This study examined the moderating effect of perceived social support on the association of dysfunctional attitudes with depression among Taiwanese adolescents. Seventh graders (N = 458) completed the Dysfunctional Attitudes Scale (Weisman & Beck, 1978), Perceived Social Support from Family and Friends (Procidano & Heller, 1983), Stressful Life Events (Chiu, 1988), and Children's Depression Inventory (Kovacs, 1981). The results indicated that perceived social support from friends moderates the relationship between dysfunctional attitudes and depression, implying that as peer support increases, the positive relationship between dysfunctional attitudes and depression weakens.
