For people with anorexia nervosa (AN), compulsive exercise is characterized by extreme concerns about the perceived negative consequences of stopping/reducing exercise, dysregulation of affect, and inflexible exercise routines. It is associated with increased eating disorder psychopathology and poor clinical outcome. However, its relationships with two important clinical issues, quality of life (QoL) and motivation to change, are currently unknown. This study aimed to assess the cross-sectional relationships between compulsive exercise, QoL, psychological distress (anxiety and depressive symptoms, and obsessive-compulsive traits) and motivation to change in patients with AN.
A total of 78 adults with AN participated in this study, which was nested within a randomized controlled trial of psychological treatments for AN. At baseline (pre-treatment), participants completed questionnaires assessing compulsive exercise, eating disorder (ED) psychopathology, QoL, psychological distress and motivation to change.
Baseline correlational analyses demonstrated a moderate positive relationship between compulsive exercise and ED psychopathology, and a weak positive relationship between compulsive exercise and psychological distress. There was a moderate negative relationship between compulsive exercise and eating disorder QoL.
These results indicate compulsive exercise is moderately associated with poorer QoL and weakly associated with higher distress. Targeting compulsive exercise in the treatment of anorexia nervosa may help reduce the burden of illness and improve patients' engagement in treatment.

对于神经性厌食症（AN）患者，强迫性运动的特征是极度担心停止/减少运动所带来的负面后果、情绪失调以及僵化的运动习惯。它与饮食失调心理病理学的加重和不良临床结局相关。然而，其与两个重要临床问题，即生活质量（QoL）和改变动机之间的关系目前尚不清楚。本研究旨在评估AN患者中强迫性运动、QoL、心理困扰（焦虑和抑郁症状以及强迫特质）与改变动机之间的横断面关系。
共有78名成年AN患者参与了本研究，该研究嵌套于一项针对AN的心理治疗随机对照试验中。在基线（治疗前）时，参与者完成了评估强迫性运动、饮食失调（ED）心理病理学、QoL、心理困扰和改变动机的问卷。
基线相关性分析表明，强迫性运动与ED心理病理学之间存在中度正相关，与心理困扰之间存在弱正相关。强迫性运动与饮食失调QoL之间存在中度负相关。
这些结果表明，强迫性运动与较差的QoL中度相关，与较高的困扰弱相关。在神经性厌食症治疗中针对强迫性运动可能有助于减轻疾病负担并提高患者对治疗的参与度。
