", "\nABSTRACT\nPrior research has identified interparental conflict management as a significant predictor of child behavioural development, while investigations into the specific interparental conflict management strategies remain limited in scope. Furthermore, the mediating and moderating mechanisms remain poorly understood. The present study addresses these gaps by exploring the mediating role of child maltreatment in the association between interparental conflict management strategies and adolescent behavioural problems while also examining gender as a moderator of these indirect pathways. This study utilized a sample of 10 174 cohabiting married couples with at least one child in Zhejiang Province, China (mean of age = 38.03; 75.64% female). The empirical results revealed that conflict engagement, compliance and withdrawal strategies positively predicted antisocial behaviour, whereas problem‐solving exhibited a negative association. Moreover, the study uncovered the mediating role of child abuse and neglect and the moderating role of parental and child gender. These findings offer critical empirical groundwork for family social workers and policymakers to develop targeted interventions and social policies aimed at mitigating behavioural problems.\n"]
