We examined the effects of interpersonal functions given to and received from another upon satisfaction with the relationships. One hundred and sixty female junior college students rated the amount of instrumental and emotional functions given toand received from their father, their mother, and their best friend. They rated also the satisfaction with the relationships. As results of the analysis, it was indicated that satisfaction with the relationships was positively correlated not only with the interpersonal functions received from the other but also with the interpersonal functions given to the other. However, the patterns of these correlations were varied as the types of the relationships. On the basis of these results, some fundamental problems of the interpersonal relatinships were discussed, and the importance of the functional meaning of the interaction partner was examined.
