Note. The child victimization variables (Witnessed IPV, Experienced Child Abuse, and Combined Exposure) are a series of dummy variables to represent individuals with the described trauma exposure compared to all others, including the non-exposed comparison group. ECA= Experienced Child Abuse; WIPV=Witnessed IPV LNAPT=Lifetime Non-abuse Potential Trauma Exposure; AAT=Adulthood Abuse Trauma Exposure.
