Individuals with a history of sexual victimization are at increased odds of developing an eating disorder in their lifetime. Emotion dysregulation has been identified as an outcome of sexual victimization and a vulnerability factor in the emergence and maintenance of disordered eating. However, research in this area has been limited by its narrow focus on dysregulation stemming from negative emotions. The aim of the current study was to explore the potential moderating roles of negative and positive emotion dysregulation in the relations between sexual victimization and disordered eating.
Study participants included 473 community individuals who endorsed a history of sexual assault (M = 34.66; 44.8% male; 78.4% White). Participants completed measures assessing sexual victimization, negative and positive emotion dysregulation, and disordered eating. Data was collected from January to April of 2020 via Amazon's Mechanical Turk.
Results indicated significant positive relations among sexual victimization, negative and positive emotion dysregulation, and disordered eating. Sexual victimization was found to be more strongly associated with disordered eating at high (vs. low) levels of negative and positive emotion dysregulation.
This study provides evidence for the strengthening roles of both high negative and positive emotion dysregulation in the relation between sexual victimization and disordered eating, suggesting the potential utility of targeting both negative and positive emotion dysregulation in disordered eating interventions among individuals with a history of sexual victimization.
有性受害史的个体一生中出现饮食障碍的可能性增加。情绪调节障碍已被确定为性受害的后果，也是出现和维持饮食障碍的脆弱因素。然而，该领域的研究受到其狭隘的关注的限制，即仅关注源于负面情绪的失调。本研究旨在探讨负性和正性情绪失调在性受害与饮食障碍关系中的潜在调节作用。
研究参与者包括 473 名有性侵犯史的社区个体（M=34.66；44.8%为男性；78.4%为白人）。参与者完成了评估性受害、负性和正性情绪失调以及饮食障碍的测量。数据于 2020 年 1 月至 4 月通过亚马逊的 Mechanical Turk 收集。
结果表明，性受害与负性和正性情绪失调以及饮食障碍之间存在显著的正相关。与低水平的负性和正性情绪失调相比，在高水平的负性和正性情绪失调时，性受害与饮食障碍的关系更为密切。
本研究为性受害与饮食障碍之间的关系中，负性和正性情绪失调的增强作用提供了证据，这表明在有性受害史的个体中，针对饮食障碍干预中的负性和正性情绪失调可能具有潜在的效用。
