A Methodological Review and Critique of the "Intergenerational Transmission of Violence" Literature.

Exposure to interpersonal or interparental violence (EIPV) and child abuse and maltreatment (CAM) are associated with an increased risk of maladaptive outcomes, including later involvement in adulthood intimate partner violence (IPV; often referred to as the theory of intergenerational transmission of violence). Recent meta-analyses, however, have documented a weak effect size when examining this association. By focusing on young adulthood, a development stage in which identity development and romantic relationship formation are salient tasks, we can provide insight into the association between EIPV, CAM, and IPV. Guided by the methodological critiques from the IPV and EIPV literatures, the present study reviewed the methodology used in 16 studies (published between 2002 and 2016) that tested the theory of intergenerational transmission of violence. The review study focused on how EIPV, CAM, and young adult dating violence were measured and analyzed, with the initial goal of better understanding how methodological decision informed the study's findings. Ultimately, we determined that there was simply too much methodological variability and yet too little methodological complexity to truly inform a review and discussion of the results; therefore, our review solely focused on the study's methodological decisions. Based on our review, we suggest that both of these challenges, too much variability and too little complexity, hinder our ability to examine the theory of intergenerational transmission of violence. Future research must strike a balance between methodological consistency and complexity to better understand the intricate nuances of IPV experiences and inform practice.
