Adolescent Self-Rated Depressive Symptoms in a Swiss Epidemiological Study

The correlates of self-rated depressive symptoms were examined in an epidemiological sample of Swiss adolescents. Subjects, aged 12 to 17 years, were assessed using the Center for Epidemiological Studies Depression Scale, a Life Event Scale, scales measuring self-related cognitions, coping capacities, perceived parental behavior, school environment, and social network. Based on the distribution of the depression scores, 3 subsamples of nondepressed, moderately depressed, and severely depressed subjects were formed. The severely depressed group was clearly differentiated from the other two groups by almost all scales, with a special relevance of negative self-esteem and the impact of life events. The results of this epidemiological study indicate that various factors reflecting personality, life-events, and the psychosocial environment relate to adolescent depression.
