Attributional processing style differences in depressed and nondepressed individuals

A series of four studies used different measures to assess the amount of attributional processing following failure and success. It was found that, from an actor's point of view, relatively depressed students consistently differed from relatively nondepressed students in the amount of their attributional processing. The depressed individuals reported more attributions for both hypothetical and real failure, compared to the nondepressed individuals. They also reported fewer attributions for hypothetical success than the nondepressed individuals. In line with previous findings, depressed individuals took less personal credit for their successes and ascribed their failures more pronouncedly to their lack of ability. The findings reflect a depressive attributional processing style that encompasses individual differences, both in the content and in the amount of causal thinking following failure and success. Integration of this style into the attributional helplessness model of depression is suggested. The findings are compatible with a differential self-esteem view of depression and with aspects of Kuhl's functional helplessness model of depression. Implications for depression therapy are briefly discussed.Financial support for the studies was obtained from the University of Bielefeld (Grants 0Z 2760/2774). I wish to thank Karola Bettmer, Thomas Feld, and Stefan Wächter for their participation in the collection and the preparation of the data, as well as Friedrich Försterling, Jonathan Harrow, Wulf-Uwe Meyer, and two unknown reviewers for their helpful comments on earlier versions of this paper.
