Conclusions: The prevalence of lifetime PTSD in US military veterans (9.4%) is slightly higher than 2016 estimates (6.9%-8.1%). Direct and indirect PTEs are prevalent in US military veterans, with only direct PTEs associated with higher conditional probability of past-month PTSD and greater functional impairment.
