Abstract

PURPOSE

The link between maladaptive perfectionism and eating disorder (ED) pathology is well-established, yet less is known about factors that contribute to this relationship. The current study examined the mediating effect of aggression on the relationship between maladaptive perfectionism and ED pathology in a mixed-gender sample.

METHODS

Three-hundred and thirty-six participants (47.3% women) with a mean age of 35.75 (SD = 10.00) were recruited online through Amazon Mechanical Turk. Self-reported data were collected on ED pathology (Eating Disorder Examination-Questionnaire), perfectionism (Frost Multidimensional Perfectionism Scale), aggression (Buss-Perry Aggression Questionnaire), and demographic information.

RESULTS

Mediation analyses were performed separately for men and women using the SPSS PROCESS macro (Hayes in Introduction to mediation, moderation, and conditional process analysis: a regression-based approach, Guilford Press, New York, 2018). To test gender differences for specific model parameters, multiple-group structural equation modeling was used. Findings indicate that aggression partially mediated the relationship between maladaptive perfectionism and ED pathology in both men and women. There were no significant gender differences in the strength of the indirect effect or direct effect of perfectionism on ED pathology.

CONCLUSIONS

Findings from this study suggest that aggression may partially account for the relationship between maladaptive perfectionism and ED pathology. Additional research is needed to determine the temporal sequence of maladaptive perfectionism and aggression as it relates to ED pathology. Nonetheless, given their interrelationships, treatment research may benefit from examining interventions targeting aggression as a potential avenue for reducing ED symptoms.

摘要

目的

适应不良完美主义与饮食障碍（ED）病理之间的联系已得到充分证实，但对于导致这种关系的因素知之甚少。本研究在混合性别样本中检验了攻击性在适应不良完美主义与 ED 病理之间关系中的中介作用。

方法

通过 Amazon Mechanical Turk 在线招募了 336 名参与者（47.3%为女性），平均年龄为 35.75（SD=10.00）。使用 Eating Disorder Examination-Questionnaire（饮食障碍检查问卷）、Frost Multidimensional Perfectionism Scale（Frost 多维完美主义量表）、Buss-Perry Aggression Questionnaire（Buss-Perry 攻击性问卷）和人口统计学信息收集 ED 病理、完美主义、攻击性和人口统计学信息。

结果

使用 SPSS PROCESS 宏（Hayes 在《中介、调节和条件过程分析导论：基于回归的方法》，Guilford Press，纽约，2018 年）分别对男性和女性进行中介分析。为了测试特定模型参数的性别差异，使用多组结构方程建模。研究结果表明，攻击性在男性和女性中部分中介了适应不良完美主义与 ED 病理之间的关系。完美主义对 ED 病理的间接效应和直接效应的强度在性别上没有显著差异。
