To fill this research gap, the aim of this study was to explore the influencingmechanisms of internalization of media appearance ideals on adolescents’ eating disorder tendencies in Chinese cultural context. The Sociocultural Attitudes Towards Appearance Questionnaire, Eating Attitude Test-26, Physical Self-Description Questionnaire, Body Image Depression Questionnaire and Multidimensional Scale of Perceived Social Support were employed in this study to investigate 1523 adolescents. The collected data were analyzed using SPSS 26.0 and AMOS 24.0. The results showed that: 1) internalization of media appearance ideals had a significant positive predictive effect on adolescents’ eating disorder tendencies; 2) internalization of media appearance ideals significantly influenced adolescents' eating disorder tendencies through the mediating role of body esteem and body image disturbance respectively, and also influencedeating disorder tendencies through the chain mediating of both; and 3) social support playeda moderating role between body image disturbance and eating disorder tendency.
