Universal disaster services are used for children in general populations without consideration of their disaster exposures, experiences, or reactions. Universal disaster services include screening and case finding as well as preparedness and post event preventive interventions. Universal services are typically administered in a group format in settings where children naturally congregate, such as schools.
