Revision and Psychometric Testing of the Intercultural Competence Scale.

ABSTRACT

Background and Purpose: Given the broad availability of instruments developed to assess cultural competence, there is a need to develop psychometric properties of existing instruments so they might be adapted accordingly. The purpose of this study was to conduct a psychometric evaluation of the Intercultural Competence Scale (ICS) to ensure its validity and reliability of measurement. Methods: The psychometric evaluation included scale selection and construction, psychometric testing, and instrument validation. Data analysis methods included item analysis, internal consistency reliability, and exploratory factor analysis. Results: Participants in this longitudinal study included 215 nursing students from a selected university. The ICS adopted three instruments modified into a 21-item tool. Conclusion: This study provides a foundation for future research to develop a modified instrument for measuring cultural competence.
