Objectives: The purpose of this study was to evaluate Parent-Child Interaction Therapy (PCIT) deployed in a community setting comparing in-home with the standard office-based intervention. Child behavior, parent stress, parent functioning, and attrition were examined. Methods: Using a quasi-experimental design, standardized measures at three time points were collected from parent-child dyads (n = 120) with thirty-seven families completing treatment. Results: Growth modeling analyses indicate significant improvements in child and parent outcomes in both treatment settings with more rapid improvements in parent outcomes within office-based treatment. Attrition was predicted by income and parent functioning. Conclusion: PCIT delivered in the community can produce measureable improvements. In-home PCIT is a feasible option but future research should consider benefits and costs. Treatment completion remains a challenge. (Contains 2 tables and 2 figures.)
