Abstract

Background: Few valid and reliable measures exist for health care professionals interested in determining their levels of cultural and linguistic competence.

Objective: To evaluate the measurement properties of the Cultural Competence Health Practitioner Assessment (CCHPA-129).

Methods: The CCHPA-129 is a 129-item web-based instrument, developed by the National Center for Cultural Competence. Responses on the CCHPA -129 were examined using factor analysis; Rasch modeling; and differential item functioning across race, ethnicity, sex, and profession.

Subjects: A total of 2504 practitioners, including 1864 nurses (RN/LPN/BSN); 341 clinicians (PA/NP); and 299 physicians (MD/DO), who completed the CCHPA-129 online between 2005 and 2008.

Results: Three factors representing domains of Knowledge, Adapting Practice, and Promoting Health for culturally and linguistically diverse populations accounted for 46% of the variance. Among Knowledge factor items, 53% (23/43) fit the Rasch model, item difficulties ranged from −1.01 logits (least difficult) to +1.11 logits (most difficult), separation index (SI) 13.82, and Cronbach’s α 0.92. Forty-seven percent (21/44) Adapting Practice factor items fit the model, item difficulties −0.07 to +1.11 logits, SI 11.59, Cronbach’s α 0.88; and 58% (23/39). Promoting Health factor items fit the model, item difficulties −1.01 to +1.38 logits, SI 22.64, Cronbach’s α 0.92. Early evidence of validity was established by known groups having statistically different scores.

Conclusions: The 67-item CCHPA-67 is psychometrically sound. This shorted instrument can be used to establish associations between practitioners’ cultural and linguistic competence and health outcomes as well as to evaluate interventions to increase practitioners’ cultural and linguistic competence.
