Is the relationship between passive social network usage and body image concerns via physical appearance comparison a vicious circle? Evidence from Taiwan and Vietnam
摘要
Previous research has shown that passive social networking usage (PSNU) can contribute to adolescents’ body image concerns (BIC). A reciprocal relationship is believed to exist, where increased PSNU heightens BIC, which, in turn, drives further PSNU. While physical appearance comparison (PAC) is believed to play a key role in this dynamic, it remains underexplored. This study examined the reciprocal relationship between PSNU and BIC in adolescents, with a focus on the mediating role of PAC, and compared patterns between Vietnamese and Taiwanese students. A two-wave longitudinal survey was conducted with 957 adolescents (456 in Taiwan and 501 in Vietnam). Guided by Social Comparison Theory and Cognitive Dissonance Theory, the findings revealed a reciprocal association between PSNU and BIC over time, with PAC serving as a significant mediator in both cultural contexts. However, the specific mediating patterns varied between countries. These results highlight the importance of psychological support programs that help adolescents navigate body image concerns and social media use. Study limitations are also discussed.
