Purpose <p>Sexual coercion is a form of intimate partner violence that remains understudied despite its negative consequences on both the victim and the relationship itself. Even fewer studies have investigated how individual and relational risk factors contribute to the occurrence of sexual coercion using a dyadic perspective. This study examined the intermediary role of relationship dissatisfaction in the indirect association between the accumulation of childhood interpersonal trauma (i.e., cumulative childhood trauma) and sexual coercion.</p> Methods <p>This research question was tested in two different samples: a sample of 587 men seeking help for IPV-related difficulties and a sample of 145 same- and cross-gender couples from the community answered self-reported questionnaires.</p> Results <p>In the sample of men seeking help, an indirect link was found between cumulative childhood trauma and sexual coercion perpetration through higher relationship dissatisfaction. In the sample of community couples, an indirect partner effect revealed that the respondents’ experience of cumulative childhood trauma was indirectly related to their partners’ sexual coercion perpetration via the respondents’ higher relationship dissatisfaction.</p> Conclusions <p>These findings can help both practitioners and researchers better understand the occurrence of sexual coercion in couples in which one or both partners experience relational dissatisfaction and survived childhood trauma.</p>
