Abstract

BACKGROUND

Previous studies have shown that sexual objectification experience is closely related to eating disorders in adolescent female students, but the mechanisms and conditions under which online sexual objectification experience influences disordered eating in female college students need to be further explored. Therefore, this study aimed to explore the mediating and moderating variables of the relationship between online sexual objectification experience and disordered eating, and to provide suggestions for the prevention of disordered eating among female college students.

METHODS

A total of 651 female college students were tested with Online Sexual Objectification Experience Scale, Body Surveillance Scale, Physical Exercise Scale and Disordered Eating Scale. The mediating role of body surveillance and the moderating role of physical exercise were examined using the latent structural equation approach and Model 15 in version 3.5 of the Process macro program, respectively.

RESULTS

Online sexual objectification experience, body surveillance, and female college students' restrictive eating, emotional eating, and exogenous eating were significantly and positively correlated with each other; body surveillance mediated the relationship between online sexual objectification experience and female college students' restrictive eating, emotional eating, and exogenous eating, respectively; physical exercise significantly and negatively moderated the relationship between online sexual objectification experience and female college students' restrictive eating, and the higher the level of physical exercise, the lower the predictive effect of online sexual objectification experience on female college students' restrictive eating.

CONCLUSIONS

Body surveillance mediated the relationship between online sexual objectification experience and disordered eating among female college students, and physical exercise only moderated the relationship between online sexual objectification experience and restrictive eating among female college students.

摘要

背景

以往研究表明，性客体化经历与青春期女学生的饮食失调密切相关，但网络性客体化经历影响女大学生饮食失调的机制和条件尚需进一步探索。因此，本研究旨在探讨网络性客体化经历与饮食失调之间关系的中介和调节变量，并为预防女大学生饮食失调提供建议。

方法

对651名女大学生进行了网络性客体化经历量表、身体监测量表、体育锻炼量表和饮食失调量表测试。分别采用潜在结构方程方法和Process宏程序3.5版本中的模型15检验身体监测的中介作用和体育锻炼的调节作用。

结果

网络性客体化经历、身体监测与女大学生的限制型饮食、情绪化饮食和外部驱动型饮食之间均呈显著正相关；身体监测分别中介了网络性客体化经历与女大学生限制型饮食、情绪化饮食和外部驱动型饮食之间的关系；体育锻炼显著负向调节网络性客体化经历与女大学生限制型饮食之间的关系，体育锻炼水平越高，网络性客体化经历对女大学生限制型饮食的预测作用越低。
