Abstract
Autonomy and sociotropy, reflecting excessive concern about autonomous achievement and interpersonal relationships, respectively, have been proposed as the two personality dimensions that prompt vulnerability to depression. Accordingly, several self-report questionnaires have been developed to measure these two dimensions. The revised Personal Style Inventory (PSI) represents a significant improvement over existing measures in that it assesses entire domains of autonomy and sociotropy. However, the PSI’s usefulness has been undermined by its unclear factor structure. Using 574 college students in Korea, the present study examined the factor structure of the revised PSI using hierarchical confirmatory factor analysis. Several first-order and two two-factor hierarchical models were tested, with a hierarchical model specifying perfectionism as associated with both hierarchical factors (Autonomy and Sociotropy) deemed the best fitting.
