We created two dichotomous variables from the W2 data indicating whether or not respondents met criteria for past-year DSM-5 AUD or past-year DSM-IV internalizing disorder (mood or anxiety disorders including major depression, bipolar I and II, dysthymia, social phobia, specific phobia, generalized anxiety disorder, and post-traumatic stress disorder). The individual psychiatric disorders have test-retest reliabilities (kappa) that range from 0.40 to 0.77 (Grant et al., 2003; Ruan et al., 2008). We note that being positive for past-year AUD was an indicator of AUD persistence (versus AUD remittance) owing to the use of alcohol-affected status in the prior two years to define the analytic sample. In contrast, being positive for past-year internalizing disorder could indicate incident disorder or persistent disorder (versus remittance or remaining unaffected).
