This study examined the generalizability of cognitive models of depression to adolescents and explored developmental differences with regard to depressotypic cognitions. Self-reported depressive symptoms and various hypothesized cognitive correlates (e.g., automatic thoughts, attributions, dysfunctional attitudes) were investigated in a sample of 688 adolescents in grades 7 through 12. Measures of normative adolescent cognitions (e.g., egocentrism, self-consciousness) also were included. There was a strong association between negative thinking and depression in adolescents. There was no association between depressogenic thinking and age, nor did the strength of the association between negative cognitions and depression vary from early to middle adolescence. Finally, negative cognitions were associated with self-report measures of both depressive and anxious symptoms.
