Study Design

Prospective cohort 

Time Period

2002 - present




Time 1: 1,649 participants
Time 2: 1,340 participants
Time 3: 1,202 participants

Response Rate

Time 1: 37.6%
Time 2: 81.3%
Time 3: 72.9%

Recruitment Method

Researchers compiled a list of Veterans who either separated from active duty after serving in OEF/OIF/OND or completed at least one Reserve/Guard deployment in support of OEF/OIF/OND. The study aimed to enroll at least 1,200 Veterans with a recent diagnosis of PTSD in the VA medical record and 400 Veterans without such a diagnosis. Veterans with PTSD diagnosis were randomly selected at a rate of 3:1 relative to a comparison group of Veterans, who were also randomly selected. Potential participants were invited to participate via phone, and those providing informed consent were enrolled in the study.
