摘要
目的编制乳腺癌术后患者预防上肢淋巴水肿知信行量表,并验证其信效度。方法以知信行理论为框架,在循证的基础上结合头脑风暴法构建量表初稿,通过德尔菲法函询专家进一步修订。预调查后,采用便利抽样法抽取2021年9月至11月于西安交通大学第一附属医院住院的200例乳腺癌术后患者进行问卷调查,检验量表的信效度。结果乳腺癌术后患者预防上肢淋巴水肿知信行量表包括知识、态度、行为3个维度,共23个条目。两轮专家函询的积极性系数分别为1.00和0.93,权威性系数分别为0.90和0.89,协调系数分别为0.387和0.287。预调查回收有效问卷30份,有效回收率为100%。根据患者的反馈对回收的量表再次修订,共修改4个条目。正式调查最终回收有效量表162份,有效回收率为81%。总量表与各条目之间的相关系数为0.414~0.787,总量表的内容效度为0.938,各条目水平的内容效度指数为0.857~1.000,量表的Cronbach’sα系数为0.931,折半系数为0.875,重测系数为0.916。使用探索性因子分析法提取3个公因子,可解释总变量的62.843%,同时验证性因子分析表明模型拟合度良好。结论乳腺癌术后患者预防上肢淋巴水肿知信行量表信效度良好,可以作为患者对淋巴水肿预防知识、态度、行为的评估工具。
Objective To develop a scale of knowledge-attitude-practice of preventing the upper limb lymphedema for breast cancer patients after surgery and test its reliability and validity.Methods Based on the knowledge-attitude-practice theory,the first draft of the scale was constructed on the basis of evidence and combined with brainstorming method.The Delphi method was used to consult experts for further revision.After the pre-survey,a total of 200 breast cancer patients who were hospitalized in the First Affiliated Hospital of Xi’an Jiaotong University from September to November 2021 were selected by convenience sampling for questionnaire survey to test the reliability and validity of the scale.Results The knowledge-attitude-practice scale for preventing upper limb lymphedema in patients after breast cancer surgery includes three dimensions,knowledge-attitude-practice,with a total of 23 items.The positive coefficients of the two rounds of expert consultation were 1.00 and 0.93,the authoritative coefficients were 0.90 and 0.89,and the coordination coefficients were 0.387 and 0.287.Thirty valid questionnaires were collected in the pre-survey with an effective recovery rate of 100%.The recovered scale was revised again according to the patient’s feedback,and a total of four items were modified.A total of 162 valid questionnaires were recovered from the formal investigation,with an effective recovery rate of 81%.The correlation coefficient between the total scale and each item was 0.414-0.787,the content validity of the total scale was 0.938,the content validity index of each item level was 0.857-1.000,the Cronbach’sαcoefficient of the scale was 0.931,the split half coefficient was 0.875,and the test-retest coefficient was 0.916.Exploratory factor analysis was used to extract three common factors,which could explain 62.843%of the total variables,and confirmatory factor analysis showed that the model had a good fit.Conclusion The knowledge-attitude-practice scale for preventing upper limb lymphedema in patients after breast cancer surgery has good reliability and validity,and can be used as an assessment tool for patients’knowledge-attitude-practice of lymphedema prevention.
