DO INTERPERSONAL AND ACHIEVEMENT VULNERABILITIES INTERACT WITH CONGRUENT EVENTS TO PREDICT DEPRESSION - COMPARISON OF DEQ, SAS, DAS, AND COMBINED SCALES

Interpersonal but not achievement scales of the Depressive Experiences Questionnaire (DEQ), Dysfunctional Attitudes Scale (DAS), and Sociotropy/Autonomy Scale (SAS) were substantially correlated. Factor analysis of items from all instruments yielded two stable factors: Dependency(f) and Performance Evaluation(f). All interpersonal scales except that of the DAS showed interactions with frequency of interpersonal but not achievement life events in predicting depression symptoms. Strongest support for the predicted interaction was obtained using Dependency(f). The Achievement vulnerability scales yielded no significant interactions with life event frequencies.
