Validity and Reliability of the Revised California Psychological Inventory's Vector 3 Scale

Abstract

This study examined the validity and reliability of the revised California Psychological Inventory's (CPI) Vector 3 (v.3) self-realization scale by administering it and other personality questionnaires to 528 introductory psychology students. Coefficient alpha for the v.3 scale was .85 for the entire sample, and was .84 and .86 for males and females, respectively. V.3 correlated .47 with the Inner Directed scale of the Personal Orientation Inventory, the most widely used measure of self-actualization. In addition, subjects who were more self-realized had higher self-esteem, more internal locus of control, fewer neurotic symptoms, lower trait and state anxiety, and were more assertive than those who were less self-realized. It was concluded that v.3 is a valid measure of Gough's self-realization construct.
