BACKGROUND AND PURPOSE:

Thirst-related distress in individuals with heart failure (HF) is associated with exacerbated symptoms. This study aimed to culturally adapt the Thirst Distress Scale for Patients with Heart Failure (TDS-HF) for Brazil and assess the content validity of the adapted version.

METHODS:

The TDS-HF was translated, back-translated, and evaluated for linguistic equivalence, clarity, relevance, and pertinence by seven professional experts. The adapted TDS-HF was administered to 40 patients with HF, who provided feedback on its understandability.

RESULTS:

The adaptation achieved satisfactory evidence of linguistic equivalence and content validity, with a total content validity coefficient of 0.95. The patients understood the translated version effectively.

CONCLUSION:

The Brazilian TDS-HF maintains linguistic equivalence to the original version and demonstrates satisfactory evidence of content validity. Further psychometric testing is deemed necessary for implementation.
