Research and evidence base
The Hazelden Co-occurring Disorders Program was developed by members of the faculty from the Dartmouth Psychiatric Research Center. They are leaders in the field of co-occurring disorders in research, clinical experience, and expertise in addressing the complex issues in treating substance use and mental health disorders.
Based on established protocols
The Hazelden Co-occurring Disorders Program is based on the findings, observations, and studies of more than 200 addiction treatment programs using the Dual Diagnosis Capability in Addiction Treatment (DDCAT) Index. The DDCAT was developed to assess the capacity of an addiction treatment program to provide evidence-based services to people with co-occurring disorders.
The Hazelden Co-occurring Disorders Program is the only comprehensive, manualized program for people with non-severe mental illness that co-occurs with a substance use disorders. The program draws upon the numerous randomized controlled trials testing the Integrated Dual Disorders Treatment (IDDT) model, which is designed to treat severe mental health disorders.
A description of this evidence base -- from investigative to promising to established practices -- is included in each component of the program.
In some components, such the Family Program, a careful adaptation of evidence-based practices was made in order to be relevant for people in addiction treatment programs who also suffer from non-severe mental health disorders.
Each component in the Hazelden Co-occurring Disorders Program includes a CD-ROM with a list of the 25 most relevant articles related to the treatment of co-occurring disorders. On some of the CD-ROMs, certain articles are included in their entirety.
