This study examined the role of filial responsibility as a mediator between parental depression and posttraumatic stress symptomatology (PTSS) in Bosnian youths. The sample consisted of 145 6PthP-8PthP grade boys and girls and their parents. Unfairness and caregiving scales were combined in an interaction term to test the hypothesis. Parental depression significantly predicted parental report of adolescent PTSS but the filial responsibility variables did not significantly mediate the relationship between parental depression and PTSS. A post-hoc analysis examined the role of filial responsibility mediating the relationship between parental education level and PTSS. The interaction terms did not significantly mediate the relationship but the unfairness variable significantly mediated the relationship between parental education level and adolescent report of PTSS.
