Factor structure of the Alcohol Use Disorders Identification Test (AUDIT) for men and women in different age groups.

OBJECTIVE: Our main aim was to investigate the factor structure of the Alcohol Use Disorders Identification Test (AUDIT) in a Finnish population sample. METHOD: The AUDIT was completed by 3,125 men (mean age = 26.2 years) and 6,006 women (mean age = 26.1 years). RESULTS: At a cutoff score of 8 or more, 49.8% of the men and 23.9% of the women would be identified as potentially engaged in excessive alcohol use. Exploratory factor analyses suggested a two-factor solution for both men and women. However, the factor structure was not invariant between men and women or in the different age groups among men. CONCLUSIONS: This is one of the largest known general population studies on alcohol use in recent years in Finland. The findings support a two-factor solution, and it is suggested that the AUDIT cutoff scores should be tailored according to age, gender, and drinking culture.
