Objective To develop and evaluate an acceptance scale for arteriovenous fistula (AVF) ultrasound technology in hemodialysis nurses. Methods Based on the technology acceptance model, the primary pool of items for the scale was initially developed through conceptual analysis, literature review, and semi-structural interviews. The primary version of the evaluation scale for acceptance of AVF ultrasound technology in hemodialysis nurses was then formed through the Delphi method of expert consultation. The reliability and validity of the scale were evaluated through a survey of hemodialysis nurses. Results A total of 440 questionnaires were distributed in this study, and 430 valid questionnaires were retrieved, with a valid recovery rate of 97.73%. The scale encompasses 5 dimensions (38 items), namely perceived usefulness, perceived ease of use, external factors, user attitudes, and behavioral intentions. The Cronbach's α coefficient of the total scale is 0.934, and the test-retest reliability is 0.875. The scale-level content validity index (Scale-Content Validity Index, S-CVI) is 0.978, and the item-level content validity index (Item-Content Validity Index, I-CVI) ranges 0.800 to 1.000. Conclusion The acceptance assessment scale for AVF ultrasound technology in hemodialysis nurses has a better reliability and validity, and can be used as a tool to measure the willingness and difficulties to widely use AVF ultrasound technology in hemodialysis nurses.
