“…We examined the three mediational relations of screen time for social media, overall smartphone use, and specific smartphone activities to body esteem in female adolescents by focusing on three sequential mediators of cognitive internalization of thin ideals, engagement in social comparison, and social appearance anxiety. In all analyses, we controlled for key covariates of age, income, body mass index (BMI), and internal locus of control over one’s body, all of which have been suggested as factors that influence body esteem [ 29 , 58 , 60 , 61 ]. We used the PROCESS macro [ 62 ] in SPSS (SPSS Inc., Chicago, IL, USA), which estimates the 95% confidence interval (CI) for indirect effects based on 5000 bootstrap samples.…”
