循证实践实施氛围量表的汉化及信效度检验

Translation and validation of the Implementation Climate Scale

目的 引进、汉化循证实践实施氛围量表,并检验中文版量表的信效度,为我国护理人员循证实践实施氛围感知的评估提供测量工具。方法 采用Brislin翻译模型,通过翻译、回译和文化调适,形成中文版循证实践实施氛围量表。采用方便抽样法抽取1所三甲医院的297名护士进行调查,评价量表信效度。结果 中文版量表包括对循证实践的关注、对循证实践的教育支持、对循证实践的认可、对循证实践的奖励、循证实践的人员选拔以及选拔人员的开放性6个维度共18个条目。量表18个条目的决断值(CR)为19.884~32.438,各条目与总分的相关系数(r)为0.776~0.883(均P<0.01)。平均内容效度指数(S-CVI/Ave)为0.926。验证性因子分析结果显示,模型各项指标均达到标准,模型拟合较好。总量表Cronbach′sα系数为0.975,重测信度为0.983,折半信度为0.935。结论 中文版循证实践实施氛围量表在国内护士群体中具有较好的信效度,可以用于测评护士对循证实践实施氛围的感知。

Objective To translate the Implementation Climate Scale(ICS),and to test its reliability and validity,so as to provide a measurement tool assessing perceived implementation climate of evidenced based practice in Chinese nurses.Methods A Chinese version of the ICS was developed using the Brislin translation model through translation,back translation and cultural adaptation.Then it was used to investigate 297 nurses from a tertiary hospital using convenience sampling to test its reliability and validity.Results The Chinese version ICS included six dimensions of focus on evidence-based practice,educational support for evidence-based practice,recognition for evidence-based practice,rewards for evidence-based practice,selection of practitioner for evidence-based practice,and selection for openness,with a total of 18 items.The decision values(CR) for the 18 items ranged from 19.884 to 32.438,and the correlation coefficients(r) between each item and the total scale score ranged from 0.776 to 0.883(P<0.01 for all).The S-CVI/Ave was 0.926.The confirmatory factor analysis showed that,all indicators of the model met the criteria and the model fitted well.The Cronbach′s alpha coefficient of the scale was 0.975,its test-retest reliability was 0.983,and the split-half reliability was 0.935.Conclusion The Chinese version ICS has good reliability and validity in domestic nurses,and it can be used to measure nurses′ perception of the climate for implementing evidence-based practice.
