The mediator role of ruminative thinking style in the relationship between dysfunctional attitudes and depression.

Background: The main aim of the present study was to examine whether ruminative thinking styles (brooding and reflection) mediate the effects of dysfunctional attitudes on depressive symptoms. Methods: 120 psychotropic drug-naive first episode depression patients recruited from Bulent Ecevit University School of Medicine psychiatry department and Zonguldak State Hospital psychiatry department outpatient clinics were involved in the study. Participants completed the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Beck Depression Inventory (BDI), Dysfunctional Attitude Scale (DAS) and Ruminative Responses Scale (RRS-short version). Regression analyses together with the Sobel tests were performed for testing the mediator hypothesis. Results: According to the path model, the level of brooding fully mediated the relationship between dysfunctional attitudes and depressive symptomatology but reflection did not play a mediator role in the relationship between dysfunctional attitudes and depressive symptoms. Conclusions: Assessment of brooding with both mental status examination and specific measurements and focusing on brooding as an intervention strategy would be beneficial components for an effective treatment of depression.
