Psychometric properties evaluation of the Advance Care Planning Readiness Scale for community-dwelling older adults with chronic diseases residing in suburban counties within the Chinese context.

The sample was recruited by convenience and came only from four suburban counties in Chengdu, China, so it may not apply to other older adults or settings. Only adults with a cognitive screen score above 20 and a primary education level were included, so it may not apply to people with more severe cognitive impairment or different educational backgrounds. The study did not test whether responses are stable over time or match an external standard, because repeated questions about death were considered sensitive. The scale is self-report, so responses may be biased by what participants chose to say. No patient outcomes were measured, so the study cannot show that using the scale improves care.

The authors declared no conflicts of interest. The work was supported by the Sichuan Provincial Cadre Healthcare Research Program.

Do not conclude that using this scale improves patient care or outcomes. The study tested only how well the questionnaire measured readiness in suburban Chinese older adults with chronic disease, and it did not test stability over time or agreement with an external standard.
