Detectability of Items and Self-Rating Validation of the Eysenck Personality Inventory

Summary

Sixty-seven men and women selected as representative of the community of Regina attempted to identify which items of the EPI were measures of E, N, and L. In contradiction to previous findings employing university students, the present sample was neither cognizant of the EPI's specific objectives nor were they capable of detecting accurately individual items with any degree of consistency. In addition, Ss were requested to rate themselves on E and N. Self-rating and EPI means and standard deviations were essentially equivalent. Correlations between self-rating and EPI measures of E and N were 0.57 and 0.41, respectively.
