[Validation of a questionnaire to evaluate alcohol related behaviours in excessive drinkers]

The excessive consumption of alcohol and alcoholic drinks is an habit with high socioeconomic costs and a strong impact on health that requires research aiming at establishing adequate political options concerning trends, observed behaviours and consumption.

Excessive alcohol consumers.

Cross-sectional study based on a questionnaire and biochemical markers assessment, aiming to validate an instrument to evaluate alcohol consumption and alcohol-related behaviours.

A correlation between age at first contact with alcohol and the beginning of the regular consumption(r = 0,72; p < 0,001) was found. Alcohol consumption in the last 12 months correlated with - % CDT (r = 0,54; p < 0,001) and with γ-GT (r = 0,47; p < 0,001).

The validity of the instrument developed to evaluate alcohol-related behaviours is acceptable and therefore it may be used to establish hierarchy between levels of alcohol consumption defined by categories of ingestion and negative consequences.
