Does marital satisfaction predict children aggression? Insights from parents' and children's psychological distress

Marital satisfaction is a key indicator of family members' life satisfaction and mental and physical health. Parents' marital functioning affects their children's development. Given the significant impacts of marital satisfaction on children's psychological and behavioural development, the influencing paths need to be explored. This study aims to extend prior research by examining the direct effect of marital satisfaction on children's aggression and the intermediary roles of parents' and children's psychological distress. Using multi-stage cluster random sampling, a total of 971 children and their parents were recruited in Shaanxi Province in Mainland China. Self-reported questionnaires regarding marital satisfaction, psychological distress and aggression were completed. Results showed no significant direct impact of marital satisfaction on children's aggression, but children's psychological distress mediated this link. Moreover, parents' and children's psychological distress served as sequential mediators in the nexus between marital satisfaction and children's aggression. It means that a chain mediating mechanism existed. A better understanding of the underlying mechanisms may offer valuable insights that would aid policymakers and clinicians in designing effective prevention and interventions targeting children's behavioural problems.
