In this chapter, we explore individual and comorbid risk factors for child physical abuse and partner physical abuse, which include demographic factors (e.g., low income, young age, race, and unemployment), family factors (violence in the family of origin), and individual factors (e.g., alcohol abuse and anger problems). We present prevalence rates for the perpetration and victimization of both partner violence and child physical abuse. Our review leads to several summary observations about victimization and perpetration rates: (1) intimate partner violence (IPV) perpetration and victimization rates are similar between men and women, but women are more likely to experience severe violence and injury, (2) a large discrepancy exists between parent and retrospective reports of child victimization and official reports of abuse, and (3) co‐occurring IPV and child abuse are common and estimated to be present in approximately 25–60% of families with one form present, with larger rates seen in shelter than community samples.
