Show moreResearch has been limited in assessing the different impacts of social media platforms on body dissatisfaction, apart from Facebook. In addition, most studies have measured social media use by only assessing time. This study aimed to test experimental effects of social comparison on body dissatisfaction (BD) and desire to engage in eating behaviors. In addition, a mediation model was tested of the association between social media use and BD via social comparison. Participants viewed one of two live public Instagram profiles and were asked questions that facilitated individuals comparing their appearance to the Instagram profile. A total of 74 women completed questionnaires regarding social media use, body image, and eating disorder psychopathology. It was found that regardless of condition, desire to eat decreased after profile views, but there was no change in BD. The mediation model suggests that there was a significant indirect effect of increased BD and importance of Instagram through social comparison. Results suggest that, contrary to earlier work, overall social media use may not negatively impact BD as previously thought. Rather, it appears that trait level factors such as social comparison negatively influence BD while using social media. Show less
