围手术期高血糖患者血糖管理知识问卷编制及信效度检验的研究

Development and validity test of blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia LI

目的 编制围手术期高血糖患者血糖管理知识问卷并检验其信效度.方法 通过文献回顾、专家咨询、2 轮德尔菲专家函询及预调查形成初始问卷.采用便利抽样法,选取2019 年8~9 月于西安交通大学第一附属医院外科病区住院的125 例围手术期高血糖患者为调查对象,对问卷进行条目筛选及信效度检验.结果 本研究共发放问卷 125 份,回收有效问卷 115 份,有效回收率为92.0%.围手术期高血糖患者血糖管理知识问卷包括血糖异常影响因素及危害、手术前后护理观察要点、围手术期血糖控制目标、围手术期血糖管理要点以及围手术期危急状况紧急处理的5个维度,共17个条目.2 轮函询的有效回收率均为 100.00%,专家权威程度为 0.880,变异系数均数为 0.086、0.065(P<0.01).探索性因子分析共提取 5 个公因子,累计方差贡献率为 79.895%.本问卷的Cronbach's α系数为0.905,重测信度为0.955,内容效度指数为0.968.结论 围手术期高血糖患者血糖管理知识问卷具有良好的科学性及实用性,可作为评估围手术期高血糖患者血糖管理知识水平的有效工具.

Objective To develop a blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia and test its reliability and validity.Methods The initial questionnaire was formed through literature review,expert consultation,two rounds of Delphi letter consultation,and pre‑survey.From August to September 2019,a total of 125 perioperative patients with hyperglycemia who were hospitalized in the surgical ward of the First Affiliated Hospital of Xi’an Jiaotong University were selected as the survey objects by the convenient sampling method.The items of the questionnaire were screened and the reliability and validity were tested.Results A total of 125 questionnaires were distributed and 115 valid questionnaires were returned,with an effective recovery rate of 92.0%.The blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia included five dimensions(17 items in total),including influencing factors and hazards of abnormal blood glucose,key points of preoperative and postoperative nursing observation,perioperative blood glucose control goals,perioperative blood glucose management points,and emergency treatment of perioperative critical conditions.The effective recovery rates for both rounds of inquiry are 100.00%,the expert authority coefficient was 0.880 and the average coefficient of variation was 0.086 and 0.065(P<0.01).Exploratory factor analysis extracted a total of five common factors,and the cumulative variance contribution rate was 79.895%.The Cronbach’sαcoefficient of the questionnaire was 0.905,the test‑retest reliability was 0. 955,and the content validity index was 0. 968. Conclusions The blood glucosemanagement knowledge questionnaire for perioperative patients with hyperglycemia is scientific and practical,which can be used as an effective tool to evaluate the blood glucose management knowledge level duringperioperative period.
