Objective: In this organizational case study the authors pilot a new protocol for evaluating and developing trauma-informed care in behavioral health settings. Methods: A mixed methods design was used to collect data with three instruments: the Adverse Childhood Experiences, the Consumer Perceptions of Care, and the Community Readiness Model key informant interview. Adults (N = 138) in a behavioral health residential treatment program provided a consumer perspective on trauma and integrated services. Providing the staff perspective, key informant interviews of staff (N = 7) were conducted and the overall protocol's utility was assessed. Results: Results indicate the protocol is an efficient, strength-based, and culturally sensitive assessment approach that provided valuable data about the agency's prevalence of consumer trauma, level of integrated trauma-informed services, and readiness to advance a trauma-informed organizational culture. The piloted protocol also fostered understanding of trauma-informed care principles among staff and improved awareness of how to enhance the level of trauma-informed services at their agency. Conclusions: In addition to providing assessment data, the protocol helped agency staff and leadership to fully engage and mobilize toward change. Further application of this tool and future research are discussed. (Journal of Dual Diagnosis, 7:228-241, 2011)
