Assessing the impact of disasters on helpers

This paper compares the effectiveness of the General Health Questionnaire (GHQ-30) and the Impact of Event Scale (IES) for assessing the impact of disasters on volunteers involved in the rescue work following the Armenian earthquake. The IES gave fewer zero scores and so was less likely to result in helpers being labelled symptom-free when they were not. It was conclude that IES was a more sensitive instrument and a more effective means of assessing the psychological consequences of disaster work.
