An assessment of the compatibility of DSM-IV and proposed DSM-5 criteria in the diagnosis of cannabis use disorders.

The current study used an automated version of the substance use disorder diagnostic schedule-IV (SUDDS-IV) to assess DSM-IV (fourth edition of the Diagnostic and statistical manual of mental disorders) and two sets of proposed DSM-5 (fifth edition of the Diagnostic and statistical manual of mental disorders) cannabis use disorder criteria among adult prison inmates in the Minnesota Department of Corrections state prison system from 2000 to 2003. Initially proposed DSM-5 criteria had only two diagnostic designations (moderate and severe). A subsequent revision added a mild designation and required a greater number of positive findings for the severe diagnosis.
