Alcohol consumption in high school adolescents: frequency of use and dimensional structure of associated problems.

The goal of this paper is to present data regarding the occurrence of alcohol consumption and the relative prevalences and the factorial structure of DSM-IV symptoms of alcohol abuse/dependence in a sample of 1507 older (14-18 years) community adolescents. Participants were diagnostically assessed at two time points, approximately 1 year apart. Three-quarters of the sample had tried alcohol. Boys in general had greater usual frequency and quantity of alcohol consumption than girls and began drinking at an earlier age; girls with a diagnosis of alcohol abuse/dependence had a significantly earlier mean age of alcohol disorder onset and were more likely to have a relapse of alcohol disorder. However, gender differences in symptom prevalence were non-significant. Seventeen per cent of the sample had at least one alcohol abuse/dependence symptom. The most frequent symptoms included reduced activities because of alcohol use, consumed more than intended, and tolerance. Eight of the 11 symptoms made a unique contribution to the prediction of diagnosis in a multiple logistic regression analysis. Components analysis supported the general division of symptoms into the categories of abuse and dependence.
