Glossary of Terms

Integrated Dual Disorder Treatment (IDDT)
A way of treating individuals with mental illness and substance use disorder. IDDT provides individualized coordinated treatment and rehabilitation of both disorders in one setting and by one team of clinicians. Studies have shown this method of dual intervention leads to better patient outcomes than non-integrated interventions in substance abuse, psychiatric symptoms, housing, hospitalization, arrests, functional status and quality of life.
Integrated Treatment
The care that results from a practice team of primary care and behavioral health clinicians, working together with patients and families, using a systematic and cost-effective approach to provide patient-centered care for a defined population. This care may address mental health and substance abuse conditions, health behaviors (including their contribution to chronic medical illnesses), life stressors and crises, stress-related physical symptoms, and ineffective patterns of health care utilization.
Intellectual and Developmental Disability (I/DD)
Intellectual disability disorders are characterized by a limited mental capacity and difficulty with adaptive behaviors. Developmental disability refers to severe long-term disability that affects cognitive ability and/or physical functioning. The latter encompasses the former but also includes physical disabilities and manifests by age 22.
