The contribution of self-efficacy theory to the understanding of unipolar nonpsychotic depression is critically reviewed in the present investigation. In particular, the evidence for Bandura's (1982) interactive model of depression is analyzed against the background of competing cognitive models and current knowledge regarding the classification and measurement of depression. It is concluded that at present there is insufficient evidence to support Bandura's (1982) proposal. Significant diagnostic, methodological and theoretical problems with the current research are pointed out. Recommendations for more fruitful research are presented.
