摘要
目的:神经性厌食症(ON)是一种描述强迫性关注 "健康 "饮食的疾病,其特征是症状与强迫症重叠。然而,有关厌食症/强迫症(OC)症状关系的报道并不一致。本研究旨在调查 OC 症状和信念是否能解释 ON 症状的变异,并确定完美主义这一跨诊断因素是否能调节 ON/OC 症状的关系:本研究通过本科生研究计划、社交媒体、宣传机构和参与者登记处招募了190名参与者(平均年龄=28.63岁,平均年龄差值=9.88岁;80%为女性)。参与者填写了一份在线调查问卷,对ON、OC和完美主义症状进行评估:线性回归分析发现,OC 症状和信念解释了 ON 症状 22.9% 的变异性(p 2 = 0.38),完美主义调节了 ON/OC 症状的关系,完美主义水平越高,OC 症状水平越高,则 ON 症状水平越高,解释了 2.2% 的变异性(p = 0.01,f2 = 0.03):结论:OC 症状在 ON 中似乎比以往研究显示的更为常见。然而,完美主义和强迫症状之间的相互作用可能会导致强迫症。研究结果有助于完善我们目前对ON现象学的理解,并对ON治疗的发展产生影响。未来的研究应进一步探讨完美主义在ON现象学中的应用:证据级别:V级(权威人士的观点,基于描述性研究、叙述性综述、临床经验或专家委员会的报告)。
Perfectionism as a moderator of the relationship between orthorexia nervosa and obsessive-compulsive symptoms.
Purpose: Orthorexia nervosa (ON), a proposed disorder describing an obsessive focus on "healthy" eating, is characterised as having overlapping symptoms with obsessive-compulsive disorder. However, ON/obsessive-compulsive (OC) symptom relationships are inconsistently reported. The current study aimed to investigate if the contribution of OC symptoms and beliefs explain variability in ON symptoms and determine if perfectionism, a transdiagnostic factor, moderates the ON/OC symptom relationship.
Methods: The study comprised 190 participants (Mage = 28.63, SDage = 9.88; 80% female) recruited via an undergraduate research programme, social media, advocacy organisations, and a participant registry. Participants completed an online questionnaire assessing ON, OC, and perfectionism symptoms.
Results: A linear regression analysis found OC symptoms and beliefs explained 22.9% variability in ON symptoms (p < 0.001, f2 = 0.38) and perfectionism moderated the ON/OC symptom relationship, where higher levels of perfectionism with higher levels of OC symptoms was associated with higher levels of ON symptoms, explaining 2.2% variability (p = .01, f2 = 0.03).
Conclusion: OC symptoms appear more common in ON than previous studies indicate. However, the interaction between perfectionism and OC symptoms may drive obsessions in ON. Findings help refine our current understanding of ON phenomenology with implications for ON treatment development. Future research should further explore perfectionism in ON phenomenology.
Level of evidence: Level V (Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees).
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.
