社交媒体使用对负面身体意象的影响——自我价值感权变和上行社会比较的链式中介作用
The Effect of Social Media Use on Negative Body Image—The Chain Mediating Role of Contingencies of Self-Worth and Upward Social Comparison
摘要: 目的：更深入地了解社交媒体使用对身体意象的影响，及自我价值感权变和上行社会比较在其中的作用。方法：使用社交媒体使用强度量表、自我价值感权变量领域量表、上行社会比较量表和身体意象量表对全国559名在校大学生进行测量。结果：(1) 外貌相关社交媒体使用与负面身体意象呈显著正相关。(2) 自我价值感在外貌、他人认可领域的权变和上行社会比较在外貌相关社交媒体使用和负面身体意象之间的中介作用显著。该中介包含五条路径：自我价值感在外貌领域权变、他人认可领域的权变和上行社会比较的单独中介作用，自我价值感在外貌、他人认可领域的权变分别与上行社会比较的链式中介作用。结论：社交媒体使用中参与外貌相关活动的时间越长，个体越容易将自我价值感建立在外貌和他人认可上，进而越容易进行上行社会比较，从而导致负面身体意象。而外貌相关社交媒体使用既可以直接影响身体意象，也可以通过自我价值感权变和上行社会比较这一链式中介间接对身体意象产生影响。
Abstract: Objective: To better understand the impact of social media use on body image and the role of contingencies of self-worth and upward social comparison. Methods: Social media use intensity scale, self-worth power variable domain scale, upward social comparison scale and body image scale were used to measure 559 college students in China. Results: (1) There was a significant positive correlation between appearance-related social media use and negative body image. (2) Contingent changes in appearance, others’ approval and upward social comparison significantly mediate appearance-related social media use and negative body image. The mediation consists of five pathways: the individual mediating role of self-worth in the field of appearance contingent, the contingent role of others’ approval and upward social comparison, and the chain mediating role of self-worth in the field of appearance contingent and the contingent role of others’ approval and upward social comparison respectively. Conclusion: The longer the time spent on appearance-related activities in social media use, the easier it is for individuals to base their sense of self-worth on appearance and others’ approval, and the easier it is for them to make upward social comparison, which leads to negative body image. However, appearance-related social media use can affect body image either directly or indirectly through the chain mediation of contingencies of self-worth and upward social comparison.
