The few cohort studies that have been conducted to date on YMSM have relied on non-probability sampling methods to construct their cohorts. While these studies have provided valuable information about HIV risk behaviors among YMSM, their(More)
Using logistic and multiple regression, we examined the association between hostility, level of depressive symptoms, and smoking in a sample of 1699 ethnically diverse students in California. Self-reports were collected twice from each student, at the beginning of the 6th and 7th grade years. Among 6th graders who had not smoked, depressive symptoms and(More)
