The goal of this toolkit is to provide a set of standardized quantitative and qualitative assessments to harmonize data collection efforts and facilitate comparisons of the impact of the novel coronavirus (COVID-19), and promote collaborations across research efforts. This is intended to be a dynamic resource that will evolve as the epidemic does. These modules were created with a broad sample in mind. The goal was to develop a set of modules that could be applied to multiple populations with some minor tweaks. They can be used cross-sectionally or longitudinally and are designed for a newly selected sample (e.g., include information on basic demographics). The survey asks questions about possible exposure to the virus, experiences with testing and treatment, and some questions about how life has changed as a result of COVID-19 and the preventive measures that have been put in place.
