This document summarizes a proposed study that aims to examine whether thorough pre-deployment preparation and post-deployment debriefing can predict lower severity of PTSD symptoms in OEF/OIF veterans. The study would survey 3000 recent combat veterans through self-reported measures of preparedness, combat experiences, social support, and PTSD symptoms. If results show a relationship between preparation and PTSD severity, it could imply social workers design preparation interventions, and researchers conduct an experimental study to evaluate an mandated preparation program's effectiveness in preventing or reducing PTSD. Positive results may also suggest policy implications, as preparation costs may be lower than lifetime PTSD treatment costs.
