Abstract：
This study aims to develop and validate the content and response processes of a questionnaire intended for caregivers to screen for dysphagia in Brazilian older adults with dementia due to Alzheimer\'s disease and/or vascular dementia. The instrument items were developed in Brazilian Portuguese language based on the theoretical framework. A committee of speech-language-hearing therapists analyzed the relevance, objectivity, clarity, and understandability of the items with the Delphi method. The content validity index cutoff agreement score for experts\' answers to validate each item in the questionnaire was 0.78; in the intraclass correlation coefficient, it was 0.75 for all items. For response process validity evidence, the questionnaire was applied to 30 caregivers of older adults with dementia, who judged the clarity and understandability of the items. Each item was validated when understood by at least 95% of participants. The first version of the instrument had 29 items. After two expert assessments, the last version had 24 items. The intraclass correlation coefficient was 0.85. Only one item needed semantic adjustments in the pre-test. The dysphagia screening instrument applied to caregivers of older adults with dementia was developed with adequate content and response process validity evidence, enabling adjustments in its construct. Future studies will analyze the remaining evidence of validity and reliability.
摘要：
这项研究旨在开发和验证问卷的内容和反应过程，该问卷旨在让护理人员筛查巴西老年人因阿尔茨海默氏病和/或血管性痴呆引起的吞咽困难。文书项目是根据理论框架以巴西葡萄牙语开发的。一个由言语-语言-听力治疗师组成的委员会分析了这种相关性，客观性,清晰度,和项目的可理解性与Delphi方法。专家回答验证问卷中每个项目的内容效度指数截止一致性分数为0.78；在组内相关系数中，所有项目都是0.75。对于响应过程有效性证据，问卷被应用于30名患有痴呆症的老年人的照顾者，谁判断项目的清晰度和可理解性。当至少95%的参与者理解时，每个项目都经过验证。该仪器的第一个版本有29个项目。经过两次专家评估，最后一个版本有24个项目。组内相关系数为0.85。在预测试中只有一项需要语义调整。开发了适用于痴呆症老年人护理人员的吞咽困难筛查工具，具有足够的内容和反应过程有效性证据，能够调整其结构。未来的研究将分析效度和信度的剩余证据。
