Religiosity and the short-scale EPQ-R indices of E,N and L,compared with the JEPI,JEPQ and EPQ

The short-scale EPQ-R proposes 12 item indices of E, N and L. The reliability and validity of these short indices and their relationship with religiosity are explored among 181 15- and 16-yr olds in comparison with the longer scales of the EPQ, JEPQ and JEPI. The value of the short-scale EPQ-R is recommended for further research.     

The Narcissistic Personality Inventory: alternative form reliability and further evidence of construct validity

The aim of this study was twofold: (a)to measure the alternate form reliability of the Narcissistic Personality Inventory, and (b)to determine its construct validity by correlating it with the four scales of the Eysenck Personality Questionnaire (EPQ). The alternate form reliability was .72. The Extraversion and Psychoticism scales of the EPQ were positively and significantly correlated with the narcissism measure, and the Lie scale showed a significant negative correlation. The Neuroticism scale showed a nonsignificant relationship with narcissism. In addition, the combined Extraversion and Psychoticism scales produced[ a Multiple R with the narcissism measure that accounted for significantly more of the variance in narcissism than did either measure alone.     

Self-conscious emotions and criminal offending

This study examined the relation of personality traits--shame-proneness, guilt-proneness, and pride--on offending behavior. Using survey data from a sample of 224 college students, the construct and criterion-related validity of scales of the Shame Proneness Scale, the Test of Self-conscious Affect, and the Personality Feelings Questionnaire-2 were assessed. Regression analyses showed that self-conscious emotions are important in the etiology of criminal offending. Specifically, rated pride was positively correlated with self-reported criminal activity, whereas ratings of guilt were negatively associated with offending. The relation of shame with criminality varied depending on the type of measure used to indicate proneness to shame.     

Construct validity and personality correlates of the Strelau temperament inventory

Strelau's reinterpretation of Pavlov's concept of nervous system properties has gained increasing attention in Western personality research, both with regard to the psychometric properties of the Strelau Temperament Inventory (STI) and with regard to the interrelations between STI and Western personality dimensions. The present study investigated the construct validity of the Strength of Excitation scale by examining its relationship to experimental indices of strength of the nervous system. Secondly, data on the convergence between STI, EPQ, SSS IV, and trait anxiety measures are presented, using German translations of all the questionnaires. The results confirmed the correlation between strength of excitation and a reaction time based measure of strength of the nervous system. A factor analysis on the questionnaire scales identified two factors. Factor I (activity/stimulation seeking) consisted of extroversion, mobility, strength of excitation and the sensation seeking scales whereas Factor II (instability vs control) was composed of anxiety/neuroticism/ psychoticism and strength of excitation/strength of inhibition/social desirability. These findings agree with Eysenck's and Strelau's theoretical predictions regarding the interrelations of Pavlovian properties and Western personality dimensions.     

Notes and shorter communications: Psychoticism and unemployment

The Eysenck Personality Questionnaire (EPQ) was given to male skilled and semi-skilled workers facing redundancy, in an attempt to ascertain whether any of the factors measured contributed towards a predispositional tendency for unemployment. Psychoticism was found to be a sound predictor of future work status for the school group, whilst no differences of merit were noted for any variable for the redundant group. The results are discussed in relation to other findings with regard to EPQ trait factors, and in particular to Psychoticism.     

The factor structure of the Eysenck Personality Profiler in Russia

One hundred and seventy seven males and 399 females completed a translated short version of the Eysenck Personality Profiler (EPP-S). Two hundred and ninety four Ss also completed the EPQ. By means of item analysis, further shortening of the EPP was achieved, while retaining adequate psychometric characteristics and convergent validity with EPQ scales. Confirmatory factor analysis (CFA) confirmed the Eysenck hierarchical model of personality with three basic dimensions and showed stability of the EPP factor structure across genders and sub-samples of different origin. However, CFA showed that only E and P were independent, while N was correlated with E and P.     

Examining risk of escalation: A critical review of the exhibitionistic behavior literature

While forensic mental health professionals frequently are asked to assess the risk that exhibitionistic offenders will increase the severity of their sexual offending, disparate perspectives exist reflecting the perceived dangerousness of those who engage in exhibitionistic behavior. The present paper critically reviews the literature regarding the reported link between male exhibitionistic behavior and contact sexual offending in 12 peer-reviewed, English-language studies published since 1981. A history of exhibitionistic behavior was prevalent in a minority of perpetrators of various contact sexual offenses. Over an average follow-up period of greater than five years, an estimated 5–10% of exhibitionistic perpetrators were found to escalate to contact sexual offending, while approximately 25% recidivated with a subsequent exhibitionistic offense. The most supported risk factor for escalation was a general clustering of antisocial behavior, including a history of sexual and nonsexual convictions. Common methodological limitations of the research and recommendations for improved validity are provided, along with suggestions for future research directions.     

Factorial and Construct Validity of FACES IV Among Italian Adolescents

The aims of this study were to evaluate the reliability, validity and factorial structure of Family Adaptability and Cohesion Evaluation Scale, Version IV (FACES IV), investigate the relevance of sex and age on family functioning and study the relationship between family functioning and adolescents’ perception of parent and peer attachment. The sample consisted of 1,416 participants (672 women, 744 men, M_age = 17.38 years; age range = 13–22 years) divided into three age groups: 13–15, 16–18, and 19–22 years. Factor analysis confirmed the dimensions formulated to define the construct of family functioning: all the items of each dimension were loaded in the same factor with a correlation of at least 0.30. Groups differed with regard to the age on Cohesion, Enmeshed and Rigid scales: Younger adolescents (age 13–15 years) showed significantly higher scores than adolescents (age 16–18 and 19–22). Sex differences revealed that females had a higher mean score on Cohesion and Flexibility, whereas males had a higher mean score on Disengaged, Enmeshed and Chaotic. Correlations between FACES IV and Parent and Peer Attachment Scale demonstrated the convergent validity of the FACES IV. Data confirmed the validity of FACES IV’s Italian version and suggested that the Circumplex Model has a cross-cultural applicability and it could be a useful instrument in the Italian context.     

Assertiveness,aggressiveness and Eysenck's personality variables

The relationship of scores on the Interpersonal Behavior Survey (IBS) and the Eysenck Personality Questionnaire (EPQ) were studied to investigate the relationship of assertiveness and aggressiveness to more basic dimensions of personality. This relationship was studied in two samples. Sample one consisted of 12 psychiatric inpatients, 67 college students and 69 state prison inmates. Sample two was made up of 50 psychiatric inpatients. The correlational results were highly similar in both samples. Significant negative correlations were found between the EPQ Neuroticism scale and IBS assertiveness scales; significant positive correlations were found between the EPQ Neuroticism and Psychoticism scales and the IBS aggressiveness scales, and significant positive correlations were obtained between the EPQ Extraversion scale and the IBS assertiveness scale. An ANOVA revealed a significant Neuroticism by Extraversion interaction on the IBS General Assertiveness, Rational scale. Neurotic introverts were found to have especially large deficits in assertive behavior. The results are generally consistent with Eysenck's theory of personality.     

The comparability of the JEPI, JEPQ and EPQ among 15- to 16-yr olds

One hundred and ninety-one 15- to 16-yr olds completed the Junior Eysenck Personality Inventory (JEPI), the Junior Eysenck Personality Questionnaire (JEPQ) and the Eysenck Personality Questionnaire (EPQ). In terms of the internal consistency of the test items, and the statistical independence of the scales, the EPQ emerges as the most satisfactory measure of personality dimensions in this age group.     

Structural and functional equivalence of the Eysenck Personality Questionnaire within and between countries

The question was examined as to whether scores at the individual level and scores at the country level on the four scales of the Eysenck Personality Questionnaire (EPQ) have the same psychological meaning. Using data of 24 countries, it was found that the EPQ has different factorial structures at both levels. Both the Lie scale and the Psychoticism scale were shown to jeopardize cross-level equivalence. For further exploration of the meaning of the EPQ scales within countries and between countries country-level correlations were calculated with a variety of country characteristics such as Gross National Product, political indices, religiosity, Hofstede's measures, and subjective well-being. Significant findings for 38 countries included correlations of the EPQ scales with Hofstede's Masculinity, Diener's Subjective Well-Being, religiosity, the number of deaths in a country due to political violence, and bribery. The most striking finding was a substantial negative correlation of the Lie scale with Gross National Product and other wealth-related indices.     

The Formal Characteristics of Behaviour—Temperament Inventory (FCB—TI): Validity studies

A psychometric study has been conducted with the aim of testing the validity of the Formal Characteristics of Behaviour—Temperament Inventory (FCB—TI). FCB—TI has been constructed to measure six temperament traits according to the Regulative Theory of Temperament (RTT): Briskness, Perseverance (referring to the temporal aspect of behavior), Sensory Sensitivity, Emotional Reactivity, Endurance, and Activity (referring to the energetic characteristics of behaviour). These traits have been compared with other temperament as well as personality dimensions. The following measures were used: PTS, EAS—TS, DOTS—R, EPQ—R, SSS—V, 16PF, and NEO-FFI. The study was conducted on samples consisting of over 1500 subjects with satisfactory balanced gender ratio (about 50 per cent), and with a broad range of age (from 15 to 77 years), representing a variety of professions and educational levels. The correlational and factor analytic findings are presented; these show high theoretical validity of the FCB—TI scales, except the Sensory Sensitivity scale. In the discussion some conclusions concerning the revision of the structure of temperament have been suggested.     

Effects of Augmenting Response Options on MMPI–2 RC Scale Psychometrics

A number of empirical investigations indicate that tests with a greater number of response options tend to yield better psychometric performance. We hypothesized that a version of the MMPI–2 with a polytomous response format would outperform the standard dichotomous format in terms of observed score reliability and validity. Two versions of the MMPI–2 RC scales were administered consecutively in counterbalanced order to 199 undergraduate students attending a large Midwestern university: the standard true–false version, and an experimental version containing 4 response options (very true, mainly true, slightly true, and false, not at all true). After participants completed both versions, 2 scales from the Multidimensional Personality Questionnaire (MPQ) were administered to assess differences in convergent validity. Results showed enhancements in reliability for all RC scale scores and increases in the convergent validity of scores. Directions for further investigation and potential implications for future test development are discussed.     

Two experiments on the relation between psychoticism and response uncertainty in normal subjects

Previous studies have suggested that schizophrenics are affected by response uncertainty to a greater degree than normals or other psychiatric groups. Two studies examined whether a similar pattern of performance would be produced in normal Ss scoring high on questionnaire measures presumed to measure psychotic predisposition. The Psychoticism (P) scales from the EPQ and the unpublished PEN Inventory were employed; and response uncertainty was varied using a card-sorting procedure. In Experiment 1 males were more affected by increases in response uncertainty than females, but there was no difference between Ss scoring high and low on the P scales. Experiment 2 included a condition in which guide-cards were randomly reordered between trials. There was a highly significant tendency for Ss scoring high on the PEN P scale to be more affected by response uncertainty in this experiment. Again males were more influenced by uncertainty than females, but this was due largely to their performance under the condition where guide-cards were varied. Ss high on EPQ P also showed decremental performance under this condition. The data provided partial support for the validity of the P scales, particularly the PEN version of the scale, as indices of schizophrenic predisposition.     

Dimensionality and validity of two scales measuring different aspects of self-esteem

Two self-esteem (SE) scales aimed to measure self-esteem–conceptualized primarily (a) as the individual's ego-integrated libidinous and aggressive drives and their derivatives (Basic SE), and (b) as the need to earn self-esteem by competence and others' appraisal (Earning SE)–were developed and factor analysed. In order to construct- and cross-validate the scales, they were related to other well-known personality scales as well as to a projective technique (TAT) in two independent samples of first semester psychology students ( n = 153, n = 82). The empirical factor structure coincided well with the theoretical formulations. Basic SE showed concurrent validity being highly correlated ( p < 0.001) with both Rosenberg's and Coopersmith's self-esteem scales and highly or moderately with Neuroticism, Extraversion (EPQ) and Test-Anxicty (TAS) in both samples. Earning SE gained some construct validation by its relation to Type-A scores (JAS) as well as to verbal fantasy stories on TAT-pictures measuring Need of Achievement.     

Psychometric properties of the Danish 16PF and EPQ

A Danish translation of the Cattell's 16PF has been used in studies evaluating the effects of prenatal drug exposure. This paper reports a psychometric analysis of the 16PF and Eysenck's EPQ based on a sample of 558 young Danes. Many 16PF scales had unacceptable psychometric properties (as indicated by coefficient alpha and item–total score correlations), but more satisfactory results were obtained with the EPQ N and E scales. A factor analysis of all 16PF and EPQ scales suggested a six factor solution that roughly corresponds to the second-order factor structure obtained by Krug and Johns (1986). It is concluded that the second-order factor structure should be the basis of interpretation of the 16PF in both practical and research contexts.     

Psychopathy and Anxiety in Children and Adolescents: New Insights on Developmental Pathways to Offending

This study examined the relation between psychopathy and anxiety in 130 juvenile offenders. Adolescents were administered three psychopathy scales (PCL-YV, APSD, and SRP-II), a measure of psychopathology (APS), and subsequently followed prospectively in the community for three years in order to track recidivism. Three mediational models were tested to determine whether psychopathy mediates the relation between anxiety (trait anxiety, fearlessness, and trauma) and future offending. Findings indicated that psychopathy mediated the relation between two types of anxiety (trait anxiety and fearlessness) and recidivism when using the PCL-YV as an index for psychopathy. These influences were not supported when using self-report measures of psychopathy (APSD and SRP-II) and the meditational models did not apply to the anxiety subtype of trauma for any of the psychopathy measures. The PCL-YV mediational models provide new insights on the relation between psychopathy anxiety and offending. Specifically, pathways from fearlessness to psychopathy and later offending were in the expected direction. Surprisingly, higher levels of trait anxiety were linked with higher levels of psychopathy and subsequent offending. This developmental difference is in contrast with theory and the adult literature on this topic. The results from the current study suggest that both fear and anxiety may be important considerations in treatment planning for the reduction of adolescent offending.     

The Millon Adolescent Clinical Inventory: is it valid and reliable for Mexican American youth?

In this study, we examined the internal consistency reliability, construct-related validity, and mean base rate scores of the Millon Adolescent Clinical Inventory (MACI; Millon, Millon, & Davis, 1993) Personality and Clinical scales in a sample (N = 131) of juvenile offending, educationally at-risk, and substance-dependent Mexican American youth. Overall, the MACI scales demonstrated good reliability estimates. Using methods derived from contrast analysis (Westen & Rosenthal, 2003), the scales performed as would be expected based on predictions derived from Millon's (1969, 1981) theory. In addition, the scales differentiated in an expected fashion among the 3 groups. The results of this study provide preliminary support for the use of the MACI among Mexican Americans.     

Measuring Four Perspectives of Justice Sensitivity With Two Items Each

People differ systematically in their vulnerability to injustice. We present two-item scales for the efficient measurement of justice sensitivity from 4 perspectives (victim, observer, beneficiary, perpetrator). In Study 1 using a quota-based sample of German adults, a latent state–trait analysis revealed the factorial validity and high reliabilities of the scales. In Study 2 employing a large random sample, we tested for measurement invariance of the items within the context of our short 2-item scales compared to the original 10-item scales. Multigroup confirmatory factor analyses confirmed that the validity of the indicators and the internal structure of the assessed constructs did not change across item contexts. In both studies, correlations with personality dimensions and life satisfaction provide evidence for the validity of our scales. With the presented instrument, future research can extend scientific knowledge regarding the role of individual differences in reactions to injustice for the explanation of well-being and physical health.     

Characteristics of the frequent nightmare sufferer.

Previous research has found that persons who experience frequent nightmares score highly on scales that measure psychotic symptomatology. Neurotic symptoms have also been implicated as correlates of nightmare frequency. In this study, 30 adult lifelong nightmare sufferers were compared with 30 control subjects, matched for age, sex, and socioeconomic status. Subjects were asked to record all dreams for 1 month and to complete the Minnesota Multiphasic Personality Inventory (MMPI) and the Eysenck Personality Questionnaire (EPQ). Nightmare subjects scored significantly higher on the EPQ Neuroticism scale and on 8 MMPI clinical scales than did the control group. These scales also best discriminated between the groups in a direct discriminant analysis. The results are interpreted as a reflection of global maladjustment rather than of specific psychotic symptomatology.
