Dual diagnosis capability in mental health and addiction treatment services: an assessment of programs across multiple state systems.

Despite increased awareness of the benefits of integrated services for persons with co-occurring substance use and psychiatric disorders, estimates of the availability of integrated services vary widely. The present study utilized standardized measures of program capacity to address co-occurring disorders, the dual diagnosis capability in addiction treatment and dual diagnosis capability in mental health treatment indexes, and sampled 256 programs across the United States. Approximately 18 % of addiction treatment and 9 % of mental health programs met criteria for dual diagnosis capable services. This is the first report on public access to integrated services using objective measures.
