摘要: 背景 减重代谢术后患者的放牧饮食行为与术后复胖明显相关,且其发生率会随术后时间的延长而不断增加,对减重代谢术后患者放牧饮食行为进行早期发现和准确评估尤为重要。目前,国内尚缺乏针对减重代谢术后患者放牧饮食行为的量性测评工具。 目的 对放牧饮食行为测评量表〔Rep(eat)-Q〕进行汉化,并在减重代谢术后患者中验证其信效度。 方法 按照Brislin翻译模型,通过翻译、回译、专家评议和预试验后,确定Rep(eat)-Q中文版终稿。于2022-08-31,采用方便抽样法,选取2022年3—8月南京医科大学第一附属医院减重随访门诊收治的减重代谢术后患者为研究对象。采用一般资料调查表、Rep(eat)-Q中文版、三因素饮食量表(TFEQ)-R21对294例减重代谢术后患者进行调查,检验Rep(eat)-Q中文版的信效度。 结果 利用临界比值法将受试者分为高分组(79例)和低分组(78例),高分组Rep(eat)-Q中文版各条目得分均明显高于低分组(P<0.05)。Rep(eat)-Q中文版中各条目得分与总分均呈线性正相关(r值为0.368~0.782,P<0.05)。Rep(eat)-Q中文版、非强迫型、强迫型放牧饮食维度的Cronbach's α系数分别为0.943、0.928、0.898,折半信度分别为0.835、0.938、0.891,重测信度分别为0.867、0.800、0.836。量表各条目的内容效度指数为0.80~1.00,总量表的全体一致内容效度指数为0.92,平均内容效度指数为0.98。采用主成分分析法,经最大方差旋转后提取2个公因子,特征值分别为8.069、1.219,累积方差贡献率为77.40%,各条目因子载荷值为0.637~0.878;验证性因子分析显示,拟合优度卡方检验(χ2/df)为2.211,拟合优度指数(GFI)为0.905,调整后的拟合优度指数(AGFI)为0.860,规范拟合指数(NFI)为0.920,增值拟合指数(IFI)为0.955,比较拟合指数(CFI)为0.954,近似误差均方根(RMSEA)为0.080。294例调查对象Rep(eat)-Q中文版总得分与TFEQ-R21的各维度得分存在明显相关性(P<0.05)。 结论 Rep(eat)-Q中文版信效度较好、简单易行,可为我国减重代谢术后患者的放牧饮食行为提供可靠的测评工具。

Abstract:

Background

The grazing behavior after bariatric surgery is significantly related to postoperative weight regain, and its incidence will increase with the extension of time after surgery. So it is particularly important to early detect and accurately evaluate the grazing behavior of patients undergoing bariatric surgery. At present, the assessment tools for grazing behavior in these patients in China are still lacking.

Objective

To translate the Repetitive Eating Questionnaire〔Rep (eat) -Q) 〕into Chinese and evaluate its reliability and validity among patients undergoing bariatric surgery.

Methods

The Brislin's model of translation was adopted for translation. We developed the Chinese version of Rep (eat) -Q following the process of translation of the English version of the Rep (eat) -Q, back translation, expert review and a pilot study. On 2022-08-31, patients undergoing bariatric surgery admitted to the bariatric follow-up clinic of the First Affiliated Hospital with Nanjing Medical University from March to August 2022 were selected for the study using convenience sampling. Then we used the general information questionnaire, Chinese version of Rep (eat) -Q and the 21-item Three-Factor Eating Questionnaire (TFEQ-R21) to conduct a survey among 294 patients undergoing bariatric surgery to test the reliability and validity of the Chinese version of Rep (eat) -Q.

Results

According to the score of the Chinese version of Rep (eat) -Q, these patients were divided into high-score group (n=79) and low-score group (n=78) by the critical ratio. High-score group scored higher in each item of the Chinese version of Rep (eat) -Q compared with the low-score group (P<0.05) . The score of each item in the Chinese version of Rep (eat) -Q was linear positively correlated with the total score (r=0.368-0.782, P<0.05) . The value of Cronbach's α for the scale, repetitive eating subscale and compulsive grazing subscale was 0.943, 0.928 and 0.898, respectively. The value of split-half reliability for the scale, repetitive eating subscale and compulsive grazing subscale was 0.835, 0.938 and 0.891, respectively. And the value of test-retest reliability of the scale, repetitive eating subscale and compulsive grazing subscale was 0.867, 0.800, and 0.836, respectively. The item-level content validity index (CVI) ranged from 0.80 to 1.00. The scale-level CVI /universal agreement and S-CVI/average were 0.92 and 0.98, respectively. Two common factors were obtained after varimax orthogonal rotation by principal component analysis, whose eigenvalues were 7.086, and 1.596, respectively, explaining 72.35% of the total variance. The factor loading values of all items ranged 0.637 to 0.878. The confirmatory factor analysis indicated that the values ofχ2/df, GFI, AGFI, NFI, IFI, CFI and RMSEA were 2.211, 0.905, 0.860, 0.920, 0.955, 0.954, and 0.080, respectively. 294 patients' total score of the Chinese version of Rep (eat) -Q showed a significant correlation with three dimensions of the TFEQ-R21 (P<0.05) .

Conclusion

The Chinese version of Rep (eat) -Q has good reliability and validity, and is simple and easy-to-operate, which can be used to assess the grazing behavior among Chinese patients undergoing bariatric surgery.
