Abstract

The literature on body image ramifications of girls' uses of appearance-focused social media (ASM) is limited, and even non-existing in terms of TikTok uses. With this brief report, we aimed to fill this gap in the literature by analyzing three waves of data on girls' ASM use and body image-related constructs (i.e., internalization of beauty ideals and body image self-discrepancy) using random-intercept cross-lagged panel models (RI-CLPMs). The total sample consisted of 229 girls (M age = 15.12, SD = 1.50). Controlling for age and body mass index (BMI), the RI-CLPMs revealed that neither TikTok nor Instagram were predictive of subsequent increases or decreases in internalization of beauty ideals and body image self-discrepancy. Lower scores on body image self-discrepancy at W2 (i.e., wanting to have a thinner body) did predict higher uses of Instagram at W3. No evidence for between-person effects was garnered. The results enrich our knowledge on long-term implications of girls' Instagram and TikTok use for their body image. They further underline the need for research that more specifically disentangles the role of different appearance-related activities on social media and their impact on girls' body image constructs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
