The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) is a concise, evidence-based screen created by public-health researchers to spot emerging patterns of harmful drinking. Internationally validated across diverse populations, it relies on three behaviour-focused items that quantify drinking frequency, typical volume, and episodes of heavy consumption reported for the previous twelve-month period.

This browser-based tool adapts the AUDIT-C into an interactive, self-scoring experience. A lightweight reactive engine records your answers, updates progress instantly, and calculates the cumulative 0 – 12 score when all items are complete. A semicircular gauge produced by a client-side charting layer visualises severity while colour-coded badges match clinically researched risk bands.

For example, a 35-year-old noting four drinking days per week and eight drinks each time would see a “High Risk” result, underscoring how modest changes lower your score, Results do not constitute a clinical diagnosis.

Technical Details:

Foundational Principles

The AUDIT-C sums three ordinal responses to estimate the likelihood of alcohol-related harm. Sex-specific cut-offs improve sensitivity by reflecting different physiological tolerances.

Representative Calculations

S= ∑i=1 ri
Total score S equals the sum of responses ri. With answers 3 + 2 + 1 the tool reports S = 6.

Edge Cases & Assumptions

  • Incomplete responses prevent score calculation and visualisation.
  • Input is limited to whole-number choices; values outside 0 – 4 are rejected.
  • Sex at birth is required because metabolic differences affect thresholds.
  • The gauge clamps scores to 0 – 12 to avoid rendering anomalies.

Performance & Stability

All computations are ms-level and executed entirely client-side. The charting layer re-initialises on window resize to preserve aspect ratio without loss of precision.

Step-by-Step Guide:

The sequence below walks you from initial input to interpreting your score.

  1. Select your sex at birth in the dropdown.
  2. Click Start Assessment.
  3. Answer each question once; the progress bar shows completion status.
  4. Review your total score and risk badge on the semicircular gauge.
  5. Expand the answer recap to print or discuss results with a professional.
  6. Avoid refreshing the page before finishing; unsaved answers will reset.

FAQ:

Why only three questions?

Research shows these items capture the most predictive elements of the full ten-item AUDIT, reducing burden while preserving accuracy.

Why ask for sex at birth?

Physiological differences influence alcohol metabolism; separate cut-offs improve risk classification for men and women.

Is my data stored?

No. Answers remain in your browser’s memory and are discarded when you close or refresh the tab.

What does my score mean?

The badge colour and gauge label indicate a risk band. Higher values suggest increasing likelihood of alcohol-related harm and may warrant professional advice.

Can I redo the assessment?

Yes. Select a different option or refresh the page to start over; previous answers are not recorded or transmitted.
