Translation and Validation of the Spanish Version of the Competency Inventory of Nursing Students.

Background: Competencies, such as knowledge, critical thinking, and clinical reasoning skills, are the essential individual characteristics required for effectively carrying out nursing duties. The acquisition and assessment of these competencies among nursing students are crucial for their future practice. This study aims to validate the Competency Inventory of Nursing Students in Spanish. Methods: Validation and back-translation into Spanish of the Nursing Competency Inventory of Nursing Students. Results: The sample was collected from the University of Barcelona, Lleida, and Tecnocampus. Most participants (85.3%) were females between 20 and 29, and 45.3% were in their third year. The general answer mean was 6.34 points. Dimension 4 (Clinical biomedical science) obtained the lowest score and dimension 1 (Ethics and accountability) the highest. The content validity index for the entire scale was 0.93. The Kaiser-Meyer-Olkin measure was 0.926. The Spanish version of the scale demonstrated a Cronbach's alpha of 0.95. Conclusions: The Spanish CINS version is a valid and reliable tool that can be used to evaluate nursing students' competencies in the Spanish context.
