The Global Appraisal of Individual Needs (GAIN) is an evidence-based assessment used with both adolescents and adults and in outpatient, intensive outpatient, partial hospitalization, methadone, short-term residential, long-term residential, therapeutic community, and correctional programs.

It originated in 1993 as a collaboration between clinicians, researchers, and policymakers from over a dozen behavioral healthcare agencies to create a comprehensive biopsychosocial assessment tool. It is a progressive and integrated series of measures and computer applications designed to support a number of treatment practices.

The GAIN has eight core sections: Background; Substance Use; Physical Health; Risk Behaviors and Disease Prevention; Mental and Emotional Health; Environment and Living Situation; Legal; and, Vocational.

GAIN materials are available in hard copy and electronic forms.
