影像专科护士核心能力评价指标的构建、信效度检验分析

Construction of evaluation index system of core competence of imaging specialized nurses and analysis of reliability and validity test

目的探讨影像专科护士核心能力评价指标的构建、信效度检验分析。方法首先成立研究小组查阅相关文献资料,经过研究小组成员反复讨论并邀请影像专科护士讨论、修改、完善评价指标体系框架,形成影像专科护士核心能力评价指标体系专家咨询问卷。通过两轮专家咨询构建影像专科护士核心能力评价指标体系,并以构建的指标体系为依据编制问卷调查表。采用问卷调查的方法验证本研究所构建的影像专科护士核心能力评价指标体系的合理性和科学性。结果构建的影像专科护士核心能力评价指标体系包括3个一级指标、20个二级指标和48个三级指标。评价指标体系总体Cronbach’sα系数为0.972,一级指标影像专科护理理论知识、影像专科护士护理实践技能、相关能力的Cronbach’sα系数分别为0.915、0.934、0.924。指标体系总体内容效度(content validity index,CVI)指数(S-CVI)为0.977,各条目的内容效度指数(I-CVI)为0.812~1.000。一级指标与指标体系总体相关系数为0.800~0.936(P<0.05),二级指标与相应一级指标相关系数为0.562~0.972(P<0.05),三级指标与相应一级指标的相关系数为0.362~0.914(P<0.05)。结论构建的影像专科护士核心能力评价指标问卷信度良好,内部结构一致,具有较好的可行性、可靠性、合理性和科学性,为影像专科护士核心能力培养考核和评价提供了理论依据和实践指南。

Objective To explore the construction of evaluation index system of core competence of imaging specialized nurses and analysis of reliability and validity test.Methods Firstly,a research group was established to consult the relevant literature.After repeated discussion among the members of the research group,imaging specialized nurses were invited to discuss,modify and improve the framework of the evaluation index system,and an expert consultation questionnaire for the evaluation index system of the core competence of imaging specialized nurses was formulated.Through two rounds of expert consultation,the core competence evaluation index system of imaging specialized nurses was constructed,and a questionnaire was compiled based on the constructed index system.Questionnaire survey method was used to verify the rationality and scientificity of the core competence evaluation index system of imaging specialized nurses constructed in this study.Results The evaluation index system of core competence of imaging specialized nurses included 3 first-level indexes,20 second-level indexes and 48 third-level indexes.The overall Cronbach'sαcoefficient of the evaluation index system was 0.972.The Cronbach'sαcoefficients of the theoretical knowledge of imaging specialized nursing,nursing practice skills of imaging specialized nurses and related abilities were 0.915,0.934 and 0.924 respectively.The overall content validity index(S-CVI)of the index system was 0.977,and the CVI of each item(I-CVI)was 0.812-1.000.The overall correlation coefficient of the first-level indexes and index system was 0.800-0.936(P<0.05),the correlation coefficient of the secondary indexes and the corresponding primary indexes was 0.562-0.972(P<0.05),and the correlation coefficient of the third-level indexes and the corresponding first-level index was 0.362-0.914(P<0.05).Conclusion The constructed questionnaire for evaluation index of core competence of imaging specializied nurses has good reliability and consistent internal structure,and has good feasibility,reliability,rationality and scientificity,which provides a theoretical basis and practical guide for the cultivation,assessment and evaluation of core competence of imaging specialized nurses.
