In total, 804 social media users from T & uuml;rkiye (Mage = 30.45 +/- 8.12; 61.9% women) completed the Bergen Social Media Addiction Scale, Scale. A parallel mediation model indicated that social appearance anxiety predicted PSMU. Further, selfitis behaviors and adaptable self mediated the effects of social appearance anxiety on PSMU. Lastly, adaptable self-moderated the relationship between social appearance anxiety and selfitis behaviors. The study suggests that social appearance anxiety can be considered a risk factor, and the adaptable self and selfities behavior may mitigate the effect of social media appearance anxiety on problematic social media use. These findings can inform the development of interventions and preventive strategies to reduce the psychopathological effects of social media addiction.eninfo:eu-repo/semantics/openAccessSocial Appearance AnxietyProblematic Social Media UseSelfitis BehaviorAdaptable SelfArticle
