Evolution of the concerns, perceptions and attitudes of the Spanish population during the COVID-19 pandemic

Both individual and population behavior are determining factors in controlling the spread of the COVID-19 pandemic. However, the restrictions have impacted the mental and physical well-being of citizens, the social cohesion, the economic stability, as well as the community resilience. In this complex scenario, understanding the feelings and attitudes of the population helps us to identify their needs and adopt response measures to control the pandemic in a more consensual and effective way. The COSMO-Spain study explores the concerns, perceptions, and attitudes of the population about the pandemic to find out the acceptance and adherence to behavioral prevention measures, as well as to analyze the citizens' risk perception, well-being and trust in information sources and institutions. The COSMO-Spain study has been carried out every two months since July 2020, through an online questionnaire to representative cross-sectional samples of the Spanish population, composed by 1000 people each. The results up to December 2021 show that the attitudes of the population are dynamic and evolve over time, influenced not only by individual factors, but also by contextual ones. Due to the changing nature of this pandemic, education and awareness campaigns need to be dynamic and continually updated based on real data.
