In recognition of the multiple pathways through which family and peer systems are linked, this short-term longitudinal study tested a tripartite model of family-peer relationships. One hundred fifty-nine fourth-grade children (82 boys, 77 girls) and their parents participated in a study of the links between parent behaviors and children's peer relations both concurrently and 1 year later. A multimethod approach--including observations of parent-child interactions, parent report, child report, and teacher and peer ratings--was used to evaluate a tripartite model of family-peer relations. Results indicate that parent-child interaction, parent advice giving, and parental provision of opportunities by both mothers and fathers predict children's social competence and, in turn, social acceptance 1 year later. Suggestions for future research and practical implications are noted, and limitations of the study are acknowledged. (Contains 2 tables, 2 figures, and 1 footnote.)
