Impact of Event Scale – Revised (IES-R) for DSM-IV

Impact of Event Scale – Revised (IES-R), a self-report measure used to assess distress caused by traumatic events.

Resource Abstract

“The IES-R is a 22-item self-report measure (for DSM-IV) that assesses subjective distress caused by traumatic events. It is a revised version of the older version, the 15-item IES (Horowitz, Wilner, & Alvarez, 1979). The IES-R contains 7 additional items related to the hyperarousal symptoms of PTSD, which were not included in the original IES. Items correspond directly to 14 of the 17 DSM-IV symptoms of PTSD. The IES-R has not been updated to match the DSM-5, so it does not include items to full assess negative alterations in cognition and mood, for instance. Respondents are asked to identify a specific stressful life event and then indicate how much they were distressed or bothered during the past seven days by each “difficulty” listed.”
