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.

Gender differences in depression: historical changes

Depression has been widely reported to be more prevalent among females than among males. In this study we demonstrate that gender differences in depression occur only among individuals born during particular historical periods, and test the utility of a model focusing on changes in women's opportunities for academic and professional achievement in predicting periods of significant gender differences in depression. Based on reanalysis of data reported by Klerman et al., we find gender differences in depression among people 40 years of age and older to be high among cohorts that reach adolescence during periods of increasing opportunities for female achievement. Among cohorts that reach adolescence during periods of stable or decreasing opportunities for women, gender differences in depression are not significant at any age.
