AACN健康工作环境评估量表的汉化及信度效度检验

Reliability and validity of the Chinese version of AACN Healthy Work Environment Assessment Tool

目的 :汉化美国重症护理协会(AACN)健康工作环境评估量表并在ICU护士中进行信度、效度检验。方法 :采用Brislin双向翻译模型对量表进行汉化,经专家委员会进行文化调试及预实验后形成中文版量表。抽取杭州市6家三级甲等医院425名ICU护士进行调查,以检验中文版量表的信度、效度。结果 :中文版AACN健康工作环境评估量表包括6个维度,共18个条目,累计方差贡献率为75.884%。总量表的Cronbach’sα系数为0.908,各维度的Cronbach’sα系数为0.734～0.871,重测信度为0.870。中文版量表各维度与总量表的相关系数为0.572～0.817(P<0.01)。条目水平的内容效度指数(I-CVI)的范围为0.830～1.000,量表水平的内容效度指数(S-CVI/Ave)为0.991。结论 :中文版AACN健康工作环境评估量表具有较好的信度、效度,适用于ICU护理健康工作环境的测评。

Objective: To translate the AACN Healthy Work Environment Assessment Tool into Chinese, and test the reliability and validity of the Chinese version. Methods: The English version of the tool was translated and back-translated according to Brislin translation model. After modifying the tool according to Chinese culture, the reliability and validity of the Chinese version of the tool was tested among a sample of 425 ICU nurses in Hangzhou. Results: The Chinese version of the tool included 6 dimensions and 18 items. 6 factors were extracted by principal component analysis, which could explain 75.884% of the total variance. The Cronbach’s α for the tool was 0.908, and the Cronbach’s α for six dimensions was among the range from 0.734 to 0.871.The test-retest reliability was 0.870. The correlation coefficient between each dimension and the tool ranged from 0.572 to 0.817(P<0.01). The range of item-level content validity index(I-CVI) was from 0.830 to 1.000. The average of scale-level content validity index(S-CVI/Ave) was 0.991. Conclusion: The Chinese version of the tool is reliable and valid, and is an effective tool to assess the nursing healthy work environment of ICU.
