Ensuring lifelong health among aging populations necessitates comprehensive assessments of functional recovery and quality of life, particularly for vulnerable groups such as older adult stroke survivors. While the Stroke Impact Scale (SIS) 3.0 is a widely validated instrument for evaluating health-related quality of life (HRQoL) in stroke survivors, its psychometric properties have not yet been examined in the Vietnamese context. This study aimed to translate, culturally adapt, and validate the Vietnamese version of the SIS 3.0 (V-SIS 3.0), providing a robust tool to support holistic, multidimensional approaches to stroke rehabilitation in aging populations.
A cross-sectional study was conducted from July to December 2021 at the National Geriatric Hospital in Hanoi, Vietnam. The study enrolled 256 stroke survivors aged 45 years or older who had experienced a stroke between 1 month and 1 year prior to participation. The V-SIS 3.0 questionnaire was developed through a rigorous forward and backward translation process. Its factorial structure was examined using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency was assessed via Cronbach's alpha, and convergent and divergent validity were evaluated through correlation analyses. Additionally, Item Response Theory (IRT) was employed to examine item discrimination and difficulty.
EFA identified a four-factor structure consisting of Physical (28 items), Cognitive (12 items), Social Participation (10 items), and Emotional (8 items) domains. CFA supported this structure, indicating a good model fit (RMSEA = 0.080, CFI = 0.925, TLI = 0.918, SRMR = 0.053). The instrument demonstrated excellent internal consistency across all domains, with Cronbach's alpha values of 0.971 for Physical, 0.950 for Cognitive, 0.949 for Social Participation, and 0.920 for Emotional. Convergent and divergent validity were confirmed by strong item correlations within each factor, while IRT analysis further indicated high discrimination and appropriate difficulty levels for most items.
The V-SIS 3.0 is the first culturally adapted and validated tool to assess HRQoL in Vietnamese stroke survivors. By offering a reliable, multidimensional evaluation of physical, cognitive, emotional, and social wellbeing, this instrument enhances clinical assessments, informs targeted interventions, and ultimately contributes to more effective aging and lifestyle strategies for stroke survivors in Vietnam.
确保老年人群的终身健康需要对功能恢复和生活质量进行全面评估，特别是对于老年中风幸存者等弱势群体。虽然卒中影响量表（SIS）3.0是一种广泛验证的用于评估中风幸存者健康相关生活质量（HRQoL）的工具，但其心理测量特性尚未在越南背景下进行研究。本研究旨在翻译、文化调适并验证越南版的SIS 3.0（V-SIS 3.0），提供一个强大的工具来支持针对老年人群中风康复的整体、多维度方法。
2021年7月至12月在越南河内的国家老年医院进行了一项横断面研究。该研究纳入了256名年龄在45岁及以上的中风幸存者，他们在参与研究前1个月至1年之间经历了中风。V-SIS 3.0问卷通过严格的正向和反向翻译过程开发。使用探索性因子分析（EFA）和验证性因子分析（CFA）检查其因子结构。通过Cronbach's α评估内部一致性，并通过相关分析评估收敛效度和区分效度。此外，采用项目反应理论（IRT）来检查项目区分度和难度。
EFA确定了一个由身体（28个项目）、认知（12个项目）、社会参与（10个项目）和情感（8个项目）领域组成的四因素结构。CFA支持了该结构，表明模型拟合良好（RMSEA = 0.080，CFI = 0.925，TLI = 0.918，SRMR = 0.053）。该工具在所有领域都表现出出色的内部一致性，身体领域的Cronbach's α值为0.971，认知领域为0.950，社会参与领域为0.949，情感领域为0.920。每个因子内的强项目相关性证实了收敛效度和区分效度，而IRT分析进一步表明大多数项目具有高区分度和适当的难度水平。
V-SIS 3.0是首个经过文化调适并验证的用于评估越南中风幸存者HRQoL的工具。通过提供对身体、认知、情感和社会福祉的可靠、多维度评估，该工具增强了临床评估，为有针对性的干预提供信息，并最终有助于为越南中风幸存者制定更有效的衰老和生活方式策略。
