Reliability and validity testing of the ASSIST Functional Performance Index (AFPI) was conducted, focusing on persons with physical disabilities (PwPD). The AFPI was iteratively developed to assess persons' needs for Mainstream Smart Home Technologies (MSHT) as Assistive Technology (AT) and to measure the impact of a service delivery model for MSHT. The AFPI consists of 46 items organized by functional domains. A total of = 22 PwPD completed the AFPI twice. The median response time between these two time points was four days. Test-retest reliability of overall scores was assessed using the Intraclass Correlation Coefficient model (ICC, 3.1). The weighted kappa coefficient was applied to conduct an item analysis, demonstrating moderate to substantial agreement in all but one of the items. During the second administration, validity was established by correlating the number of hours of assistance and total AFPI scores with the SCI-FI Self-Care and Basic Mobility Short Form Questionnaires. Results indicate that the AFPI demonstrates good to very good validity as an assessment tool and outcome measure in recommending and evaluating the impact of MSHT for PwPD. Future studies, including more participants and persons with cognitive and sensory disabilities, may further establish the clinical utility of the AFPI.
针对身体残疾人士开展了辅助功能表现指数（AFPI）的信效度测试。AFPI经过反复开发，用于评估人们对主流智能家居技术（MSHT）作为辅助技术（AT）的需求，并衡量MSHT服务提供模式的影响。AFPI由按功能领域组织的46个项目组成。共有22名身体残疾人士完成了两次AFPI测试。这两个时间点之间的中位响应时间为四天。使用组内相关系数模型（ICC，3.1）评估总分的重测信度。应用加权kappa系数进行项目分析，结果显示除一项外，所有项目的一致性为中度到高度。在第二次测试期间，通过将辅助小时数和AFPI总分与SCI-FI自我护理和基本移动性简表问卷进行关联来确定效度。结果表明，AFPI作为一种评估工具和结果指标，在推荐和评估MSHT对身体残疾人士的影响方面具有良好到非常好的效度。未来的研究，包括纳入更多参与者以及认知和感官残疾人士，可能会进一步确立AFPI的临床效用。
