This study examined the relationship between subjective well-being criteria (negative affect, positive affect, and subjective well-being) and individual, family, friend, school, and neighborhood predictor variables in 159 ethnically diverse, urban adolescents. Results indicated that negative affect was significantly predicted by family variables, positive affect was significantly predicted by individual, school, and friend variables, and satisfaction with life was significantly predicted by individual and family variables. Limitations, directions for future research, and clinical implications of these findings are discussed. (Contains 4 tables.)
