Perfectionism is considered a transdiagnostic construct that characterises eating disorders (EDs) and obsessive-compulsive disorder (OCD) and that could also depict orthorexia nervosa (ON). The principal aim of this study was to investigate what dimensions of perfectionism mostly represent ON. Moreover, it was evaluated if dieting impacted the presence of orthorexic features and perfectionistic behaviour. The sample consisted of two groups-the "Diet" (n = 93), and the "No Diet" (n = 94) groups-composed of people with high and low orthorexic tendencies, respectively. Participants filled out self-report questionnaires to investigate orthorexic tendencies and different facets of perfectionism. Analyses highlighted that people with high orthorexic tendencies showed higher perfectionistic features and that ON had a significant relationship with different facets of perfectionism. No interactions with diet were found. Therefore, no other differences were highlighted when the group type (Diet/No Diet) was considered. Regardless of diet, different facets of perfectionism characterise ON: perfectionism as a personality trait and perfectionism related to EDs and to obsessive-compulsive features. Our results evidenced that perfectionism could also be considered a useful construct in the conceptualization of orthorexia nervosa.
完美主义被认为是一种跨诊断的结构，它的特点是饮食失调（EDs）和强迫症（OCD），也可能描述为健康饮食强迫症（ON）。本研究的主要目的是探讨完美主义的哪些维度最能代表 ON。此外，还评估了节食是否会影响到饮食强迫症特征和完美主义行为的存在。该样本由两个组组成——“节食”（n = 93）和“非节食”（n = 94）组，分别由具有高和低饮食强迫症倾向的人组成。参与者填写了自我报告问卷，以调查饮食强迫症倾向和不同方面的完美主义。分析结果表明，具有高饮食强迫症倾向的人表现出更高的完美主义特征，而且 ON 与完美主义的不同方面有显著的关系。没有发现与饮食有关的相互作用。因此，当考虑组类型（节食/非节食）时，没有突出其他差异。无论是否节食，完美主义的不同方面都表现出饮食强迫症的特征：作为一种人格特质的完美主义，以及与饮食失调和强迫特征有关的完美主义。我们的结果表明，完美主义也可以被认为是健康饮食强迫症概念化的一个有用的结构。
