Longitudinal relationships among parental-adolescent attachment, peer attachment, self-concept clarity, and hope in adolescents.

Despite growing concerns regarding the development of hope among adolescents, the longitudinal relationship between parental-adolescent attachment, peer attachment, self-concept clarity, and hope remains far from being fully understood. This three-wave longitudinal study (6 months apart) across 1 year examined the relationship between attachment with parents and peers, self-concept clarity, and hope in 1,312 adolescents (age range 12-18, Mage = 14.29, SD = 1.38; 50.2% males) by using cross-lagged panel models. The results revealed a bidirectional relationship between hope and parental attachment across all three waves. In addition, hope was found to be positively associated with subsequent peer attachment across the three waves, while peer attachment at T1 was positively linked to hope at T2. Furthermore, self-concept clarity emerged as a longitudinal mediator in the relationship between both parental and peer attachment and hope. These findings underscore the potential implications for intervention programs focused on enhancing attachment and self-concept clarity to foster increased hope among adolescents.
