摘要
目的:探讨体质量指数(Body Mass Index,BMI)、嘲笑、身体意象和自尊的关系。方法:采用方便抽样,从湖北省某2所高中选取学生390名,根据BMI得分将被试分为偏瘦组(BMI≤17分),正常组(17分22分)。使用青少年身体自我量表(Adolescent PhysicalSelf Scale,APS)、知觉到的嘲笑量表(The Perception of Teasing Scale,POTS)和自尊量表(The Self-Es-teem Scale,SES)考察体质量指数、嘲笑、身体意象与自尊的关系。结果:①BMI分组,偏瘦组女生多于男生,而偏胖组男生多于女生(χ2=8.48,P<0.05)。女生POTS得分高于男生,而APS得分低于男生。②偏胖组POTS得分和SES得分均高于正常组和偏瘦组;偏瘦组APS得分高于正常组和偏胖组。③APS得分与BMI、POTS得分呈负相关(r=-0.43,-0.31;均P<0.01),与SES得分正相关(r=0.45,P<0.05)。④回归分析发现,BMI、知觉到的嘲笑和身体意象可以直接预测自尊(β=-0.15,-0.11,0.36),解释总变异的24%。中介效应检验发现,BMI、知觉到的嘲笑可以直接影响自尊,也可以通过身体意象间接影响自尊。结论:体质量指数、知觉到的嘲笑和身体意象是影响自尊的重要因素,并且身体意象在体质量指数、知觉到的嘲笑与自尊的关系中起着部分中介的作用。
