A new approach to Eysenck's theory of criminality

Studies examining Eysenck's theory of criminality by contrasting delinquent and non-delinquent groups have produced equivocal results. Some studies have shown criminals to score higher, as the theory predicts, on psychoticism, neuroticism and extraversion, whilst other studies have not. The current study examines the theory from a new approach by using cluster analysis to demonstrate the heterogeneity of personality types in delinquent sample (N =100) and in a comparison group (N = 100).Four personality types were found in each group. Two personality types which were present in the delinquent sample were not found in the comparison group. The first type consisted of individuals scoring high on neuroticism and extraversion whilst the second type consisted of individuals scoring high on psychoticism, neuroticism and extraversion. These types appeared to be consistent with Eysenck's theory of criminality.     

Learned Resourcefulness,Drinking, and Smoking in Young Adults

The purpose of this study was to examine the relationship between learned resourcefulness and two common addictive behaviors, namely, drinking and smoking. Male and female college students (N = 175) completed the Self-Control Schedule (SCS), the Quantity-Frequency-Variability questionnaire, and a smoking history form. Learned resourcefulness was related to self-reported patterns of alcohol consumption; specifically, heavy drinking subjects were lower in learned resourcefulness than were light and moderate drinkers who, in turn, were lower in learned resourcefulness than were infrequent drinkers and abstainers. Learned resourcefulness was only modestly related to smoking, with students who had never smoked evidencing somewhat higher learned resourcefulness than ex-smokers and current smokers. Overall, these data provide correlational support for the notion that learned resourcefulness may protect young adults against substance abuse.     

Examining Spouse/Partner Presence as a Moderator in the Relationship Between Mental Health Symptoms and Alcohol Use in OEF/OIF Veterans

Veterans from the conflicts in Afghanistan (Operation Enduring Freedom; OEF) and Iraq (Operation Iraqi Freedom; OIF) have reported elevated rates of alcohol consumption, and greater depression and posttraumatic stress disorder (PTSD) symptoms are associated with increased alcohol use. Presence of a spouse/partner, which has been associated with reduced drinking, may buffer the relationship between mental health symptoms and alcohol consumption. To examine this hypothesis, the current study utilized baseline survey data from OEF/OIF veterans (N = 325) enrolled in a brief alcohol intervention. Spouse/partner presence moderated the relationship between depression symptoms and alcohol consumption such that depression was positively associated with drinking for veterans without a spouse/partner. Exploratory analyses indicated that the relationship between depression and alcohol use may be particularly salient for veterans without a spouse/partner and a lower number of deployments. Spouse/partner presence did not moderate the relationship between PTSD symptoms and alcohol consumption. Implications of the findings are discussed.     

The Eysenck psychoticism dimension and delinquent behaviours among non-criminals: changes across the lifespan?

This study assessed relationships between scores on Eysenck's psychoticism (P) scale and delinquent behaviours among high school and university students. Respondents were 347 high school students (M AGE=15.34 years) and 220 first-year university students (M AGE=19.11 years). There were notable differences across the two groups. Whereas most delinquency items correlated significantly with P among the school students, this was not the case among the university students. It is concluded that, while the P scale predicts most delinquent behaviours among younger respondents, it best predicts more serious delinquent behaviours among non-criminal adults. The results are discussed in the context of previous research using the P scale.     

Intimate Partner Violence and Drinking among Victims of Adult Sexual Assault

Intimate partner violence (IPV) is associated with problem drinking. Correlates of alcohol consumption frequency and problem drinking were examined among female sexual assault survivors (N = 1,863). Data were analyzed with blockwise multiple regressions. Results show heavy alcohol consumption and problem drinking were associated with IPV history, sexual assault by strangers or acquaintances, and maladaptive coping. Physical IPV history and partner sexual assault showed distinct effects on drinking outcomes among women. Physical IPV history partially mediated the effect of childhood sexual abuse (CSA) on problem drinking. Research is needed to examine the relationship between victimization histories and drinking among female sexual assault victims. This might enable treatments and interventions to be tailored to the trauma histories of female victims.     

Early antecedents of spouse abuse

Males taken into police custody for reported spouse abuse (n = 19) and a matched control group (n = 19) were asked to describe the drinking habits of their parents and the extent of intra-family violence witnessed by them as children. The retrospective data were compared to the participant's own present alcohol use and aggressiveness (CTS). Excessive paternal drinking and intra-family violence were recalled significantly more often by the spouse abusers than by the controls. A latent structure model suggested that the accumulated violence history was less well predicted by either paternal violence or present aggressiveness than by the direct and indirect effects related to drinking. Context-specific social learning could explain why the parental drunken violence behavior pattern witnessed by the child was repeated by the adult spouse abuser. Aggr.

Extraversion,Neuroticism, and Psychoticism as Measured by Eysenck's Inventories in Iran

Summary

This paper presents results obtained with a slightly modified version of the Persian form of the EPI (PEPI) which also included Eysencks' recently published psychoticism scale. Subjects were 1009 Iranian secondary school graduates (768 boys and 241 girls) aged between 18 and 20 years taking the Pahlavi University entrance examination. Retesting of a small group of subjects under ordinary conditions showed little distortion of the mean scores that might be attributed to the highly competitive test situation. The test retest reliability of the scales over a five-month period, however, was undesirably low, except for the N-scale. The P-scale was found to correlate positively with neuroticism. Iranian female subjects had scored higher than their male counterparts on neuroticism but lower on both extraversion and psychoticism. In comparison with British norms, Iranian subjects had scored higher on both N and P scales, the difference on the latter being particularly striking. These findings are discussed in the light of earlier findings with the PEPI and some tentative explanations for the observed national differences are suggested.     

Psychometric vs. attentional correlates of early onset alcohol and substance abuse

Adolescent inpatients with a diagnosis of alcohol abuse (n=28), nonalcohol substance abuse disorders (n=15), or psychiatric disorders without substance abuse (n=46) were examined on measures of attentional, intellectual, and personality functioning. High scores on a personality measure, the Substance Abuse Proclivity Scale (SAP), was the best predictor of substance abuse in general. Alcohol abusers were differentiated from other substance abusers by their increased impairment on the Continuous Performance Test. Adolescents with alcohol abuse did not manifest the types of cognitive impairments associated with chronic alcoholism. These data suggest that certain attentional impairments may be associated with early onset alcohol abuse and that earlier conceptions of the role of attentional impairments in risk prediction for alcohol abuse are supported.This research was supported by the Four Winds Foundation.

Personality and Religion Among Music Students

A sample of 422 students attending courses in eleven departments or colleges of music completed the short form of the Revised Eysenck Personality Questionnaire together with the Francis Scale of Attitude toward Christianity and measures of prayer and church attendance. In comparison with the population norms, both male and female music students recorded significantly higher scores on the extraversion scale and significantly lower scores on the psychoticism scale. The data confirm that psychoticism is the dimension of personality fundamental to individual differences in religiosity.     

Learning techniques for alcohol abuse

Eighteen month follow-up data are presented for two projects evaluating the effectiveness of learning techniques for treating alcohol abuse and achieving moderation using three groups of subjects-inpatient alcoholics, outpatient alcoholics and problem drinkers. Subjects received various combinations of the following procedures: videotape self-confrontation of drunken comportment, blood alcohol concentration discriminating training, aversion training for overconsumption, avoidance practice, behavior counseling and alternatives training, and alcohol education. While the loss of subjects was considerable between 12 and 18 months follow-up, the data were very similar. Subjects in all groups improved in terms of reductions in alcohol intake and on drinking-related variables. Significant between-groups differences in favor of subjects whose training included actual experience in drinking moderately were found only for the inpatient alcoholics. In this research, the best candidate for moderation was the less chronic. younger drinker with a relatively lower alcohol intake, a more stable vocational record and no history of hospitalization for alcohol abuse or physical deterioration from drinking. We believe that the techniques with the greatest potential for the prevention and treatment of alcohol abuse are videotape self-confrontation, blood alcohol discrimination training, and alcohol education/alternatives training.     

Rates of abuse in body dysmorphic disorder and obsessive-compulsive disorder

Body dysmorphic disorder (BDD) continues to challenge professionals due to symptom severity, co-morbidity, suicidal ideation, and overvalued ideation. Despite the disorder's severity, little research exists. Clinical observation suggests a noteworthy history of abuse; therefore the present study investigated the reported rate of physical, sexual, and emotional abuse in BDD patients. OCD patients were chosen as a comparison group because BDD is considered to be an obsessive-compulsive spectrum disorder. A group survey design was used (N = 50 for each group). Results show significantly higher levels of emotional and sexual abuse in the BDD sample versus the OCD sample. No significant differences were found in physical abuse. Abuse may be a contributing factor in BDD, but not in OCD.     

Some personality correlates of self-rated academic success.

Using subjects' own ratings of their academic performance, a group of american university students were divided into academically successful (n = 312) and unsuccessful (n = 170) subgroups. A comparison of mean scores of the two groups on nine personality variables convered by Eysenck's PEN Inventory and Lanyon's Psychological Screening Inventory showed that academic success, as rated by subjects themselves, is associated with low psychoticism, neuroticism, and discomfort but high extraversion and defensiveness.     

Family,School, and Peer Influences on Alcohol Abstinence and Use among American Indian and White Female Adolescents

This analysis is informed by social bonding, social learning, and self-control theories and is based on data collected between 2009 and 2013 in 27 school districts located in five U. S. regions. The sample (N = 2,140) includes female adolescents (7th–12th graders) who identified themselves as white or American Indian. In support of the social learning theory, pro-alcohol use definitions, association with peers who drink excessively, and the peers’ differential reinforcement of alcohol abuse are significant predictors of alcohol use in the racially integrated model. Conversely, when controlling for a selected group of predictors, one’s level of self-control and measures of social bond are no longer differentiating alcohol users from abstainers. Yet, additional mediation analyses show that the lack of family attachment, parental monitoring, and school attachment have significant indirect effects on alcohol use.     

Conceptual expansion and creative imagery as a function of psychoticism

The ability to be creative is often considered a unique characteristic of conscious beings and many efforts have been directed at demonstrating a relationship between creativity and the personality construct of psychoticism. The present study sought to investigate this link explicitly by focusing on discrete facets of creative cognition, namely the originality/novelty dimension and the practicality/usefulness dimension. Based on Eysenck's conceptualisation of psychoticism as being characterised by an overinclusive cognitive style, it was expected that higher levels of psychoticism would accompany a greater degree of conceptual expansion and elevated levels of originality in creative imagery, but would be unrelated to the practicality/usefulness of an idea. These hypotheses were confirmed in 80 healthy participants who were contrasted based on their EPQ psychoticism scale scores. Our findings suggest that the link between psychoticism and creativity is based on associative thinking and broader but weak top-down activation patterns rather than on goal-related thinking.     

Personality and reciprocal inhibition theory: The link between aggression and sexual reactivity

The study tries to relate two approaches often discussed in the context of aggression and violence in combination with sexual arousal, the reciprocal inhibition theory (Wolpe, 1958) and an approach from personality psychology which emphasizes the psychoticism dimension (P) according to Eysenck and Eysenck (1975) as a mediator of violent sexual offence. The effects of preexposure to a violent vs. neutral movie on sexual reactivity to violent and non-violent sexual stimuli (audioplays and pictures) was studied in a male student population (N=64). Sexual reactivity was measured by self-ratings, inspection time and electrodermal activity. Results could not confirm reciprocal inhibition theory but revealed that sexual reactivity for subjects scoring high vs. low on the psychoticism/aggressiveness dimension were differently affected by preexposure to violence.     

Childhood Physical Abuse and Sociopathy: Is This Link Magnified among Firstborn Children?

The Psychopathic Deviate scale of the Minnesota Multiphasic Personality Inventory–2 (MMPI–2) provides a valid psychometric index of sociopathic tendencies in both clinical and nonclinical samples. Childhood physical abuse has provided a robust predictor of sociopathic penchants. The link between childhood physical abuse and MMPI–2 Psychopathic Deviate scores was examined (N = 322) as a function of birth order. A significant childhood physical abuse by birth order interaction was found (p < .0001, η² = .62) with a 6-fold increase in relative risk of a Psychopathic Deviate elevation (T > 70) found for firstborn participants. Childhood physical abuse predicted Psychopathic Deviate scores for firstborn (r = .50, p < .0001, d = 1.15) and middle-born (r = .24, p = .006, d = .49) offspring. Harris–Lingoes subscale scores suggested firstborns felt selectively alienated from self and others in response to childhood physical abuse experiences.     

Friend or foe? Postdivorce hostility among recently divorced individuals

High levels of hostility often occur during and postdivorce and may significantly affect the quality of life, parent–child relationships, and social functioning of divorcees. Moreover, hostility may predict aggressive and violent behavior. This study sought to (a) compare average general hostility levels of a large sample of Danish divorcees to the norms of the general adult Danish population, (b) compare general hostility levels between male and female divorcees, and (c) investigate the explanatory value of various sociodemographic and divorce-related factors on postdivorce general hostility and whether these factors differ across gender. Cross-sectional baseline data (N = 1,856) from a larger randomized controlled trial study was used in this study. Normative data from a general sample of Danish adults (N = 2,040) was used for comparisons of hostility levels between our study sample and the Danish background population. This study found that male and female divorcees did not report significantly different hostility levels. However, participants reported significantly higher hostility levels postdivorce than the comparative Danish norm sample. Significant predictors of postdivorce hostility were lower age, lower educational level, infidelity as a reason for divorce, higher degree of postdivorce conflict, worse communication with the former spouse, the former spouse as the initiator of the divorce, and new partner status with neither divorcees having a new partner, or only the former spouse having a new partner. The predictive strength of the factors did not differ across gender. The findings may be especially relevant for interventions targeting problematic outcomes postdivorce (e.g., preventing aggressive behavior).     

Alcohol consumption,dating relationships,and preliminary sexual outcomes in collegiate natural drinking groups

This study tested the effects of committed relationships and presence of dates on alcohol consumption and preliminary sexual outcomes in natural drinking groups (NDGs). Undergraduate drinkers (N = 302) answered an online questionnaire on their most recent participation in a NDG. The interaction between relationship commitment and presence of a date on alcohol consumption was significant. Among students not in committed relationships, those dating within their NDG reported heavier drinking than those not dating. Students in committed relationships drank less than those who were not committed only when their partners were present. The positive correlation between drinking and sexual contact was significant only for those who were not in committed relationships. Implications for future research and interventions are discussed.     

Psychometric appraisal of Eysenck's revised Psychoticism scale: a cross-cultural study

Psychometric characteristics of Eysenck's revised P scale were studied in a cross-cultural research. The Spanish version of the Eysenck Personality Questionnaire-Revised (EPQ-R) was administered to a Spanish sample of 527 males and 583 females. Maximum-likelihood factor analyses of the item intercorrelations and Direct Oblimin rotations of the extracted factors were carried out separately for males and females. The results revealed four factors identified as psychoticism (P), extraversion (E), neuroticism (N) and dissimulation/conformity (L). Internal consistency and test–retest reliability coefficients were satisfactory and very similar to the ones found in the original study. Skewness and kurtosis of the P scale distribution were closer to normal than on the original British revised P scale.
