PMID 38126594WHAT IT FOUND
The Dysphonia Screening Tool was adapted into European Portuguese using two simple yes/no questions about voice strain and hoarseness.
Thirty people with dysphonia understood the items without needing a 'not applicable' option. This version requires formal validation before clinical use.
Key findings
01The adapted European Portuguese version consists of two items: 'I feel that I strain to produce my voice' and 'My voice is hoarse'.
02In a pre-test with 30 participants, no one selected the 'not applicable' option for either item, indicating the questions were understood by the target population.
03This cross-cultural adaptation is a preliminary step; the tool has not yet been validated for accuracy or reliability in European Portuguese.

What it does not show
The study only reports the adaptation process and a small comprehension check, not the accuracy of the tool. The pre-test sample was small (n=30) and consisted entirely of people who already had a dysphonia diagnosis, so it does not show how the tool performs in the general population. Validation studies for reliability and accuracy are explicitly stated as necessary next steps and have not been performed.
The easy way to misread this
Do not treat this adapted tool as a validated screening instrument. The paper describes the translation and a basic comprehension check, but explicitly states that validation studies to prove its accuracy and reliability are still needed.
