Abstract
To determine psychosocial factors associated both with depressive symptoms and with gender differences in depressive symptoms among junior high school students, we conducted self- administered questionnaires using a sample of 2, 660 students of 13 public junior high schools in Okinawa, Japan.
Depressive symptomatology was measured by the Center for Epidemiologic Studies Depression Scale (CES-D). The psychosocial variables examined were life stresses, social support, health practices, self-esteem, and locus of control. Depressive symptoms were positively associated with life stresses and negatively associated with health practices, social support, self-esteem, and internal locus of control. In addition, female students were likely to report more depressive symptoms, life stresses, and low self- esteem and poor health practices. After controlling for the psychosocial variables differed by gender, gender differences in depressive symptoms were eliminated.
In conclusion, for depressive symptoms of junior high school students, life stresses might be risk factors, but positive health practices, social support, high self-esteem, and internal locus of control might be protective factors. Gender differences in depressive symptoms could be explained by the females' elevation on these psychosocial variables.
