Treatment Planning M.A.T.R.S.: Utilizing the Addiction Severity Index (ASI) to Make Required Data Collection Useful

Responsive imageThe Addiction Severity Index (ASI) is one of the most universally used instruments for the assessment of substance abuse and related problems. This Blending Team has designed products that include a 6-hour training which addresses how to transformrequired "paperwork"into clinically useful information. These products also address the key tenets of treatment objectives and interventions (Measurable, Attainable, Time-Limited, Realistic, and Specific), referred to as Treatment Planning "M.A.T.R.S."

What is the ASI?
The ASI is one of the most reliable and valid measurements of the nature and severity of client problems, and it identifies potential problems in six domain areas: medical status, employment and support, alcohol and drug use, legal status, family/social status, and psychiatric status.

How the ASI can be used by Program Directors

  • Identifies types of client problems not addressed by in-house services
  • Quantifies the severity of client problems or needs over time
  • Provides a quantifiable measure of program success and documents unmet client service needs
  • Includes data needed in reports for TEDS, CARF, JCAHO, grants management, managed care, and other stakeholders
