The quality of the maternal bond can be disrupted in women exposed to intimate partner violence (IPV), causing them to be less available to their children. The aim of this study was to examine difficulties in emotional regulation in women exposed to IPV and the impact of IPV on both the maternal bond and posttraumatic symptoms among children. A cross-sectional study was carried out with two groups: IPV dyads (n = 36) comprising mothers who had been exposed to IPV and their children, and control dyads (n = 27) comprising non-abused mothers and their children. Information was obtained via structured interviews including scales regarding IPV, posttraumatic stress disorder (PTSD) symptoms, maternal bond, and difficulties in emotional regulation. Correlation analyses showed a positive association between the severity of IPV, PTSD symptom severity in children, and difficulties of emotional regulation in mothers. They also showed a negative association between IPV and the quality of the maternal bond. Regression models demonstrated that exposure to sexual IPV, maternal difficulties in emotion regulation, and younger age of the mother are important predictors of lower quality of the maternal bond. Difficulties in emotional regulation and sexual IPV disrupted the quality of the maternal bond among women and their children. In addition, lower quality of maternal bond was associated with higher PSTD symptoms among children.
