Examining treatment outcomes of nonresidential and residential treatment programs may suggest best practices for Indigenous communities delivering treatment services. A systematic review of peer-reviewed and gray literatures comparing treatment outcomes for Indigenous populations was completed. Three studies compared treatment outcomes and reported varying results. Reported outcomes were retention and relapse rates, cultural knowledge, and participant treatment duration. Most retrieved studies described residential treatment outcomes, but it was unclear whether this modality is the best option for Indigenous people seeking treatment. Further research describing treatment modalities, across a continuum of care, situated within culturally developed treatment frameworks is required.
