  • The Short-Form Revised Eysenck Personality Questionnaire (EPQR-S): A German edition
    Social Behavior and Personality: an international journal, 2006
    Co-Authors: Leslie J. Francis, Christopher Alan Lewis, Hans-georg Ziebertz
    Abstract:

    A sample of 331 undergraduate students in Germany completed the German translation of the short form Revised Eysenck Personality Questionnaire (EPQR-S; Eysenck, Eysenck, & Barrett,1985). The findings support the psychometric properties of the extraversion, neuroticism and lie scales. The psychoticism scale, however, was found to be less satisfactory.

  • the general health Questionnaire and Eysenck s three dimensional model of Personality
    Psychological Reports, 2005
    Co-Authors: Leslie J. Francis, Mandy Robbins, Catherine F Quigley, Christopher Alan Lewis
    Abstract:

    A sample of 115 men and women between the ages of 20 and 60 completed the 30-item General Health Questionnaire together with the short-form Revised Eysenck Personality Questionnaire. The data indicate psychological distress so assessed is correlated .43 (p <.001) with Neuroticism and -.26 (p <.01) with Introversion but is unrelated to Psychoticism scores.

  • confirmatory factor analysis of the french translation of the abbreviated form of the revised Eysenck Personality Questionnaire epqr a
    European Journal of Psychological Assessment, 2002
    Co-Authors: Christopher Alan Lewis, Leslie J. Francis, Mark Shevlin, S Forrest
    Abstract:

    Summary: There is increasing interest in the abbreviated form of the Revised Eysenck Personality Questionnaire Revised (EPQR-A) as a research tool for psychologists. The present study evaluates the psychometric properties of a French translation of the EPQR-A in order to facilitate its use among French researchers. Data from a sample of French undergraduate university students were used. The dimensionality of the EPQR-A was examined in terms of the underlying latent factors. Using confirmatory factor analysis, we found evidence for the unidimensionality of the four EPQR-A subscales of extraversion, neuroticism, psychoticism, and the lie scale. These results are consistent with those of previous research with the original English version of the EPQR-A (Francis, Brown, & Philipchalk, 1992; Forrest, Lewis, & Shevlin, 2000). It is concluded that the French translation of the EPQR-A can be recommended for further use.

  • examining the factor structure and differential functioning of the Eysenck Personality Questionnaire revised abbreviated
    Personality and Individual Differences, 2000
    Co-Authors: S Forrest, Christopher Alan Lewis, Mark Shevlin
    Abstract:

    The aim of this study was to examine the psychometric properties of the Eysenck Personality Questionnaire Revised - Abbreviated (EPQR-A). Francis, Brown, and Philipchalk [Francis, L. J., Brown, L. B., & Philipchalk, R. (1992). The development of an abbreviated form of the Revised Eysenck Personality Questionnaire (EPQR-A): its use among students in England, Canada, the USA and Australia. Personality and Individual Differences, 13, 443-449] have presented preliminary data on the reliability of the EPQR-A, however the factor structure has not been evaluated using factor analytic procedures. Also, previous work by Francis I:Francis, L. J. (1993). The dual nature of the Eysenckian neuroticism scales: a question of sex differences. Personality and Individual Differences, 15, 43-59] with various forms of the Eysenck Personality Questionnaire found significant gender effects on the Neuroticism subscale, however the methodology employed was limited. The present study extends this previous work through the use of structural equation modelling procedures to examine the dimensionality of the EPQR-A in terms of the underlying latent factors and to provide information regarding gender bias at both a latent factor and individual item level. Data from 383 Northern Irish undergraduate university students were examined. Using confirmatory factor analysis, evidence was found for the unidimensionality of the four EPQR-A subscales of Extraversion, Neuroticism, Psychoticism and the Lie Scale. In addition, consistent with previous research findings significant gender effects were found on the Neuroticism, Psychoticism and Lie factors. Males were significantly higher in terms of the Psychoticism factor, and females significantly higher on the Neuroticism and Lie factors. The results are discussed and the implications considered in terms of the benefits of using structural

  • psychological status of volunteers in a phase i clinical trial assessed by symptom checklist 90 scl 90 and Eysenck Personality Questionnaire epq
    Medical Science Monitor, 2018
    Co-Authors: Yudong Wei, Huali Wang, Shuang Zhang, Yumei Sun
    Abstract:

    BACKGROUND The psychological status of volunteers was investigated to provide a theoretical method for Phase I clinical trial management and result analysis. MATERIAL AND METHODS The Symptom Checklist 90 (SCL-90) and Eysenck Personality Questionnaire (EPQ) were used to assess the psychological status 200 healthy Chinese volunteers. RESULTS SCL-90 results indicate that the average value of positive factors is 10.32±14.26 by self-assessment of healthy volunteers, somatization factor is 1.13±0.13, compulsive symptom factor is 1.29±0.27, interpersonal sensitivity factor is 1.31±0.21, depression factor is 1.26±0.33, anxiety factor is 1.21±0.21, hostility factor is 1.08±0.26, phobia factor is 1.05±0.18, paranoid factor is 1.12±0.23, and psychotic symptom factor is 1.17±0.26. CONCLUSIONS Compared to the norm in China, the score of each factor of healthy volunteers was relatively low, with a statistically significant difference (P<0.001). EPQ results show that P score was 4.59±2.33, E score is 13.13±4.32, N score was 6.89±5.26, and L score was 13.21±4.25 for the 200 healthy volunteers. Compared to the norm in China, the P and N scores were lower, and the E and L scores were higher, with a statistically significant difference (P<0.001).

    Abstract:

    Psychological health of Chinese healthy volunteers was investigated to provide a theoretical method for phase I clinical trial management and result analysis. Symptom checklist 90 (SCL-90) and Eysenck Personality Questionnaire (EPQ) were used to assess 200 healthy volunteers and to analyse the level of psychological health of Chinese healthy volunteers. SCL-90 result indicates that the average value of positive factors is 10.32 ± 14.26 by self-assessment of healthy volunteers, somatization factor is 1.13 ± 0.13, compulsive symptom factor is 1.29 ± 0.27, interpersonal sensitivity factor is 1.31 ± 0.21, depression factor is 1.26 ± 0.33, anxiety factor is 1.21 ± 0.21, hostility factor is 1.08 ± 0.26, phobia factor is 1.05 ± 0.18, paranoid factor is 1.12 ± 0.23, psychotic symptom factor is 1.17 ± 0.26. Comparing the norm in China, the score of each factor of healthy volunteers is relatively low with statistically significant difference (P<0.001). EPQ result shows that P score is 4.59 ± 2.33, E score is 13.13 ± 4.32, N score is 6.89 ± 5.26, and L score is 13.21 ± 4.25 for 200 healthy volunteers. Comparing the norm in China, the P and N scores are lower, and the E and L scores are higher, with statistically significant difference (P<0.001).

  • Genetic and environmental variation in Eysenck Personality Questionnaire scales measured on Australian adolescent twins
    Behavior Genetics, 1994
    Co-Authors: Greg T. Macaskill, John L. Hopper, Victoria White, David J. Hill
    Abstract:

    The Eysenck Personality Questionnaire was administered to 1400 Australian twin pairs aged 11 to 18, and the data were analyzed by a multivariate normal model using the software FISHER. For each scale, attempts were made to transform to normality, about a mean modeled separately for each sex as a quadratic function of age. Variances and covariances were estimated for each sex-zygosity group as a monotone function of age. Evidence for genetic sources of variation were assessed in part by fitting models which allowed for age-dependent, sex-specific, and correlated additive genetic factors, and age-dependent and sex-specific environmental factors, under the assumption that effects of environmental factors common to twin pairs are independent of zygosity. Evidence for genetic factors independent of age and sex was most compelling for Psychoticism and Neuroticism. For Extraversion, if genetic factors exist they would be mostly sex-specific and age-dependent. For the Lie scale there was evidence for, at most, a small component of genetic variation.

  • Alcohol use, smoking habits and the Junior Eysenck Personality Questionnaire in adolescent Australian twins
    Acta geneticae medicae et gemellologiae, 1992
    Co-Authors: John L. Hopper, Victoria White, Greg T. Macaskill, David J. Hill, Ca Clifford
    Abstract:

    In 1988, Questionnaires were received from 1,400 twin pairs (17% MZM, 23% MZF, 17% DZM, 19% DZF, 24% DZO) aged 11 to 18, registered with the Australian NHMRC Twin Registry. Twins reported independently on themselves and on the perceived behaviour of their parents, siblings and friends. For smoking and for drinking in the previous month, the prevalence was modelled as a logistic function of age, sex, perceived smoking or drinking behaviour of family and friends, and the Adult Eysenck Personality Questionnaire (AEPQ) scales. Strengths of association were: family behaviour, odds ratio (OR) Language: en
