Abstract

Purpose: People with dementia (PWD) are one of the fastest-growing clinical populations for speech-language pathologists. Self-reported quality of life (QoL) assessments are critical patient-reported outcome measures that align with person-centered care principles. However, proxy-reporting is most often used due to assumptions that PWD cannot provide reliable self-report. Visual analog scales (VASs) have been successfully used with people with expressive and cognitive deficits to measure subjective constructs such as QoL, mood, and pain. The purpose of this project is to evaluate the feasibility and reliability of a VAS QoL assessment tool.

Methods: Twenty older adults free of cognitive impairment were assessed using the quality of life in Alzheimer's disease (QoL-AD) and the QoL-AD in combination with a VAS (VAS QoL-AD). The construct validity, internal consistency, and test-retest reliability of the VAS QoL-AD were assessed by performing both assessments twice, 4 weeks apart.

Results: Significant correlations between the overall VAS QoL-AD and the QoL-AD scale ratings, between most of the QoL-AD and VAS QoL-AD subtests, and between the first and second assessment scores were observed.

Conclusions: Results indicated strong construct validity, internal consistency, and test-retest reliability of the VAS QoL-AD in people without dementia. These results warrant further research into the development of a dementia-specific, self-reported VAS QoL scale for PWD.

自我报告生活质量的视觉模拟量表：老年人VAS和QoL AD的比较。

目的：对于语言病理学家来说，痴呆症患者是增长最快的临床人群之一。自我报告的生活质量（QoL）评估是符合以人为中心的护理原则的关键患者报告的结果测量。然而，由于假设PWD无法提供可靠的自我报告，因此最常使用代理报告。视觉模拟量表（VAS）已成功用于有表达和认知缺陷的人，以测量主观结构，如生活质量、情绪和疼痛。本项目旨在评估VAS生活质量评估工具的可行性和可靠性。方法：使用阿尔茨海默病的生活质量（QoL AD）和生活质量AD结合VAS（VAS QoL AD。VAS QoL AD的结构有效性、内部一致性和重测可靠性通过两次评估进行评估，间隔4周。结果：观察到总体VAS生活质量AD与生活质量AD量表评分之间、大多数生活质量AD和VAS生活质量-AD分测验之间以及第一次和第二次评估得分之间存在显著相关性。结论：研究结果表明，在无痴呆的人群中，VAS QoL AD具有较强的结构有效性、内部一致性和重测可靠性。这些结果值得进一步研究开发一种针对痴呆症的、自我报告的PWD VAS生活质量量表。

期刊介绍： Alzheimer Disease & Associated Disorders is a peer-reviewed, multidisciplinary journal directed to an audience of clinicians and researchers, with primary emphasis on Alzheimer disease and associated disorders. The journal publishes original articles emphasizing research in humans including epidemiologic studies, clinical trials and experimental studies, studies of diagnosis and biomarkers, as well as research on the health of persons with dementia and their caregivers. The scientific portion of the journal is augmented by reviews of the current literature, concepts, conjectures, and hypotheses in dementia, brief reports, and letters to the editor.
