Return-to-work self-efficacy questionnaire: Cross-cultural adaptation and validation in China

Abstract

Aim: To develop a Chinese version of the return-to-work self-efficacy (RTW-SE-11) and verify its reliability and validity. Design: A validation study. Methods: The RTW-SE-11 was translated into Chinese according to the Brislin's model, and then the semantic adjustment of questionnaire was carried out through multi-field expert evaluation and preliminary investigation. Results: All 11 items of the original questionnaire were retained. Content validity index (CVI) of the Chinese version of RTW-SE-11 indicated good validity, with Inter-rater Agreement (IR) of 0.97, item CVI of 0.90–1.00 and questionnaire CVI of 0.91. Cronbach's α coefficient of RTW-SE-11 (Chinese version) was 0.923, suggesting high internal consistency, with test–retest reliability of 0.799 and half-fold reliability of 0.926. Patient or public contribution: The Chinese version of the RTW-SE-11 questionnaire confirmed good reliability and validity for the assessment of return to work self-efficacy in Chinese breast cancer patients.
