Abstract:
Objective:To develop an Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses and test its reliability and validity.Methods:Based on the theory of knowledge, attitude, and practice, a preliminary scale draft was formed through a literature review, three rounds of Delphi expert consultation, and a pre-survey. Using convenience sampling, 311 hemodialysis nurses were selected for a survey from December 2022 to February 2023 for item analysis, exploratory factor analysis and reliability testing. Another survey was conducted on 260 hemodialysis nurses from February to June 2023 for confirmatory factor analysis, convergent validity, and discriminant validity testing.Results:The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses included three subscales and five dimensions, with a total of 33 items. The content validity index at the item level was 0.867 to 1.000, and the content validity index at the scale level was 0.992. After exploratory factor analysis, two, one, and two common factors were extracted from the knowledge, attitude, and practice subscales, with cumulative variance contribution rates of 70.114%, 75.192%, and 67.467%, respectively.Confirmatory:factor analysis showed that the model fitted well. The Cronbach's α coefficients of the three subscales were 0.929 to 0.943, the half reliability coefficients were 0.861 to 0.903, and the retest reliability coefficients were 0.824 to 0.874. Conclusions The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses has good reliability and validity and can be used to evaluate the physical examination ability of hemodialysis nurses for arteriovenous fistula.
