This analysis is based on a subsample of respondents who had consumed at least one drink between the Wave 1 and Wave 2 interviews and who reported their age at first drink (n=22,316). Analyses of the incidence of AUD and specific AUD criteria were restricted to individuals who were at risk for first incidence of those disorders or criteria. The risk groups for alcohol abuse and dependence comprised individuals who had not met the criteria for those disorders prior to the Wave 1 interview. Similarly, the risk groups for specific AUD criteria comprised individuals who had not endorsed the specific criteria in question prior to Wave 1. Incidence for specific dependence criteria did not require a positive diagnosis for dependence.
