The purpose of this study was to describe and explore three phenomenon of the L.D.S. Family Home Evening Program: (1) the nature of religious commitment in an L.D.S. sample, (2) the degree of participation, (3) the relation of certain religious and secular variables.The data for the study were made available to the researcher by A. L. Mauss, as part of a larger study designed to measure the impact of Urbanism upon Mormonism. The instrument, modeled after the Glock and Stark studies, was adapted to a random sample of 958 members of the L.D.S. Church in Utah.The nature of religious commitment was found to be multi-dimensional. Normative participation in the program was low when compared with similar Church programs. None of the variables showed a high correlation with participation.It was concluded that the Church has not yet succeeded in designing the Program to meet the needs of most Church members, and that some weightier factors must account for participation and/or non-participation in the Program than those tested.
