The present study explored the relationship between disclosure of sexual trauma to a romantic partner and relationship satisfaction for individuals who have experienced unwanted or forced sexual contact. We examined whether posttraumatic stress disorder (PTSD) clusters, partner reactions, and perceived partner responsiveness (PPR) mediated that relationship. Relationship satisfaction was significantly, positively correlated with trauma disclosure, positive partner reactions, and PPR, and significantly, negatively correlated with negative partner reactions and the PTSD clusters of avoidance and negative alterations in cognitions and mood. Trauma disclosure had a significant, indirect effect on relationship satisfaction via positive partner reactions and PPR. Findings from this study can be utilized to inform clinical interventions and guide future research for individuals who have experienced sexual trauma.
