The AUDADIS uses 21 items to assess the 11 alcohol dependence and abuse criteria according to DSM-IV (American Psychiatric Association., 2000). As the lifetime dependence and abuse criteria were unidimensional in this sample (Shmulewitz et al., 2010), we created a quantitative measure of AUD severity by counting the number of lifetime criteria endorsed; AUD severity ranged from 0–11. Test-retest reliability of lifetime AUDADIS alcohol criterion count is excellent in general population samples (ICCs=0.86–0.89 (Hasin et al., 2007)).
