A valid and reliable instrument for assessing exercise self-regulatory efficacy (Ex-SRE) is lacking in Taiwan.
To develop and validate a Chinese-version of the Ex-SRE scale (Ex-SRES-Chinese).
Published guidelines were followed for cross-cultural adaptation of Ex-SRES-Chinese. Psychometric testing was conducted in 76 subjects with chronic obstructive pulmonary diseases (COPD).
Ex-SRES-Chinese achieved clarity, culture appropriateness, and functional equivalence for measuring Ex-SRE. The scale-level content validity index of the Ex-SRES-Chinese was 0.99. The internal consistency reliability (Cronbach's α) was 0.925. Factor analysis identified a single factor with a high eigenvalue of 7.6 accounting for 47.5% of the total variance. The construct validity of Ex-SRES-Chinese was supported by higher Ex-SRE in subjects who exercise regularly in the past than those who did not (p = 0.033). In addition, Ex-SRE was positively associated with weekly exercise time (r = 0.58; p < 0.0001).
Ex-SRES-Chinese is a useful cross-culturally adapted instrument with good psychometric properties for measuring Ex-SRE in COPD patients in Taiwan.
台湾缺乏一种有效且可靠的评估运动自我调节效能（Ex-SRE）的工具。
开发并验证中文版运动自我调节效能量表（Ex-SRES-Chinese）。
遵循已发表的指南对Ex-SRES-Chinese进行跨文化调适。对76例慢性阻塞性肺疾病（COPD）患者进行心理测量测试。
Ex-SRES-Chinese在测量Ex-SRE方面实现了清晰度、文化适宜性和功能等效性。Ex-SRES-Chinese的量表水平内容效度指数为0.99。内部一致性信度（Cronbach's α）为0.925。因子分析确定了一个单一因子，其特征值较高，为7.6，占总方差的47.5%。过去经常锻炼的受试者的Ex-SRE高于未经常锻炼的受试者，这支持了Ex-SRES-Chinese的结构效度（p = 0.033）。此外，Ex-SRE与每周运动时间呈正相关（r = 0.58；p < 0.0001）。
Ex-SRES-Chinese是一种经过跨文化调适的有用工具，具有良好的心理测量特性，可用于测量台湾COPD患者的Ex-SRE。
