Abstract

Cognitive models of obsessive-compulsive disorder (OCD) postulate that dysfunctional beliefs and appraisals are key elements in the development and maintenance of obsessions. Given the relationship between the orthorexia nervosa (OrNe), OCD, and eating disorders, it is not surprising that some dysfunctional beliefs are present in OrNe. The aim of this research was to determine the relevance of dysfunctional beliefs in OrNe. To do so, we developed and validated an instrument that assesses these beliefs –the Orthorexia Beliefs Scale (OBS)– and, subsequently, analyzed the association between orthorexia, food restriction, obsessive-compulsive symptoms, and negative/positive affect, along with the beliefs evaluated with the OBS. Participants (n = 418) were given a set of questionnaires. We expected the obtained instrument to be able to assess dysfunctional beliefs related to orthorexia and establish positive associations between pathological dimensions and OrNe. The results revealed that the scale evaluated three factors: Overvaluation of Healthy Eating, Moral Meaning, and Need to Control. OrNe was significantly associated with all three of these factors and the most relevant association was with the Need to Control factor. An association between the non-pathological variable of orthorexia (HeOr) and the Overvaluation of Healthy Eating factor was also found. The results seem to indicate that the dysfunctionality of orthorexia is highly marked by the need to control, as also occurs in eating disorders.

矫正信念在神经性矫正饮食和健康矫正饮食中起什么作用？正食信念量表（OBS）的编制与验证

强迫症（OCD）的认知模型假定，功能失调的信念和评价是强迫症发展和维持的关键因素。鉴于神经性厌食症（OrNe）、强迫症和进食障碍之间的关系，OrNe 中存在一些功能失调信念也就不足为奇了。本研究旨在确定功能失调信念与神经性厌食症的相关性。为此，我们开发并验证了一种评估这些信念的工具--厌食症信念量表（OBS），随后分析了厌食症、食物限制、强迫症状、消极/积极情绪与 OBS 评估的信念之间的关联。我们向参与者（n = 418）发放了一套问卷。我们期望所获得的工具能够评估与厌食症有关的功能失调信念，并在病理维度和 OrNe 之间建立正相关。结果显示，量表评估了三个因素：高估健康饮食、道德意义和控制需求。OrNe与这三个因素都有明显的关联，其中与控制需求因素的关联最大。此外，还发现厌食症的非病理性变量（HeOr）与高估健康饮食因素之间存在关联。这些结果似乎表明，厌食症的功能障碍在很大程度上表现为需要控制，饮食失调症也是如此。

期刊介绍： Appetite is an international research journal specializing in cultural, social, psychological, sensory and physiological influences on the selection and intake of foods and drinks. It covers normal and disordered eating and drinking and welcomes studies of both human and non-human animal behaviour toward food. Appetite publishes research reports, reviews and commentaries. Thematic special issues appear regularly. From time to time the journal carries abstracts from professional meetings. Submissions to Appetite are expected to be based primarily on observations directly related to the selection and intake of foods and drinks; papers that are primarily focused on topics such as nutrition or obesity will not be considered unless they specifically make a novel scientific contribution to the understanding of appetite in line with the journal's aims and scope.
