A comparison of the Eysenck Personality Questionnaire and the Psychological Screening Inventory in a delinquent sample and a comparison group.
Administered the Eysenck Personality Questionnaire (EPQ) and Psychological Screening Inventory (PSI) to a group of technical college students (N = 100) who were taking trade training courses. The groups were similar in terms of age and socioeconomic status. A factorial analysis was performed on both of the resulting sets of intercorrelations, and two factors were found to account for over 85% of the variance in each group. The first factor was common to both groups and was labelled neuroticism. While the second factor in the delinquent group clearly could be seen to be extraversion, the second factor in the student group was not interpreted easily, but appeared to be a dimension that represented psychiatric and antisocial problems.
