Recent work on social support in marriage indicates that the link between marital satisfaction and social support is stronger for wives than husbands (D. Julien and H. J. Markman; see record 1992-08896-001). Hypotheses based on these findings and on studies of interpersonal perception were tested on a sample of 69 older married couples (mean age 74 yrs). The separate effects of giving, receiving, and reciprocity on spouses' marital satisfaction and well-being were examined. Analyzing the data separately for husbands and wives reveals that perceptions of social support in marriage are more strongly related to the marital satisfaction and general well-being of wives than husbands. Methodological and theoretical interpretations are offered that shed light on the differences between men and women in the meaning of social support in marriage.
