Psychiatric group dimensions within the pen structure

A method is described for constructing two-dimensional diagrams in which psychiatric group dimensions are represented within the PEN structure of Eysenck personality theory. Applied to the Eysenck data, it seems to give a clearer and more vivid picture of the relationships between the P, E and N dimensions and the various psychiatric categories.     

Extraversion,neuroticism, and psychoticism in Iranian students1

A Persian translation of Eysenck's extraversion, neuroticism, and psychoticism inventory (PEN) was given to 209 university and 101 high school students in Iran. Comparisons of the mean scores on extraversion, neuroticism, and psychoticism between the two age groups do not show any significant differences, although the high school students appear to score higher than university students on all three personality dimensions. Comparisons of reliability estimates determined separately for the two age groups suggest that the PEN is equally reliable for high school and university students. The results are discussed in their cross-cultural context.     

Assaultive behavior personality and personal space

Eysenck's Psychoticism, Extraversion and Neuroticism (PEN) Inventory was used to explore the role of personality variables in augmented personal space required by assaultive offenders. For both violent (n = 20) and nonviolent (n = 20) subjects personal space was greatest from a rear approach. Neither personality scores nor nature of offense alone predicted personal space needs; however personal space was significantly elevated in all directions for assaultive offenders with high scores on the psychoticism scale of the PEN Inventory.     

The spiral aftereffect and personality

Reported duration of the spiral aftereffect was correlated with scores on the four scales of the Eysenck Personality Questionnaire and with the Psychoticism (P) scale from the unpublished PEN Inventory. There was a strong positive correlation between PEN P and duration. None of the other correlations approached statistical significance.     

Rate of offending,risk-evaluation and risk-preference

Delinquency is a form of risk-taking. Delinquents might therefore be expected to be either attracted by risks or to be less inclined to notice them. Previous research (Eysenck and McGurk, 1980) has suggested that delinquents do not have a distinctive risk-preference but that they are less likely to evaluate risks. The present study related individual in risk-preference and risk-evaluation to the rate at which delinquents commit offences. High-rate offenders by both high risk-preference and a tendency not to evaluate risks before acting. Possible reasons for the discrepancy between these results and those obtained by Eysenck and McGurk are considered.     

Personality factors in the taking of criminal risks

The present study investigated the relationship between personality and Expectancy of Gain (Egn) and Likelihood of Action (L/A) in criminal situations. The latter variables were assessed by means of an inventory of hypothetical criminal-risk situations. Groups of offenders and non-offenders were tested; personality measures included the Eysenck Personality Questionnaire and Zuckerman's Sensation-Seeking Scale. Theoretical reasons for expecting these dimensions to be related to criminal risk-taking are presented. A clear relationship was found between P and Egn, high scorers viewing situations as less risky. In contrast, N was associated with increased risk perception. The results for L/A were less clear, although generally in the predicted direction. SS was unrelated to either risk variable.     

An evaluation of the relationship between Gray’s revised RST and Eysenck’s PEN: Distinguishing BIS and FFFS in Carver and White’s BIS/BAS scales

Recent revisions of Gray’s reinforcement sensitivity theory (RST) have important implications for self-report measures of approach and avoidance behaviours and how Gray’s model relates to other personality models. In this paper, we examine the revised RST by comparing Carver and White’s (1994) original one-factor solution of the BIS scale with two alternative two-factor solutions separating BIS-Anxiety and FFFS-Fear. We also examine the relationships between Eysenck’s PEN and revised RST factors. Two hundred and twelve participants completed Carver and White’s BIS/BAS scales and Eysenck’s Personality Questionnaire-Revised. Confirmatory factor analyses of the original BIS scale showed that the hypothesized two-factor model of BIS-Anxiety and FFFS-Fear was the best fit to these data. Associations between the revised RST and Eysenck’s PEN were examined using path analysis. In line with theoretical predictions, Psychoticism was related to revised BIS-Anxiety and BAS, Neuroticism to revised BIS-Anxiety and FFFS-Fear, and extraversion to BAS and FFFS-Fear. Distinctions between BAS subscales and their associations to BIS, N and P were made in terms of past, present and future focus. Possible explanations for mixed findings in the literature and implications for future research are discussed.     

A quantitative review of the relations between the “Big 3” higher order personality dimensions and antisocial behavior

In this meta-analytic review, Hans J. Eysenck’s theory of criminality (Eysenck, 1964, Eysenck, 1977) serves as a theoretical framework for examining the relations between higher order personality dimensions and antisocial behavior (ASB). The three higher order dimensions examined are referred to as extraversion/sociability, neuroticism/emotionality, and impulsivity/disinhibition (see Sher & Trull, 1994), and they are likened to Eysenck’s dimensions of extraversion (E), neuroticism (N), and psychoticism (P), respectively (Eysenck & Eysenck, 1975) and Tellegen’s dimensions of positive emotionality (PEM), negative emotionality (NEM), and constraint (reversed) (CON), respectively (Tellegen, 1982). Ninety-seven samples, from 52 published and unpublished studies, were reviewed. The results indicated that among the “Big 3” personality dimensions, impulsivity/disinhibition is most strongly related to ASB and extraversion/sociability is least strongly related to ASB. Additional variables, including age and methodological differences, were found to moderate the associations between the personality dimensions and ASB.     

The relation between anger and antisocial beliefs in young offenders

The tendency for youth to report antisocial beliefs has been identified as a major risk factor in delinquency. Advances in emotion research suggest the importance of examining the emotional concomitants of cognitive appraisals such as antisocial beliefs. The present study examined the relation between anger and antisocial beliefs in a sample of young offenders and investigated whether scores on either variable differentiated aggressive from non-aggressive offenders. Twenty-two aggressive and 20 nonaggressive young offenders were compared on two questionnaires measuring anger and antisocial beliefs, respectively. The findings revealed a significant correlation between the two measures. In addition, it was found that the aggressive offenders, compared to their non-aggressive counterparts, scored significantly higher on anger and antisocial beliefs. These findings extended previous research on the characteristics that differentiate aggressive and non-aggressive offenders. Results also support the rationale for incorporating both cognitive and affective components in intervention programs designed for aggressive young offenders.     

Lifeguards and Physically Risky Prosocial Groups: A comparison based on personality theory

The goal of this study is to explore the personality of experienced professional lifeguards in terms of Eysenck and Eysenck's PEN model of personality and Zuckerman's sensation seeking trait. A sample of 144 male professional lifeguards were contrasted with three different samples: (1) a general population sample; (2) a sample of individuals engaged in physically risky sports; and (3) a sample of prosocial physically risky professionals. It was found that lifeguards resembled most closely the prosocials followed by the sportsmen and finally the general population. The most frequent and largest differences between lifeguards and the comparison groups were found on extraversion, experience seeking, and neuroticism. The implications for lifeguard selection procedures and future research are discussed.     

A cross-cultural comparison of personality: English and Austrian children

The Junior Eysenck Personality Questionnaire was given to 457 boys and 431 girls in Austria. Factor comparisons indicated that the dimensions of psychoticism, extraversion, neuroticism, and social desirability were identical in Austria and in England. Minimal item changes were required to produce a viable Austrian scoring key with satisfactorily high reliabilities for all dimensions except in the case of P for girls, which was somewhat weaker. Austrian norms indicated that boys score higher than girls on P and E but lower on N and L. Direct cross-cultural comparisons revealed few marked personality differences between Austrian and English children, there being a slight tendency for the former to score higher on psychoticism, extraversion and the lie scale but slightly lower on neuroticism.     

The medico-legal status of young sex offenders: forensic psychiatric evaluations in Sweden 1988-1995.

Young sex offenders (YSOs) attract significant public and professional concern. YSOs might be perceived as more psychologically deviant or dangerous than other offenders. This study focused on how often YSOs subjected to forensic psychiatric investigation (FPI) were declared medico-legally insane as compared to young non-sex offenders and adult sex offenders. Logistic regression models were applied to data from all major FPIs performed in Sweden between 1988 and 1995 (N=4354) to explore factors affecting the likelihood of receiving a medico-legal insanity declaration. When we adjusted for the statistical effects of age, sex offender status, and psychopathology, YSOs (n=47) were three to four times more likely to be declared insane in the medico-legal sense. The results indicate that YSOs in Sweden constitute a medico-legally distinct subgroup of forensic psychiatric examinees.     

The relationship of extraversion,neuroticism, and sensation-seeking to questionnaire-derived measures of nervous system properties

Five obliquely rotated factor analyses were performed on items from Eysenck and Eysenck’s (1975) EPQ, Zuckerman’s (1975) Sensation-Seeking Scale, and Strelau’s (1972) temperament inventory (STI), administered to 277 subjects (Ss). The analyses were used to examine the relationships between the personality dimensions E, N, L, P and Sensation-Seeking, which pertain mainly to social situations, attitudes and feelings, and questionnaire-derived measures of nervous system properties, which, while validated on experimental indices of nervous system properties derived from Nebylitsyn’s (1972) model, are expressed as characteristic features of social behavior, work style and activity. Four factors were identified—extraversion/strength of excitation/mobility; self-control of affect/stability/caution; strength of inhibition/verbal control/motor expressiveness/ nonmanipulativeness; and sensation-seeking/nervousness. The results offer support for Eysenck’s claim of some identity between excitatory strength and E, for the reported relationship between E and mobility, and for Eysenck’s conditioning postulate. They also suggest that similar temperamental variables underlie individual differences in both social and occupational/motor activity. Since Strelau’s STI items are validated on experimental indices of nervous system properties, it follows that typological characteristics may be inferred from questionnaire data derived from both behavioral categories.     

Subtypes of adolescent offenders: affective traits and antisocial behavior patterns

Etiological models of life-course persistent offending often emphasize behavioral explanations. Suggestions that persistent offenders have psychopathy ignore the distinct non-behavioral features of the psychopathy disorder. Using a three-factor model of the PCL-YV and cluster analysis with 259 incarcerated adolescents, we identified four distinct juvenile subtypes on the basis of affective, interpersonal, and behavioral dimensions. Prospective and retrospective comparisons of antisocial behavior patterns found the cluster comprising all three psychopathy dimensions to be the most chronic and severe. Impulsive features alone were strongly associated with severe antisocial behaviors retrospectively, but not prospectively. Findings rebut the proposal that disruptive behavioral and impulsive symptoms can identify "fledgling psychopaths." Assessments that disregard callous-unemotional traits will likely result in high false positive rates among serious adolescent offenders. Implications for developmental models of chronic offending are discussed in light of the need for further follow-up into adulthood.     

Authoritarianism and social distance attitudes towards offenders released from prison

It was hypothesized that authoritarian individuals maintain attitudes of greater social distance towards (a) violent offenders, (b) violent young offenders, (c) non-violent offenders, and (d) non-violent young offenders released from prison. Correlations of scores on Boehm's Legal Attitudes Questionnaire for the offender groups supported the hypothesis. Subjects were 48 students in management science. Apparently high authoritarians would like to maintain attitudes of greater social distance from violent offenders than non-violent offenders released from prison.     

Cognitive functioning,personality variables and academic achievement of hemophilic and normal children: A comparative study

The present study was conceptualized in the context of the psychosocial needs of Hemophilic children and adolescents of Kolkata. Twenty four Hemophilic children and adolescents were compared with a matched group of normal controls to find out any specific difference in terms of visuomotor gestalt functioning, intellectual level, academic achievement and personality dimensions. Academic achievement was assessed by averaging the results of the last three consecutive school examinations. Intellectual functioning was assessed by Progressive Matrices by Raven, and personality dimensions were assessed by Junior Eysenck Personality Questionnaire. Chi square tests and ANOVA were conducted to determine whether the Hemophilic children differed significantly from the normal controls across age levels. Findings revealed that there was little difference between the two groups in terms of intellectual level, and most dimensions of personality, although the Hemophilics fared worse than normals in neuropsychological, social and academic aspects. Implication for intervention is discussed.     

Goldberg's bipolar measure of the Big-Five personality dimensions: reliability and validity

A study was conducted to examine the relations between a recently developed measure of the Big-Five personality dimensions (Goldberg, 1992) and several other instruments: the Eysenck Personality Inventory (Eysenck and Eysenck, 1968), the Personal Attributes Questionnaire (Spence and Helmreich, 1978), and the Masculine Behavior Scale (Snell, 1989). The results indicated that Goldberg's Big Five questionnaire was correlated in predictable ways with these personality instruments. In addition, other results revealed that the Extraversion, Conscientiousness, and Emotional Stability scales on Goldberg's questionnaire were associated with a measure of psychological symptoms. The discussion focuses on how these findings provide corroborative evidence for the reliability and validity of Goldberg's bipolar adjective measure of personality traits, thereby supporting this instrument as a reliable and valid measure of the Big-Five personality dimensions.     

Are juvenile offenders extreme future discounters?

It has been the prevailing view that young offenders are more present oriented than their peers, but this view has little empirical basis other than the actions that have defined these youth as offenders. In the present study, we used a decision task with actual monetary consequences to assess the tendency of young offenders and a control group of high school students to discount the future. The young offenders were not significantly different from the students in discounting the future, even though the young offenders scored significantly higher on a sensation-seeking personality scale, were less likely to have lived with their fathers, and had changed schools more often. Young offenders and control participants were also similar in the extent to which they manifested a clear vision of the future by anticipating which future milestones would occur sooner, in a task pairing milestones with each other and with year markers.
