Bowen Family Systems Theory and Social Learning Theory served as a framework for examining the potential role of offspring maternal forgiveness in the intergenerational transmission (IGT) of violence. Using 285 emerging adults, we tested the hypotheses that higher accounts of witnessed interpersonal violence perpetrated by either parent would relate to increased reports of dating violence, and that offspring’s capacity to forgive mothers for current transgressions would mediate this relationship. Witnessing interpersonal violence perpetrated by either parent significantly related to offspring dating violence perpetration and victimization. In addition, witnessing violence perpetrated by either parent significantly related to offspring dating violence perpetration, via offspring’s capacity to forgive. Contrary to expectation, offspring’s capacity to forgive mothers did not mediate the link between father-perpetrated violence and dating violence victimization; however, it did serve as mediator in the association between mother-perpetrated violence and offspring dating violence victimization. Overall, the findings suggest that witnessing violence perpetrated by either parent explains a portion of the variance in offspring dating violence indirectly through offspring’s capacity to forgive mothers for current transgressions. The present study contributes to previous research on the IGT of violence by identifying forgiveness as a mechanism in which intimate partner violence is transmitted generationally. Implications and future directions are discussed for researchers and clinicians.
