Purpose: Blood transfusion is a critical clinical intervention for replacing deficient blood or blood components in patients with acute or chronic conditions. Ensuring transfusion safety is essential to minimize complications and optimize patient outcomes. This study aimed to develop a psychometrically validated scale to evaluate nurses' knowledge and attitudes regarding the safety of blood and blood product transfusions. Material and Methods: This methodological study was conducted with 684 nurses, of whom 374 comprised the EFA sample and 310 comprised the CFA sample. The scale's validity and reliability were assessed using Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), item analysis, Cronbach's alpha coefficient, and test-retest reliability evaluation. Results: EFA, performed with 374 participants, identified a four-factor structure explaining 65.88% of the total variance. The Kaiser-Meyer-Olkin (KMO) value was 0.836, indicating sampling adequacy. CFA with 310 participants confirmed this four-factor model. The 15-item model demonstrated good fit indices: chi²/df = 1.453 (<3), GFI = 0.953 (>0.90) , IFI = 0.977 (>0.95), TLI = 0.970 (>0.95), CFI = 0.976 (>0.97), and RMSEA = 0.038 (<0.05). All standardized factor loadings exceeded 0.50, supporting construct validity. Internal consistency was acceptable, with a Cronbach's alpha of 0.786. Conclusion: "The Blood and Blood Products Transfusion Safety Knowledge and Attitude Scale," with its strong psychometric properties, is a reliable assessment tool for both research and clinical practice, and can be effectively used in nursing education and quality improvement initiatives.
