During COVID-19, there has been a need to gather reliable empirical data on the consequences for behavior and psychological well-being in society as well as to inform and educate individuals comprehensively. The WIBCE online survey tool offers the possibility to (1) inform, reflect, and empower participants to be more self-aware regarding psychological, medical, and behavioral factors, and (2) aggregate anonymously shared data to statistically analyze the impact of COVID-19. Thereby, it allows a one-time but also longitudinal (i.e., on a regular basis) participation. Analyzing the collected survey data from April to August 2020, we found two subgroups that differ fundamentally in terms of mental health and psychological well-being. These differences were present not only at one time point but could also be traced longitudinally. The knowledge of the cluster affiliation allows to provide participants specific, personalized feedback as well as individual recommendations.
