Reexperiencing symptoms are a key feature of posttraumatic stress disorder (PTSD). This study investigated the pattern of reexperiencing symptoms in non-PTSD posttraumatic disorders. This study recruited 1084 traumatically injured patients during hospital admission and conducted follow-up assessment 12 months later (N = 817, 75%). Twelve months after injury, 22% of patients reported a psychiatric disorder they had never experienced prior to the traumatic injury. One-third of patients with a non-PTSD disorder satisfied the PTSD reexperiencing criteria. Whereas patients with a non-PTSD disorder were more likely to experience intrusive memories, nightmares, psychological distress and physiological reactivity to reminders, only patients with PTSD were likely to experience flashback memories (OR: 11.41, 95% CI: 6.17-21.09). The only other symptom that was distinctive to PTSD was dissociative amnesia (OR: 4.50, 95% CI: 2.09-9.71). Whereas intrusive memories and reactions are common across posttraumatic disorders, flashbacks and dissociative amnesia are distinctive to PTSD.
