The Impact of DSM Classification Changes on the Prevalence of Alcohol Use Disorder and 'Diagnostic Orphans' in Lebanese College Youth

​​​Studies comparing prevalence of alcohol use disorder (AUD) using DSM-IV and DSM-5 diagnostic criteria in college students are limited. Researchers from AUB' Faculty of Health Sciences and University of Iowa conducted a study to examine the changes in AUD prevalence estimates using DSM-IV versus DSM-5 and characterizes the profile of DSM-5 "diagnostic orphans."​

The study found that DSM-IV abuse/dependence prevalence rate was higher than DSM-5 AUD prevalence mainly due to the high percentage of students who engaged in "hazardous use". The DO screen might capture a young person in transition between non-drinking/occasional drinking to drinking frequently/developing an AUD. The prevention, identification, and management of DOs may be critical components of a national alcohol harm-reduction policy.
