摘要/Abstract

摘要： 目的编制医护人员医疗辐射防护知信行量表,并进行信效度检验。方法以知信行理论为基础,采用文献调研、头脑风暴、专题小组讨论及对医疗辐射相关医护人员进行小组访谈的方法拟定量表条目池;通过专家咨询、修订后形成初始量表;运用预调查数据进行条目质量分析形成正式量表,并于2022年8月对长沙市376名医护人员进行问卷调查,检验量表的信效度。结果医护人员医疗辐射防护知信行量表包括27个条目3个维度,累计方差贡献率为76.876%;验证性因子分析显示,模型各项指标达到标准,整体模型拟合效果良好。量表的平均内容效度系数为0.936,知识、态度、行为各维度的平均内容效度系数分别为0.933、0.944和0.931,条目的内容效度系数为0.833~1.000。总量表的Cronbach’s α系数为0.957,重测信度系数为0.835,分半信度系数为0.845;各维度的Cronbach’s ɑ 系数分别为0.970、0.939和0.954。结论本研究形成的医疗辐射防护知信行量表具有良好的信效度,适用于中国医护人员辐射防护知信行水平的测评。

Abstract: Objective To develop a medical radiation protection knowledge-attitude-practice（KAP） scale for medical staff,and to test the reliability and validity of the scale. Methods Based on the theory of KAP,a scale item pool was initially formed by means of literature research,brainstorming,focus group discussion and interviews with medical radiation related personnel. The initial scale was formed through expert consultation and revision. Using pre survey data for item quality analysis to form a formal scale,and 376 medical staff were surveyed in August 2022 to test the reliability and validity of the scale. Results The medical radiation protection KAP scale for medical staff consisted of 27 items with 3 dimensions,with a cumulative variance contribution rate of 76.876%.The confirmatory factor analysis showed that all indicators of the model met the standards,and the overall model fitting effect was good.The average content validity index at the scale level was 0.936,and the average content validity index for knowledge,attitude,and practice dimensions were 0.933,0.944 and 0.931,respectively. The content validity index of the items range from 0.833 to 1.000.The Cronbach's α coefficient of the total scale was 0.957,the test-retest reliability was 0.835,and the split-half reliability was 0.845. The Cronbach's α coefficient for each dimension were 0.970,0.939,and 0.954,respectively. Conclusion The medical radiation protection KAP scale has good reliability and validity,which is suitable for the evaluation of medical radiation protection KAP level for medical staff in China.
