A factor analysis of the California Psychological Inventory

Abstract

Using test scores from 372 Ss, various statistical analyses indicated that a reduced set of 6 scales accounts for about ⅔ of the total variance in the CPI. "… the reference scales provide more concise and less ambiguous definitions of the variables assessed by the CPI and have considerable promise as measures of the normal personality."
