Abstract

Purpose: We provide the first systematic review and meta-analysis of research examining multidimensional perfectionism-perfectionistic strivings and perfectionistic concerns-and orthorexia.

Methods: The systematic review and meta-analysis was pre-registered and conducted using a search of PsycINFO, MEDLINE, Education Abstracts, and Oxford Academic, and ScienceDirect up to April 2023. PRISMA guidelines were also followed. Meta-analysis using random-effects models was used to derive independent and unique effects of perfectionism, as well as total unique effects (TUE), and relative weights. Moderation of effects were examined for age, gender, domain, perfectionism and orthorexia instruments, and methodological quality.

Results: Eighteen studies, including 19 samples (n = 7064), met the eligibility criteria with 12 of these studies (with 13 samples; n = 4984) providing sufficient information for meta-analysis. Meta-analysis revealed that perfectionistic strivings (r+  = 0.27, 95% CI [0.21, 0.32]) and perfectionistic concerns (r+  = 0.25, 95% CI [0.18, 0.31]) had positive relationships with orthorexia. After controlling for the relationship between perfectionism dimensions, only perfectionistic strivings predicted orthorexia which also contributed marginally more to an overall positive total unique effect of perfectionism (TUE = 0.35; 95% CI [0.28, 0.42]). There was tentative evidence that orthorexia instrument moderated the perfectionistic concerns-orthorexia relationship.

Discussion: Research has generally found that both dimensions of perfectionism are positively related to orthorexia. More high-quality research is needed to examine explanatory mechanisms while also gathering further evidence on differences in findings due to how orthorexia is measured, as well as other possible moderating factors.

Level of evidence: Level 1, systematic review and meta-analysis.

多维完美主义与厌食症:系统回顾与荟萃分析。
目的:我们首次对研究多维完美主义--完美主义追求和完美主义关注--以及厌食症的研究进行了系统回顾和荟萃分析:该系统性综述和荟萃分析已进行了预先登记,并在 PsycINFO、MEDLINE、Education Abstracts、Oxford Academic 和 ScienceDirect 上进行了检索(截至 2023 年 4 月)。同时还遵循了 PRISMA 指南。使用随机效应模型进行元分析,得出完美主义的独立效应和独特效应,以及总独特效应(TUE)和相对权重。对年龄、性别、领域、完美主义和正视心理工具以及方法学质量的影响调节进行了研究:18项研究(包括19个样本,n=7064)符合资格标准,其中12项研究(包括13个样本,n=4984)为元分析提供了足够的信息。荟萃分析表明,完美主义追求(r+ = 0.27,95% CI [0.21,0.32])和完美主义关注(r+ = 0.25,95% CI [0.18,0.31])与矫形厌食症有正相关关系。在控制了完美主义各维度之间的关系后,只有完美主义的追求能预测矫形厌食症,这也略微增加了完美主义的总独特效应(TUE = 0.35; 95% CI [0.28,0.42])。有初步证据表明,矫形工具调节了完美主义关注与矫形之间的关系:讨论:研究普遍发现,完美主义的两个维度都与厌食症呈正相关。需要进行更多高质量的研究来探讨解释机制,同时也要进一步收集证据,以了解由于矫形厌食症的测量方法以及其他可能的调节因素而导致的研究结果差异:证据级别:1 级,系统回顾和荟萃分析。

期刊介绍: Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity is a scientific journal whose main purpose is to create an international forum devoted to the several sectors of eating disorders and obesity and the significant relations between them. The journal publishes basic research, clinical and theoretical articles on eating disorders and weight-related problems: anorexia nervosa, bulimia nervosa, subthreshold eating disorders, obesity, atypical patterns of eating behaviour and body weight regulation in clinical and non-clinical populations.
