To develop a web-based food-frequency questionnaire (FFQ) measuring intake of plant-based protein foods (PBP) among older adults from the province of Quebec, Canada.
The questionnaire was adapted from an existing self-administered FFQ and first underwent expert panel evaluation for face and content validity. Then, three phases of cognitive testing were conducted in French, using the probe and think aloud approaches. Between each phase, the questionnaire was modified based on participants' feedback to improve the clarity and comprehension of the questions.
Quebec City, Quebec, Canada.
Twenty adults aged 65 years and older participated. Purposive sampling was used to maximise variation in sociodemographic characteristics, including gender, age, education level and PBP consumption.
The expert panel found the twenty-eight-item questionnaire to be a comprehensive measure of PBP intake and suggested minor changes to improve its clarity. The cognitive interviews showed that our PBP-FFQ was generally well understood and identified issues requiring modifications to improve comprehension and accuracy.
Our FFQ provides a comprehensive measure of PBP intake, is well understood by older adults in Québec and will support rigorous assessment of PBP intake in this population but requires further validation to confirm its validity and reproducibility.
开发一个基于网络的食物频率问卷（FFQ），用于测量加拿大魁北克省老年人的植物性蛋白质食物（PBP）摄入量。
该问卷改编自现有的自填式FFQ，首先进行专家小组评估以检验其表面效度和内容效度。然后，使用探测法和出声思考法用法语进行了三个阶段的认知测试。在每个阶段之间，根据参与者的反馈对问卷进行修改，以提高问题的清晰度和可理解性。
加拿大魁北克省魁北克市。
20名65岁及以上的成年人参与。采用目的抽样法，以最大限度地增加社会人口学特征的差异，包括性别、年龄、教育水平和PBP摄入量。
专家小组发现这份包含28个条目的问卷是对PBP摄入量的全面测量，并建议进行一些小的修改以提高其清晰度。认知访谈表明，我们的PBP-FFQ总体上易于理解，并发现了需要修改的问题，以提高理解度和准确性。
我们的FFQ提供了对PBP摄入量的全面测量，魁北克的老年人易于理解，将有助于对该人群的PBP摄入量进行严格评估，但需要进一步验证以确认其效度和可重复性。
