Development and Psychometric Evaluation of the Clinical Nursing Cultural Competence Scale.

Cultural competence in clinical nurses can lead to comprehensive care for patients from different cultures. Currently, an appropriate instrument to assess cultural competence in clinical nurses is limited. This study aimed to design and determine the psychometric properties of the clinical nursing cultural competence scale (CNCCS). This methodological study was conducted in 2018-2019 in two phases. In the first phase, a literature review and semistructured interviews with 18 clinical nurses from Isfahan and Ahvaz were conducted, and the results were used for item generation. In the second phase, the face, content, construct validity, and reliability of the questionnaire were assessed. For construct validity assessment through exploratory factor analysis (EFA), 200 clinical nurses were purposefully recruited to fill out CNCCS. In the first phase, 140 items were produced. In the second phase, the item number was reduced to 40 after the face and content validity assessment. In EFA for construct validity assessment, 13 more items were deleted, and the remaining 27 items were loaded on six factors. The Cronbach's alpha and the test-retest intraclass correlation coefficient were CNCCS 0.86 and 0.93, respectively. The CNCCS had acceptable psychometric characteristics in Iranian nurses and can be used for assessing cultural competence among clinical nurses. The use of this scale can help nursing policymakers and managers develop their understanding of nursing cultural competence and develop strategies for its improvement.
