Commonly used measures of instrumental activities of daily living (IADL) do not capture activities for a technologically advancing society. This study aimed to adapt the proxy/informant-based Amsterdam IADL Questionnaire (A-IADL-Q) for use in the UK and develop a self-report version.
An iterative mixed method cross-cultural adaptation of the A-IADL-Q and the development of a self-report version involving a three-step design: (1) interviews and focus groups with lay and professional stakeholders to assess face and content validity; (2) a questionnaire to measure item relevance to older adults in the U.K.; (3) a pilot of the adapted questionnaire in people with cognitive impairment.
Community settings in the UK.
One hundred and forty-eight participants took part across the three steps: (1) 14 dementia professionals; 8 people with subjective cognitive decline (SCD), mild cognitive impairment (MCI), or dementia due to Alzheimer's disease; and 6 relatives of people with MCI or dementia; (2) 92 older adults without cognitive impairment; and (3) 28 people with SCD or MCI.
The cultural relevance and applicability of the A-IADL-Q scale items were assessed using a 6-point Likert scale. Cognitive and functional performance was measured using a battery of cognitive and functional measures.
Iterative modifications to the scale resulted in a 55-item adapted version appropriate for UK use (A-IADL-Q-UK). Pilot data revealed that the new and revised items performed well. Four new items correlated with the weighted average score (Kendall's Tau -.388, -.445, -.497, -.569). An exploratory analysis of convergent validity found correlations in the expected direction with cognitive and functional measures.
The A-IADL-Q-UK provides a measurement of functional decline for use in the UK that captures culturally relevant activities. A new self-report version has been developed and is ready for testing. Further evaluation of the A-IADL-Q-UK for construct validity is now needed.
常用的工具性日常生活活动（IADL）测量方法无法捕捉到技术进步社会中的活动。本研究旨在改编基于代理人/知情者的阿姆斯特丹 IADL 问卷（A-IADL-Q），使其适用于英国，并开发一种自我报告版本。
采用迭代混合方法对 A-IADL-Q 进行跨文化适应性改编，并开发自我报告版本，设计包括三个步骤：（1）对非专业和专业利益相关者进行访谈和焦点小组讨论，以评估表面效度和内容效度；（2）一项针对英国老年人的问卷，测量项目相关性；（3）对认知障碍者进行改编问卷的试点研究。
英国的社区环境。
在三个步骤中，共有 148 人参与：（1）14 名痴呆症专业人员；8 名有主观认知减退（SCD）、轻度认知障碍（MCI）或阿尔茨海默病导致的痴呆症的人；以及 6 名 MCI 或痴呆症患者的亲属；（2）92 名无认知障碍的老年人；以及（3）28 名有 SCD 或 MCI 的人。
采用 6 点李克特量表评估 A-IADL-Q 量表项目的文化相关性和适用性。认知和功能表现采用一系列认知和功能测量来衡量。
对量表进行迭代修改，得到了适用于英国的 55 项改编版本（A-IADL-Q-UK）。初步数据显示，新修订的项目表现良好。四项新的项目与加权平均分数相关（肯德尔 tau 系数为-.388、-.445、-.497 和-.569）。探索性分析的收敛有效性发现，与认知和功能测量呈预期方向相关。
A-IADL-Q-UK 提供了一种用于英国的功能衰退测量方法，可捕捉到具有文化相关性的活动。已开发出一种新的自我报告版本，现已准备好进行测试。现在需要进一步评估 A-IADL-Q-UK 的结构有效性。
