Specificity of relations between adolescents' cognitive emotion regulation strategies and symptoms of depression and anxiety.

The aim of this study was to examine the extent to which cognitive emotion regulation strategies were "common or transdiagnostic correlates" of symptoms of depression and anxiety and/or "specific correlates" distinguishing one problem category from the other. The sample comprised 582 13- to 16-year-old secondary school students. Symptoms of depression and anxiety were measured by the SCL-90, and cognitive emotion regulation strategies were measured by the CERQ, in a cross-sectional design. Multivariate regression analyses were performed. Before controlling for comorbidity, the same cognitive emotion regulation strategies that were related to symptoms of depression were also related to symptoms of anxiety. However, after controlling for comorbid anxiety symptoms, rumination, self-blame (only girls), positive reappraisal, and positive refocusing (the latter two inversely) were uniquely (and significantly) associated with depression symptoms; and after controlling for comorbid depression symptoms, catastrophising and other-blame were uniquely related to anxiety symptoms. The results supported the cognitive content-specificity model, in which anxiety is supposed to be uniquely characterised by thoughts concerning the overestimation of threats and harm, and depression is supposed to be uniquely characterised by negative evaluations of self, and of past and future events.
