Summary: The IES (Horowitz, Wilner, & Alvarez, 1979) has probably been the most widely used "quick & dirty" measure of post-traumatic stress, with a focus on the classic avoidance and intrusion symptoms. Dyregrov and Yule (1995) have validated a subset of 8 items for use with children and adolescents. Both versions are psychometrically sound. The content shown here is correct, but the printed format is nicer than this one. Also, the frequency boxes should be blank, with the scoring done later (I couldn't figure out how to program blank boxes).
