Addiction treatment services and co-occurring disorders: Prevalence estimates, treatment practices, and barriers.

As the model for treating co-occurring disorders in addiction treatment settings becomes articulated, service systems need data on prevalence, current practice, and barriers to the implementation of evidence-based practices. A self-report survey was administered to 453 addiction treatment providers (43 agency directors, 110 clinical supervisors, and 300 clinicians) from a single state system of care. Data on prevalence estimates, treatment practices, and barriers to implementing services for co-occurring disorders were obtained.
