It should be noted that despite efforts to ensure comparability across the NLAES and NESARC versions of the AUDADIS-IV, there were some changes that occurred that could have potentially affected observed prevalence estimates. The NLAES and NESARC versions of the AUDADIS–IV included “duration criteria” of both the alcohol abuse and dependence diagnoses (see Grant et al., 2004). As described by Grant et al. (2004), “duration criteria relate to specific abuse and dependence criteria, define the repetitiveness with which these diagnostic criteria must occur in order to be positive, and are operationalized by means of qualifiers, such as ‘recurrent,’ ‘often,’ and ‘persistent.’” (p. 226). The duration criteria are not associated with all abuse and dependence criteria and differed between the NESARC and NLAES studies (see Table 1 for abuse; dependence not shown). The duration criteria were operationalized in NLAES by asking respondents if a symptom item had happened more than once in a follow-up question. However, in NESARC, duration criteria were directly embedded into the symptom questions (e.g., “more than once” drive a vehicle while drinking; see Table 1, Grant et
