The majority of children with traumatic experiences who seek treatment have had multiple traumatic experiences resulting in complex trauma. Complex trauma is associated with multiple adverse outcomes for children and caregivers. Treating complex trauma has the potential to significantly improve child mental and physical health, caregiver mental health, and reduce family conflict. One promising approach is the Attachment, Regulation, and Competency (ARC) Framework. Yet, there is limited research on the effectiveness of interventions using the ARC framework. The purpose of this rapid scoping review was to assess the state of the evidence of ARC and ARC adaptations. The databases APA PsycINFO, Social Work Abstracts, and Applied Social Sciences Index & Abstracts were searched. The search was limited to articles involving interventions using the ARC framework and written in English. To be as comprehensive as possible quantitative, qualitative and mixed methods designs were included and there was no date restriction. Ten articles were included in the review. Results show all studies were quasi experimental, half did not include a comparison group, and interventions using the ARC framework varied in duration (12-180 sessions), setting (outpatient therapy, residential treatment, community outreach and school-based intervention) and age (birth-22). Findings indicate the ARC framework shows promise in reducing children’s trauma related symptoms including post-traumatic stress disorder (PTSD), externalizing, and internalizing problems, and improving trauma sensitive classroom environments. Additional outcomes included increased permanent placements, reduced caregiver stress and increased caregiver functioning. Future research is needed utilizing randomized controlled trials to establish efficacy of this promising intervention.
