Scaling Properties of the Combined ICD-10 Dependence and Harms Criteria and Comparisons With DSM-5 Alcohol Use Disorder Criteria Among Patients in the Emergency Department

Objective:The Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV), and the International Statistical Classification of Diseases and Related Health Problems, 10th Edition (ICD-10), alcohol use disorders (AUDs) classifications offer competing and somewhat overlapping diagnostic tools for assessing alcohol dependence and harms/abuse.

Although much psychometric work has been done studying DSM-IV criteria, efforts toward the ICD-11 have been less prevalent.Method:Data from 3,191 drinkers in seven emergency department sites in four countries (United States, Mexico, Argentina, and Poland) were used to study the psychometric properties of the combined ICD-10 dependence and harms criteria. Comparisons with the proposed set of DSM-5 criteria and diagnostic thresholds are also included.Results:Item response theory analyses of the combined ICD-10 dependence and harms criteria suggested a singl...
