Intimate partner violence (IPV) is one of the most prevalent forms of violence against women and has serious negative effects on women's well-being. Research shows that women who are victims of IPV are at an enhanced risk for mental health problems; however, the mechanisms underlying these associations have not been sufficiently understood. The present study aimed to test the serial mediating roles of loneliness and expressive suppression in the association between IPV exposure and depressive and somatic symptoms. The sample consisted of 479 women, aged 18 to 66 (M = 28.81; SD = 10.32), who reported being in a romantic relationship for at least one year. Data was collected via an online survey. Two serial mediation models were tested using the SPSS PROCESS macro, Model 6. The results indicated that IPV exposure had a significant indirect effect on both depressive and somatic symptoms through loneliness, as well as a significant serial indirect effect through loneliness and suppression. The indirect effects through suppression alone were not significant, suggesting that the mediating role of suppression emerged only when preceded by loneliness. These results indicate that loneliness and expressive suppression may be important processes linking IPV to depressive symptoms and somatic difficulties in women. These findings imply that prevention and intervention programs targeting depressive and somatic symptoms in women who are exposed to IPV may benefit from addressing these processes.
