IOP

Also written as: IOP — Intensive Outpatient Program

Structured outpatient treatment program requiring multiple sessions per week for substance use or mental health disorders.

Full Definition

Intensive Outpatient Program (IOP) is a level of care that provides structured treatment while allowing patients to maintain work, school, or family responsibilities. IOPs typically require 9-19 hours per week of programming, including individual therapy, group counseling, psychoeducation, and family sessions. These programs serve as step-down care from residential treatment or as an alternative to inpatient hospitalization for patients who need more support than traditional outpatient therapy. IOPs are commonly used for substance use disorders, depression, anxiety, and eating disorders.

Usage

Usage note: IOP is standard abbreviation; spell out on first use in patient-facing materials.
