 The research was about the relationship between levels of psychological stress before the corona epidemic as related to subsequent corona-related symptoms. The most important findings of the study are that the level of anxiety prior to the corona epidemic was predictive of subsequent corona-related symptoms. Depression and stress were also related, but the strongest association was found for anxiety. It's important for society because it's important to know who is the high-risk and low-risk for coronavirus infection. We find that people with high levels of distress, particularly anxiety, are at the highest risk for developing corona symptoms and possibly coronavirus infection. Psychological stress is related to adverse health behaviors, such as smoking, alcohol consumption, poor diet and physical activity. We want to look into how psychological factors affected these health behaviors during the corona epidemic.
