인스타그램 외모 인플루언서에 대한 태도와 여자 청소년의 섭식장애 위험외모 기준 내면화와 신체 불만족의 직렬 매개효과

초록

This study examines how attitudes toward appearance-focused influencers affect the risk of eating disorders, with a particular focus on the mediating roles of thin-ideal internalization and body dissatisfaction. An online survey was conducted among Korean adolescent girls (N = 300), and a serial mediation model was tested using PROCESS Macro Model 87. The findings demonstrated a significant pathway in which favorable attitudes toward appearance-focused influencers on Instagram increased the risk of eating disorders by sequentially enhancing thin-ideal internalization and body dissatisfaction. However, the hypothesized moderated mediation effect of self-esteem was not supported. This study proposes the practical potential of a positive psychology-based functionality appreciation writing intervention, which focuses on body functionality, to attenuate appearance -focused body perceptions and to enhance positive body image. Overall, this study contributes both theoretically and practically by identifying the psychological mechanism underlying eating disorder risk among Korean adolescent girls and suggesting a functionality-focused intervention as a promising pathway for prevention.
