#BoPo, #Ideal, or #Mixed? Exploring Adolescents’ Daily Exposure to Appearance Content on Social Media and Its Relations with Body Image Components

When using social media, adolescents encounter various types of appearance-related content. Yet, no research has explored how daily exposure to such types of content, including idealized content, body positivity (BoPo) content, and a mixture of both, links to adolescents’ body image states. With the present 14-day daily diary study among French adolescents ( N = 108, 1,434 daily assessments, M age = 15.99, 64.8% girls), we examined how exposure to idealized appearance content and BoPo content predicts adolescents’ state body satisfaction and surveillance on the same day and the next day. More so, we explored how the relationships may vary depending on a co-occurrence of exposure to both content types (i.e., mixed exposure). At a between-person level, exposure to idealized appearance and BoPo content was linked to higher body surveillance. At the within-level, BoPo content was associated with higher body satisfaction, meaning that on days that adolescents saw more BoPo content than usual (compared to their own means), they were also more satisfied with their bodies. However, these relations did not last until the following day. No other within-person level relations emerged. Also, when exploring the impact of the interaction between exposure to BoPo and idealized content, non-significant results emerged. The findings highlight the complexity of adolescents’ interactions with social media and emphasize the importance of future research adopting an ecological approach. This should involve considering both intra-individual and inter-individual factors, as well as the diverse types of social media exposure.
