Abstract: | This research introduces a new construct, gender‐based relationship efficacy, which refers to beliefs about one's ability to relate to own‐ and other‐gender peers. Study 1 investigated 204 fourth graders (M age = 9.56) and confirmed that own‐gender and other‐gender relationship efficacy represent distinguishable aspects of preadolescents' social competency beliefs that are differentially related to outcomes with own‐ and other‐gender peers, including outcome expectancies and friendships with own‐ and other‐gender peers. Study 2 provided further evidence of the distinctiveness of relationship efficacy for own‐ and other‐gender peers among 403 seventh (M age = 12.48) and 453 eighth (M age = 13.50) graders and found gender and age differences. Developmental changes and implications for research on intergroup relationships are discussed. |
