Özet

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.
