The DDCAT Index is a fidelity instrument for measuring addiction treatment program services for persons with co-occurring disorders.
Fidelity scale methods have been used to ascertain adherence to and competence in the delivery of evidence-based practices. This methodology has been used to assess mental health program implementation of the Integrated Dual Disorder Treatment (IDDT).
IDDT is an evidence-based practice for persons with co-occurring disorders in mental health settings, and who suffer from severe and persistent mental illnesses. The DDCAT utilizes a similar methodology as the IDDT Fidelity Scale, but has been specifically developed for addiction treatment service settings.
Further, addiction treatment services for co-occurring disorders are guided by an amalgam of evidence-based practices and consensus clinical guidelines. The IDDT model has been studied in effectiveness trials and has been designated as an evidence-based practice.
