摘　　要：目的考察大学生亚临床躯体变形障碍的发生率并探讨自尊在体像困扰与大五人格之间的中介作用。方法采用问卷调查法对南京市四所高校的1166名大学生进行测查。结果大学生亚临床躯体变形障碍的发生率为6.2%。相关分析显示,体像困扰[(35.2±18.4)分]与自尊[(29.0±4.3)分]呈显著负相关(r=-0.41,P<0.01),与大五人格中的神经质[(32.9±8.1)分]呈显著正相关(r=0.52,P<0.01),与外向性[(39.6±6.8)分]、开放性[(39.8±6.4)分]、宜人性[(41.7±4.7)分]、严谨性[(40.1±6.4)分]维度呈显著负相关(r=-0.18,-0.14,-0.14,-0.25;均P<0.01)。自尊在大五人格与体像困扰之间的中介效应量为19.7%。结论大学生亚临床躯体变形障碍的发生率较高;大五人格既可直接预测体像困扰,也可通过自尊的中介作用间接预测体像困扰的程度。Objective To explore the prevalence of subthreshold body dysmorphic disorder in an undergraduates sample and investigate the mediating role of self-esteem on big five personality and body image disturbance.Methods A sample of 1 166 undergraduates coming from four different colleges were recruited to complete questionnaire survey.Results The prevalence of subthreshold body dysmorphic disorder in undergraduates was 6.2%.Body image disturbance(35.2±18.4)was negatively correlated with self-esteem((29.0±4.3),r=-0.41,P<0.01),positively correlated with neuroticism((32.9±8.1),r=0.52,P<0.01)while negatively correlated with extraversion(39.6±6.8),openness(39.8±6.4),agreeableness(41.7±4.7)and conscientiousness((40.1±6.4),r=-0.18,-0.14,-0.14,-0.25;all P<0.01).The mediating role of self-esteem was 19.7%.Conclusion The prevalence of subthreshold body dysmorphic disorder in undergraduates is rather high.Big five personality can directly predict body image disturbance and indirectly predict body image disturbance through the mediating role of self-esteem.
