["Journal for the Scientific Study of Religion, EarlyView. ", "\nABSTRACT\nAlthough religious service attendance is touted for its reliable measurement and robust associations with well‐being, the overwhelming focus on attendance has allowed other aspects of religious participation to be significantly understudied. This study investigates whether short‐term religious retreats and mission trips contribute to young adults’ subjective well‐being beyond the well‐documented effects of attendance. Using longitudinal data from Waves 3 and 4 of the National Survey of Youth and Religion (NSYR) (N = 1243), we conduct cross‐lagged structural equation models to assess relationships between retreat or mission participation and four outcomes of well‐being: life meaning (eudaimonic), physical (global self‐rated health), mental health (depression), and hedonic (life satisfaction). Baseline models show modest positive associations, where retreat participation predicts greater life satisfaction and meaning in life, and mission trips predict higher self‐rated health and life satisfaction. However, once religious service attendance is included, almost all associations lose statistical significance. Although retreats and missions may provide temporary benefits, their effects on enduring well‐being largely reflect broader engagement in congregational life.\n"]
