Abstract：
Background and Purpose: To validate the scales of knowledge, attitude, and practice of self-care for arteriovenous fistulas in renal patients on hemodialysis. Methods: A methodological study verified the evidence of validity based on the content, response processes, and internal structure of the scales. The content was evaluated by six judges, and the response processes were verified with six patients. In the evaluation of the internal structure, the scales were applied to 220 patients for exploratory factor analysis with evaluation of McDonald\'s omega adjustment and calculation indexes. Results: The scales explained variance and McDonald\'s omega values of 40.4%/0.896, 60.7%/0.843, and 36.9%/0.702 for the knowledge (19 items), attitude (4 items), and practice (8 items), respectively. Conclusions: The scale of attitude was valid after the analysis of the content evidence, response processes, and internal structure. The arteriovenous fistula self-care knowledge and practice scales explained less than 50% of the constructs. Therefore, it is recommended that new studies be conducted to validate scales of knowledge and practice of fistula self-care.
摘要：
背景和目的：为了验证知识的尺度，态度,肾脏血液透析患者动静脉瘘的自我护理实践。方法：通过方法学研究，根据内容验证了有效性的证据，响应过程，和尺度的内部结构。六位评委对内容进行了评估,对6名患者的反应过程进行了验证。在评价内部结构时,将该量表应用于220例患者进行探索性因素分析，并评估McDonald的omega调整和计算指标。结果：量表解释了知识的方差和McDonald的omega值分别为40.4％/0.896、60.7％/0.843和36.9％/0.702（19项），态度（4项），和实践(8项)，分别。结论：经过对内容证据的分析，态度量表是有效的。响应过程，和内部结构。动静脉瘘自我护理知识和实践量表解释了不到50％的构造。因此,建议进行新的研究以验证瘘管自理知识和实践的量表.
