Research project PANDEMIC

Pandemic COME-HERE survey

The COME-HERE panel survey (COVID-19, MEntal HEalth, REsilience and Self-regulation) has been conducted since April 2020. The data is collected by Qualtrics to produce representative samples of adults (aged 18 or over) in France, Germany, Italy, Spain and Sweden. Stratification ensured that the data in Wave 1 was representative in terms of gender, region and age within each country. In Luxembourg, the data is collected first with interviews carried out by TNS-ILRES starting in 2021, and on a convenience sample (SoSci) in 2020 and 2021.

Respondents in all countries are asked to complete an on-line questionnaire that takes approximately 20 minutes. The survey collects information at both the individual and household levels and is longitudinal.
