The inter-rater accordance was assessed based on all coded answers (N = 552 for past 12 months questions and N = 1,107 for lifetime), irrespective of the respondent’s treatment status and AUDs diagnosis (i.e. sub threshold cases with only one criterion included). Multiple answers per patient were possible. The two raters showed a substantial to perfect accordance as shown in Table 2.Table 2Inter-rater accordance (Kappa) between two independent raters on all answers reported.
