The Saudi Board of Emergency Medicine (SBEM) is required to assign educators including program directors to supervise their residents. These educators may impact the residents' academic and clinical performances. After thorough review, we noticed that the current literature lacks information about the direct influence of emergency medicine educators on their residents' academic and clinical performances. The main purpose of this study is to assess the residents' confidence level, and to measure the program directors' satisfaction of the residents' performances during their SBEM training yearsin Riyadh hospitals. This concurrent mixed-methods study was conducted in nine training hospitals in Riyadh, Saudi Arabia, during the 2021-2022 academic year. For the quantitative aspect, a cross-sectional survey was used, based on a questionnaire administered to postgraduate year (PGY)-2 to PGY-4 SBEM residents (n=120) using a nonprobability convenient sampling technique. The survey aimed to assess residents' confidence in their academic and clinical performance, influenced by their educators. A Likert scale with a total of 25 items, covering the seven roles of the CANMEDs framework, was employed. This assessment utilized a published tool called the In-Training Evaluation Report. For the qualitative aspect, program directors' perspectives were gathered through one-on-one unstructured interviews (n=9), guided by theoretical saturation. A purposive sampling technique was employed to select program directors. The interview tool collected demographic data, including gender, years of experience, and training hospital, and included 17 open-ended questions to explore program directors' opinions. The result of mixed methods showed that both quantitative and qualitative data sets were divergent with all independent variables (resident's age, gender, and training level) with the exception of the training hospital which was convergent. Thus, the residents' confidence toward their academic and clinical performances induced by their institutional educators was high. However, the program directors indicated changes that related to residents' training level. The residents' confidence toward their academic and clinical performance induced by their institutional educators was high.The educators had a great deal of influence over the academic and clinical performance of the residents. However,the program directors thought there were some issues with the performance of the residents.Most of the program directors also believed that several influential factors that may have affected the residents' overall performance includestress and receiptof constructive feedback.
