The Junior Eysenck Personality Questionnaire: An American sample

A sample of 1838 students enrolled in public schools in Merced, CA, responded to the Junior Eysenck Personality Questionnaire (JEPQ). The students ranged in age from 7 to 15 yr and included 938 boys and 900 girls. Means and SDs for each age and sex were computed and compared to the corresponding values for the British sample presented in the manual. Differences between the two samples were small. In addition, a factor analysis of the item responses was conducted for the American sample. This analysis produced four factors closely corresponding to the scales on the JEPQ. This study along with previous literature indicate that the JEPQ is appropriate for use in the United States.
