Does writing reduce posttraumatic stress disorder symptoms?

To see if writing about their trauma lessened PTSD and related symptoms, 57 undergraduates, previously screened for traumatic experiences, wrote for 15 minutes on 4 days across 2 weeks about either their trauma or a trivial topic. They reported PTSD, impact, suicide ideas, dissociation, and depression pre-, post-, and at 6-week follow-up testing. Trauma and trivial writers were not different. Surprisingly, at follow-up everyone reported less severe PTSD symptoms, impact, and dissociation, and fewer health visits, but about the same suicidal ideation and depression. On PTSD symptoms and impact, the pattern of improvement was different: Those writing about trauma got worse at posttesting, but improved to better than their initial state by follow-up. Those writing about a trivial topic got better by posttesting, and held that position at follow-up. In this project, writing seemed to reduce PTSD symptoms regardless of whether it concerned the trauma or what they ate for lunch.
