RT Journal Article T1 The effect of secure attachment on family relationships and peer bullying in adolescents: the mediating role of positive childhood experiences A1 Çiçek, İlhan A1 Korkmaz, Zafer A1 Ünsal, Firat A1 Alanazi, Zainab Shalal A1 Gómez Salgado, Juan A1 Yildirim, Murat AB Aims: This study examines whether positive childhood experiences (PCEs) mediate the relationship between secure attachment and family conflict, peer bullying, and family cohesion in adolescents.Method: The sample includes 574 high school students [301 female (52.4%), 273 male], aged 14 to 18 years (M = 16.28, SD = 1.45). Participants completed the Brief Family Relationships Scale, the Attachment Styles Scale, the Peer Bullying Scale, and the Positive Childhood Experiences Scale. Results: Findings revealed that secure attachment was positively associated with PCEs, which in turn were linked to greater family cohesion and lower levels of family conflict and peer bullying. Mediation analyses confirmed that PCEs significantly mediated the relationship between secure attachment and family conflict, peer bullying, and family cohesion.Conclusion: These findings suggest PCEs as a key variable linking secure attachment to adolescents’ social and family adjustment. They emphasize the critical role of nurturing supportive developmental environments across diverse contexts.
