abstract="BACKGROUND: There is a need for empirical studies assessing the psychometric  properties of self-reported alcohol use as measures of excessive chronic drinking  (ECD) compared to those of objective measures, such as ethyl glucuronide (EtG). <br><br>OBJECTIVES: To test the quality of self-reported measures of alcohol use and of  risky single-occasion drinking (RSOD) to detect ECD assessed by EtG. <br><br>METHODS: A  total of 227 samples of hair from young Swiss men were used for the determination of  EtG. Self-reported measures of alcohol use (previous twelve-month and previous-week  alcohol use) and RSOD were assessed. Using EtG (<30 pg/mg) as the gold standard of  ECD assessment, the sensitivity and specificity were computed, and the AUROC were  compared for alcohol use measures and RSOD. Logistic regressions were used to test  the contribution of RSOD to the understanding of ECD after controlling for alcohol  use. <br><br>RESULTS: A total of 23.3% of participants presented with ECD. Previous  twelve-month alcohol use with a cut-off of >15 drinks per week (sensitivity = 75.5%,  specificity = 78.7%) and weekly RSOD (sensitivity = 75.5%, specificity = 70.1%)  yielded acceptable psychometric properties. No cut-off for previous-week alcohol use  gave acceptable results. In the multivariate logistic regression, after controlling  for the previous twelve months of alcohol use, RSOD was still significantly  associated with EtG (p =.016). <br><br>CONCLUSION: Self-reported measures of the previous  twelve months of alcohol use and RSOD were acceptable measures of ECD for  population-based screening. Self-reported RSOD appeared to be an interesting  screening measure, in addition to the previous twelve months of alcohol use, to  understand ECD among young people.<p /> <p>Language: en</p>",
