Translation and cross-cultural adaptation of the therapeutic intervention manual Rapid Syllable Transition Treatment (ReST) into brazilian portuguese.
Beatriz de Oliveira, Aline Mara de Oliveira
PMID 36946860WHAT IT FOUND
The ReST speech motor disorder therapy manual is now available in Brazilian Portuguese after translation, cultural adaptation, and a two-child pilot.
The pilot showed acceptance and progress, but it does not prove the method works.
Key findings
01The ReST manual was translated into Brazilian Portuguese with the original authors' approval, and the adaptation process reached a final audited version.
02The adaptation changed therapy terms and pseudoword examples for Brazilian Portuguese, and the pilot showed that another lexical stress pattern was needed.
03In a two-child pilot, the adapted manual was used in 12 telecare sessions; the children accepted it and showed progress, but effectiveness was not established.

What it does not show
The clinical part was only a two-child pilot, so it cannot show that the adapted manual works for other children. There was no control group, randomisation, or comparison with usual therapy. The pilot used telecare, so the results may not apply to in-person sessions. The participants were selected from one university clinic and had severe speech sound disorders without comorbidities or hearing loss, so the results may not apply to other clinical groups. The authors state that effectiveness will be discussed in future publications and that larger randomised validation is still needed.
The easy way to misread this
Do not read the gains in the two-child pilot as proof that the adapted ReST manual works. The study had only two participants, no comparison group, and the authors say larger randomised validation is still needed.
