The Global Appraisal of Individual Needs (GAIN) originated in 1993 as a collaborative effort between clinicians, researchers and policymakers to create a comprehensive and standardized biopsychosocial assessment tool.
Since then, it has developed into a progressive and integrated family of instruments with a series of measures and computer applications designed to support a number of treatment processes, including:
Initial screenings (GAIN-SS)
Brief interventions and referrals (GAIN-Q3)
Standardized clinical assessments for diagnosis, placement, and treatment planning (GAIN-I)
Monitoring change in clinical status, service utilization, and costs to society (GAIN-M90)
Subgroup and program-level needs assessments, evaluation and secondary analysis.
The GAIN family of instruments is appropriate for use with both adolescents and adults from a variety of populations in various levels of care.
