Individual-Level Trajectories of Religiosity during Adolescence and Their Implications for Purpose.

Cohort-comparison studies suggest that adolescent religiosity has been declining over recent decades; however, work is needed on individual differences in patterns of change in religiosity throughout adolescence. The current study seeks to evaluate religiosity trends for adolescents as they transition from 6^th to 12^th grade, using seven annual waves of data, and whether these patterns of change were associated with later sense of purpose. Participants (n = 824; 50.7% female; 85.1% Caucasian) completed annual measures of religiosity from 6^th to 12^th grade, and a measure of sense of purpose at age 21 as part of the Oregon Youth Substance Use Project. Findings from latent growth models suggest both a mean-level decline in religiosity as well as individual differences in patterns of change across time. Furthermore, the intercept and change in religiosity throughout adolescence positively predicted sense of purpose at age 21. Results are discussed with respect to how individual differences occur in religiosity, and what that means for purpose development throughout adolescence.
