TL;DR
This paper translates and adapts a cancer dyspnea scale into Brazilian Portuguese to ensure it is culturally appropriate and easy to use.
Contribution
The paper presents a validated Brazilian Portuguese version of the Cancer Dyspnoea Scale (CDS-Br) through a rigorous cross-cultural adaptation process.
Findings
The translated CDS-Br was found to be easy to apply and understand for cancer patients.
Adjustments were made to response keys based on expert feedback and pre-testing with patients.
No further adaptations were needed after testing with five additional participants.
Abstract
To translate and cross-culturally adapt The Cancer Dyspnoea Scale - CDS into Brazilian Portuguese. The original instrument in English was translated by a Brazilian Speech-Language Pathologist (SLP) and a Brazilian translator, both bilingual.

It was pre-tested by applying the translated scale (with the additional option of responding “not applicable”) to 40 cancer patients with dyspnea complaints – 35 initial participants and another five to confirm subsequent adjustments. None of the 35 initial study participants marked “not applicable” in the 12 scale items, but some…
