Abstract

The Impact of Event Scale (ES; M. J. Horowitz, N. Wilner, & W. Alvarez, 1979) is a worldwide-used self-report measure to assess the frequency of intrusive and avoidant phenomena after a variety of traumatic experiences. The purpose of this article is to assess the psychometric value of the Dutch version of the IES (D. Brom & R. J. Kleber, 1985) in several samples of individuals who had experienced various traumatic stressors. The reliability and structure of the IES were evaluated in 3 different samples (total N = 1.588). The reliability of the Dutch version of the IES was adequate across the various stressors. The construct validity was assessed by using confirmatory factor analyses. Outcomes revealed a robust structure over the various samples, generally supporting the composition of the original IES.
