Scott on "Comparisons of Memories for Traumatic Events and Other Experiences".In this study undergraduate college women were questioned using the Traumatic Stress Survey to identify a potentially traumatic event in their lives, such as child abuse, experiencing a natural disaster or other types of victimization.
