The heightened focus on patient safety and the quality of nursing care in intensive care units underscores the necessity for reliable tools to evaluate nurses’ ethical awareness. This study was aimed to evaluate the psychometric properties of the Turkish version of the Ethical Awareness Scale in a sample of intensive care nurses. Data were collected from 249 intensive care nurses in Türkiye using the Turkish version of the 18-item Ethical Awareness Scale. The data were then analyzed using Rasch analysis. The Turkish version of the Ethical Awareness Scale demonstrated unidimensionality and an acceptable fit for the Rasch model. The person reliability and item reliability were 0.63 and 0.92, respectively. The Turkish version of the Ethical Awareness Scale was found to be a psychometrically valid and reliable instrument for measuring the ethical awareness levels of intensive care nurses.
