Background - Clinical simulations provide an opportunity to assess students' patient-centered communication. The purpose of this study was to further validate the Health Communication Assessment Tool© (HCAT) with international and interprofessional health care educators.

Methods - A total of 218 educators watched an online video of a simulation and assessed a student's communication behaviors using the HCAT.

Results - Exploratory factor analysis revealed a five-factor model. The average intraclass correlation of these factors was high (intraclass correlation coefficient [ICC] = 0.99), whereas the single-measure consistency ICC was moderate (ICC = 0.41).

Conclusions - Analysis of the HCAT using interprofessional, international simulation educators provided further evidence of the instrument's reliability and validity.
