Abstract

Background: Regular exercise improves psychological and physiological functioning in patients with COPD; and exercise self-regulatory efficacy (Ex-SRE) has been shown to be important for adherence to regular exercise. However, a valid and reliable instrument to measure exercise self-regulatory efficacy in Chinese patients with COPD is lacking.

Purpose: The purpose of this study is to determine semantic equivalenceand preliminary test the psychometric properties of a Chinese version of Self-Regulatory Efficacy Scale(Ex-SRES-Chinese).

Methods: The Ex-SRES-Chinese was established through Beaton et al.'s recommended guidelines. The reliability and validity of the determined Ex-SRES-Chinese was tested on a group of patients with COPD (n = 76) in Taiwan.

Results: The rigorous translation and appraisal process were repeated to translate and culturally adapt Ex-SRES into Chinese, until semantic equivalence of each question between English and Chinese was agreedand accepted by an advisory committee. The overall content validity index of determined Ex-SRES-Chinese was 0.875. The Ex-SRES-Chinese demonstrated excellent internal reliability (Cronbach's alpha 0.92) and construct validity (correlation with weekly exercise time [r = 0.67; P <0.0001] and past exercise experience [r = 0.29; P < 0.01]). After control the age and disease severity, Ex-SRES-Chinese was positively associated with exercise tolerance (six-minute walk distance, 6MWD) (r = 0.26; P < 0.05).

Conclusion: The Ex-SRES-Chinese demonstrated excellent semantic equivalency and initial psychometric properties, and is a short, easily administrated exercise self-regulatory efficacy measure.
