This article introduces the ARC model and describes its application with young children of diverse ethnocultural backgrounds involved in the child protection system due to maltreatment. Examination of the clinical application of the ARC model with this population underscores the importance of grounding child complex trauma treatment in the caregiving system. Strategies for successful clinical intervention are identified, with attention devoted to cultural and systemic resources to advance the treatment process. This article presents preliminary evidence of the effectiveness of the ARC model derived from program evaluation conducted at a community-based clinic.en-UScomplex traumatreatmentattachmentdiverse cultural backgroundsArticle
