Technologies for ageing in place may help older adults in their homes to overcome multiple impairments and to promote their autonomy and independence. When conceptualizing technologies for ageing in place, the International Classification of Functioning, Disability and Health (ICF) is a key element due to its functioning and disability framework with consolidated concepts and terminologies. Based on the ICF conceptual framework, the article presents the ICF based Usability Scale (ICF-US) to evaluate the usability of technologies for ageing in place and reports a study aiming: (1) to validate the ICF-US to evaluate usability according to the evaluators’ perspective about the users’ performance and (2) to evaluate the utility and applicability of the ICF-US. Two observational studies evolving 184 participants were conducted to: (1) assess the validity and reliability of the ICF-US to evaluate usability according to the evaluators’ perspective about the users’ performance and (2) to verify the utility and applicability of the ICF-US. The results suggest that the ICF-US is valid and reliable and can be used in different stages of technological developments without losing its discriminatory capacity.

根据评估者对用户绩效的看法验证可用性评估工具

适当的老化技术可以帮助老年人在家中克服多种障碍，并促进他们的自主权和独立性。在概念化老化技术时，功能，残疾和健康国际分类（ICF）是一个关键要素，因为它具有统一的概念和术语的功能和残疾框架。在ICF概念框架的基础上，本文提出了基于ICF的可用性量表（ICF-US），用于评估就地老化技术的可用性，并报告了一项研究目标：（1）验证ICF-US根据以下条件评估可用性评估者对用户性能的看法；（2）评估ICF-US的实用性和适用性。进行了两项观察研究，涉及184名参与者，以期：（1）根据评估者对用户性能的看法，评估ICF-US的有效性和可靠性，以评估可用性；以及（2）验证ICF-US的实用性和适用性。结果表明，ICF-US是有效和可靠的，可以在技术发展的不同阶段使用，而不会失去其区分能力。
