NIH Repository of COVID-19 Research Tools
"This website provides access to COVID-19 related data collection tools (CRFs, DCFs, instruments, surveys, questionnaires) that are currently in use. We hope that investigators will consider choosing from these tools rather than developing new ones. The source of each instrument has been verified and contact information is provided in case additional information is needed. We are also striving to provide access to study protocols/study designs and data dictionaries to enhance timeliness for end use, as well as data interoperability and harmonization. Please note, these data collection tools cannot be considered broadly validated and investigators are encouraged to perform validation studies."
