从强迫运动到进食障碍症状:依恋的中介效应

From Compulsive Exercise to Eating Disorder Symptoms:The Mediating Effect of Attachment

目的:考察在校大学生依恋关系在强迫运动与进食障碍症状之间的中介效应。方法:研究一和研究二采用问卷调查法分别对466名男大学生和334名女大学生的依恋焦虑、依恋回避水平、强迫运动和进食障碍临床症状进行考察,通过分层回归检验依恋焦虑和依恋回避在强迫运动与进食障碍症状间的中介效应,并用Bootstrap法对中介效应进行验证。结果:在男女大学生中强迫运动可显著预测进食障碍症状;在男生当中,依恋的两个维度依恋焦虑和依恋回避在强迫运动与进食障碍间的部分中介作用显著;在女生当中,仅依恋焦虑起到部分中介作用。结论:强迫运动是进食障碍症状的重要风险因子,可通过依恋关系的中介作用影响进食障碍症状,依恋关系对强迫运动与进食障碍症状之间关系的中介效应具有性别差异。

Objective:The study examined the role of attachment in mediating the relationship between compulsive exercise and eating disorder symptoms among college students.Methods:Participants were 466 male(study 1)and 334 female(study 2)college students.Self-report questionnaires adopted to assess attachment,compulsive exercise and eating disorder symptoms.Results:Compulsive exercise predicted eating disorder symptoms significantly in both samples.Among men,both dimensions of adult attachment,namely attachment anxiety and attachment avoidance,partially mediated the relationship between compulsive exercise and eating disorder symptoms,while only attachment anxiety mediated the pathological pathway from compulsive exercise to eating disorder symptoms in women.Conclusions:Compulsive exercise was an important risk factor in developing eating disorder symptoms among college students,anxiety and avoidance dimensions of attachment could explain the association between compulsive exercise and eating disorder symptoms.Further,the mediating role of attachment differed between men and women.
