This study examines the causal effect of different voluntary roles in sport on individuals’
subjective well-being. Theoretically, volunteering can affect well-being through various
mechanisms, including enjoyment, new contacts, skill development, exercising altruism, and
relational goods. The empirical analysis uses data from 28 European countries (n=52,957).
Subjective well-being is measured with self-reported life satisfaction. The number of
administrative roles (e.g. board or committee member, administrative tasks), sport-related
roles (e.g. coach, instructor, referee), and operational roles (e.g. organise a sport event,
provide transport) capture volunteering. The results of linear regression models support the
positive relationship between volunteering and subjective well-being as evident in existing
research. However, instrumental variable estimates reveal that only the number of operational
roles has a significant positive effect on well-being, while the effects of administrative and
sport-related roles are jointly significantly negative. The findings of this study have
implications for sport organisations and policy makers.
