This study compared boys' and girls' coping responses to videotaped representations of marital conflict that varied in conflict content, tactic, and the gender of the parent engaging in conflict behaviour. Participants were 398 children (208 boys, 190 girls) aged 12-13 years old living in the United Kingdom. Child-related conflict exchanges characterized by hostile behaviour (e.g., physical aggression) elicited greater mediation efforts by children. Children were more likely to mediate father-enacted conflict. Girls, relative to boys, endorsed more mediation to fathers' physical aggression and mothers' pursuit of an issue and were more avoiding of mothers' physical aggression and threats to intactness of the family. Findings underscore the importance of considering parent and child gender in determining children's coping efforts in the context of interparental conflict.
