Peritraumatic distress: A review and synthesis of 15 years of research.

Abstract

Although the subjective trauma exposure criterion was removed from the DSM-5 criteria set for posttraumatic stress disorder (PTSD), emerging literature suggests that peritraumatic distress may be useful in predicting outcomes after exposure to a stressful event. We conducted a comprehensive review of the literature examining the association between peritraumatic distress and PTSD and other psychiatric outcomes. The 57 studies herein varied in both experimental design and target populations. Forty-eight studies found associations between peritraumatic distress and PTSD outcome measures, 23 found associations between peritraumatic distress and other psychiatric outcomes, and three found associations between peritraumatic distress and PTSD-related symptoms or other psychiatric outcomes after non-Criterion A stressful events by DSM-5 criteria. Peritraumatic distress is associated with PTSD symptom severity, other psychiatric symptoms, and severity of PTSD-related symptoms after exposure to non-Criterion A events, suggesting that peritraumatic distress is a risk factor for various psychiatric outcomes and furthering our understanding of the impact of subjective experience on trauma psychopathology.
