    The study evaluated the psychometric properties of the Chinese-language Warwick–Edinburgh Mental Well-Being Scale (WEMWBS) in patients with heart failure or myocardial infarction.

  • 2

    A total of 392 patients completed the Chinese-language WEMWBS, which demonstrated excellent internal consistency with a Cronbach’s α of 0.961.

  • 3

    The modified one-factor confirmatory factor model of the WEMWBS showed acceptable fit indices, indicating good construct validity.

  • 4

    Criterion-related validity was supported by a strong positive correlation between the WEMWBS and the WHO-5 Well-Being Index (r = 0.746).

  • 5

    Item response theory analyses indicated satisfactory item discrimination and ordered threshold parameters for the Chinese-language WEMWBS.
