title: Compatibility of current DSM-IV and proposed DSM-5 diagnostic criteria for cocaine use disorders.
abstract: OBJECTIVE
  The present study examined the compatibility of the current DSM-IV and proposed DSM-5 diagnostic criteria for cocaine use disorders (CUD) among state prison inmates, and evaluated the diagnostic utility of the proposed criteria in accounting for DSM-IV "diagnostic orphans" (i.e., individuals who meet one or two of the diagnostic criteria for substance dependence yet fail to report indications of substance abuse).
  
  
  METHODS
  Data were derived from routine clinical assessments of adult male inmates (N=6871) recently admitted to the Minnesota Department of Corrections state prison system from 2000 to 2003. An automated (i.e., computer-prompted) version of the Substance Use Disorder Diagnostic Schedule-IV (SUDDS-IV; Hoffmann & Harrison, 1995) was administered to all inmates as part of routine assessments. DSM-IV and DSM-5 criteria were coded using proposed guidelines.
  
  
  RESULTS
  The past 12-month prevalence of DSM-IV CUDs was 12.7% (Abuse, 3.8%, Dependence, 8.9%), while 11.0% met past 12-month DSM-5 criteria for a CUD (Moderate [MCUD], 1.7%; Severe [SCUD], 9.3%). When DSM-5 criteria were applied, 11.8% of the DSM-IV diagnostic orphans received a MCUD diagnosis. The vast majority of those with no diagnosis (99.6%) continued to have no diagnosis, and a similar proportion who met dependence criteria (98.4%) met SCUD criteria of the proposed DSM-5. Most of the variation in diagnostic classifications was accounted for by those with a current abuse diagnosis.
  
  
  CONCLUSIONS
  The proposed DSM-5 criteria perform similarly to DSM-IV criteria in terms of the observed past 12-month CUD prevalence and diagnostic classifications. The proposed criteria appear to account for diagnostic orphans that may warrant a diagnosis. DSM-IV abuse cases were most affected when DSM-5 criteria were applied. Additional criteria, beyond those included in the proposed DSM-5 changes, concerning use to relieve emotional stress and preoccupation with use were frequently endorsed by those with a proposed DSM-5 diagnosis.
