The Verbal and Social Interaction Nursing Students questionnaire (VSI-NS) has been created to measure the development ofverbal, social and interactional skills of nursing students with patients, from their perspective in nursing care. The aim of thepresent study was to determine the construct validity and internal consistency reliability of the questionnaire. The study had amethodological and developmental design and was carried out in four steps: adjustment of the items, face validity, data collectionand data analysis. The number of items was reduced from 48 to 31. The factor analysis of the final 31 items resulted in four quitedistinct factors: “Inviting to talk about feelings and thoughts”, “Building a caring relationship”, “Encouraging social and practicalaspects in daily life” and “Caring towards health and wellbeing”. The results showed satisfactory psychometric properties interms of content validity, construct validity and the internal consistency reliability of the questionnaire. It could be concluded thatthe original conceptual model could serve as a theoretical foundation to explain and understand nurses’ caring interactions withtheir patients
