The Junior Eysenck Personality Inventory ratings of traumatized youth with and without PTSD

The Junior Eysenck Personality Inventory (JEPI) scores of traumatized youth with or without PTSD were compared to the scores of a non-traumatized control group. It was observed that the PTSD group had significantly higher JEPI Neuroticism scores relative to the comparison groups. The JEPI Neuroticism scores of the traumatized group without PTSD and the non-traumatized controls were not significantly different. Nonsignificant differences were also evidenced between groups on the JEPI Extraversion and Lie scales.

CHRISTIANITY AND DOGMATISM REVISITED: A STUDY AMONG FIFTEEN AND SIXTEEN YEAR OLDS IN THE UNITED KINGDOM

A sample of 802 adolescents between the ages of fifteen and sixteen years completed an Anglicized form of the Dommert revision of the Rokeach Dogmatism Scale and the Francis Scale of Attitude toward Christianity, together with the Junior Eysenck Personality Inventory. The data demonstrate that attitude toward Christianity and dogmatism are unrelated constructs, although both are related, in different ways, to Eysenck's major dimensions of personality.

The validity of the children's PTSD inventory

AbstractThe Children's PTSD Inventory (CPTSDI) was administered to 76 traumatized and 28 nontraumatized youths. CPTSDI diagnoses were compared to DICA‐R and SCID PTSD diagnoses. Moderate to high sensitivity, specificity, positive and negative predictive power, and diagnostic efficiency were evidenced across criterion measures. Convergent validity was evidenced by significant correlations with the Revised Children's Manifest Anxiety Scale, Children's Depression Inventory, Child Behavior Checklist (CBCL) Internalizing scale, and the Junior Eysenck Personality Inventory (JEPI) Neuroticism scale. Discriminant validity was observed through nonsignificant correlations with the CBCL Externalizing and the JEPI Extroversion scales.

Extraversion: Interaction between D2 dopamine receptor polymorphisms and parental alcoholism

Both molecular genetic factors (the D2 dopamine receptor (DRD2) and the D4 dopamine receptor (DRD4) polymorphisms) and environmental influences of living in an alcoholic or nonalcoholic home on the personality traits of Extraversion and Neuroticism were assessed in drug-naive, young adolescent boys. There were no significant main effects of genetic or environmental factors on either Neuroticism or Extraversion as measured by the Junior Eysenck Personality Inventory (JEPI). However, a significant interaction between DRD2 (but not DRD4) alleles and environmental variables was observed on Extraversion. Specifically, children with the minor alleles of the DRD2 gene showed a significantly greater Extraversion score when living in an alcoholic than in a nonalcoholic home. In contrast, children with the major alleles of the DRD2 gene showed a trend in the opposite direction. Although the results are preliminary and pending replication, they nevertheless provide the first report of a specific gene–environment interaction involving a human personality trait.

Neuroticism and Sleep-related Problems in Adolescence

To examine the relationship between neurotic personality characteristics and sleep habits/problems. A population-based cross-sectional study. NA. Nine hundred sixty five students from two junior high schools in Taipei and their parents were randomly selected in December 1993 for inclusion in the study. The response rate was 96.4% (930) for students and 88.6% (855) for parents. NA. Students were administered a sleep habit questionnaire and the Junior Eysenck Personality Inventory (JEPI) at both junior high schools in Taipei. For the JEPI, high and low neuroticism was operationally defined as scores that were one or more standard deviation above or below the sample mean, respectively. This yielded two extreme groups: high neuroticism group (n=183) and low neuroticism group (n=163). The high neuroticism group went to bed later and slept less than did the low neuroticism group. Using logistic regression, adjusting for sex and years at junior high school, the high neuroticism group had significantly different sleep habits and school performance from the low neuroticism group. Subjects in the high neuroticism group had significant risk of feelings of sleep insufficiency, tiredness, moodiness, and difficulty waking up in the morning; they also had more daytime sleepiness than did those in the low neuroticism group. The high neuroticism group also suffered from more sleep-related problems than did the low neuroticism group. The findings support the hypothesis that a high neuroticism score is associated with going to bed late on school days, short sleep duration, different sleep habits, sleep problems, and impaired daytime function in comparison with a low neuroticism score.

Psychiatric comorbidity of adolescents with sleep terrors or sleepwalking: a case-control study.

This study investigated the psychiatric comorbidity, personality traits and family history of adolescents with sleep terrors and/or sleepwalking. Thirty students with sleep terrors and/or sleepwalking and 30 classroom controls were selected on the basis of a sleep habit questionnaire. After completing the Junior Eysenck Personality Inventory (JEPI), the 60 subjects were interviewed by the first author with the Chinese-version Kiddie-SADS-E (Schedule for Affective Disorders and Schizophrenia for Children--Epidemiology Version). All subjects and their parents were interviewed for the subjects' sleep habits, sleep disorders, and personality characteristics in the previous year. The case and the control groups were divided based on whether the sleep terrors and/or sleepwalking had occurred in the previous year. There were 21 case and 30 control subjects in the final data analysis. The case group had more psychiatric diagnoses and problems; there were statistically significant differences in overanxious disorder, panic disorder, simple phobia and suicidal thoughts between the two groups. The case group had more sleeptalking and nightmares during the previous year as well as more enuresis in earlier years. From their parents' perspective, the case group was more nervous and pessimistic. The results of the JEPI showed a high neuroticism score in the case group. There was an increased familial occurrence of these two sleep disorders. Adolescents with sleep terrors and sleepwalking were found to have an increased prevalence of other sleep disorders, neurotic traits, and psychiatric disorders and problems. Whereas sleep terrors and sleepwalking in childhood are related primarily to genetic and developmental factors, their persistence and, especially, their onset in adolescence may be related to psychological factors.

Dogmatism and Eysenck's two-dimensional model of personality revisited

A sample of 802 year eleven pupils completed the Junior Eysenck Personality Inventory together with Dommert's modification of the Rokeach Dogmatism Scale. The data confirm the view that neuroticism is the dimension of personality fundamental to individual differences in dogmatism, while extraversion is irrelevant to dogmatism.

Personal and Social Correlates of the ‘Closed Mind’ among 16 Year Old Adolescents in England

Summary A sample of 711 16 year old adolescents completed an Anglicised form of the Dommert revision of the Rokeach Dogmatism Scale, together with the Junior Eysenck Personality Inventory and Raven's Standard Progressive Matrices. They also provided information about church attendance, personal prayer and paternal occupation. The data demonstrate that higher dogmatism scores are associated with lower IQ scores, lower social class backgrounds, higher neuroticism scores, higher lie scale scores and being male. No correlation was found between dogmatism scores and personal prayer, church attendance or extroversion scores. These findings are discussed against the wider background of the personal and social correlates of dogmatism.

The relationship between Rosenberg's construct of self-esteem and Eysenck's two-dimensional model of personality

The Rosenberg Self-Esteem Scale was completed by 802 year-eleven secondary school pupils, together with Neuroticism, Extraversion and Lie Scales of the Junior Eysenck Personality Inventory. The data demonstrate that good self-esteem was associated with Extraversion, Emotional Stability and with being male.

The properties of the lipsitt self-concept scale in relationship to sex, social desirability, neuroticism and extra version

The Lipsitt Self-Concept Scale was completed by 802 16-yr olds, together with the neuroticism, extraversion and Lie scales of the Junior Eysenck Personality Inventory. The overall reliability of the instrument is supported among this age group. Regarding the construct validity of the instrument, the data demonstrate that Lipsitt's implicit assumptions regarding the nature of a good self-concept favour femininity, social conformity, extraversion and emotional stability.

Physiological and Cognitive Correlates of Child Abuse

To compare the physiological responses of abused children to different stimuli with responses of children in a reference group and to correlate the physiological responses with intellectual and personality functioning. Abused children were compared with a reference group on two batteries of tests that were administered on separate days. In one session, children were shown slides with emotional or cognitive content while heart rate, pulse height, skin conductance, electromyography, and skin temperature were measured. In the other session, intellectual and personality functioning was measured using the WISC-R, Quick Neurological Screening Test, and the Junior Eysenck personality inventory. Abused children had smaller changes in pulse height in the first two stimulus conditions presented ("No Signal" and "Math"), but their electrodermal responses were lower throughout all stimulus conditions. Abused children also had higher introversion and lower Verbal and Full Scale IQ scores. Verbal and Full Scale IQ scores were inversely related to the severity of abuse that had been experienced. When these variables were used in a discriminant function analysis, children were assigned to the correct group 86% of the time. These findings support a model that describes the effects of abuse as delaying cognitive development and inhibiting physiological responsiveness to the environment.

The relationship of Eysenck's personality factors and self-esteem to bully-victim behaviour in Australian schoolboys

In the present study we examined the relevance of selected personality variables, namely Eysenck's factors of extraversion, psychoticism and neuroticism, and the psychological well being factor of self-esteem to the tendency to bully and to be victimized. Male primary school children ( n = 87) with a mean age of 10.9 years completed the Junior Eysenck Personality Inventory and the Coopersmith Self Esteem Inventory. Children's tendency to bully and to be victimized was assessed by means of questionnaire and teacher nomination. As predicted the tendency to bully was found to be significantly associated with psychoticism while the tendency to be victimized was significantly associated with introversion and low self-esteem. The expected association between being victimized and neuroticism was not confirmed.

Personality characteristics of alcoholic fathers and their sons.

Recovering alcoholic fathers with a positive family history of alcoholism and their 10-15 year-old sons were assessed on a variety of personality measures and compared to a matched group of nonalcoholic fathers with a negative family history of alcoholism, and their sons. Assessment instruments for the sons included the Personality Inventory for Children, High School Personality Questionnaire, Junior Eysenck Personality Inventory and the Tridimensional Personality Questionnaire. Comparable questionnaires were administered to the fathers: the MMPI, 16 Personality Factor Questionnaire, Eysenck Personality Inventory and the Tridimensional Personality Questionnaire. No psychopathology or extreme personality variants were observed in either fathers' or sons' groups. However, MANOVAS and linear discriminant functions revealed significant differences on several personality measures between fathers' and sons' groups. Compared to sons of nonalcoholics, sons of alcoholics were relatively more compulsive, insecure and fearful while being more subdued and detached. The recovering alcoholics were more impulsive and regimented than the nonalcoholics. An index resulting from the combination of the best personality discriminators was significantly correlated in father-son pairs. In addition, this index was significantly correlated with key neurocognitive variables from our previous study which assessed the same father-son pairs. This atypical CNS profile, encompassing altered electrophysiology, neuropsychological performance and personality traits, may be useful in identifying those at increased risk for developing alcoholism.

Autonomic Nervous System (ANS) Activity, Personality Characteristics and Disruptive Behaviour in Girls

Disruptive behaviour in school, as defined by teachers, was examined in 44 unselected girls, aged 12-13 years, attending two private schools. Except for the psychoticism (P) scale of the Junior Eysenck Personality Inventory (JEPI), such conduct did not appear to be related to the personality characteristics as measured by the JEPI. Autonomic nervous system activity, indexed here by heart rate measures, successfully discriminated between the three behaviourally defined groups. The findings, with data derived from girls, largely confirm earlier exploratory studies with adolescent boys, and have implications for further research and current approaches to management.

Sex and personality differences in French and German performance in British secondary school pupils

An experiment was performed to investigate the relationship between sex, personality and learning style and French and German performance in secondary school pupils. 432 13–14 year old children (216 boys and 216 girls) whose mother tongue was English were given the Junior Eysenck Personality Inventory and Raven's Standard Matrices. Half of the subjects were then given three performance tests (comprehension, essay and prose translation), and the rest received three parallel German tests. The main findings were that, although pupils studied each language for the same time, German was easier than French, girls did better than boys, and that language performance increased with extraversion. The results were discussed in terms of their practical implications.

‘Faking good’ with self-reported pro-authority attitudes and behaviours among schoolchildren

This study examined the relationship between the L Scale measure of social desirability responding on the Junior Eysenck Personality Inventory and two types of measures of self-reported pro-authority tendencies among schoolchildren. One type of measure assessed attitudes and the other behaviour, each in relation to the authority of parents and teachers. Positive and, in most cases, significant correlations were found between the L Scale and both types of measures. However, as predicted, correlations with the self-reported behaviour scales were, in general, significantly higher, suggesting that attitude to authority scales are less susceptible to bias resulting from ‘faking good’.

Sex and Personality Differences in Performance on Number Computation in 11‐year‐old Children

Abstract Eighty‐four eleven‐year‐old children were grouped in three levels of extraversion on the basis of their score on the Junior Eysenck Personality Inventory (JEPI). They were then given a test of number computation consisting of addition, subtraction, multiplication and division at two levels of difficulty. A significant interaction between extraversion, sex and type of operation was found such that for girls extraverts and introverts were superior to ambiverts, and the difference was greater for multiplication and division than for addition and subtraction. In the case of boys the pattern was reversed with ambiverts doing better than extraverts and introverts. The results were discussed in terms of learning style and sex differences in information processing.

SEX AND PERSONALITY DIFFERENCES IN SECOND LANGUAGE PERFORMANCE IN SECONDARY SCHOOL PUPILS

Summary. Two experiments investigated the relationship between sex and personality and second language performance in secondary school pupils. In the first, 56 13–14‐year‐old children were given the Junior Eysenck Personality Inventory, Raven's Standard Matrices and three French performance tests (comprehension, essay and prose translation). Two significant effects were found: (a) The performance of girls was superior to boys; (b) there was an interaction between Raven's matrices, extraversion and test type such that for extraverts, high Raven's subjects were superior to low Raven's on the essay and translation tasks which required a large amount of translation from English to French, but not on comprehension, while for introverts the pattern was reversed. In the second experiment 48 12–13‐year‐old children were given the Junior Eysenck Personality Inventory, Raven's Standard Matrices and two French performance tests (comprehension and essay) which were both scored according to ability to use singular and plural, set phrases and verbs. Again girls were superior to boys. There was also a significant interaction between Ravens, extraversion and skill type.

Personality and functional hearing loss in children.

Thirty children with functional hearing loss were seen for psychological assessment. The sample included twice as many girls as boys. Most had experienced middle-ear problems and scored outside normal limits on the Junior Eysenck Personality Inventory. Introversion alone or combined with neuroticism was the most important personality dimension, especially for girls. The relationship between introverted behaviour, hearing impairment and previous experience of hearing problems is discussed.
