We examined the associations of different types of prayer with subjective well-being- with a religious support as a potential moderator-in a sample of Korean adults. In a cross-sectional study, 468 participants completed measures of five prayer types (adoration, confession, thanksgiving, supplication, and reception prayer), subjective well-being, and religious support. After controlling for background variables, the thanksgiving prayers had positive associations and supplication prayers had negative associations with subjective well-being. In examining the potential moderating role of religious support, the current findings showed that religious support strengthened the relationship between reception prayer and subjective well-being, especially among individuals who perceived moderate and high levels of religious support. These findings indicate differential associations between prayer type and well-being in Korean adults.
