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

Unlabelled: 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.

Objectives: To validate an instrument to evaluate the consumption of the different kinds of alcoholic drinks and alcohol-related behaviours; to assess the determinants of alcoholic drinks consumption.

Type Of Study: Validation study of an instrument to assess alcohol-related behaviours.

Place: Coimbra.

Population: Excessive alcohol consumers.

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

Results: 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).

Conclusions: 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.
