Objectives: To develop and validate an instrument to assess nursing students' perceived knowledge on the International Classification for Nursing Practice.
Methods: The study design is an initial development of a scale by a longitudinal, prospective, monocentric study. An instrument, including a final pool of 6 items, was developed and through a Content Validity approved by experts. Cronbach's alpha coefficient, Exploratory Factor Analysis and Confirmatory Factor Analysis were calculated in a sample of nursing students.
Results: The instrument demonstrated a CVI of 1.0. Cronbach's alpha coefficient was 0.879. Exploratory Factor Analysis indicated one component, with a saturation of items in the range between 0.594 and 0.856. Confirmatory Factor Analysis confirmed the structure.
Conclusions: Although further studies are needed, the preliminary analyses of the instrument suggest satisfaction in terms of content validity, factorial structure, and reliability. This instrument may rise interest in international nursing educational context.
