Integrated Dual Disorder Treatment Comparing Facilitators and Challenges of Implementation for Ohio and the Netherlands

Integrated dual disorder treatment (IDDT), an evidence-based practice for people with severe mental illness and co-occurring substance dependence, is based on several key principles. This article compares implementation facilitators and challenges between IDDT teams in Ohio and the Netherlands for several items: stage-wise group interventions, participation in alcohol and drug self-help groups, the role of the psychiatrist, and the provision of supervision. Implementation efforts for IDDT have been moving ahead in Ohio since its introduction in 1999. The Netherlands introduced IDDT in 2004. Researchers from the Trimbos Institute in Utrecht have been working with consultants from the Ohio Substance Abuse Mental Illness Coordinating Center of Excellence at Case Western Reserve University, Cleveland, Ohio, to learn about facilitators and challenges related to implementing IDDT.
