Prior research suggests the significance of religion for development and wellbeing in adolescence and beyond. Further, new developments and applications of statistical methods have led to ways of better accounting for the multidimensional nature of religiosity (e.g. latent class analysis), as well as the dynamic aspects of religiosity (e.g. latent growth curve models). Yet, rarely if ever are both features of religiosity incorporated and examined together. Therefore, we propose and conduct a latent class analysis using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to identify seven distinct pathways of religiosity that involve independently changing levels of religious affiliation, religious service attendance, personal importance of religion, and prayer from adolescence to adulthood. We also show how individuals’ religious pathways are related to gender, race, parents’ education, their own education, and family formation experiences in the transition to adulthood. Our findings inform the study of how multiple dimensions of religiosity take shape across adolescence and the transition to adulthood, and suggest a new way for measuring the dynamics of religiosity in studies of the impact of religion across the life course.
