<p>Theoretical and empirical evidence indicates that parental conflict substantially influences adolescent problem behaviors. This study investigates the impact of parental conflict on children’s internalizing problems and examines the mediating roles of psychological resilience and active coping, as well as the moderating effect of friendship quality. A total of 1030 adolescents were involved. Results showed that (1) Internalizing problems are positively correlated to parental conflict and negatively correlated to psychological resilience, active coping, and friendship quality. (2) Parental conflict has direct and indirect impacts on adolescents’ internalizing problems, with the latter being exerted through three pathways: the separate mediating effects of psychological resilience and active coping, as well as the sequential mediating effect of both factors. (3) Friendship quality moderated the positive influence of psychological resilience on active coping. Friendship quality enhances the impact of psychological resilience on active coping. Specifically, the association between psychological resilience and active coping was stronger in groups of adolescents with high friendship quality than in groups with low friendship quality. Possible explanations and suggestions are given to mitigate the influence of parental conflict on adolescents’ internalizing problems based on these findings.</p>
