AIM
The aim of the study is to develop a scale to measure nurses' self-efficacy levels regarding safe blood transfusion practice.
METHODS
This study, applied in methodological design, was conducted in a public university hospital in Istanbul between March-April 2021. The sample included 372 nurses. A draft form consisting of 75 items was prepared. Content validity, construct validity, distinctiveness, internal consistency reliability, two-half test reliability, test-retest, and item analysis methods were used to determine the psychometric properties of the scale.
RESULTS
The exploratory factor analysis showed that the scale had a four-factor structure that explained 71.36 % of the total variance. The factor loads of 49 items were found to vary between 0.50 and 0.92. The item-total correlations were found to be between 0.55 and 0.92. The Cronbach's alpha value for the whole scale was 0.96.
CONCLUSION
The results of the analysis show the items constituting Safe Blood and Blood Products Transfusion Self-Efficacy Scale have validity and reliability criteria that can measure the nurses' self-efficacy levels regarding safe blood transfusion practice.
目的
本研究旨在开发一种衡量护士在安全输血实践方面自我效能感的量表。
方法
本研究采用方法学设计，于 2021 年 3 月至 4 月在伊斯坦布尔的一所公立大学医院进行。样本包括 372 名护士。编制了一份包含 75 个项目的草案。采用内容效度、结构效度、区分度、内部一致性信度、两半测试信度、重测信度和项目分析方法来确定量表的心理测量特性。
结果
探索性因子分析显示，该量表具有四因素结构，可解释总方差的 71.36%。49 个项目的因子负荷在 0.50 到 0.92 之间。项目-总分相关系数在 0.55 到 0.92 之间。整个量表的克朗巴赫α值为 0.96。
结论
分析结果表明，构成安全输血和血液制品输血自我效能感量表的项目具有可衡量护士在安全输血实践方面自我效能感的有效性和可靠性标准。
