Based on their DSM-IV and DSM-5 diagnoses, lifetime alcohol-using individuals could be classified into four groups, as shown in Tables 3A and 3B. The largest group consisted of those who were stably unaffected and were neither diagnosed with DSM-IV nor with DSM-5 AUDs, followed by those who met criteria for AUDs using both DSM-IV and DSM-5 schemes (i.e. stably affected). These two groups showed stability while the two smaller groups represent diagnostic switching between DSM-IV and DSM-5. Table 3A and 3B summarize selected socio-demographic, drinking and psychiatric characteristics of those in these four groups. In Table 3A, we present the prevalence of individual DSM-5 criteria (and also DSM-IV legal problems) across the four groups. Of the 608 individuals who switched from “Affected” to “Unaffected”, 96.5% reported hazardous use (with 581 only reporting this criterion). A majority of these individuals (92.7%) endorsed drinking and driving. A larger number (N=989) of individuals switched from “Unaffected” to “Affected” (i.e. from no DSM-IV to a DSM-5 diagnosis). These individuals met criteria for DSM-5 moderate AUD, primarily due to the endorsement of 2 DSM-IV dependence
