Social Skills and Peer Relationships as Serial Mediators Between Mindfulness and Spiritual Well-Being in Adolescence

<b>Objectives</b>: This study aimed to investigate the mediating roles of social skills and peer relationships in the association between mindfulness and spiritual well-being (SWB) among adolescents. Drawing on the mindfulness-to-meaning theory, the research sought to clarify how mindfulness supports adolescents' spiritual well-being through social and relational mechanisms. <b>Method</b>: A correlational research design was employed with a sample of 761 adolescents attending high schools in Türkiye. Data were collected using the Mindful Attention Awareness Scale, Social Skills Scale, Peer Relations Scale, and the Three-Factor Spiritual Well-Being Scale. The hypothesized serial mediation model was tested using PROCESS Macro Model 6 with 5000 bootstrap samples. <b>Results</b>: Mindfulness was positively associated with SWB. Both social skills and peer relationships showed significant mediating effects. The serial indirect effect through social skills and peer relationships was also significant. <b>Conclusions</b>: Findings highlight mindfulness as a key psychosocial resource that enhances adolescents' spiritual well-being through improved social skills and supportive peer relationships. School-based mindfulness programs should integrate peer interaction and social skills components to promote adolescents' holistic development.
