Abstract
A study of the relationships between the Ac, Ai, and Ie scales of the CPI and three criteria-GPA, verbal ability, and quantitative ability-was carried out with six groups of college freshmen. Each group differed from the others in one or both of the following characteristics: 1) sex and 2) enrollment in a psychology-of-adjustment course. The obtained Ac-GPA and Ie-GPA correlations were found to be nonsignificant for all groups used in the current investigation. Ai was significantly related to GPA of the total psychology-of-adjustment and the male psychology-of-adjustment groups. While all three scales were generally unrelated to quantitative ability, Ai and Ie were somewhat related to verbal ability-especially for male freshmen.
