Multicenter Study
A multisite study of the capacity of acute stress disorder diagnosis to predict posttraumatic stress disorder.
Previous studies investigating the relationship between acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) have reported mixed findings and have been flawed by small sample sizes and single sites. This study addresses these limitations by conducting a large-scale and multisite study to evaluate the extent to which ASD predicts subsequent PTSD. ⋯ The majority of people who develop PTSD do not initially meet criteria for ASD. These data challenge the proposition that the ASD diagnosis is an adequate tool to predict chronic PTSD.
