Beyond Parental Behavioral Control: The Mediating Role of Child Disclosure in Adolescent Externalizing Problems

Externalizing problems are influenced by family dynamics, yet the specific mechanisms linking parental control to distinct externalizing problem behaviors remain unclear. This study examined the effects of parental behavioral control on proactive aggression, reactive aggression, and delinquent behavior, focusing on the mediating role of child disclosure. Data were collected from 3818 adolescents (aged 10–18) and their parents in Hong Kong. Results revealed that child disclosure served as a robust mediator. For mothers, full mediation was observed across all three outcomes. For fathers, full mediation was found for both subtypes of aggression, whereas partial mediation was observed for delinquent behavior. The indirect pathways were invariant across gender, suggesting the mechanism is universal. Notably, the model significantly predicted reactive aggression through a full mediation model from both mother and father. The study highlights the unique dual-pathway role of fathers—combining structural deterrence for delinquent behavior with relational communication for aggression and supports the efficacy of trust-based interventions for diverse externalizing problems. These findings suggest that effective parenting operates primarily by fostering a disclosure-promoting context rather than mere surveillance.
