Cross-cultural adaptation of the Self-Efficacy for Home Exercise Programs Scale into Japanese

Abstract

The purpose of this study was to adapt the Self-Efficacy for Home Exercise Programs Scale (SEHEPS) for use in Japan. SEHEPS examines the degree of confidence in performing home exercises. The adaptation involved five steps (forward translation, creation of a forward-translated integrated version of the assessment, backward translation, creation of a provisional Japanese version, and pilot testing) and followed an international guideline for the cross-cultural adaptation of patient-reported outcome measures. The provisional Japanese version was pilot-tested by 16 men and 14 women, aged 52.6 ± 17.1 years, with musculoskeletal disorders who were prescribed a home exercise program. The participants rated their comprehension of the provisional Japanese version of SEHEPS using a 5-point scale (from 1: I don't understand the meaning at all, to 5: I can sufficiently understand the sentence). In the case of scores of 1-3, feedback concerning the difficulty of the expressions was obtained. The percentage of those who selected a score of 4 or higher ranged from 66.7% to 100%, and none of the participants selected a score of 1. Furthermore, based on the comments from the pilot test, the final Japanese version of the SEHEPS was developed through discussion among all five members of the team of translators and authors.
