ABSTRACT

Accumulating research suggests that individuals with Mild Cognitive Impairment (MCI) experience subtle functional changes, but that available functional assessment tools are insensitive to this. To address this gap, we describe the development and validation of the self-report, “Healthy Brain Ageing Functional Assessment Questionnaire” (HBA-FAQ). We examined the factor structure and psychometric properties of the HBA-FAQ in 503 participants with normal cognition, subjective cognitive decline (SCD), MCI or dementia. Our results found the HBA-FAQ to have good reliability, validity and stronger discriminative ability between healthy control participants and those with SCD (0.734, p = .001), MCI (0.666, p = .012) and dementia (0.798, p < .001) compared to a widely-used instrumental activities of daily living screener. In conclusion, the HBA-FAQ is a valid, reliable self-report tool, providing an efficient and sensitive approach to identifying subtle changes in daily functioning in older people at risk of dementia.

越来越多的研究表明，患有轻度认知障碍（MCI）的人会经历微妙的功能变化，但现有的功能评估工具对此不敏感。为了解决这一差距，我们描述了自我报告“健康大脑老化功能评估问卷”（HBA-FAQ）的开发和验证。我们检查了 503 名认知正常、主观认知下降 (SCD)、MCI 或痴呆症参与者的 HBA-FAQ 的因素结构和心理测量特性。我们的结果发现，HBA-FAQ 在健康对照参与者与 SCD（0.734，p = .001）、MCI（0.666，p = .012）和痴呆症（0.798，p < .001）与广泛使用的日常生活工具活动筛选器相比。总之，HBA-FAQ 是一种有效、可靠的自我报告工具，提供了一种有效且敏感的方法来识别有痴呆风险的老年人日常功能的细微变化。
