Development of the Holistic Nursing Competence Scale.

This study developed a scale to measure the nursing competence of Japanese registered nurses and to test its psychometric properties. Following the derivation of scale items and pilot testing, the final version of the scale was administered to 331 nurses to establish its internal consistency, as well as its construct and criterion-related validity. Using an exploratory and a confirmatory factor analysis, 36 items with a five-factor structure were retained to form the Holistic Nursing Competence Scale. These factors illustrate nurses' general aptitude and their competencies in staff education and management, ethical practice, the provision of nursing care, and professional development. The Scale has a positive correlation with the length of clinical experience. A Cronbach's alpha coefficient was 0.967. The Scale is a reliable and valid measure, helping both nurses and organizations to correctly evaluate nurses' competence and identify their needs for professional development.
