To provide published objective factor analytic information on the Activities Index (AI), data from 1568 freshmen at Kansas State University were used in two separate factor analyses (male and female). These analyses were based on the powered vector factor analysis method. Nine orthogonal factors emerged for male and 8 orthogonal for female Ss. Fairly large amounts of total common variance were accounted for by both analyses (63.5% for males and 56.9% for females). About half of Stern's factors (1963) reappeared in this study.
