This research examined the longitudinal links between perceptions of family rituals, family cohesion, and adolescents' well-being in 713 adolescent-parent/caregiver dyads in New Zealand. Parents (86% mothers) assessed family ritual meaning and family cohesion, and adolescents (10 to 16 years old at Time 1) reported on family cohesion and well-being at two times of measurement with a 1-year interval. Structural equation modeling (SEM) was used to assess stability coefficients, cross-lagged effects, and to test a multistep mediation model. Results showed longitudinal bidirectional effects between perceptions of family ritual meaning and family cohesion (for parents), and between perceptions of family cohesion from parents/caregivers and adolescents. In addition, family ritual meaning was found to be linked to adolescents' well-being indirectly via parents' and adolescents' family cohesion. Results support and expand previous research on the direct and indirect effects of family rituals in family and individual positive outcomes.
