Examines effects of social connectedness, social appraisal of the campus climate, and perceived stress of college women and men. Social appraisal was hypothesized to mediate the effects of connectedness on perceived stress. Results supported a partial mediation effect for women. Men were more likely to negatively appraise the campus climate, and social connectedness was more negatively related to perceived stress. (Contains 41 references and 2 tables.) (GCP)
