Exposure to marital conflict: Gender differences in internalizing and externalizing problems among children

Marital conflict is integral to children's psychosocial well-being. Extant research has shown that the effects of marital conflict on children are likely to vary by gender, indicating that gender plays a significant and complex role in the relationship between marital conflict and child adjustment. Focusing on gender, this study investigates the link between specific marital conflict tactics and children's mental health symptoms in families in which the parents live together.

This study gathered data from 799 children and their parents in Japan by means of a questionnaire focusing on marital conflict and child behavioral problems. Marital conflict (verbal aggression, physical aggression, stonewalling, avoidance-capitulation, child involvement, and cooperation) was assessed using a Conflict and Problem-Solving Scale. Children's behavioral problems (externalizing and internalizing symptoms) were assessed using the Strengths and Difficulties Questionnaire.

The findings highlight the significant impact of specific interparental conflict on children's behavioral problems, demonstrating that there are differences according to the child's gender. More specifically, multivariate analyses targeting boys revealed that cooperation was significantly inversely associated with externalizing problems and internalizing problems, while avoidance-capitulation and verbal aggression were significantly positively associated with externalizing problems. In contrast, multivariate analyses targeting girls revealed that cooperation was significantly inversely associated with externalizing problems and internalizing problems, while avoidance-capitulation and stonewalling were significantly positively associated with internalizing problems.

This study reveals that interparental conflict is associated with children's behavioral problems. Constructive marital conflict was significantly inversely associated with externalizing and internalizing problems in both boys and girls. Meanwhile, destructive marital conflict (i.e., avoidance-capitulation and verbal aggression) was significantly positively associated with externalizing problems in boys and significantly positively associated with internalizing problems in girls. These findings contribute to the substantial literature demonstrating the relationship between family processes and the development of disruptive behavior disorders in children.
