中文版孕妇运动自我效能量表的信效度研究

Reliability and validity of the Chinese version of the Pregnancy Exercise Self-Efficacy Scale

目的探讨孕妇运动自我效能量表(The Pregnancy Exercise Self-efficacy Scale,P-ESES)在孕妇中应用的信度及效度。方法对P-ESES进行翻译、回译和跨文化调试,形成中文版P-ESES;方便抽取在广州市某综合性三级甲等医院产科门诊常规产检的孕妇274例,使用中文版P-ESES对孕妇进行调查,评价量表的信度和效度。结果中文版P-ESES内容信度指数为0.98;共提取3个公因子,累积方差贡献率为60.649%,每个条目在其公因子上的载荷值均大于0.4;重测信度为0.531,总量表的Cronbach'sα系数为0.804。结论中文版P-ESES条目较少,具有良好的信效度,可作为孕妇运动自我效能的测量工具。

Objective To test the reliability and validity of the Chinese version of the Pregnancy Exercise Self-Efficacy Seale（P-ESES） among Chinese population. Methods The Chinese version of P-ESES was translated from the original one,back-translated and adjusted for cultural adaptation. The reliability and validity were tested among 274 eligible pregnant women recruited in one obstetric outpatient clinic from a tertiary hospital in Guangzhou using convenience sampling. Results The content validity index （CVI） of the Chinese version of P-ESES was 0.98. Factor analysis extracted three common factors ,which explained 60.649% of the total variance ,and each item had high factor loading quantity（〉0.4）. The test-retest reliability was 0.531 ,and Cronbach＇s α coefficient was 0.804. Conclusion The Chinese version of the P-ESES has been proved to be reliable and valid. It is a valuable tool for evaluating exercise self-efficacy among pregnant women in China's Mainland.
