Optimizing health-related quality of life assessments for stroke survivors: a validation study of psychometric properties for the Vietnamese version of stroke impact scale 3.0.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: 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. Methods: 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. Results: 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. Conclusion: 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.
