The goal of this study was to examine the relationship between maternal acceptance-rejection and children's social competence and the role that maternal acculturation (ie, American orientation, Korean orientation) played in this relationship in a sample of 53 Korean American mothers. Self-report data were analyzed using Pearson correlations and multiple hierarchical regressions. Low maternal acceptance-rejection was positively related to children's low social competence. Mothers' American orientation had a moderating effect on the relationship between maternal acceptance-rejection and children's social competence. Findings indicate the importance of providing parenting guidelines to mothers who are low on both acceptance-rejection and American orientation.
