Cultural adaptation of rhytidectomy outcome evaluation questionnaire: facial outcome evaluation

ABSTRACT

Introduction:

Quality of life questionnaires have been shown to be useful to confer greater objectivity to the evaluation of treatment outcomes. In turn, the internationalization of these instruments allows the comparison of different populations, although it requires a specific methodology to avoid misinterpretations due to translation errors or cultural differences. The Facial Outcome Evaluation (FOE) questionnaire, translated to English, is an instrument that is easy to apply and is based on objective questions; therefore, it is highly relevant for this purpose. The questionnaire has already been tested in relation to its reliability, validity, and responsiveness.

Objectives:

To translate and culturally adapt to the Brazilian Portuguese version of the FOE questionnaire.

Methods:

The questionnaire was translated and culturally adapted to Portuguese, according to the methodology proposed by Beaton et al., based on the following 5 phases: phase 1, translation by two native Portuguese speakers; phase 2, generation of a synthetic version; phase 3, reverse translation by two native English speakers; phase 4, review by an evaluation committee; and phase 5, application to a population of 20 people.

Results:

The questionnaire was translated and successfully adapted, without comprehension problems in the final population.
