This study examined the influences of generational status, self-esteem, academic self-efficacy, and perceived social support on 367 undergraduate college students' well-being. Findings showed that 1st-generation students reported significantly more somatic symptoms and lower levels of academic self-efficacy than did non-1st-generation students. In addition, students' generational status was found to moderate predictive effects of perceived family support on stress. Implications for professional practices, limitations, and directions for future research are discussed. (Contains 3 tables.)
