摘要:This study explored how communication with parents,relations with teachers and intra- and extra-mural activities were related to peer relationships. Data were collected from 453 middle school students in the city of Iksan. Results showed that students with more harmonious communication with parents reported more desirable peer relationships. More familiar and friendly relations with teachers was also associated with more harmonious peer relationships. As adolescents appeared more vigorous in intra- and extra-mural activities,they had friendlier peer relationships. Gender,communication with fathers,relations with teachers,and infra- and extra-mural activities had significant effects on peer relationships. Relations with teachers was the best predictor for peer relationships..
