This document presents a two-part monograph developed to focus attention on emergency worker needs. It is designed to aid the paid and volunteer workers who respond to major disasters and should be useful to all agencies engaged in disaster relief operations; to regional, state, and local emergency planners; and to private charitable organizations involved in disaster relief. The monograph should also serve as a resource to mental health service providers planning a comprehensive mental health response to disasters. Part I, "Stress and Mental Health Interventions in Three Major Disasters" (Don M. Hartsough), discusses in detail different sources of stress for disaster workers and their potential effects. Preventive and treatment strategies are outlined. Part II, "Helping the Helpers: A Training Manual" (Diane Garaventa Myers), presents a detailed course designed for mental health trainers to use in helping emergency workers anticipate and prevent stress, and to learn how to get help once they experience stress-related problems. Suggestions are given for developing collaborative relationships between emergency organizations and mental health agencies. A list of relevant audiovisual and printed materials is appended. (NB)
