Perceived event impacts of the Tokyo 2020 Olympic Games on residents’ eudaimonic well-being: a longitudinal study of within-person changes and relationships

The present study investigated 1) the changes in positive and negative event impacts and residents’ eudaimonic well-being before and after Tokyo 2020 and 2) how the social impacts are related to eudaimonic well-being. Three-wave panel data were collected from 1692 Japanese residents before and after the event. We performed linear mixed modeling (LMM) and a random-intercept cross-lagged panel model (RI-CLPM) to investigate the within-person fluctuations in the event impacts and eudaimonic well-being and the within-person relationships. The LMMs showed that only negative event impacts significantly changed after the event. The RI-CLPM revealed that positive event impacts before the event were significantly related to eudaimonic well-being right after the event, and eudaimonic well-being right after the event was significantly associated with positive event impacts two months after the event. The findings indicate that the influence of positive event impacts on residents’ eudaimonic well-being might be only temporal, but also eudaimonic well-being right after the event may have a significant role in positive evaluations of the event two months later. The results illustrated that the government and sport organizations need to pay more attention to contemplate the strategies to increase the eudaimonic well-being of residents through the power of sport to make “sport as an enabler of sustainable development”.
