Objective measurement of simulation performance requires a validated and reliable tool. However, no published Italian language assessment tool is available. Translation of a published English language tool, the Ottawa Crisis Resource Management Global Rating Scale (GRS), may lead to a validated and reliable tool. After developing an Italian language translation of the English language tool, the study measured the reliability of the new tool by comparison with the English language tool used independently in the same simulation scenarios. In addition, the validity of the Italian language tool was measured by comparison to a skills score also applied independently. The correlation coefficient between the Italian language overall GRS and the English language overall GRS was 0.82 (adjusted 95 % confidence interval: 0.62-0.92). The correlation coefficient between the Italian language overall GRS and the skill score was 0.85 (adjusted 95 % confidence interval 0.68-0.94). This study demonstrated that the Italian language GRS has acceptable reliability when compared with the English language tool, suggesting that it can be used reliably to evaluate the performance during simulated emergencies. The study also suggests that the tool has acceptable validity for assessing the simulation performance. The study suggests that the Italian language GRS translation has reasonable reliability when compared with the English language GRS and reasonable validity when compared with the assessment of the skills scores. Data suggest that the instrument is adequately reliable for informal and formative type of examinations, but may require further confirmation before use for high-stake examinations such as licensing.
