"The Hazelden Co-occurring Disorders Program" was developed and authored by national leaders in the research and treatment of co-occurring disorders. The program authors are faculty members of Dartmouth Psychiatric Research Center, Department of Psychiatry, Community and Family Medicine Department, and Dartmouth Medical School. The Dartmouth Psychiatric Research Center developed and tested the Integrated Dual Disorder Treatment (IDDT) model, an established evidence-based practice designed for people with severe mental health disorders. "The Hazelden Co-occurring Disorders Program" draws upon the numerous randomized controlled trials using the IDDT model and adapts them for patients with non-severe mental health disorders. This perfect-bound guidebook contains complete instructions for implementing the Hazelden Co-occurring Disorders Program. The guidebook is for a mental health or addiction treatment organization's director, board of directors, CEO, CFO, and other key agency leaders. This guidebook offers all the tools a clinical administrator needs to assess the seven key areas of organizational effectiveness, including the policy, practice, and workforce benchmarks needed to deliver the best possible services to persons with co-occurring disorders. "The Clinical Administrator's Guidebook" also contains a valuable organizational assessment guide, which outlines the steps needed to assess and improve services offered to patients with co-occurring disorders. Links to resources about co-occurring disorders, a sample charter agreement, a sample Dual Diagnosis Capability in Addiction Treatment Index (DDCAT) implementation plan, a patient self-report questionnaire, and other materials are included on the accompanying CD-ROM.
