The Community Mental Health Evaluation Initiative involves six separate evaluation studies of community mental health programs and one methods study, joined together through use of a common data collection protocol. In addition, a multisite comparison of programs is being conducted under the leadership of the Health Systems Research & Consulting Unit, located at the Centre for Addiction and Mental Health. Participating programs are diverse and include both formal services (Assertive Community Treatment Teams, Intensive Case Management) and peer support organizations (consumer and family support initiatives).
