"Teens in this sample reported most frequent appearance comparison on TikTok and IG"

"US teens in this sample who saw a greater % of appearance-related FIT subtopics reported more appearance comparison (AC)." "Prior research identified a list of FIT subtopics, that when viewed in greater proportions, were associated with worse survey measures of appearance comparison. We manually reviewed content and narrowed the list in H2 '23. Topics include 'Lip Makeup (product)' and 'Fashion Photography.'" "Viewing a greater proportion of these FIT subtopics was associated with more frequent and more negative appearance comparisons on IG, even after controlling for teens' general body satisfaction, age, and gender identity." These findings extend prior AC work by:... Indicating that there is an independent relationship between teens' FIT topic exposure on IG and teen AC that is not likely explainable by teens' other relevant characteristics. This suggests that changing FIT topic exposure may be a way to reduce AC."
