Valid and reliable measures are needed to identify individuals at risk of dietary restraint, emotional and external eating, and to customize weight loss education for more effective weight management. This study aimed to develop and validate a Chinese version of the Weight-Related Eating Behavior Questionnaire (WREQ-C) for assessing dietary restraint, emotional eating, and external eating. In stage one, the linguistic validation of the original English version of the WREQ (WREQ-E) was conducted. In stage two, the psychometric properties of the WREQ-C were first evaluated by item response theory-based (IRT) analyses. The reduced scale was then examined for convergent validity, structural validity (using a confirmatory factor analysis), population invariance, and test-retest reliability. The study included 1007 adults aged between 18 and 71 years. The IRT analysis optimally shortened the original WREQ-E from 16 to 13 items. A convergent validity analysis showed significant correlations between the WREQ-C subscales and the Chinese version of the Dutch Eating Behavior Questionnaire subscales ( = 0.63-0.82). The 13-item WREQ-C demonstrated good reliability (Cronbach's α = 0.74-0.89) and validity for assessing the psychological aspects of eating behavior, including routine restraint, compensatory restraint, susceptibility to external cues, and emotional eating in Chinese adults.
需要有效的、可靠的手段来识别有节食、情绪性进食和外食倾向的个体，并为更有效的体重管理定制减肥教育。本研究旨在开发和验证中文版的体重相关进食行为问卷（WREQ-C），以评估节食、情绪性进食和外食倾向。在第一阶段，对 WREQ-E 的英文原版进行了语言验证。在第二阶段，首先基于项目反应理论（IRT）分析评估了 WREQ-C 的心理测量特性。然后，对简化后的量表进行了收敛效度、结构效度（使用验证性因素分析）、人群不变性和重测信度的检验。该研究纳入了 1007 名年龄在 18 岁至 71 岁之间的成年人。IRT 分析将原始的 WREQ-E 从 16 项优化为 13 项。收敛效度分析显示，WREQ-C 分量表与中文版荷兰饮食行为问卷分量表之间存在显著相关性（ = 0.63-0.82）。13 项 WREQ-C 对评估中国成年人进食行为的心理方面具有良好的信度（Cronbach's α = 0.74-0.89）和效度，包括常规节食、补偿性节食、对外界线索的易感性和情绪性进食。
