Child abuse remains a serious and expensive social problem in the United States. Few evidence-based treatments (EBTs) exist for at-risk families and/or maltreating families where neglect or abuse has occurred, limiting the ability of social service agencies to comply with legislative mandates to use EBTs with clients. One promising intervention, parent–child interaction therapy (PCIT), has been tested in 11 separate trials with this population. This review of research on PCIT with abusive adults found that overall PCIT is an appropriate, efficacious intervention method to prevent future maltreatment by targeting parenting skills and child externalizing behaviors. These findings must be taken with caution, since the key factor to determine efficacy is completion of treatment, and all the studies involved showed significant problems with sample attrition. While the current studies are promising, there is a need for research that focuses on measuring parental sensitivity and attachment levels, explores use in the foster and adoptive communities, and studies that use tertiary subjects to serve as unbiased reporters of perceived levels of behavioral changes.
