Baseline past-year mood disorders included past-year major depressive disorder (MDD), dysthymia, bipolar disorders and hypomania, and baseline past-year anxiety disorders included past-year panic disorder (with or without agoraphobia), specific or social phobias and generalized anxiety disorder. All reflected diagnoses for the year preceding the Wave 1 interview, and all ruled out cases that were exclusively illness- or substance-induced. MDD also ruled out bereavement. The NESARC measured ten personality disorders (PD): antisocial (measured at Wave 1 and updated at Wave 2), avoidant, paranoid, dependent, schizoid, obsessive/compulsive and histrionic (measured exclusively at Wave 1) and borderline narcissistic and schizotypal (measured exclusively at Wave 2). As all are considered to be lifetime disorders reflecting pervasive behavioral patterns, all were treated as baseline risk factors, even those not measured until the Wave 2 interview. Because of their strong links with AUD in the literature, borderline PD and antisocial PD were considered separately from the other eight PD, which were combined into a single category.
