Valid and reliable instruments to measure and assess cultural competence for oral health care providers are scarce in the literature, and most published scales have been contested due to a lack of item analysis and internal estimates of reliability. The purposes of this study were, first, to develop a standardized instrument to measure dental students’ knowledge of diversity, skills in culturally competent patient‐centered communication, and use of culture‐centered practices in patient care and, second, to provide preliminary validity support for this instrument. The initial instrument used in this study was a thirty‐six‐item Likert‐scale survey entitled the Knowledge, Efficacy, and Practices Instrument for Oral Health Providers (KEPI‐OHP). This instrument is an adaption of an initially thirty‐three‐item version of the Multicultural Awareness, Knowledge, and Skills Scale‐Counselor Edition (MAKSS‐CE), a scale that assesses factors related to social justice, cultural differences among clients, and cross‐cultural client management. After the authors conducted cognitive and expert interviews, focus groups, pilot testing, and item analysis, their initial instrument was reduced to twenty‐eight items. The KEPI‐OHP was then distributed to 916 dental students (response rate=48.6 percent) across the United States to measure its reliability and assess its validity. Both exploratory and confirmatory factor analyses were conducted to test the scale's validity. The modification of the survey into a sensible instrument with a relatively clear factor structure using factor analysis resulted in twenty items. A scree test suggested three expressive factors, which were retained for rotation. Bentler's comparative fit and Bentler and Bonnett's non‐normed indices were 0.95 and 0.92, respectively. A three‐factor solution, including efficacy of assessment, knowledge of diversity, and culture‐centered practice subscales, comprised of twenty‐items was identified. The KEPI‐OHP was found to have reasonable internal consistency reliability to warrant its use for baseline and repeated measures in assessing changes in dental students’ growth in cultural competence across four‐year dental curricula.
