The primary goal of this study is to utilize this opportunity as a real-world platform for addressing three key questions that need to be answered prior to wide-scale implementation of the KEEP intervention. First, do the effects of the KEEP parent training generalize (concurrently) to other children currently in foster and kin intervention homes and lead to reductions in overall levels of behavior problems? Second, does the KEEP intervention continue to have effects after the completion of the intervention and generalize (temporally) to new children who enter the homes of these families at a later point in time? Finally, as the KEEP intervention is being implemented by a community agency in a real-world system of care, can the intervention be delivered and maintained in a manner that preserves the goals and quality of the intervention?
