Delivering community-based benefits is oftentimes cited to justify the high costs associated with hosting large-scale events. The current research is embedded in positive psychology to examine how an event impacts host community members’ PERMA domains, reflected through positive emotions, engagement, relationships, meaning, and accomplishment. Adopting a longitudinal approach, the authors interviewed 15 host community members before and after a large-scale sport event to determine if and how the event impacted their well-being. The findings uncovered evidence that the event activated positive emotions, relationships, and meaning across both phases, and evidence of accomplishment within the postevent phase. The findings contribute to the knowledge by examining the links between large-scale sport events and well-being throughout the event lifecycle. This research forwards implications for event bidding committees, event organizers, and host community officials to maximize community well-being through hosting large-scale events and to help justify associated expenses from a social–psychological perspective.
