Attributional and social comparison processes in depression.

In this study we examined the consequences for depressed and nondepressed individuals of receiving comparison feedback regarding their causal understandings of an event. Specifically, the effects of similar, dissimilar, or no-comparison feedback on depressed and nondepressed subjects' evaluations of the comparison other and on their feelings about themselves were investigated. Because the reduction of uncertainty about one's conception of social reality is a major motive underlying social-comparison processes, we expected that depressed individuals, who are assumed to have experienced heightened uncertainty associated with frequent exposure to uncontrollable life events, would be more motivated to engage in social comparison and would be more sensitive to social-comparison feedback. Results generally were consistent with this reasoning. The implications of the results in terms of the development and maintenance of depression were discussed.
