児童・思春期の親子関係と外在化型問題行動の関連に対する親友関係の調整効果

抄録

This study investigated the moderating effects of children’s conflicting relationships with their best friends on how positive parent-child relationships buffer against children’s externalizing problem behaviors directly or through their self-esteem. It also examined whether this moderating effect was conditional on children’s age. Nine hundred and twenty-six elementary and junior high school students completed the questionnaire, which covered their sense of trust in parents, self-esteem, conflicting relationships with best friends, and externalizing problem behaviors. The results of a mediation analysis revealed that children’s high sense of trust in parents buffered against externalizing problem behaviors by enhancing their self-esteem. However, moderated mediation analyses indicated that children with highly conflicting relationships with their best friends reduced the buffering effects of children’s sense of trust in parents on externalizing behaviors both directly and through their self-esteem. These findings were discussed in terms of the children’s conflicting relationships with their best friends and the children’s perception of ego-threat.
