Dysfunctional appearance beliefs have been identified as important risk factors in the development of body dissatisfaction and disordered eating behaviors among early adolescents. The current two‐wave study among 10–14‐year‐olds (N = 1,597, Mage = 11.25, SD = 1.05) aimed to delineate factors that contribute to the endorsement of such beliefs. Results showed that tweens discussed appearance‐related topics with their friends more often when they frequently watched tween television programs (all time 1). Both media exposure and peer conversations (time 1) were related to attributing benefits to attractiveness (time 1), which, in turn, predicted the internalization of appearance ideals (time 1). The internalization of appearance ideals positively predicted the endorsement of dysfunctional appearance beliefs 6 months later.
