Abstract:

Objective To translate the Eating Behaviors Assessment for Obesity（EBA-O） and test its reliability and validity for providing an effective tool for brief and rapid clinical assessment of dietary behavior in obese patients. Methods The Chinese version of EBA-O was developed by Brislin’s translation model for translation，back translation，cultural adaptation，and pilot investigation. Using convenience sampling method，200 obese patients who were admitted to the inpatient ward of the Weight Loss Center of a tertiary hospital in Beijing from April to June 2023 and planned to undergo weight loss metabolic surgery were selected as the research participants to test the reliability and validity of the Chinese version of EBA-O. Results The Chinese version of EBA-O includes 4 dimensions，with a total of 17 items. The Cronbach’s α coefficient of the scale is 0.886；the Cronbach’s α coefficients of the dimensions are 0.770~0.866；the test-retest reliability of the scale is 0.881. The content validity index of the scale level is 0.980，and the content validity indexes of item level were 0.889~1.000. Totally 4 common factors were extracted through exploratory factor analysis，with a cumulative variance of 66.363%. Conclusion The Chinese version of EBA-O has good reliability and validity，and it can be used as a tool to evaluate the dietary behavior of obese patients undergoing weight loss metabolic surgery.

摘要：

目的 汉化肥胖患者饮食行为评估量表（Eating Behaviors Assessment for Obesity，EBA-O）并进行信效度检验，为临床简单快速地评估肥胖患者饮食行为提供测评工具。方法 采用Brislin的翻译模型，对EBA-O进行翻译、回译、文化调适和预调查后，形成中文版EBA-O。采用方便抽样法，选取2023年4月—6月北京市某三级甲等医院减重中心收治的200例拟行减重手术的肥胖患者为调查对象，以检验中文版EBA-O的信效度。结果 中文版EBA-O包括4个维度，共17个条目，量表的Cronbach’s α系数为0.886，各维度的Cronbach’s α系数为0.770~0.866，重测信度为0.881，量表水平的内容效度指数为0.980，条目水平的内容效度指数为0.889~1.000，通过探索性因子分析提取出4个公因子，累计方差贡献率为66.363%。结论 中文版EBA-O具有良好的信效度，可作为评估肥胖患者饮食行为的工具。
