PICC带管患者的主要照顾者PICC护理知信行量表的编制及信效度检验

Development of the PICC Nursing Knowledge,Attitude and Practice Scale for Primary Caregivers of Patients with PICC and its reliability and validity

目的编制经外周静脉置入中心静脉导管(PICC)带管患者的主要照顾者PICC护理知信行评估量表,并进行信效度检验。方法以知信行理论为基本框架,于2021年3—4月通过文献回顾、小组讨论、半结构式访谈初步构建条目池;于2021年5—7月通过德尔菲专家咨询形成初始量表,通过认知性访谈对量表各条目进行预测试和调整;于2021年6—10月采用便利抽样法选取湖南省某肿瘤医院450名PICC带管患者的主要照顾者进行正式调查,检验量表信效度。结果正式量表由3个维度53个条目组成,其中知识维度19个条目、态度维度8个条目、行为维度26个条目。各维度及总量表的Cronbach'sα系数分别为0.949、0.962、0.972、0.981;各维度及总量表的重测信度系数分别为0.951、0.935、0.972、0.967,各维度及总量表的分半信度指数分别为0.889、0.954、0.889、0.882。量表条目内容效度指数为0.82~1.00。结论PICC带管患者的主要照顾者PICC护理知信行量表信效度良好,可作为评价PICC置管患者主要照顾者PICC护理知信行的工具。

Objective To develop the Peripherally Inserted Central Catheter(PICC)Nursing Knowledge,Attitude and Practice Scale for Primary Caregivers of Patients with PICC,and to test its reliability and validity.Methods Taking the theory of knowledge,attitude and practice as the basic framework,the item pool was initially constructed through literature review,group discussion,and semi-structured interviews from March to April 2021.From May to July 2021,the initial scale was formed through Delphi expert consultation,and the items of the scale were pre-tested and adjusted through cognitive interviews.From June to October 2021,convenience sampling was used to select the primary caregivers of 450 patients with PICC in a cancer hospital in Hunan Province for a formal survey to test the reliability and validity of the scale.Results The formal scale consisted of 53 items in 3 dimensions,including 19 items in the knowledge dimension,8 items in the attitude dimension,and 26 items in the practice dimension.The Cronbach'sαcoefficients of each dimension and the total scale were 0.949,0.962,0.972,and 0.981,respectively,and the test-retest reliability coefficients of each dimension and the total scale were 0.951,0.935,0.972,and 0.967,respectively.The split-half reliability coefficients of each dimension and the total scale were 0.889,0.954,0.889,and 0.882,respectively.The content validity index of the item ranged from 0.82 to 1.00.Conclusions The reliability and validity of the PICC Nursing Knowledge,Attitude and Practice Scale for Primary Caregivers of Patients with PICC is good,and it can be used as a tool to evaluate the PICC nursing knowledge,attitude,and practice of primary caregivers of patients with PICC.
