Factors associated with the mental health status of medical students during the COVID-19 pandemic: a cross-sectional study in Japan.

This study identified that self-efficacy and self-esteem were both influential factors for predicting psychological distress during the current COVID-19 pandemic. Medical schools should provide support for mental health and educational initiatives directed at enhancing self-esteem and self-efficacy, with a focus on improving personal resilience. In emergency situations, such as that faced in response to the COVID-19 pandemic, initial programmes might target students with higher levels of self-efficacy. By contrast, under routine situations, these efforts should be directed towards students with lower self-esteem as primary means to prevent depression.
