Despite indications that emotional abuse might be the core factor underlying the negative effects of child maltreatment, it has received little attention, particularly with respect to its impact on interpersonal relationships in adulthood. Results indicated that emotional abuse was a stronger predictor of relationship violence than other maltreatment subtypes. Emotion dysregulation partially mediated this relationship, driven by its behavioral component, impulsivity. Gender and ethnicity effects were examined. Findings point to the need for increased attention to adult outcomes of emotional abuse and increased clinical awareness of emotion regulation as a key developmental mechanism of adaptation in adulthood.
