Notably, 2898 respondents (82.5%) reported intrusive memories, 2378 (67.7%) reported nightmares, and 2004 (57.1%) reported flashbacks 3190 (95.7%) reported either intrusive memories, nightmares, or flashbacks.Īccepted for Publication: October 14, 2022. The following most common patterns comprised satisfying each of the B cluster (reexperiencing) and C (active avoidance) symptoms, with different symptoms being endorsed in the D (alterations in mood and cognition) and E (arousal) clusters. The most salient symptom pattern for PTSD was global endorsement of all symptoms (13.4%) ( Table). That is, 1935 participants (55.1%) who met criteria for PTSD had a unique pattern of symptoms, 8.2% occurred across 2 people, and 2.9% occurred across 3 people ( Figure). Of the 3511 participants with a PTSD diagnosis, there were 2181 different patterns of symptoms 1935 (88.7%) occurred only once. Of the 3511 participants with a PTSD diagnosis on at least 1 assessment, analyses focused on the initial PTSD diagnosis received by each participant. Of these, 4843 sets of responses yielded a diagnosis of PTSD, derived from 3511 participants. Of 10 965 participants (mean age, 31.2 years predominantly male and of White race ) across the 4 data sets, there were 17 260 sets of complete PCL data. This study followed the RECORD reporting guideline. 5 Endorsement of each symptom was defined as being at least moderate (score ≥2 on a 0-4 rating). 4 The PCL-C is validated relative to structured clinical interview in Army STARRS. Following informed consent, participants completed a traumatic events checklist, and then 30-day PTSD symptoms were assessed using the PTSD Checklist–Civilian Version (PCL-C) that was modified to measure the DSM-5 items. Ethical approval was provided by the Humans Subjects Committees of the Uniformed Services University of the Health Sciences. It also used data from the Army STARRS Longitudinal Study, which comprised further waves of Army STARSS cohorts. ![]() This analysis focused on the Pre-Post Deployment Study (PPDS) because it measured DSM-5 diagnoses of PTSD and relied on data collected at 3 and 12 months after troops returned from Afghanistan. Data were collected between October 2012 and June 2019 and analyzed from April to August 2022. ![]() The sample was derived from multiple cohorts from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS 3) and analyzed using R version 4.2 (R Foundation for Statistical Computing) and SPSS version 28 (IBM).
