title: Posttraumatic stress disorder symptoms related to psychosis and acute involuntary hospitalization in schizophrenic and delusional patients.
abstract: The aims of this study were: a) to assess the prevalence of posttraumatic stress disorder (PTSD) after an acute psychotic episode in schizophrenic and delusional patients, b) to explore which psychotic symptoms and aspects of treatment were associated with traumatization, and c) to compare the extent of the traumatic impact of psychosis and involuntary hospitalization. Forty-six schizophrenic and delusional patients were assessed with the Positive and Negative Syndrome Scale (PANSS), the Impact of Event Scale-Revised (IES-R), and the Clinician-Administered PTSD Scale (CAPS) at weeks 1 and 8 after acute psychiatric admission. Traumatic symptoms related to psychosis and coercive measures were scored separately. The prevalence of PTSD was found to be 11%. Sixty-nine percent of traumatic symptoms were related to psychosis and 24% to hospitalization. High PANSS score at week 8 was the strongest risk factor for the development of PTSD. Particularly positive and depressive/anxious symptomatology were associated with psychosis-related traumatic symptoms at both weeks 1 and 8. These data suggest that, in general, schizophrenic and delusional symptoms are more traumatic than the coercive measures used to control them.
