Harned and colleagues' conclusion that frequency, intent, and lethality of suicide attempts are the same for individuals with borderline personality disorder with and without PTSD is inconsistent with recent work. Cougle et al. (2), using the U.S. National Comorbidity Survey Replication data (N=5,692), demonstrated that PTSD is associated with suicide attempts, even after adjusting for the effects of borderline personality disorder. We extended these findings using the National Epidemiologic Survey on Alcohol and Related Conditions (N=34,653), by showing that PTSD is associated with suicide attempts after adjustment for all sociodemographic factors and axis II disorders (3). Pagura et al. (4) were the first to examine comorbidity of PTSD and borderline personality disorder in a large nationally representative sample by comparing individuals with PTSD alone (N=1,820), borderline personality disorder alone (N=1290), and comorbid PTSD and borderline personality disorder (N=643). This study found that individuals with comorbid PTSD and borderline personality disorder had greater odds of lifetime suicide attempt compared to individuals with either condition alone (4).
