Early experiences and childhood perceptions of interparental conflict (IPC) have consistently been shown to have detrimental consequences for future psychological adjustment, in particular for attachment and couple relationships during adolescence and adulthood. We hypothesized that 1. IPC would predict anxious and avoidant attachment styles, and three relational attitudes associated with couple relationships: sense of relational entitlement, pathological concern, and authenticity; and 2. Attachment style would mediate the associations between IPC and these three relational attitudes. Measures of perceived IPC, attachment orientations, relational entitlement, pathological concern, and authenticity in romantic relationships were completed online by 280 young adults aged 19–32. IPC was positively correlated with anxious and avoidant attachment styles, restricted and inflated sense of entitlement, and pathological concern and negatively with authenticity. A structural equations model showed that IPC predicted avoidant and anxious attachment styles, which positively predicted an inflated and restricted sense of relational entitlement and pathological concern and negatively predicted authenticity. Attachment styles fully mediated the relationships between IPC and the relational attitudes. IPC therefore seems to be related to imbalanced attitudes in romantic relationships, due in part to a propensity toward insecure attachment orientations. Children with insecure attachment who are exposed to significant levels of IPC may be at high risk for relationship problems later in life because of difficulties exposing their vulnerability, assessing need fulfillment realistically, and caring for themselves as well as others. They should therefore be helped to communicate their relational needs to significant others, in particular to their partners.
