OBJECTIVE
design and validate a questionnaire to evaluate the knowledge and attitudes of nurses about the subcutaneous venous reservoir.
METHOD
pilot test: 30 specialized care nurses. Main study: 236 nurses of primary and specialized care. Content validity was evaluated by Lawshe index, reliability by test-retest, internal consistency by Cronbach alpha, and construct validity by exploratory factorial analysis.
RESULTS
Items with a Lawshe index lower than 0.51 were eliminated. In the test-retest, the intraclass correlation coefficient was higher than 0.75 for all items. The Cronbach alpha of the attitude questionnaire reached 0.865. The Cronbach alpha value for knowledge was 0.750. The exploratory factor analysis identified a set of four dimensions for each part that explain 64% (attitude) to 80% (knowledge) of variability.
CONCLUSION
the analysis of the reliability and validity of the questionnaire supports its use as an instrument to assess the knowledge and attitudes of nurses towards the subcutaneous venous reservoir.
目的
设计并验证一份问卷，以评估护士对皮下静脉储器的知识和态度。
方法
预试验：30名专科护理护士。主要研究：236名初级和专科护理护士。通过劳斯指数评估内容效度，通过重测评估信度，通过克朗巴赫α系数评估内部一致性，通过探索性因子分析评估结构效度。
结果
劳斯指数低于0.51的项目被剔除。在重测中，所有项目的组内相关系数均高于0.75。态度问卷的克朗巴赫α系数达到0.865。知识问卷的克朗巴赫α值为0.750。探索性因子分析为每个部分确定了一组四个维度，这些维度解释了64%（态度）至80%（知识）的变异性。
结论
问卷的信度和效度分析支持将其用作评估护士对皮下静脉储器的知识和态度的工具。
