The Boston Consortium Model: Trauma-Informed Substance Abuse Treatment for Women (BCM) program provides a fully integrated set of substance abuse treatment and trauma-informed mental health services to low-income, minority women with co-occurring alcohol/drug addiction, mental disorders, and trauma histories. BCM was developed by a consortium of urban substance abuse and mental health treatment programs as an enhancement to existing substance abuse treatment based on the Trauma Recovery and Empowerment Model (TREM). TREM uses a psychoeducational and skills-building approach to increase a woman’s understanding of the associations among addiction, trauma, mental health disorders, and sexual risk behaviors. It teaches positive and protective coping skills to help women heal from past abuse and avoid future abuse, along with behavioral strategies for reducing trauma symptoms, substance use relapse, and sexual risk.
