Design
Descriptive mixed methods study
Descriptive qualitative
Explorative qualitative

Focus
To describe how disaster radio was used to communicate vital and health-related information and after the Haiyan typhoon.
To describe expereinces and needs from being in a natural disaster, and the impact of disaster radio from the affected individuals´perspective.
To explore experiences from being deployed as a health profssional during a natural diaster.
To describe health consequences of a natural diaster, and potential effects of disaster radio on health in a long term perspective.

4. The content of broadcast
Messages changed over time
Encourangement messages were the most frequent broadcast
Health related messages comprised a minor part of all messages and there were gaps in the broadcast

7. Conclusions and recommendations
Disaster radio seems to be a useful tool to help provide evidence based psychosocial support, and to promote health in the aftermath of a disaster.
Both the information and the music were contributing factors for recovery.
It is assumed that further integration and coordination between health professionals, crisis communication experts and radio broadcasting personnel should improve and enhance the use of radio as a positive health intervention response.
Research studies designed to find strategies for supporting social needs are strongly needed. Additionally, studies on short and long term health effects, in both an individual and a community resilience perspective, would strengthen the evidence base for using radio in the early stages after a disaster.
