"Health care service delivery may be challenging in the post-disaster environment and often requires coordination and cooperation among levels of government, health services programs, schools, media, and community organizations "
"The first challenge lies in identifying the correct sampling frame, which generally comprises all persons affected by the disaster. The sampling frame may be even more difficult to identify in natural disasters, when the geographic area of impact is larger and less defined."
"The second challenge lies in finding potential participants and completing interviews. Widespread displacement and communication breakdown may make it difficult to reach per- sons who have experienced the disaster, and if they can be reached, they may be consumed with recovery efforts and may not agree to participate in research . "
"Psychological first aid (PFA) has become the preferred post-disaster intervention, with three goals: Secure survivors’ safety and basic necessities (e.g., food, medical supplies, shelter), which promotes adaptive coping and problem solving; reduce acute stress by addressing post-disaster stressors and providing strategies that may limit stress reactions; and help victims obtain additional resources that may help them cope and regain feelings of control.
