Cross-cultural adaptation and validation of two crisis resource management scales

Background: Simulation training programs in crisis resource management must be evaluated using valid and reliable instruments. We translated into Spanish and linguistically validate The Mayo High Performance Teamwork Scale (MHPTS) and Ottawa Crisis Resource Management Global Rating Scale (Ottawa GRS) non-technical skills assessment instruments. Method: We performed a standardised cross-cultural adaptation process. The psychometric properties of both instruments in their versions adapted to Spanish were subsequently evaluated in a sample of 100 students by using exploratory factor analysis and assessing internal consistency and convergent validity through a total of 94 simulation scenarios in urgent medical situations. Results: Our results for the MHPTS showed a one-dimensional structure containing 8 items which explained a total variance of 72.84%; the Ottawa GRS also had a one-dimensional structure, this time with 5 items, which explained a total variance of 91.79%. According to the Cronbach alpha, the internal consistency for the MHPTS was 0.94 (1–8 items) and 0.98 for the Ottawa GRS. In addition, there was a strong correlation between the MHPTS and Ottawa GRS (r = 0.97; p < 0.001). Conclusion: We found strong evidence for the high validity and reliability of the Spanish versions of both these tools when tested in Spanish simulated emergency contexts
