This paper reports on a psychometric study conducted to explore the factor structure and refine the Critical Cultural Competence Scale (CCCS). Critical Cultural Competence (CCC) functions to promote the safety, equity, and well-being of patients, their families, and health care professionals. The development process of this measurement scale was systematic and iterative, and included generating a pool of potential items based on the theoretical definitions of CCC. In this study, conducted with a sample of 170 registered nurses from British Columbia, Canada, we used Principal Component Analysis (PCA) to explore the factor structure of the initial set of 84 items as a final step in developing the CCCS. The final version of the measure consists of 43 items, and the PCA results supported a four-factor solution consistent with the theoretical underpinnings of the scale. Future research is recommended to further assess the construct validity of this newly created scale.
