In an inpatient rehab facility, the assessment used to measure outcomes is typically a combination of different assessments depending on the specific goals of the facility and the needs of the patients. One common assessment is the Addiction Severity Index (ASI), which measures the severity of substance abuse and related problems.

Other assessments may include measures of physical health, functional abilities, and quality of life.
