Administered the Eysenck Personality Inventory as part of a larger battery of tests to chronic users of drugs (N=43) to determine how drug use influences personality. Results showed that cocaine and opiates users were more introverted; and amphetamine users, barbiturates users and nonusers were more extraverted. (LLL)

This study investigated the correlation between the extraversion-introversion dimension and the need for, or avoidance of, sensory stimulation. (Author/RK)

Examined whether a procedure based on item response theory (IRT) for assessing the scalability of response patterns could detect deliberate dissimulation (faking good) on scores from three tests of the Eysenck Personality Questionnaire Revised. Results for 489 and 140 undergraduates show that IRT measures were not powerful enough to detect…

College freshmen (N=80) who scored near the mean on the Extraversion (E) and Neuroticism (N) scales of the Eysenck Personality Inventory were given falsified score reports. The findings are considered in terms of social desirability and reaction to stereotypical female sex roles. (Author)

Considers the cross-cultural consistency of personality inventories, concluding that it is justifiable to use the scale of the Eysenck Personality Questionnaire for comparisons within and between different countries. (Author/LHW)

E. Roskam's (1985) conjecture that steeper item characteristic curve (ICC) "a" parameters (slopes) (and higher item total correlations in classical test theory) would be found with more concretely worded test items was tested with results from 925 young adults on the Eysenck Personality Questionnaire (H. Eysenck and S. Eysenck, 1975).…

A large sample of students completed Form A of the Eysenck Personality Inventory, and four subgroups were later asked to simulate extraversion, introversion, neuroticism or stability. It was found that subjects could simulate these four personalities successfully. The changes in individual item responses were correlated with the items' factor…

A serial-reaction task was used to study personality, as well as physiological, correlates of individual differences in performance decrement under low task-load conditions. (Editor)

The construct validity of the Impulsive scale of the Interpersonal Style Inventory (ISI), and its relation to Eysenck's extraversion were investigated. High school males completed self report personality measures. They were rated by counselors on an impulsive scale. Counselor ratings correlated at a significant level with self-report scores.…

These findings are discussed in the light of earlier findings with the PEPI and some tentative explanations for the observed national differences are suggested. (Authors)

This article reports a number of findings resulting from the use of the Eysenck Personality Inventory (EPI) and a shortened form of the Leary Interpersonal Adjective Check List in the initial assessment of 100 excessive drinkers and their wives and of the readministration of the EPI 12 months later. (Author)

This study investigated three questions: the relationship between the use of stated instructional objectives and achievement in audio-tutorial (A-T) instruction, the relationship of learner personality and achievement under conditions of A-T, as well as determining the power of selected batteries of intellective and personality variables to…

The Eysenck Personality Questionnaire (EPQ) and the Sensation-Seeking Scale were administered to 219 American undergraduates and 879 English twins. Sensation-seeking was positively correlated to EPQ-measured traits of extraversion and psychoticism. There was no relationship between sensation-seeking and the trait dimension of neuroticism.…

This article reviews the Eysenck Personality Questionnaire-Revised (EPQ-R adult and EPQ-R short form), the 16PF5, and the Myers-Briggs Type Indicator for use with adults with visual impairments. Results found only the EPQ-R short form can be used by participants using low vision aids, closed-circuit television, or an optical character reader.…

Eysenck's model of personality maintains that personality differences can be expressed in terms of neuroticism, extraversion, and psychoticism. A sample of 298 female undergraduates in Israel demonstrated that a more positive attitude towards computers was associated with higher scores on psychoticism (impersonality) and lower scores on…
