摘要目的:探讨外貌功能性内化在大学生社会比较倾向与体像烦恼之间的中介作用。方法:2023年6—9月，采用社会比较倾向量表、大学生外貌功能性内化问卷、青少年学生体像烦恼问卷对308位在校大学生开展横断面调查。使用SPSS 22.0进行共同方法偏差检验、描述统计、相关分析，利用Mplus 8.0进行结构方程建构，采用Bootstrap方法进行中介效应分析。结果:体像烦恼[(43.86±8.78)分]与社会比较倾向[(35.20±6.04)分]、外貌功能性内化[(38.35±9.68)分]均呈正相关( r＝0.35，0.33，均 P<0.01)，社会比较倾向与外貌功能性内化也呈正相关( r＝0.51， P<0.01)。大学生社会比较倾向对体像烦恼的影响中外貌功能性内化起到部分中介作用，中介效应的效应值为0.137，占总效应的35.13%(0.137/0.390)。 结论:外貌功能性内化在社会比较倾向和体像烦恼之间起部分中介作用，社会比较倾向不仅能够直接预测体像烦恼，而且能够通过外貌功能性内化对体像烦恼产生间接影响。

abstractsObjective:To explore the mediating effect of appearance functional internalization between social comparison tendency and body image distress of college students.Methods:From June to September 2023, a cross-sectional survey was conducted among 308 college students with the social comparison tendency scale, the functional internalization questionnaire of college students' appearance and the body image anxiety scale for adolescent students.SPSS 22.0 software was used for common method bias test, descriptive statistics and correlation analysis, Mplus 8.0 was used for structural equation construction, and Bootstrap method was used for intermediary effect analysis.Results:Body image distress (43.86±8.78) was positively correlated with social comparison tendency (35.20±6.04) and appearance functional internalization (38.35±9.68) ( r=0.35, 0.33, both P<0.01).There was also a positive correlation between social comparison tendency and appearance functional internalization ( r=0.51, P<0.01). The effect of social comparison tendency on body image distress was mediated by appearance functional internalization, and the mediating effect value was 0.137, accounted for 35.13%(0.137/0.390) of the total effect. Conclusion:The appearance functional internalization mediates the relationship between social comparison tendency and body image distress.Social comparison tendency can not only directly predict body image distress, but also can predict body image distress, indirectly through appearance functional internalization.
