The COSMO study is designed as a serial cross-sectional online survey in which approximately 1,000 people have participated in weekly to fortnightly data collections since 3.3.2020. Respondents are invited and paid via the panel provider Respondi. Regularly, a representative distribution of respondents between 18-74 years of age by age × gender as well as federal state based on the census data from Germany is aimed at. Since the sample is limited to people with internet access, respondents who are 75 years or older are not included in the analyses.
