PMID 40025337WHAT IT FOUND
The Chinese swallowing handicap questionnaire produced consistent scores and was rated relevant by experts, so it can help SLPs capture older adults' own physical, functional, and emotional problems with eating and drinking.
Key findings
01The Chinese DHI had Cronbach's alpha 0.97 for the total scale and 0.89 to 0.94 for the three subscales.
02In 50 older adults retested 3 weeks later, the intraclass correlation was 0.87.
03The 25 items grouped into three factors, and expert content validity was 0.93.

What it does not show
The sample came from five nursing homes in one city in China, so it may not represent older adults with OD in other regions or care settings. Participants were selected by convenience sampling, not random sampling, so the group may not reflect all older adults with OD. The paper reports 550 analysed questionnaires but also reports 50 blank questionnaires excluded, which makes the final count unclear. The study tested scale properties, not whether DHI scores predict aspiration, pneumonia, malnutrition, treatment response, or long-term outcomes. The expert panel had only five nurses, doctors, or therapists, so content validity rests on a small panel.
The easy way to misread this
Do not treat the Chinese DHI as a diagnostic test or as proof that it improves outcomes. It was checked for consistency, expert relevance, and factor structure in a convenience sample of nursing-home residents, and the paper did not test clinical outcomes.
