Background: The purpose of this study was to investigate the psychiatric comorbidity rates, severity of psychological disorders, and factors predicting cormorbidities in disaster victims with PTSD.
Methods: Three hundred and fifty-three disaster victims who scored over the threshold to be classified as potentially meeting criteria for PTSD were selected data from Long-term Investigation of Disaster Victims and Development of Life-Friendly Relief Policy Technology in South Korea.
Results: First, total comorbidity rate of depression or anxiety disorder only and both depression and anxiety disorder in individuals with PTSD was found in 37.4%. Second, the severity of psychological disorders increased with the number of comorbid disorders.
