A review of social science literature reveals that, although most Americans claim to pray, little interest has been shown by researchers in the relationship between types ofprayer and quality of life. Survey data that focus on subjective perceptions of quality of life and items measuring the frequency of prayer and forms of religiosity are used to investigate the influence of types of prayer on five quality of life indices. Four distinct types ofprayer were revealed through a factor analysis of$fteen prayer activity items, each of which relate differently to the five quality of life measures. Prayer, like its parent concept of religiosity, is clearly multidimensional and contributes to profiling quality of life.
