Abstract

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.

为护士编制安全输血自我效能量表：有效性和可靠性研究

本研究旨在开发一种量表，用于测量护士在安全输血实践方面的自我效能水平。样本包括 372 名护士。编写了一份由 75 个项目组成的表格草案。采用内容效度、建构效度、显著性、内部一致性信度、两次半测试信度、重测和项目分析等方法确定量表的心理测量属性。结果探索性因子分析显示，量表具有四因子结构，解释了总方差的 71.36%。49 个项目的因子载荷介于 0.50 和 0.92 之间。项目-总相关系数介于 0.55 和 0.92 之间。整个量表的 Cronbach's alpha 值为 0.96。结论分析结果表明，构成安全输血和输血产品自我效能感量表的项目具有有效性和可靠性标准，可以测量护士在安全输血实践方面的自我效能感水平。

期刊介绍： Transfusion and Apheresis Science brings comprehensive and up-to-date information to physicians and health care professionals involved in the rapidly changing fields of transfusion medicine, hemostasis and apheresis. The journal presents original articles relating to scientific and clinical studies in the areas of immunohematology, transfusion practice, bleeding and thrombotic disorders and both therapeutic and donor apheresis including hematopoietic stem cells. Topics covered include the collection and processing of blood, compatibility testing and guidelines for the use of blood products, as well as screening for and transmission of blood-borne diseases. All areas of apheresis - therapeutic and collection - are also addressed. We would like to specifically encourage allied health professionals in this area to submit manuscripts that relate to improved patient and donor care, technical aspects and educational issues. Transfusion and Apheresis Science features a "Theme" section which includes, in each issue, a group of papers designed to review a specific topic of current importance in transfusion and hemostasis for the discussion of topical issues specific to apheresis and focuses on the operators'' viewpoint. Another section is "What''s Happening" which provides informal reporting of activities in the field. In addition, brief case reports and Letters to the Editor, as well as reviews of meetings and events of general interest, and a listing of recent patents make the journal a complete source of information for practitioners of transfusion, hemostasis and apheresis science. Immediate dissemination of important information is ensured by the commitment of Transfusion and Apheresis Science to rapid publication of both symposia and submitted papers.
