OBJECTIVE
To examine mediators of the relationship between perfectionism and eating disorder (ED) psychopathology in a clinical sample.
METHOD
Participants were 201 women with a DSM-IV diagnosed ED consecutively referred to a specialist outpatient treatment clinic. Participants completed measures of perfectionism, ED psychopathology, shape and weight overvaluation, and conditional goal-setting (CGS).
RESULTS
Evaluation of a multivariate mediator model using Baron and Kenny's (1986) four-step mediation methodology showed that shape and weight overvaluation and CGS significantly and uniquely mediated the relation between self-oriented perfectionism (SOP) and restraint, eating concern, shape concern, and weight concern. The mediator model furthered the proportion of explained variance in outcomes beyond the direct effects model by 28-49%.
DISCUSSION
The findings support the conclusion that the relationship between SOP and ED psychopathology in women with a clinically diagnosed ED is mediated by shape and weight overvaluation and CGS.
目的
在临床样本中研究完美主义与饮食障碍（ED）心理病理学之间关系的中介因素。
方法
参与者为 201 名女性，她们被 DSM-IV 诊断为 ED，并连续被转介到专科门诊治疗诊所。参与者完成了完美主义、ED 心理病理学、体型和体重高估以及条件目标设定（CGS）的测量。
结果
使用 Baron 和 Kenny（1986）的四步中介方法评估多变量中介模型显示，体型和体重高估以及 CGS 显著且独特地中介了自我导向完美主义（SOP）与抑制、饮食关注、体型关注和体重关注之间的关系。该中介模型将结果的可解释方差比例进一步提高了 28-49%，超过了直接效应模型。
讨论
研究结果支持这样的结论，即患有临床诊断 ED 的女性中，SOP 与 ED 心理病理学之间的关系是由体型和体重高估以及 CGS 介导的。
