Disasters are often associated with structural, economic, and population disruptions which may lead to short and long-term mental health consequences in adults and children. Although there are a number of rapid assessment and survey research instruments that have been used to assess post-disaster mental health status, there is no single compendium that has systematically collected, validated, and catalogued such behavioral measures. In response to the Request for Proposals from the Council of State and Territorial Epidemiologists, we propose to collaboratively develop a standardized validated toolkit of disaster-related mental health measures. We firmly believe that such a catalogue can support informed decision-making and programmatic strategies for public mental health interventions following catastrophic events.
