DIAGNOSIS: Substance-Use Disorders

TREATMENT: Group MATRIX Model Therapy for Cocaine Use Disorders


  • Basic premise: The Matrix Model is an integrative treatment model originally developed in response to the cocaine epidemic of the 1980s. The program consists of relapse prevention groups, education groups, social support groups, individual counseling, self-help participation, and urine and breath testing delivered in a structured manner over a 16-week period. The treatment is a directive, non-confrontational approach which focuses on current issues and behavior change. Therapies that are frequently incorporated in the Matrix Model include cognitive-behavioral therapy (CBT), contingency management, 12-step facilitation, motivational interviewing, and family therapy.
