The Structural Model of the Effects of Insecure Attachment and Neuroticism on Internet Addiction among Iranian Adolescents: The Mediating Role of Alexithymia
摘要
Grounded in attachment theory, the Five-Factor Model, and emotion regulation theory, this study examined the structural relationships between insecure attachment styles (ambivalent and avoidant), neuroticism, alexithymia, and internet addiction among adolescents. A cross-sectional design was employed using stratified random sampling from high schools in Qom, Iran. A total of 420 adolescents aged 13–17 completed self-report measures, including the Internet Addiction Test (IAT), the Revised Adult Attachment Scale (RAAS), the Revised NEO Personality Inventory (NEO-PI-R), and the Toronto Alexithymia Scale (TAS-20). Structural equation modeling revealed significant direct effects of ambivalent attachment (β = 0.61), avoidant attachment (β = 0.66), and neuroticism (β = 0.55) on internet addiction, collectively explaining 81% of its variance. The mediating role of alexithymia was also supported (indirect βs = 0.42–0.62, p < 0.013 to p < 0.001). These findings underscore the importance of emotional regulation difficulties and psychological vulnerabilities in adolescent internet addiction and highlight the need for culturally sensitive interventions, including attachment-based therapies and emotional awareness programs.
