College students' relationships with siblings.

Two hundred and seventy-five college undergraduates coming from families of 2-7 children completed questionnaires about their relationships with their siblings. Aspects of intersibling communication, influence, and current and past affective relationships were investigated. The relationships reported were generally more positive than those revealed in other investigations of younger children. Presence of two parents in the home, size of the sibling group, and ordinal position of the respondent student had particular effects upon reported relationships. Furthermore, there were qualitative differences in the relationships between sibling pairs of different ordinal statuses. Results indicate that relationships between siblings have both complementary and reciprocal features, and caution against unidimensional characterizations.
