Abstract
Objective: To investigate the relationship between childhood trauma, post-traumatic stress symptoms due to the experience of childhood trauma, and post-traumatic stress symptoms due to the experience of psychosis. Method: The current study assessed childhood trauma and post-traumatic stress disorder (PTSD) symptoms as a result of both childhood trauma and psychosis using the Impact of Events Scale - Revised, in a group of 36 people with first-episode psychosis. Results: Reported rates of clinical level post-psychotic PTSD symptoms, childhood trauma and childhood trauma-related clinical level PTSD symptoms were 47% (95% CI 31–64%), 64% (95% CI 48–80%) and 39% (95% CI 23–55%), respectively. Reporting childhood trauma increased the risk of developing post-psychosis PTSD 27-fold (95% CI 2.96–253.80, p = 0.01). Having childhood trauma-related PTSD increased the risk of developing post-psychosis PTSD 20-fold (95% CI 3.38–123.25, p = 0.01). These risks were not explained by illness factors such as duration of untreated psychosis, age of onset or severity of psychotic symptoms. Those without post-psychotic PTSD symptoms at clinical levels were unlikely to report childhood trauma (6%; 95% CI 3–8%). Conclusions: These results suggest the cognitive, social and biological consequences of childhood trauma can prevent effective recovery from the trauma of acute first-episode psychosis resulting in post-psychotic PTSD. Treatment strategies for post-psychotic PTSD must address childhood trauma and related PTSD.
