Development and Validation of a Health Literacy Scale for Patients With Cardiovascular Disease (HLS-CVD).
Jeongeun Sim, Seon Young Hwang
PMID 41995383WHAT IT FOUND
A 22-item scale for patients with cardiovascular disease was tested in 391 patients in Korea.
It covers understanding, using, and discussing health information, but it was not tested against patient outcomes.
Key findings
01The final HLS-CVD has 22 items scored on a 4-point scale, with total scores from 22 to 88.
02The 22-item scale was tested in 391 patients and had Cronbach's alpha 0.891.
03In a 50-person subsample, scores were stable over 2 weeks, with an intraclass correlation of 0.843.

What it does not show
The sample came from two tertiary-care hospitals in Korea and was a convenience sample, so it may not represent patients elsewhere. The study was done during the coronavirus pandemic, which limited institutions and excluded patients in the acute stage of disease. The paper reports measurement properties, not whether the scale improves patient education, self-care, or clinical outcomes.
Declared interests
The authors declare no conflicts of interest.
The easy way to misread this
Do not read the validation results as proof that using the scale improves patient education or outcomes. The study tested measurement properties in 391 patients, not clinical benefit.
