Abstract

The present study used data from the Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (n = 34,653) to examine lifetime Axis I psychiatric comorbidity of posttraumatic stress disorder (PTSD) in a nationally representative sample of U.S. adults. Lifetime prevalences ± standard errors of PTSD and partial PTSD were 6.4% ± 0.18 and 6.6% ± 0.18, respectively. Rates of PTSD and partial PTSD were higher among women (8.6% ± 0.26 and 8.6% ± 0.26) than men (4.1% ± 0.19 and 4.5% ± 0.21). Respondents with both PTSD and partial PTSD most commonly reported unexpected death of someone close, serious illness or injury to someone close, and sexual assault as their worst stressful experiences. PTSD and partial PTSD were associated with elevated lifetime rates of mood, anxiety, and substance use disorders, and suicide attempts. Respondents with partial PTSD generally had intermediate odds of comorbid Axis I disorders and psychosocial impairment relative to trauma controls and full PTSD.
