The University of São Paulo (USP) Twin Panel (Painel USP de Gêmeos) was formally founded in 2017 at the Institute of Psychology of the USP by a faculty team under the leadership of Professor Emma Otta. It brings together twins interested in participating in research on basic psychological processes and behavior, and who are also interested in accessing services provided by the university. The main areas of research include subjective well-being and personality, the twin relationship as an attachment bond, cooperation and competition, and the development and cross-cultural adaptation of psychological questionnaires. In spite of being a new registry, in only two years of formal existence, it now comprises a database of 4826 participants. In this research project, our focus will be on the relationship of twin and non-twin siblings and the challenges faced during theCovid-19 pandemic. We have pre-pandemic results that we can compare with the results that will be collected at the time of Covid-19. (AU)
