Abstract: Objective To understand the knowledge gain and psychological status of residents of standardized training program on the emerging coronavirus pneumonia (COVID-19), to provide a reference to the teaching departments of the school for development of methods to improve capacity building of trainees. Methods A questionnaire survey was implemented and.154 trainees from three hospitals affiliated to Army Medical University participated in this investigation by questionnaires star platform. Data was collected and analyzed by Excel and SPSS 22.0. Results It was found that 72.7% (112/154) of the trainees believed that the improvement of their awareness about COVID-19 pandemic and their personal protection skill was mainly learnt from training courses organized by the hospital in the early stage of the pandemic; 85.7% (132/154) of them believed that skill training significantly improved personal protection skills, and 95.5% (147/154) of them believed that it was very important to strengthen the training on these infectious diseases. The results also showed that 55.2% (85/154) of the trainees suffered from different degrees of anxiety. The incidence of moderate-to-severe anxiety was much lower among those who believed the pandemic was preventable(χ²=24.8, P＜0.05);Among the trainees who participated in skill training more than two times, the incidence of moderate-to-severe anxiety is lower than those who participated in the protection skill training less than 2 times( χ²=11.9, P＜0.05); The better the mastery of the new coronary pneumonia protection skill,the lower is the incidence of moderate-to-severe anxiety as compared to the individuals with poor knowledge(χ²=13.7, P＜0.05), while there was no significant correlation between the degree of education, grade, major and anxiety status. Conclusions In the early stage of the COVID-19 pandemic, most of the trainees receiving standardized resident training are not well trained with the protection skill against to deal with acute contagious diseases,thus the knowledge and skills training related to the COVID-19 pandemic organized by the hospital is necessary. Facing an emerging pandemic, the incidence of anxiety is high in resident training trainees and the teaching management department needs to pay attention to their mental health and provide necessary psychological support including personal consultation.
