To validate the diagnostic accuracy of AUDIT and AUDIT-C for identifying alcohol use disorders in the Danish population.
Cross-sectional study with 17,959 participants aged 25+ years completing an anonymous online alcohol habits questionnaire.
Evaluation of demographics, AUDIT, and self-reported ICD-10 alcohol dependence criteria.
Determination of optimal cut-off scores and analysis of receiver operating characteristics (AUC).
AUDIT showed good discrimination for hazardous use (AUC=0.89) and dependence (AUC=0.96), but poor for harmful use (AUC=0.61).
AUDIT-C demonstrated good sensitivity for hazardous use (AUC=0.92) and dependence (AUC=0.92), with lower thresholds recommended for women and older adults.
High internal consistency for AUDIT (α = 0.83) and lower for AUDIT-C (α = 0.61).
