Stress, health-related behavior and quality of life on depressive symptomatology in a sample of adolescents.

This study examined the correlations of 21 variables categorized into sociodemographic, subjective quality of life, stress, problem behavior, and health behavior predictors of at-risk and low-risk depressive symptomatology for a sample of 1056 adolescents attending public school. Discriminant function analysis showed lower life satisfaction, higher stress, and perceived unattractiveness as major discriminating variables for at-risk (CES-Depression score greater than 23) versus low-risk depressed adolescents. Only two problem behaviors were significant, smoking for girls and hard drug use for boys.
