Examined the relation of dependency and self-criticism to social functioning among adolescents. Subjects were 7th-11th graders from a suburban high school who completed the Depressive Experiences Questionnaire for Adolescents (DEQ-A) and the Inventory of Interpersonal Problems (IIP). The results showed that self-criticism was strongly associated with reporting a greater number of interpersonal problems, particularly in the areas of sociability and control. Dependency was only marginally related to interpersonal difficulties. The results also showed that levels of self-criticism tended to decline steadily across the high-school years, whereas levels of dependency followed a U-shaped curvilinear pattern in which it was higher in the early and late high school years relative to the middle years. Finally, the present study provides initial evidence of a reliable, shortened 20-item version of the DEQ-A.
