Interpersonal betrayal and cooperation: effects on self-evaluation in depression.

Despite numerous studies demonstrating that depressed people are generally self-critical, little is known about interpersonal stressors that may activate or increase this negative self-evaluation. In this study, the effect of interpersonal betrayal and cooperative social interaction on self-evaluation processes in depressed and nondepressed women was assessed. Depressed subjects who experienced interpersonal betrayal were more critical of their performance on a subsequent task than were nondepressed subjects or depressed subjects who had experienced a cooperative interaction. Depressed subjects in the betrayal condition also behaved more aggressively toward their betraying partner than did nondepressed betrayed subjects. Depressed subjects were more critical of their own personality characteristics than were nondepressed subjects, regardless of condition. Results suggest that some negative cognitive schema among depressed persons may be altered by interpersonal factors, although it is not clear whether such effects are secondary to increases in self-criticism after conflict or to decreases in self-critical tendencies after positive interaction. Given the variability in results with different measures of self-evaluation, researchers are urged to use multiple, diverse measures of self-evaluation in future efforts to study variability in self-appraisal.
