Diagnostic and statistical manual of mental disorders, fifth edition, and the impact of events scale-revised

摘要

We read with great interest the article by Bienvenu et al1 in a recent issue of CHEST (July 2013) and would like to compliment them on the development and validation of the Impact of Events Scale-Revised (IES-R) for patients with posttraumatic stress disorder (PTSD) after acute lung injury. Psychiatric nosology and diagnostic classification systems are always dynamic and in a state of flux. The authors developed the screening questionnaire and validated it against the Clinician-Administered PTSD Scale (CAPS), which is based on Diagnostic and Statistical Manual of Mental Disorders (DSM), fourth edition, diagnostic criteria. However, the recently introduced fifth edition (DSM-5) has revised the conceptualization as well as the diagnostic criteria for PTSD, which has definite implications for the screening instrument proposed in the study.
