IDDT

Also written as: IDDT — Integrated Dual Diagnosis Treatment

A comprehensive treatment approach that addresses both mental illness and substance use disorders simultaneously through coordinated services.

Full Definition

Integrated Dual Diagnosis Treatment (IDDT) is an evidence-based practice that provides coordinated treatment for individuals with co-occurring mental health and substance use disorders. IDDT combines mental health and substance abuse interventions delivered by the same treatment team or clinician, rather than requiring individuals to navigate separate systems. The approach emphasizes stage-wise treatment matching interventions to the individual's level of motivation and readiness for change, group treatment modalities, and comprehensive services including housing, vocational, and family supports. IDDT has demonstrated effectiveness in reducing substance use, improving psychiatric symptoms, and decreasing hospitalizations.

Usage

Usage note: IDDT refers to the specific evidence-based model; distinguish from general dual diagnosis treatment approaches.
