Cultural adaptation and psychometric evaluation of the CHU-9D in Hong Kong adolescents.

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
objectiveThis study aimed to perform a cultural adaptation of the Child Health Utility 9D (CHU-9D), a health-related quality of life (HRQoL) instrument, into Traditional Chinese specifically for use in Hong Kong, and evaluating its psychometric properties among a sample of local adolescents.
methodsA cross-sectional survey design was employed for data collection. Adolescents aged 13 to 17 years were recruited from diverse local community settings to complete a self-administered questionnaire that included the adapted CHU-9D and relevant demographic items. Psychometric evaluations encompassed assessments of ceiling and floor effects, factorial validity through confirmatory factor analysis, convergent validity via correlation analysis, and known-group validity to examine differences across predefined risk groups.
resultsA total of 627 adolescents successfully completed the survey, providing a robust dataset for analysis. The unidimensionality of the CHU-9D was confirmed, demonstrating excellent model fit indices. A ceiling effect was observed, with 27% of participants reporting full health status on the CHU-9D descriptive system, indicating potential limitations in capturing variations at the upper end of health. Convergent validity was supported by significant correlations between CHU-9D and conceptually relevant items and subscales from another HRQoL instrument. The instrument exhibited strong known-group validity, effectively discriminating HRQoL differences across various risk groups with statistically significant results.
conclusionThe culturally adapted Traditional Chinese version of the CHU-9D demonstrates sound psychometric properties in Hong Kong adolescents, supporting it as a valid tool for measuring and valuing HRQoL in this population and cultural context.
