Research shows that interparental conflict is positively associated with internalizing behaviors in children and adolescents, but few have considered these associations among young adults. This study uses the cognitive-contextual framework to explore whether appraisals of threat and self-blame explain the expected associations between interparental conflict and internalizing symptoms in a sample of young adults. Perceptions of interparental conflict, appraisals of threat and self-blame, and two aspects of internalizing symptoms (i.e., depression, anxiety) were measured in 255 undergraduates (ages 18-21) at two Midwestern universities. Parallel mediation models demonstrated an indirect pathway through threat to depressive symptoms. In contrast, the indirect pathway through self-blame was supported when predicting anxiety. The importance of considering interparental conflict and its psychological consequences during young adulthood is discussed.
