Because descriptive analyses suggested that patients who met criteria for DSM-5 alone may differ on the burden of negative consequences due to drinking, mental health and drug use conditions, and readiness to change from patients meeting criteria for neither DSM-IV nor DSM-5 AUD, or both DSM-IV and DSM-5 AUD, we performed post hoc statistical tests to evaluate whether differences across the mutually exclusive diagnostic groups were statistically significant. For the purposes of these post hoc analyses, the diagnostic group that included the lone subject who met DSM-IV criteria for AUD alone, was excluded resulting in a 3-way comparison. These analyses revealed that all three measures differed significantly across the 3 groups (p < 0.001) (Table 3b).
