Erects of marital communication and friendship- and job-related social activities on emotional support ana alienation among married women and men were examined. Causal analyses of questionnaire responses by 259 women and 185 men indicated that for both women and men, richness of marital communication made the spouse more important as the agent of emotional support, and at the same time decreased alienation. Job-related activities decreased women's alienation, while they tended to increase men's alienation. Men's social activities had a negative influence on their marital relation. In short, women and men appeared to seek different psychological functions in social activities, which in turn determined their levels of alienation.
