ASSIST Screening Test: Questions, Scoring, Risk Levels, and Clinical Use

The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) is a World Health Organization questionnaire that screens multiple substance categories and produces a separate risk score for each substance. It supports brief intervention or referral; it does not establish a substance use disorder diagnosis.

ASSIST covers alcohol, tobacco, and multiple drug categories in one substance-specific interview. DAST-10 is narrower because it asks about drug-related problems while excluding alcohol and tobacco from its core score.

What does the ASSIST screen for?

ASSIST screens for tobacco, alcohol, cannabis, cocaine, amphetamine-type stimulants, inhalants, sedatives, hallucinogens, opioids, and other drugs. The tool records whether a person has used each category and then asks follow-up questions about recent use, craving, consequences, and dependence-related experiences.

Its substance-by-substance structure matters when more than one substance is present. A single overall “addiction score” would hide the difference between alcohol risk, opioid risk, and risk from another drug.

What questions are included in the ASSIST?

The ASSIST questions move from lifetime exposure to recent use and substance-related harm. The sequence asks about lifetime use, frequency of use in the past three months, strong urges, health or social problems, failure to meet responsibilities, attempts to cut down, and injection-related risk.

The questionnaire uses the same clinical sequence across substance categories, but the response is scored separately for each category. It is not a symptom checklist for diagnosing a disorder.

How is the ASSIST administered?

A trained health professional usually administers the ASSIST as a structured interview, although a self-completed format may be used when the setting supports it. The person answers the same substance-specific questions, and the clinician reviews the result in context.

Privacy, language access, recall, stigma, and the clinician’s ability to respond to a positive result affect the usefulness of any self-report screen. A score should lead to a conversation and assessment, not an automatic label.

How long does the ASSIST take?

The full ASSIST usually takes about 5 to 10 minutes, with longer administration when several substance categories require follow-up. The time depends on the number of substances reported, the response format, and the detail needed to clarify risk.

How is the ASSIST scored?

ASSIST adds the scored responses for each substance and reports a substance-specific risk score. The score range differs by substance category because tobacco has a different scoring range from alcohol and other drugs.

Risk band	Alcohol	Other substances	Usual response
Lower risk	0–3	0–10	Information and prevention
Moderate risk	4–26	11–26	Brief intervention
Higher risk	27 or higher	27 or higher	Further assessment and possible specialty referral

The score indicates the level of follow-up suggested by the tool. It does not determine a diagnosis, severity, medical necessity, or level of care without a clinical assessment.

What happens after a positive ASSIST result?

A positive ASSIST result is followed by feedback, brief intervention, or a fuller assessment based on the substance, risk score, symptoms, safety concerns, and the person’s goals. The result can also prompt screening for withdrawal risk, overdose risk, mental-health symptoms, and social needs.

When follow-up identifies depression, anxiety, trauma symptoms, mania, psychosis, or suicide risk, condition-specific mental-health screening tests can organize those concerns while a clinician determines whether they are independent, substance-induced, or urgent.

When the assessment identifies a need for structured care, the decision about drug or alcohol rehab depends on clinical findings rather than the ASSIST score alone.

How is ASSIST different from DAST-10 and CRAFFT?

ASSIST is the broad multi-substance option; DAST-10 focuses on drug-related problems, and CRAFFT is designed for adolescents and young adults. The tools answer different screening questions and should not be treated as interchangeable versions of one test.

For alcohol-specific concerns, the AUDIT has a narrower alcohol focus. A clinician chooses the instrument based on the person’s age, substances, setting, and the follow-up care available.

What are the limits of the ASSIST?

ASSIST is limited by self-report bias, recall error, incomplete disclosure, language and cultural fit, and the absence of a diagnostic interview. It also cannot measure intoxication, impairment, withdrawal severity, or biological exposure at the time of screening.

A positive result needs clinical follow-up, and a negative result does not rule out a problem when symptoms, safety concerns, or collateral information point elsewhere.
