 Within 3-7 days prior to the projected date of discharge, the investigator or designee will administer the Impact of Events Scale-Revised IES-R. The IES-R instrument will be administered by the investigator or designee only. The IES-R evaluates subjective distress caused by traumatic events and will be used to assess manifestations of PTSD. It is not diagnostic but possesses excellent reliability and validity for manifestations of PTSD. The IES-R has three subscales eight items on intrusion, eight items on avoidance, and six items on hyperarousal. Each item is scored on a four point scale: 0 not at all, 1 a little bit, 2 moderately often, 3 quite a bit, and 4 extremely often. The total score of each subscale may be averaged and a cumulative score of 30 is indicative of the presence of PTSD.
