In NESARC, we diagnosed hazardous use using three items: more than once driving a vehicle while drinking, endorsed by 1,584 individuals;more than once driving a vehicle after drinking too much, endorsed by 1,272 individuals;get into situations which increased chances of getting hurt while drinking or after drinking, endorsed by 499 individuals. Item (c) is most comparable to the item used by Mewton et al (recurrent use in physically dangerous situations). Thus, we re-defined hazardous use using this single item and were able to approximate the prevalence of hazardous use reported in NSMHWB (2.1%) with NESARC (3.2%). Correspondingly, this recoding reduced the past 12 month prevalence of hierarchical abuse in the full sample to 1.3%, the latter being highly comparable to the report by Mewton et al. This produced a reduced DSM-IV abuse/ dependence prevalence of 5.7%, a DSM-5 AUDs prevalence of 9.4% and a corresponding increase in prevalence of AUDs from DSM-IV to DSM-5 of 65%, all of which reconcile well with Mewton et al.
