摘　　要：目的:编制血液透析病人血磷控制知信行问卷,并进行信效度检验。方法:依据知信行理论,通过文献分析及5名专家焦点访谈,初步拟定问卷条目池;应用德尔菲法对15名专家进行2轮函询,根据专家意见调整问卷内容形成初稿。采用量表初稿对某医院298例血液透析病人进行调查,进行项目分析、信度检验和探索性因子分析;间隔1周对20例病人进行重测,检验问卷的重测信度。结果:2轮函询问卷回收率均为100%,专家权威程度为0.960。2轮肯德尔协调系数分别为0.132,0.112(均P<0.05)。正式版血液透析病人血磷控制知信行问卷包括知识、态度、行为3个维度,共37个条目。问卷总体内容效度为0.99,Cronbach′sα系数为0.943,重测信度为0.959。探索性因子分析共产生6个因子,其中知识维度2个因子,态度维度1个因子,行为维度3个因子,累计方差贡献率为68.276%,每个条目在各因子上的载荷均>0.4。结论:编制的血液透析病人血磷控制知信行问卷具有良好的信效度,适用于血液透析病人血磷控制知信行的评估。Objective:To develop a questionnaire on the knowledge-attitude-practice(KAP)of blood phosphorus control in hemodialysis patients and to test its reliability and validity.Methods:According to the theory of KAP,the item pool was preliminarily developed through literature review and interviews with 5 experts.Delphi method was applied to consult 15 experts,and the first draft was formed according to the opinions of experts.A preliminary scale was used to investigate 298 hemodialysis patients in three centers of one hospital,and item analysis,reliability test and exploratory factor analysis were carried out.20 patients were retested after 1 week interval.Results:The answer rates of the two rounds consultation were 100%,and the expert authority was 0.960.The Kendall coordination coefficient of the two rounds were 0.132,0.112(all P<0.05).The formal KAP questionnaire of blood phosphorus control included 37 items in knowledge,attitude,behavior 3 dimensions.The overall content validity was 0.99,Cronbach'sαcoefficient was 0.943,the retest reliability was 0.959.Exploratory factor analysis produced 6 factors,2 factors in the knowledge dimension,1 factor in the attitude dimension,and 3 factors in the behavior dimension.The cumulative variance contribution rate was 68.276%,and the load of each item on each factor was>0.4.Conclusion:The questionnaire has good reliability and validity,and can be used to evaluate the KAP of blood phosphorus control in hemodialysis patients.
