Short Michigan Alcohol Screening Test

The Short Michigan Alcohol Screening Test (SMAST) is a 13-item yes/no self-report questionnaire that screens adults for signs of a possible alcohol use problem. Condensed from the original 25-item Michigan Alcoholism Screening Test, it asks about drinking-related consequences across relationships, work, health, and help-seeking to flag people who may need a fuller assessment.

Why healthcare providers use the SMAST

  • Fast, structured screening. Thirteen yes/no items give a standardized read on drinking-related problems in a couple of minutes, without a lengthy interview.
  • Broad view of consequences. The questions span relationships, work, health, and help-seeking, so the screen reflects how drinking affects daily life rather than volume alone.
  • A shared reference point. A single score gives the patient and care team a common starting point for a conversation about alcohol use.
  • Low burden. Because it is short and self-administered, it fits easily into intake without adding much to the patient's workload.

Which settings use the SMAST?

  • Primary care. Used at intake or annual visits to identify patients whose drinking may warrant a closer look.
  • Behavioral health and addiction services. Applied during assessment to help gauge the likelihood of an alcohol problem.
  • Hospital and general medical settings. Helps identify alcohol-related risk among patients presenting for other concerns.
  • Telehealth. As a short self-report screen, it is easy to complete before a virtual visit.

What does the SMAST measure?

The SMAST measures self-reported consequences and perceptions associated with drinking rather than the amount a person drinks. Its 13 items ask about problems that tend to accompany an alcohol use disorder, grouped into a few broad domains:

  • Self-perception of drinking. Whether the person views their own drinking as normal and whether others have expressed concern.
  • Social and interpersonal impact. Effects on family, friendships, and social or occupational functioning.
  • Health and safety consequences. Physical, legal, or safety problems the person links to their drinking.
  • Help-seeking and control. Past efforts to get help, attend support groups, or cut down on drinking.

Scoring the SMAST

  • Number of items. 13 questions.
  • Per-item scale. Each item is answered yes or no, and a response indicating a problem scores 1 point. Most items count a yes answer, while a few are reverse-scored so that a no answer scores the point.
  • Total score range. 0 to 13.
  • Score direction. Higher scores indicate more drinking-related problems and a greater likelihood of an alcohol use problem.

The SMAST is a screening tool, not a diagnosis. Published cutoffs vary slightly across sources: the original scoring treats a score of 3 or more as suggestive of a probable alcohol problem, while some clinical settings apply a more conservative threshold of 4 or more before recommending a full assessment. A positive screen guides clinical decision-making and prompts follow-up rather than confirming a disorder on its own.

Best practices for administration

  • Explain the purpose. Tell patients the questions screen for alcohol-related concerns so they understand why they are being asked.
  • Support honest answers. Ask in a private, nonjudgmental way, since accuracy depends on candid responses.
  • Set a time frame. Clarify the period the questions cover, as the SMAST traditionally asks about lifetime experience with drinking problems.
  • Treat it as a screen. Use a positive result to open a conversation and consider further assessment, not as a standalone diagnosis.
  • Pair with context. Review results alongside history, other screens, and clinical judgment before drawing conclusions.

How Zentake helps with the SMAST

  • Automatic scoring. Zentake totals the SMAST on submit, so there is no hand-tallying.
  • Before the visit. At substance use practices, patients complete it from home on any device, so the clinician starts informed.
  • HIPAA compliant. Data is encrypted, with a signed BAA on every plan.

Frequently asked

Short Michigan Alcohol Screening Test questions, answered.

What is the SMAST used for?

The SMAST is a brief screening tool used to identify adults who may have a problem with alcohol. Its 13 yes/no questions flag drinking-related consequences so clinicians can decide whether a fuller assessment is warranted. It screens for possible alcohol problems and does not, by itself, diagnose an alcohol use disorder.

How many questions are on the SMAST and how is it scored?

The SMAST has 13 questions, each answered yes or no. Responses that indicate a drinking problem score one point, giving a total from 0 to 13. Most items are scored for a yes answer, while a few are reverse-scored so that a no response counts toward the total instead.

What SMAST score suggests an alcohol problem?

Scoring conventions vary slightly. In the original scheme, a score of 0 to 1 shows no indication of a problem, 2 is borderline, and 3 or more suggests a probable alcohol problem. Some clinical settings use a more conservative threshold of 4 or more before recommending a full assessment.

Is the SMAST a diagnostic test?

No. The SMAST is a screening instrument, not a diagnostic test. A positive result signals that alcohol use may be a concern and prompts follow-up, but a diagnosis of an alcohol use disorder requires a clinical evaluation that considers history, other screens, and professional judgment alongside the score.

How is the SMAST different from the full MAST?

The SMAST is a 13-item short form condensed from the original 25-item Michigan Alcoholism Screening Test. It keeps the most discriminating questions so it can be completed faster while still screening for the same drinking-related problems. The shorter length makes it practical for routine intake and busy clinical settings.

Who can complete the SMAST?

The SMAST is designed as a self-report questionnaire, so adult patients usually complete it themselves before or during a visit. A clinician or staff member can also read the items aloud when needed. It is intended for non-geriatric adults; a separate version, the MAST-G, is used for older adults.
