Alcohol self-assessment

Alcohol (AUDIT-C) self-assessment

A three-question screen for whether your drinking may be putting your health at risk.

This is a screening tool, not a diagnosis. It cannot examine you or tell you what is wrong — it only helps you understand your answers and decide whether to seek help. Discuss your result with your GP. For urgent advice call NHS 111; in an emergency call 999. Nothing you enter here is stored or sent anywhere — it is scored entirely in your browser.

AUDIT-C is a short, validated set of three questions developed from the World Health Organization’s AUDIT, and used across the NHS to identify drinking that may be harming your health. In the UK, one unit is roughly half a pint of ordinary-strength beer, a single 25ml measure of spirits, or about half a small glass of wine. It is a screening aid, not a diagnosis.

1How often do you have a drink containing alcohol?
2How many units of alcohol do you drink on a typical day when you are drinking?

A pint of higher-strength lager is about 3 units; a large (250ml) glass of wine is about 3 units.

3How often have you had 6 or more units (if you are a woman), or 8 or more units (if you are a man), on a single occasion?
