The lifetime prevalence of psychiatric disorders by DUI category is presented in Table 3. Rates of lifetime disorder were high across all DUI categories, compared with national prevalence surveys (Kessler et al., 2005; Kessler et al.,1994), and only a few differences between categories were observed. Men with 3+ DUIs were more likely to meet criteria for any disorder than men with 1 or 2 DUIs; among women this difference was not statistically significant. Rates of lifetime depression were higher among women with 2 or 3+ DUIs than women with 1 DUI only. Men with 3+ DUIs had higher rates of conduct and antisocial personality disorders than men with 1 or 2 DUIs. The most striking gender difference was for antisocial personality disorder, where women with 1 or 2 DUIs diverged more markedly from women with none than did similar men. Of the 1559 individuals who were assessed for posttraumatic stress disorder (PTSD; assessed at Phase 2 interview only), 43% endorsed a PTSD-qualifying event (men: 47%, women: 39%). Rates of event endorsement and PTSD were similar across all DUI categories.
