Abstract:
This study explored dimensionality and rank-order severity of the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) alcohol use disorder (AUD) criteria among adults 50+ years old. Secondary analysis was performed on data from individuals 50+ (N = 3,412) from the 2009 National Survey of Drug Use and Health. Confirmatory factor analyses (CFA) and item response theory (IRT) analyses were performed on the 11 AUD criteria. DSM-IV and DSM fifth edition (DSM-5) classifications were compared. CFA revealed a one-factor model. IRT analyses revealed that AUD criteria identify only severe cases of AUD. Overall, 5.8% met criteria for a DSM-IV AUD; 7.5% met criteria for DSM-5 AUD.
