Spanish translation and cross-cultural adaptation of a new severity scale to measure activity in patients with chronic prurigo: Prurigo Control Test (PCT).

OBJECTIVE

Perform the translation and cross-cultural adaptation of the severity scale to measure activity in patients with chronic prurigo: Prurigo Control Test (PCT) for the locality of Río de la Plata, Argentina.

METHODS

A cross-sectional study using a mixed-methods (qualitative and quantitative) approach was performed. The process involved seven stages: translation, expert reconciliation, back-translation into English, equivalence review, expert evaluation, cognitive interviews with patients, and development of the final version.

RESULTS

A Spanish version of the questionnaire was obtained. Eleven patients were interviewed. The median age was 70 years (IQR 59-75), and the median disease duration was 24 months. Correct comprehension of all items was achieved by 90% of the patients. The only modification made was the addition of the clarification "(de la piel)" [of the skin] following the term "cutánea" [cutaneous] to ensure comprehension across all educational levels.

CONCLUSIONS

The translated and adapted version of the PCT constitutes a simple, objective, and valuable tool for assessing disease control and therapeutic response in the daily clinical care of Spanish-speaking patients.
