School success is associated with parent- and peer-relationships. To study the connection between these alliances and school success, 30 African-American and 30 European-American 6th graders were given the Relationship Closeness Inventory, Network of Relationships Inventory, Self-Perception Profile, Revised Class Play, and Youth Self-Report. A parent and best friend also completed surveys. Results show parent and peer support relates to the social competence of youth. Father support is associated with female aggressive-disruptive behavior, and best friend support is associated with sensitive-isolated behavior in boys. African-American parents do more social events with their children than European-American parents do with their children. European-Americans and males have higher socioeconomic status than African-Americans and females.
