目的：在临床和非临床人群中，不适应运动与进食障碍（ED）的病理和损害有关。目前，与ED病理相关的两种不同的运动适应不良概念经常被研究：强迫性运动和运动依赖。强迫性运动的功能是避免与不运动相关的负面影响（如内疚和焦虑），而运动依赖则与对运动益处的耐受性和对运动退出的避免有关。目前，临床医生和研究人员努力确定最合适的术语来描述ED病理个体的问题运动。本研究旨在直接比较这些与ED病理严重程度有关的适应性不良运动的概念。设计：本研究检查了横断面数据。方法：ED病理升高的大学生（235例，女性78%）完成了进食障碍检查问卷（ED - q）、强迫运动测试（CET）和运动依赖量表（EDS）。多元线性回归分析评估了ed - q与CET和EDS得分之间的关联，优势分析确定了哪些运动质量与ed - q得分之间的唯一关联。结果：结果表明，强迫性运动，包括控制体型和体重以及避免负面影响的运动，与运动依赖的质量相比，与ED病理严重程度的关系更强。结论：与ED人群一起工作的临床医生和研究人员可以从捕获强迫性运动品质的优先评估中获益。此外，这些结果表明，有效针对其他强迫行为的干预措施（例如，暴露和反应预防）可能是ed背景下有问题的运动的有希望的治疗选择。
Objective: Maladaptive exercise relates to eating disorder (ED) pathology and impairment in clinical and non-clinical populations. At present, two different conceptualizations of maladaptive exercise are often studied in relation to ED pathology: compulsive exercise and exercise dependence. Compulsive exercise functions to avoid negative affect (e.g., guilt and anxiety) associated with not exercising, whereas exercise dependence is associated with tolerance to exercise benefits and avoidance of exercise withdrawal. At present, clinicians and researchers struggle to determine the most appropriate term for describing problematic exercise in individuals with ED pathology. This study aimed to directly compare these conceptualizations of maladaptive exercise in relation to severity of ED pathology.Design: This study examined cross-sectional data.Method: Undergraduate participants (N = 235, 78% female) with elevated ED pathology completed the Eating Disorder Examination Questionnaire (EDE-Q), Compulsive Exercise Test (CET), and Exercise Dependence Scale (EDS). Multiple linear regression analyses evaluated associations between EDE-Q and CET and EDS scores and dominance analysis determined which qualities of exercise were uniquely associated with EDE-Q scores.Results: Results suggest that compulsive qualities of exercise, including exercise to control shape and weight and to avoid negative affect are more strongly associated with severity of ED pathology than qualities of exercise dependence.Conclusions: Clinicians and researchers working with ED populations can benefit from prioritizing assessments that capture compulsive qualities of exercise. Additionally, these results suggest that interventions that effectively target other compulsive behaviors (e.g., exposure and response prevention) may be promising treatment options for problematic exercise in the context of EDs.
