Psychometric evaluation of Nurse Professional Competence Scale—Short-form Chinese language version among nursing graduate students

Abstract

Aim: The aim of the study was to determine the psychometric properties, construct validity and internal consistency of the Chinese language version of the Nurse Professional Competence scale short form. Design: A methodological design was used. Methods: Questionnaire data from 260 nursing students nearing graduation from 2 universities in China were analysed using confirmatory factor analysis, known-group validity and internal consistency. Results: The confirmatory factor analysis revealed that the model was acceptable, and the analyses for known-group validity revealed statistically significant differences in all factors and the total scale of the Nurse Professional Competence scale short form. Internal consistency revealed that Cronbach's alpha values exceeded 0.70 for all factors and the total scale. The Chinese language version of the Nurse Professional Competence scale short form has acceptable construct validity and good internal consistency.
