Moye J, Kaiser AP, Cook J, et al. - Researchers sought to report on the prevalence, characteristics, and comorbidities of subthreshold and full posttraumatic stress disorder (PTSD) in a nationally representative sample of older US military veterans.

• US veterans aged 60 and older (n = 3,001; mean age = 73.2) who participated in the National Health and Resilience in Veterans Study (NHRVS) were surveyed in this nationally representative web-based survey.

• Exposure to one or more potentially traumatic events was recorded in the vast majority of the sample (n = 2,821; 92.7%); 262 (9.6%) of these screened positive for subthreshold and 68 (1.9%) screened positive for full PTSD.

• Female veterans and veterans who use VA as their primary healthcare showed significantly higher prevalence of subthreshold and full PTSD.

• Relative to the no/minimal PTSD symptom group, subthreshold and full PTSD groups endorsed more adverse childhood experiences and total traumas.

• Veterans with subthreshold and full PTSD more frequently screened positive for depression, substance use disorders, suicide attempts, non-suicidal self-injury, and suicidal ideation, and had lower mental, cognitive, and physical functioning.
