How to Write a Substance Use Evaluation: A Comprehensive Guide for Beginners, by Dr. Derek Collins, published by NACATP

What is a substance use evaluation?

A substance use evaluation is a biopsychosocial assessment. The evaluator looks at a person’s biological, psychological, and social history to decide whether they meet DSM-5-TR criteria for a substance use disorder, how severe it is, and what level of care they need under the ASAM Criteria.

A solid evaluation draws on four sources of data: a clinical interview, standardized tests and measures (such as the AUDIT, MAST, DAST, or SASSI-4), collateral interviews, and a review of records. It ends in a written report with a diagnosis, risk assessment, and individualized treatment recommendations.

Why this guide exists

Your report decides somebody’s next chapter

The evaluations you write carry real weight. Your recommendation can decide whether someone goes to jail or into treatment, keeps their job or loses it, or keeps their kids at home or sees them go into foster care.

That’s why a quick “How much do you drink?” doesn’t cut it. Two people can drink the same bottle of wine every night and need completely different care:

Person AAge 45, drinking heavily since a divorce two years ago. Stable job, insurance, supportive friends. May do well in intensive outpatient treatment.

Person BAge 28, drinking since 12, both parents alcoholic, history of homelessness, hepatitis C. May need residential care, medical care, and housing support.

Same diagnosis, different lives, different level of care. This guide teaches you to see the difference and write it down so a judge, probation officer, or treatment provider can act on it.

“For years, I have longed for a practical, authoritative ‘how-to’ guide that I could confidently recommend to students, counselors-in-training, and forensic evaluators. Thanks to Dr. Collins and NACATP, that guide has finally arrived.”

Aaron L. Norton, PhD, LMHC, LMFT, MAC, SAP, CFMHE Executive Director, National Board of Forensic Evaluators, Inc. (from the Foreword)

Common questions

Substance Use Evaluation FAQ

Gather information from four sources: a clinical interview, standardized screening tools, collateral interviews, and a records review. Assess the person’s biological, psychological, and social history. Apply the DSM-5-TR criteria to decide whether a substance use disorder is present and how severe it is. Use the ASAM Criteria to recommend a level of care. Then write it up in a standard report format that ends with a diagnosis, risk assessment, treatment recommendations, and prognosis.

A professional report typically includes: identifying information and referral source; presenting problem; substance use history; biopsychosocial history; mental status examination; standardized assessment results; collateral information; clinical observations; DSM-5-TR diagnosis; risk assessment; strengths and resources; treatment recommendations; prognosis; and the evaluator’s name, credentials, and signature.

A biopsychosocial assessment looks at the whole person. Bio covers the body, genetics, and medical history. Psycho covers thoughts, feelings, and mental health. Social covers relationships, work, family, legal history, and living situation. It is the foundation of a modern substance use evaluation.

Common standardized tools include the AUDIT (Alcohol Use Disorders Identification Test), the MAST (Michigan Alcohol Screening Test), the DAST (Drug Abuse Screening Test), and the SASSI-4 (Substance Abuse Subtle Screening Inventory). Drug testing may also be used. The guide explains when each tool fits. Each tool must be administered according to its official guidelines and training requirements.

DSM-5-TR lists 11 criteria for substance use disorder. Severity is based on how many are met: 2–3 is mild, 4–5 is moderate, and 6 or more is severe. Chapter 3 of the guide explains each criterion in plain language.

The ASAM Criteria, 4th Edition organize care into four primary levels, each with sublevels: Level 1 is outpatient, Level 2 is intensive or high-intensity outpatient, Level 3 is residential, and Level 4 is medically managed inpatient treatment. Evaluators assess six ASAM dimensions to match a person to the right level. Early intervention is still important, but in the 4th Edition it is no longer counted as a level of care. Chapter 6 covers each level and the most common decision points.

It’s written for beginners and developing professionals: counselors, social workers, psychologists, and evaluators who work with court-involved or high-risk clients, including DUI, probation, diversion, and child welfare referrals, as well as private practice clinicians.

No. The guide is an educational resource that supports training and clinical supervision. It is not a substitute for formal education, licensure, or certification. Who may perform court-ordered or forensic evaluations is set by the laws and licensing rules in your state.

Yes. Chapter 10 includes three complete sample evaluations with detailed justifications: a mild alcohol use disorder, a severe opioid use disorder, and polysubstance use with a co-occurring disorder.
