The aim of this study was to investigate the current empirical evidence for organisation‐wide, trauma‐informed therapeutic care models in OoHC. Seven research papers were identified covering three organisational models. Three of the studies assessed the Attachment Regulation and Competency framework (ARC), one study assessed the Children and Residential Experiences programme (CARE), and three assessed The Sanctuary Model. The risk of bias was high in six of the seven studies. Only limited information was provided on the effectiveness of the models identified through this systematic review, although the evidence did suggest that trauma‐informed care models may have significantly positive outcomes for children in OoHC.
