Measuring patient-provider communication skills in Rwanda: Selection, adaptation and assessment of psychometric properties of the Communication Assessment Tool.

Objective: To identify, adapt and validate a measure for providers' communication and interpersonal skills in Rwanda.

Methods: After selection, translation and piloting of the measure, structural validity, test-retest reliability, and differential item functioning were assessed.

Results: Identification and adaptation: The 14-item Communication Assessment Tool (CAT) was selected and adapted.

Validity And Reliability Testing: Content validation found all items highly relevant in the local context except two, which were retained upon understanding the reasoning applied by patients. Eleven providers and 291 patients were involved in the field-testing. Confirmatory factor analysis showed a good fit for the original one factor model. Test-retest reliability assessment revealed a mean quadratic weighted Kappa = 0.81 (range: 0.69-0.89, N = 57). The average proportion of excellent scores was 15.7% (SD: 24.7, range: 9.9-21.8%, N = 180). Differential item functioning was not observed except for item 1, which focuses on greetings, for age groups (p = 0.02, N = 180).

Conclusion: The Kinyarwanda version of CAT (K-CAT) is a reliable and valid patient-reported measure of providers' communication and interpersonal skills. K-CAT was validated on nurses and its use on other types of providers may require further validation.

Practice Implication: K-CAT is expected to be a valuable feedback tool for providers in practice and in training.
