PMID 38896704WHAT IT FOUND
The LYMPH-ICF lymphedema questionnaire now has a Brazilian Portuguese version.
Ten women pretested it, and experts agreed the wording was clear, but its scores still need testing in larger studies.
Key findings
01The LYMPH-ICF was translated and cross-culturally adapted into Brazilian Portuguese through translation, back-translation, expert review, and pretesting.
02The expert committee agreement was 0.90, scores above 0.80 were considered satisfactory, and the final Brazilian version was considered suitable for use in the studied population.
03The pre-test included 10 women with upper limb lymphedema secondary to breast cancer, and at least one patient marked 8 questions as not applicable because of her routine, not because the item was unclear.

What it does not show
The pre-test used only 10 women, so it cannot show how the questionnaire performs in a larger group. All participants came from one centre, so the wording and comprehension may not transfer to other Brazilian regions or services. The sample was fairly homogeneous, with an average age around 55 years and at least primary education. The study reports content agreement and a final version, not reliability or validation in larger studies.
The easy way to misread this
Do not treat the adapted Portuguese LYMPH-ICF as a validated outcome measure or evidence that it improves lymphedema care. The study only translated it, obtained expert agreement, and pretested it in 10 women; reliability and validation remain to be tested.
