BASIS-T®

Outcome measurement from the adolescent’s perspective.

The 25-item Behavior and Symptom Identification Scale-Teen, BASIS-T®, is a behavioral health assessment tool designed to assess the outcome of mental health or substance abuse treatment from the adolescent’s perspective. Typically, BASIS-T® is given at admission and discharge for inpatient or residential programs, and at intake/initiation of treatment and then periodically thereafter in partial hospital or outpatient settings. Grounded in the latest scientific methods of survey development and validation, the BASIS-T® underwent extensive testing as part of a multi-year research and development process.
