摘　　要：目的探讨短视频使用对身体意象失调的影响,以及上行社会比较和外貌焦虑在两者之间的中介效应。方法选取贵州省某医科类高校的大学生作为被试,采用短视频使用量表、上行社会比较量表、外貌焦虑量表中文版和简版负面身体自我量表测量被试的短视频使用、外貌焦虑、上行社会比较及身体意象失调水平,获得有效问卷943份。对相关数据进行统计学分析。结果相关分析结果显示,短视频使用、上行社会比较、外貌焦虑和身体意象失调,各变量两两间均呈显著正相关(r=0.20~0.70,均P<0.01)。中介效应检验结果表明:短视频使用显著正向预测身体意象失调;在短视频使用与身体意象失调之间,上行社会比较和外貌焦虑具有独立的中介作用,且两者还通过“短视频使用→上行社会比较→外貌焦虑→身体意象失调”路径发挥链式中介效应。结论短视频使用可以直接预测大学生的身体意象失调。上行社会比较和外貌焦虑不仅各自独立地在短视频使用与身体意象失调之间起中介作用,还形成链式中介效应共同影响短视频使用与身体意象失调的关系。Objective To explore the impact of short-form video use on body image disorder,and investigate the mediating effect of upward social comparison and appearance anxiety between the two.Methods Students from a medical college in Guizhou Province were selected as participants.The survey was conducted by using the short-form video use scale,ascending social comparison scale,appearance anxiety scale,and simple negative physical self scale to measure the participants’levels of short-form video use,appearance anxiety,upward social comparison,and body image disorder.A total of 943 valid questionnaires were obtained.The relevant data were statistically analyzed.Results Correlation analysis showed that short-form video use,upward social comparison,appearance anxiety,and body image disorder were significantly positively correlated with each other(r=0.20-0.70,all P<0.01).The results of the mediation effect test indicated that the short-form video use significantly positively predicted body image disorder.Between the short-form video use and body image disorder,upward social comparison and appearance anxiety had independent mediating effects,and both also exerted a chain-mediated effect through the path of“short-form video use→upward social comparison→appearance anxiety→body image disorder”.Conclusion Short-form video use can directly predict the body image disorder of university students.Upward social comparison and appearance anxiety not only independently mediate the relationship between short-form video use and body image disorder,but also form a chain-mediated effect that jointly affects the relationship between short-form video use and body image disorder.
