Longitudinal event‑sampling dataset of football fans across five countries during the 2024 European championship

This dataset was collected during the UEFA EURO football championship in 2024. It provides match-contingent experience sampling data, including (a) individual-level variables such as life satisfaction, (b) interpersonal variables such as prosocial behaviors, and (c) broader societal variables such as political trust. The data points are nested in a sample of N = 1,012 individuals from five countries (England, Germany, Italy, the Netherlands, Poland). Using an event-sampling method with four to eight measurement waves (depending on how far the national team progressed in the tournament), we captured time-sensitive fluctuations in a total of m = 30 variables in response to the national team’s objective (i.e., win, draw, loss) and perceived success. In addition, the dataset contains moderating variables including Big-5 personality traits, conspiracy and free-will beliefs, or alcohol consumption and betting behaviors, and detailed match-specific data (e.g., shots on target, yellow cards, attendance). Following our preregistered gatekeeping approach, the data will be accessible for other scholars upon request. Our data descriptor portrays the methodological approach, data collection procedures, and available variables, and outlines how the data may be used for future research.
