Validation of the Dutch Translation of the Prosthesis Evaluation Questionnaire

The study consists of two phases. The first phase is the translation of the Prosthesis Evaluation Questionnaire (PEQ) and the second phase is the validation of this questionnaire.

Phase 1 translation PEQ: The Beaton guidelines were followed for the translation of the questionnaire. After translation and back-translation, version A of the translated PEQ was created. This version was tested on 30 adult patients with a lower leg prosthesis. Based on the feedback from the patients, the Dutch language version of the PEQ was created (PEQ-DLV).

Phase 2 validation PEQ-DLV: For the process of validation three questionnaires were used: a general survey, the PEQ-DLV and the RAND-36. The participants were approached via a large orthopedic workshop and the national patient association KorterMaarKrachtig (KMK). The aim was to include 84 lower limb prosthesis users with an unilateral amputation at ankle level or higher. At baseline (T0) patients received a digital consent form, the general survey, the PEQ-DLV and the RAND-36. Two weeks (T1) and three months (T2) after baseline, the participants who completed all questionnaires, received the PEQ-DLV again. For motivation and as a token of appreciation, participants received a compensation of 20 euros after filling in all questionnaires.During the analysis the internal consistency, floor-ceiling effects, test-retest riliability, responsiveness and contruct validity are calculated and determined.
