showed that one of the test scores, the Mak Total Offending Score, discriminated
significantly between the two groups (Wilks’ lambda�/0.918; F (1,88)�/7.82, p B/0.001).
This suggests that those respondents who were most actively involved in offending had the
greatest tendency to deny their offence.
False Confessions to Teachers and Parents
When asked about past false confessions to wrongdoings (e.g. theft, damage to property) to
teachers or parents, 41 (6.2%) claimed to have made such confessions. There was no
significant difference between the males and females (x2�/0.62, d.f.�/1, NS), with 23 (7%) of
the males and 18 (5%) of the females stating that they had made false confessions. When
asked about the reasons for having made the false confession, 24 (59%) said they had done it
to protect somebody else; the rest said that they could no longer recall the reason (29%) or
blamed it on pressure from others (12%).
In order to investigate the personality factors that are associated with making a false
admission to teachers or parents, the two groups (i.e. those who had made admissions versus
those who had not) were compared on the psychometric tests. The results are shown in Table
3. There were significant differences between the two groups on most of the tests, including
the EPQ (Psychoticism, Extraversion), the IVE (Impulsivity, Venturesomeness), the Gough
Socialisation Scale, and the Mak Self-Reported Delinquency Scale (Total Offending Score,
Serious Offending Score). A discriminant function analysis of all the tests in Table 3 showed
that four of the tests discriminated significantly (Wilks’ lambda�/0.913; F (4,604)�/14.5,
p B/0.001) between the two groups. These were the Gough Socialisation Scale (Wilks’

Therefore, antisocial personality characteristics, impulsivity, and the extent and seriousness
of self-reported delinquency were the most discriminating factors between the two groups.
DISCUSSION
The finding that almost 25% of the participants reported having been interrogated by the
police is identical to the figure found in our previous study among young college students
(Gudjonsson et al ., 2004). In addition, the confession rate obtained by the police, the base
rate of guilt, and the rate of false confession were similar for the two groups. What mainly
differentiated the two groups of students were the number of false confessions given to the
police and to teachers and parents; the rate of false confession to parents and teachers was
significantly lower among the university students. One likely explanation is that the
university students were less actively involved in criminal activities than the college students,
as well as being less antisocial in terms of their personality.
The relatively high rate of true deniers (i.e. one-third of those interrogated by the police) in
the present study emphasises the importance for the police not to ignore the fact that they
may be interviewing a reasonably high proportion of people who are actually innocent of the
crime of which they are suspected. This finding has important implications for police
practice.

The present findings provide further evidence that false confessions to wrongdoings to
teachers and parents, and to criminal acts during police interrogation do occur. In our prison
studies (Gudjonsson and Sigurdsson, 1994; Sigurdsson and Gudjonsson, 1996a) the reported
rate of false confession during police interrogation was 12%. In the present study the false
confession rate was 0.3% for the entire sample, but 1.2% for those who had been interrogated
by the police. The latter figure can be more meaningfully interpreted, because this gives the
percentage of suspects who confess during interrogation. The findings suggest that only a
small proportion of suspects make false confessions during questioning. In spite of this, the
figure is considerably higher than some writers suggest (e.g. Cassell and Hayman, 1998).
Interestingly, and perhaps not surprisingly, false denial was 15% in the present study and is
therefore much more frequent than false confessions.
Unlike in the previous study, males were no more likely than females to have made false
confessions to teachers and parents. In addition, females were significantly less likely than
males to confess to crimes of which they were guilty.
The explanation for the gender difference in relation to false confessions to the police is
likely to reflect the greater involvement of males than females in delinquency and criminal
acts. Support for this view is found in the studies of Gudjonsson and Sigurdsson (1994) and
Sigurdsson and Gudjonsson (1996a), where false confessions were more commonly found
among female than male prison inmates. This suggests that when females are as actively
involved in criminal behaviour as males they are more susceptible than males to make a false
confession. Females in both of the prison studies were particularly likely to confess falsely to
protect somebody else.
The findings on the reasons given for the false admissions to teachers and parents, and
false confessions to the police, show that the great majority of false confessions are given,
apparently voluntarily, by young people in order to protect somebody else.
From the point of personality testing, the findings are clear and consistent. Abnormal
personality traits, and particularly high EPQ Psychoticism and poor socialisation, are highly
predictive of who makes false confessions and false denials. In contrast, the two groups with
the most normal personality pattern, and the least self-reported history of offending, were
true confessors and true deniers. This appears to reflect the differences in the nature of the
groups (i.e. true confessions and true denials versus false confessions and false denials) and
their personality (i.e. antisocial personality traits), probably reflecting fundamental
differences in the groups’ attitudes towards truthfulness and lying. Although those
participants who reported having made false confessions were most disordered in their
personality, their personality traits, and extent of previous offending history, were consistent
with those of false deniers. Both groups appear to tell lies, whether making false confessions
or false denials, as a way of coping with a particular predicament. The implication is that
both groups may, given the right circumstances and perceived instrumental gains, alternate
between making false confessions and false denials. These are overlapping groups who are
prepared to lie to the police for their own ends. Whether there is a false confession or a false
denial probably depends on the circumstances and perceived gains at the time.
The findings in this community study corroborate those of Sigurdsson and Gudjonsson
(1996a, 1997, 2001) that giving false confessions during interrogations is significantly related
to antisocial personality characteristics and criminal lifestyle. It supports the view that the
great majority of false confessions, including those given to teachers and parents, are aimed
at protecting somebody else rather than resulting from external pressure and coercion. This
type of false confession is undoubtedly different from those coerced by the police and where

psychological vulnerabilities relating to low IQ, suggestibility, compliance and anxiety are of
considerable importance (Gudjonsson, 2003). The main differences between the present
community study and the previous prison studies relate to the relatively greater influence of
poor socialisation, as measured by the Gough Socialisation Scale, rather than EPQ
Psychoticism in the prison sample, and the absence of the influence of compliance, as
measured by the Gudjonsson Compliance Scale. Of course, one must take into account the
small number of alleged false confessors in the present study.
One important limitation to the study is that it is based on self-report data. There is no
independent corroboration available about the participants’ involvement with the police,
about their confessions or denials, or about the confessions they report making to teachers
and parents. In addition, the psychological tests administered are all based on self-report.
In future research it would be helpful to obtain copies of the participants’ criminal records
to verify their involvement with the criminal justice system.
