PMID 41417377WHAT IT FOUND
After review by 10 expert judges and testing in 225 adults, a COVID-19 vaccination hesitancy questionnaire kept 23 questions across four themes.
It measures hesitancy, not vaccine uptake.
Key findings
01The tested hesitancy section had 29 items, and the final hesitancy section had 23 items.
02The final hesitancy items formed four factors.
03The construct validation sample included 225 adults.

What it does not show
The construct validation data were collected cross-sectionally by self-report, which can introduce information bias. Participants were recruited through snowball sampling from the authors' networks, so the sample may not represent all adults or primary care patients. The paper recommends larger samples to standardise scores, so cut-off scores for hesitancy are not established. The health-condition section was descriptive and was not subjected to construct validation.
Declared interests
The paper lists funding from the University of Pernambuco and CAPES. It does not report additional conflicts of interest.
The easy way to misread this
Do not treat the validated questionnaire as proof that asking these questions will raise vaccination rates. The study measured hesitancy in 225 adults but did not test whether the tool changes care or uptake.
