The diagnostic interview used was the NIAAA’s Alcohol Use Disorder Associated Disabilities Interview Schedule – DSM IV Version (AUDADIS-IV) (Grant et al., 2001). The AUDADIS-IV is designed to be administered by lay interviewers. Diagnoses included were: alcohol dependence, major depression (unipolar), dysthymia, panic disorder with and without agoraphobia social phobia, specific phobia, and generalized anxiety disorder. The rationale for including these disorders in the present work is that they comprise the same set of disorders in most studies evaluating the latent internalizing construct (c.f., Krueger and Markon, 2006). All diagnoses were made for the past 12 months and prior to the past 12 months (relative to the interview). By combining these two diagnostic timeframes into a single variable, we created a lifetime timeframe for each diagnosis that, in addition to the 12-month diagnoses, was used in the present work. Note that panic disorder with and without agoraphobia was counted as two separate internalizing disorders to be consistent with past studies (Krueger and Markon, 2006). Finally, good to excellent estimates of reliability were obtained based upon 10% of the sample who were re-interviewed (Grant et al., 2003b).
