The impact of DSM classification changes on the prevalence of alcohol use disorder and 'diagnostic orphans' in Lebanese college youth: Implications for epidemiological research, health practice, and policy.

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".
