Key result
Chinese WEMWBS reliably measures mental well-being in patients with HF or MI.
Why the study?
Positive mental well-being is important in cardiovascular care, but validated Chinese-language instruments for assessing it in patients with heart failure or myocardial infarction remain limited.
Cross-Sectional (n=392)
Yes
Effect estimate: r = 0.746 (95% CI 0.722-0.794)
p-value: p=<0.01
The Chinese-language WEMWBS demonstrated satisfactory psychometric properties, supporting its potential use as a patient-reported outcome measure for assessing positive mental well-being in patients with heart failure or myocardial infarction.
Supports well-being assessment in Chinese HF/MI patients; extends validation but leaves open outcome prediction.
Background: Positive mental well-being is increasingly recognized as an important component of cardiovascular care, particularly among patients with heart failure or myocardial infarction. However, validated Chinese-language instruments for assessing positive mental well-being in this population remain limited. Objective: This study evaluated the psychometric properties of the Chinese-language 14-item Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) in patients with heart failure or myocardial infarction. Methods: In this cross-sectional validation study, 392 patients with heart failure or myocardial infarction completed the Chinese-language WEMWBS. Construct validity was examined using exploratory and confirmatory factor analyses. Convergent validity was assessed using factor loadings, composite reliability (CR), and average variance extracted (AVE), and criterion-related validity was evaluated using the 5-item World Health Organization Well-Being Index (WHO-5) as an external criterion. Internal consistency was estimated using Cronbach's α. Item-level performance was examined using item response theory under the graded response model. Results: The Chinese-language WEMWBS showed excellent internal consistency, with Cronbach's α = 0.961. The modified one-factor confirmatory factor model showed acceptable fit on most indices, with χ²/df = 2.68, CFI = 0.955, TLI = 0.944, RMSEA = 0.091, and SRMR = 0.038. Criterion-related validity was supported by a strong positive correlation with the WHO-5 (r = 0.746). Item response theory analyses indicated generally satisfactory item discrimination and ordered threshold parameters. Conclusions: The Chinese-language WEMWBS demonstrated satisfactory psychometric properties in patients with heart failure or myocardial infarction. These findings support its potential use as a patient-reported outcome measure for assessing positive mental well-being in this population. Longitudinal and intervention studies are needed to evaluate its responsiveness, predictive validity, and clinical utility in cardiovascular care.

Tang et al. (2026) conducted a cross-sectional in Heart failure or myocardial infarction (n=392). Chinese Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) was evaluated on Criterion-related validity (correlation with WHO-5) (r = 0.746, 95% CI 0.722-0.794, p=<0.01). The Chinese-language WEMWBS demonstrated excellent internal consistency (Cronbach's α = 0.961) and strong criterion-related validity (r = 0.746) in patients with heart failure or myocardial infarction.
