Duration of Exposure and the Dose-Response Model of PTSD JOURNAL OF INTERPERSONAL VIOLENCE Kaysen, D., Rosen, G., Bowman, M., Resick, P. A. 2010; 25 (1): 63–74

Abstract

A dose-response model underlies posttraumatic stress disorder (PTSD) and posits a relationship between event magnitude and clinical outcome. The present study examines whether one index of event magnitude--duration of exposure--contributes to risk of PTSD among female victims of sexual assault. Findings support a small but significant contribution of event duration to clinical status in the immediate aftermath of trauma but not at 3-month follow-up. The opposite pattern is obtained for subjective appraisals of threat. These findings add to a growing literature that suggests that a simple application of the dose-response model to objective event characteristics may be insufficient to explain the risk of PTSD.
