Patterns of Intimate Partner Violence in Mothers At-Risk for Child Maltreatment

Using three interviews spanning 3 years, we identified intimate partner violence (IPV) classes and determined how class membership changed over time amongst a sample of 217 mothers at-risk for child maltreatment that were enrolled in an early childhood home visitation evaluation study. Data on perpetration/victimization, IPV type (verbal, physical, and sexual abuse and injury) and severity were used to conduct latent class analyses at each time point. Latent transition analyses established the proportion of mothers who changed classes over time. A three-class solution (minimal, moderate, and high IPV) was indicated at each time point. All classes included mutual IPV. Partners used minor verbal abuse in the minimal class, minor and severe verbal abuse and minor physical abuse in the moderate class, and all IPV categories in the high class. At each transition, 40% or more moved from minimal to moderate or high IPV. This movement emphasizes the need to screen women frequently and develop interventions recognizing the dynamic nature of IPV.
