Understanding patients' motives for undergoing metabolic and bariatric surgery (MBS) is key to managing postoperative expectations. We aimed to translate and validate the 14-item European Obesity Academy Questionnaire on Expectations about Surgical Treatment (EOAQ-EST) to Brazilian Portuguese for research and clinical use.
This study included a total of 198 candidates for MBS at a reference academic hospital in Brazil from January 2021 to February 2022. We followed Beaton and Bombardier's guidelines for translation and cultural adaptation, including translation, back-translation, comparative analysis, expert review, pilot testing, and the creation of the final version of the questionnaire. Reliability was tested with McDonald's omega, and internal validity was assessed using confirmatory factor analysis (CFA).
The final version was applied to 161 patients, 85% female, with a mean age of 46.4 ± 10.3 years and a mean BMI of 48.3 ± 8.2 kg/m. Validity was supported by a bifactorial model (95% CI 0.044-0.104, p = 0.08), excluding one item (improved fertility) due to a floor effect. The reliability analysis showed that the 13 remaining items were internally consistent, with a McDonald's ω of 0.625.
The Brazilian-Portuguese version of EOAQ-EST proved to be user-friendly, consistent, and reliable. This questionnaire may assist multidisciplinary teams in effectively addressing patients' expectations concerning metabolic and bariatric surgery (MBS) outcomes.
了解患者接受代谢和减重手术（MBS）的动机对于管理术后预期至关重要。我们旨在将欧洲肥胖学会关于手术治疗期望的 14 项问卷（EOAQ-EST）翻译并验证为巴西葡萄牙语，用于研究和临床用途。
本研究共纳入了 2021 年 1 月至 2022 年 2 月期间巴西一家学术参考医院的 198 名 MBS 候选者。我们遵循了 Beaton 和 Bombardier 的翻译和文化适应指南，包括翻译、回译、比较分析、专家审查、试点测试和问卷的最终版本的创建。使用 McDonald 的 ω进行了可靠性测试，使用验证性因素分析（CFA）评估了内部有效性。
最终版本应用于 161 名患者，85%为女性，平均年龄为 46.4±10.3 岁，平均 BMI 为 48.3±8.2 kg/m。有效性得到了双因素模型的支持（95%CI 0.044-0.104，p=0.08），排除了一个由于地板效应的项目（改善生育能力）。可靠性分析表明，13 个剩余项目具有内部一致性，McDonald 的 ω为 0.625。
巴西葡萄牙语版的 EOAQ-EST 证明了其易用性、一致性和可靠性。该问卷可以帮助多学科团队有效地解决患者对代谢和减重手术（MBS）结果的期望。
