Objectives: This study investigated the prevalence of trauma and posttraumatic stress disorder (PTSD) in patients with schizophrenia and compared the clinical outcomes in the PTSD group and the non-PTSD group.
Methods: Among 38 patients, a total of 35 schizophrenic patients completed the Positive and Negative Syndrome Scale (PANSS), Life Stressor Checklist-Revised (LSCL-R), and Clinician-Administered PTSD Scale (CAPS).
Results: Thirty three patients (94.2%) had at least one trauma and average 3.9 traumatic events in their life time. There were 12 patients (34.3%) who were diagnosed with PTSD. There were no differences of sociodemographic, duration of illness, number of admission, and duration of admission between the PTSD and non-PTSD groups. After one year treatment, the non-PTSD group had significantly improved in PANSS positive, negative, and general psychopathology scale. However, the PTSD group demonstrated no significant changes in PANSS negative and general psychopathology scale.
Conclusion: In this study, there were high rate of prevalence of trauma and PTSD in patients with schizophrenia. PTSD had negative effects on clinical outcomes in patients with schizophrenia. Careful trauma-focused approach is necessary within this population.
