This study included 102 patients with schizophrenia, bipolar disorder, and schizoaffective disorder, according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Epidemiological and clinical data were collected using the Brief Psychiatric Rating Scale and Traumatic Life Events and Distressing Event questionnaires. We found a high number of traumatic experiences, and 15.1% of the patients met all criteria for PTSD. We found no differences based on diagnosis or sex, although there was a nonsignificant trend toward greater PTSD comorbidity in women. Among patients with serious mental illness and PTSD, 64.3% had made some attempt at suicide at some point in life, compared with 37.4% of patients without PTSD. *Mental Health Department and †Clinical Epidemiology Department, Vic Hospital Consortium, Catalonia, Spain.
