Validation of EQ-HWB-9 among Chinese college students based on a nationwide survey.

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
objectivesThe EQ Health and Wellbeing Short Version (EQ-HWB-9) is a 9-item instrument capturing multidimensional health or well-being. This study aimed to evaluate its psychometric properties in Chinese college students-a high-risk group for mental health problems.
methodsA nationwide online cross-sectional survey was conducted across eastern, central, and western China between January and February 2025. Ceiling and floor effects of the EQ-HWB-9 were evaluated based on the response distributions of its items. Convergent validity of EQ-HWB-9 items, as well as its level sum score (LSS) and utility score was assessed according to their correlations with EQ-VAS score using Spearman correlations. Known-group validity of LSS and utility score was evaluated by comparing the mean difference and effect sizes of six pairs of college students with different status. Sensitivity of the two scores was further tested by comparing its efficiency to detect the differences with EQ-VAS score using relative efficiency (RE).
resultsA total of 3,589 college students participated in the survey, with females being 53.4% and mean age of 20.7 years. Two EQ-HWB-9 items-daily activities (75.8%) and mobility exhibited (74.6%) ceiling effects. All EQ-HWB-9 items demonstrated statistically significant correlations with the EQ-VAS score ranging from - 0.421 to -0.312, and both the EQ-HWB-9 LSS and utility score showed moderate correlations (LSS: -0.522; Utility: 0.522). Differences in mean values of LSS and utility score were statistically significant in five out of six known-groups (except for gender). The two scores generally demonstrated larger RE values compared to EQ-VAS score (LSS range: 1.049-51.590; Utility range: 0.715-61.143).
conclusionsDespite the high ceiling effect in physical-related dimensions, it appears that the EQ-HWB-9 is a valid instrument in assessing health and well-being among Chinese college student.
