ABSTRACT Background Aphasia affects approximately one-third of stroke survivors and has a significant impact on their health-related quality of life (HRQL). Aims This study assessed the psychometric properties of HRQL instruments and related constructs designed for use in people with aphasia (PWA) for use in individual clients or clinical trials, i.e., individual-level and group-level decision-making, respectively. Instruments were identified by conducting a comprehensive literature review of condition-specific, self-report measures of HRQL used in PWA. Evaluation of identified instruments was based on the 2002 Scientific Advisory Committee of the Measurement Outcomes Trust (SAC) criteria: conceptual model, burden (respondent and administrator), versatility, validity (content and construct), depth (floor and ceiling effects), reliability (internal consistency and test-retest), responsiveness and interpretability (norms and quality). SAC criteria totalled 13 for individual-level and 13 for group-level decision-making. Main contribution Most SAC criteria (%individual-level: %group-level) were met by the Assessment of Living with Aphasia (ALA) (92%:85%), followed closely by Communication Outcome after Stroke (COAST)(84%:77%) and Stroke and Aphasia Quality of Life (SAQOL-39g) (77%:77%), for instruments’ total scores. Not meeting burden and versatility criteria limited suitability of SAQOL-39g in PWA, while COAST lacked construct validity and reliability data to support its domain structure. Unmet criteria for evaluated instruments were predominantly due to unavailable data in PWA. Investigators need to continue to publish their psychometric findings in the context in which they were obtained, specifically population and setting. Conclusions Of reviewed instruments, ALA showed the most promise to measure HRQL in PWA. In instrument selection, practitioners should consider the desired construct of measurement and characteristics of the target population including aphasia severity and type. For PWA, instruments including pictures and allowing for nonverbal cues will provide broader applicability in this population.

用于评估失语症健康相关生活质量和相关结构的特定条件工具的心理测量学评估

摘要 背景 失语症影响大约三分之一的中风幸存者，并对他们的健康相关生活质量 (HRQL) 产生重大影响。目的 本研究评估了设计用于失语症 (PWA) 患者的 HRQL 工具和相关结构的心理测量特性，以用于个人客户或临床试验，即分别用于个人层面和群体层面的决策。通过对 PWA 中使用的条件特定的、自我报告的 HRQL 测量进行全面的文献回顾来确定仪器。已确定的工具的评估基于 2002 年测量结果信托科学咨询委员会 (SAC) 的标准：概念模型、负担（受访者和管理员）、多功能性、有效性（内容和结构）、深度（地板和天花板效应）、可靠性（内部一致性和重测）、响应性和可解释性（规范和质量）。个人层面的 SAC 标准共有 13 项，团体层面的决策有 13 项。主要贡献 失语症生活评估 (ALA) (92%: 85%) 满足大多数 SAC 标准（% 个人级别：% 组级别），紧随其后的是中风后交流结果 (COAST)（84%： 77%) 和中风和失语症生活质量 (SAQOL-39g) (77%:77%)，用于仪器的总分。不满足负担和通用性标准限制了 SAQOL-39g 在 PWA 中的适用性，而 COAST 缺乏结构有效性和可靠性数据来支持其域结构。未满足评估工具的标准主要是由于 PWA 中的数据不可用。调查人员需要继续在获得这些结果的背景下发布他们的心理测量结果，特别是人口和环境。结论 在审查的工具中，ALA 显示出在 PWA 中测量 HRQL 的最大希望。在工具选择中，从业者应考虑目标人群的预期测量结构和特征，包括失语症的严重程度和类型。对于 PWA，包括图片和允许非语言提示在内的工具将在该人群中提供更广泛的适用性。从业者应考虑目标人群的预期测量结构和特征，包括失语症的严重程度和类型。对于 PWA，包括图片和允许非语言提示在内的工具将在该人群中提供更广泛的适用性。从业者应考虑目标人群的预期测量结构和特征，包括失语症的严重程度和类型。对于 PWA，包括图片和允许非语言提示在内的工具将在该人群中提供更广泛的适用性。
