Purpose: Alcohol use disorders have been characterized with quite similar criteria in ICD-10 and DSM-IV. In DSM-5, the distinction between alcohol abuse and dependence has been given up to propose a single unidimensional diagnosis of alcohol use disorders. The current draft ICD-11 criteria however, keep alcohol dependence as diagnosis. It is characterized by three core criteria: 1. A strong internal drive to use alcohol, manifested by impaired ability to control use, 2. increasing priority given to alcohol use over other activities, and persistence of use despite harm and adverse consequence, and 3. tolerance and withdrawal symptoms. Secondary data analyses will be presented to evaluate different algorithms and thresholds of the current draft ICD-11 criteria for alcohol dependence. Methods: Data from a general population study (total n= 4,075) and from primary care samples (general hospital and general practices; n=643 fulfilling at least one DSM-5 criterion) will be used for secondary data analysis. Results: Different algorithms referring to a nomothetic (all features of one clinical criterion have to be fulfilled) and a polythetic (one or a specific number of features of one clinical criterion has/have to be fulfilled) approach are compared to each other. In addition, different thresholds with respect to the number of criteria indicative of the disorder will be analysed. The different algorithms and thresholds will be evaluated based on the concordance with ICD-10, DSM-IV, DSM-5 and the respective prevalence rates. Conclusion: Findings provide guidance for the classification of alcohol dependence in ICD-11.
