Abstract

Extensive social media usage causes psychological dependence and impacts people’s self-evaluations. It is vital to seek possible buffers to social media addiction’s detrimental effect on self-esteem and body image. Poland has one of the highest scores on problematic social media usage. Past studies pointed to narcissism and self-compassion as possible mediators of such effects. The present study aimed to explore Polish individuals’ (N=527) social media usage habits. We hypothesised gender differences and social media addiction predictive effect on self-evaluations (self- esteem, body image), with narcissism and self-compassion as mediators of such relationships. The results revealed that only visual media (Facebook, Instagram, TikTok) had a negative effect on self-evaluations and that women reported more social media addiction and decreased self-esteem, self-compassion and body image. Social media addiction was negatively predicting body image for both genders and self-esteem for women but not for men, with self-compassion and narcissism mediating such relationships.
