The Global Appraisal of Individual Needs (GAIN) originated in 1993 as a collaborative effort between clinicians and researchers to create a comprehensive and standardized biopsychosocial assessment tool. Dr. Michael Dennis, senior research psychologist and director of the GAIN Coordinating Center, led this project
through the development of the GAIN Initial (GAIN-I). His goal was to bridge the gap between clinical research and the growing movement toward evidence-based practice.

The GAIN 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 practices, including:

  • Initial screenings
  • Brief interventions and referrals
  • Standardized clinical assessments for diagnosis, placement, and treatment planning
  • Subgroup and program-level needs assessment, 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. Some of these include:

  • Outpatient
  • Intensive outpatient
  • Short-term residential
  • Long-term residential
  • Therapeutic community
  • School-based programs
  • Co-occurring disorder programs
