Abstract

This study aimed to explore the effects of SNS appearance-related photo activities on disordered eating behaviors among women in their 20s, mediated by self-objectification and interoceptive awareness. Data were collected via self-report questionnaires from 300 female participants in their 20s (M = 25.29 years, SD = 3.06) recruited through the online survey platform. Structural equation modeling was conducted using SPSS 25.0 and Mplus 8.3. The results were as follows. SNS appearance-related photo activities sequentially influenced disordered eating behaviors through self-objectification and interoceptive awareness subscales, specifically attention regulation and trust, which are represented as bodily sensation awareness and management. Notably, enhanced bodily sensation awareness and management reduced disordered eating behaviors, indicating that specific subscale of interoceptive awareness may act as risk factors for psychopathology. This study provides valuable insights into the pathways through which SNS appearance-related photo activities influence disordered eating behaviors, offering foundational data for developing prevention and intervention strategies for eating disorders.
