Psychiatric diagnostic measures were gathered from the Alcohol Use Disorder and Associated Disabilities Interview Schedule–DSM-IV Version (AUDADIS-IV) (Grant et al., 2001, 2004). The high reliability and validity of the AUDADIS substance use disorder diagnoses are well documented (e.g., Hasin et al., 1997). Psychiatric disorders included DSM-IV [American Psychiatric Association (APA), 2000] (a) cannabis use disorders (CUD; i.e., cannabis abuse and dependence); (b) nicotine dependence (ND); (c) major depression; (d) bipolar disorder (i.e., bipolar I and II); (e) anxiety disorders (i.e., panic disorder, social anxiety disorder, specific phobias, generalized anxiety disorder, posttraumatic stress disorder); (f) personality disorders; and (g) attention-deficit/hyperactivity disorder. Antisocial personality disorder is common among individuals with substance use disorders (Compton et al., 2005), and because the presence of it could have inflated prevalence estimates of any personality disorder and Cluster B personality disorders, we examined this disorder separately.
