The authors surveyed hospital and public health workers to assess their willingness to respond to a pandemic influenza emergency scenario and a radiological 'dirty' bomb scenario. They found that respondents that felt psychologically prepared were more willing to respond, and self-reported willingness to respond was influenced by perceived self-efficacy and perceived family preparedness.
