CITF Questionnaire 1 Harmonization Protocol
The objective of the CITF Questionnaire 1 Harmonization Protocol is to provide harmonized background information on participants, COVID-19 testing history, and COVID-19 vaccination history across contributing studies at the initial COVID pandemic data collection event. The data come from baseline or cross-sectional questionnaires or medical chart review abstracted by study personnel. The harmonized datasets allow for analysis of associations between sociodemographic risk factors, COVID-19 history, and non-pharmaceutical public health measures. The records can be linked to other harmonized datasets in the CITF initiative to enable integrated analyses across protocols.
The variables in this protocol include sociodemographic characteristics, potential COVID risk factors, and history of COVID-19 infection.

Information Content
The objective of the CITF Questionnaire 1 Harmonization Protocol is to provide background information on study participants from the initial COVID pandemic data collection event, harmonized across contributing studies. The data come from baseline or cross-sectional questionnaires or medical chart review abstracted by study personnel. The harmonized datasets allow for analysis of associations between sociodemographic risk factors, COVID-19 history, and non-pharmaceutical public health measures. The records can be linked to other harmonized datasets in the CITF initiative to enable integrated analyses across protocols.
The variables in this protocol include sociodemographic characteristics, potential COVID risk factors, and history of COVID-19 infection.

Harmonization
- Complete - study-specific variable is the same as DataSchema variable (status detail = identical) or needs transformation to generate DataSchema variable (status detail = compatible)
- Partial - categorical study-specific variable (status detail = proximate) or other types (status detail = tentative) could generate DataSchema variable but with loss of information
- Impossible - study does not collect DataSchema variable (status detail = unavailable) or cannot be used to generate DataSchema variable (status detail = incompatible)
- Not Applicable - harmonization status is not relevant
- Undetermined - harmonization status not determined
