• Abstract: Objective: The aim of this study was to develop a scale to measure the overweight/obesity-related quality of life and test its reliability and validity. Methods: The first draft of the scale was prepared using a literature review, a theoretical analysis, a team discussion, and expert consultation. A questionnaire survey was administered to 664 participants. The items and structure of the scale were improved using an item analysis and exploratory factor analysis. The goodness of fit between the scale and theoretical construct was verified using a confirmatory factor analysis. The scale reliability was assessed using Cronbach’s α and split-half reliability. Results: The scale for measuring the overweight/ obesity-related quality of life was comprised of 14 items in three dimensions: self, interpersonal communication and social. The cumulative contribution of the three common factors identified in the exploratory factor analysis to the variance was 73.356%, the factor loadings of the 14 items were in the range of 0.633–0.825 (a factor loading >0.4 is generally considered acceptable) , and no multiple loadings were found. The confirmatory factor analysis showed a good overall fit of the model. All of the Cronbach’s α and Guttman split-half coefficients of the individual dimensions were greater than 0.7. Conclusion: The scale for measuring the overweight/obesity-related quality of life had good reliability and validity and can be used to assess the overweight/obesity-related quality of life. 目的：编制肥胖相关生命质量量表，并对其进行信效度检验。方法：通过文献回顾、理论分析、核心小组讨论、专家咨询编制初始量表。对664位被试进行问卷调查，根据项目分析以及探索性因子分析的结果，对量表条目和结构进行优化，通过验证性因子分析验证量表与理论结构的拟合程度；通过Cronbach’sα系数、折半信度评价量表的信度。结果：肥胖相关生命质量量表，包括自我、人际交往、社会这3个维度，共14个条目。探索性因子分析得到3个公因子，累计方差贡献率为73.356%，且14个条目因子载荷范围为0.633～0.825，均>0.4，无多重载荷。验证性因子分析显示模型整体拟合较好。量表各维度及总体的Cronbach’sα系数和Guttman折半系数均大于0.7。结论：构建的肥胖相关生命质量量表具有良好的信效度，可以用于评估居民肥胖相关生命质量水平。
