Rationale: Tracking the trajectory of people's emotional and behavioral reactions to the COVID-19 pandemic sheds light on how people cope with the emerging crisis, evaluates the impact of emotional reactions on preventive behaviors, and provides insights into how preventive behaviors can be encouraged and maintained in the long term. Objective: We addressed two related questions: How did emotions change across various stages of the COVID-19 pandemic, and to what extent were preventive behaviors predicted by emotional reactions and information acquisition? Methods: We conducted a four-wave longitudinal study in the United States and China across four stages of the pandemic: prepandemic, onset of viral outbreak, ongoing risk, and contained risk. We measured emotions, life satisfaction, preventive behaviors, acquisition of COVID-19 related information, and risk perceptions. We used the Emotional Recall Task (ERT) to investigate people's emotions. By allowing people to describe their emotional experience in their own words, the ERT evaluates each individual based on emotions relevant to their personal experience, making it more suitable for a wider range of contexts and social groups. Results: Boredom, anxiety, fear, and worry were common emotional reactions to the pandemic as it emerged. Surprisingly, participants' emotional experience did not mirror infection and death rates: Instead of negative emotions growing as the virus spread, emotions soon reverted back to normality. This pattern held regardless of whether the viral spread was contained. Consequently, people's preventive behaviors were predicted by fear, anxiety, and worry only at the onset of the viral outbreak. In contrast, actively acquiring information and knowledge about COVID-19 had a more enduring effect on the engagement of preventive behaviors in both countries. Conclusion: Our research suggests a possible life cycle of emotional reactions towards a pandemic and highlights the importance of people acquiring information and knowledge about the threat in containing its spread.
