Declines in Religiousness Dimensions across Adolescence as Predictors of Religious Deidentification in Young Adulthood.

The present study examined whether declines in religiousness across adolescence precede religious deidentification in young adulthood. Data came from the National Study of Youth and Religion. Participants were religiously affiliated for the first three waves of the longitudinal study (N = 1144). Latent growth curve models found significant declines across adolescence in church attendance, prayer, scripture study, religious importance, and spirituality, whereas doubt was stable across time. Then, logistic regression models specified the latent intercepts and slopes as predictors of later (Wave 4) deidentification. Significant negative links were found for the intercepts and slopes on church attendance, prayer, scripture study, religious importance, and spirituality. For doubt, a significant, positive link was found for the intercept.
