Website for families of non-breastfed children: development and validation of content and interface.
Marília Alessandra Bick, Cristiane Cardoso de Paula
PMID 38896662WHAT IT FOUND
A new website guiding families on formula and milk feeding for infants under six months was rated highly by experts for accuracy and usability.
It is not yet tested on real patients, so its effect on feeding safety or health outcomes remains unknown.
Key findings
01The website achieved an overall Content Validity Index of 0.91, exceeding the acceptable threshold of 0.80.
02Experts identified that the text contained technical terms that might not be suitable for the target audience.
03The study did not involve families in the final validation stage due to pandemic isolation, so patient usability is unconfirmed.

What it does not show
The target population (families) did not participate in the final validation due to pandemic restrictions. The sample consisted of experts, not patients, so real-world usability and comprehension by caregivers are unproven. The study measured expert agreement, not clinical outcomes like infant growth or infection rates.
Declared interests
The study was part of a matrix project supported by the Brazilian National Council for Scientific and Technological Development (CNPq) and the Coordination for the Improvement of Higher Education Personnel (CAPES). The authors declared no conflicts of interest.
The easy way to misread this
Do not assume this website improves infant health outcomes or caregiver confidence. It has only been validated by experts for content accuracy and interface design; it has not yet been tested in practice with families.
