Self-image as a predictor of outcome in adolescent major depressive disorder.

We investigated the ability of a measure of self-image, two measures of depression, and demographic characteristics to predict the outcome of depressive symptoms. Subjects were 47 adolescents who were referred to outpatient treatment for depression. Subjects were assessed for depressive symptoms at three time periods. Self-image as measured by the Offer Self-image Questionnaire (OSIQ) was a significant predictor of depressive symptoms at both 3 months and 1 year. That was independent of initial levels of depression. The two most predictive scales from the OSIQ were the emotional tone and mastery of the external world scales. The results are consistent with previous research indicating the importance of self-image in adolescent depression. The implications of these findings for treatment of adolescent depression are discussed.
