Making sense of a pandemic: Mindsets influence emotions, behaviors, health, and wellbeing during the COVID-19 pandemic.

Rationale: As the SARS-COV-2 virus spread across the world in the early months of 2020, people sought to make sense of the complex and rapidly evolving situation by adopting mindsets about what the pandemic was and what it meant for their lives.

Objective: We aimed to measure the mindsets of American adults over the first six months of the COVID-19 pandemic to understand their relative stability over time and their relationship with emotions, behaviors, experiences, and wellbeing.

Methods: American adults (N = 5,365) were recruited in early March of 2020 to participate in a longitudinal survey with follow-up surveys at 6-weeks and 6-months. Three mindsets that people formed about the COVID-19 pandemic were measured: 'the pandemic is a catastrophe', 'the pandemic is manageable' and 'the pandemic can be an opportunity'.

Results: In line with our pre-registered hypotheses, these mindsets were associated with a unique and largely self-fulfilling pattern of emotions (positive, negative), behaviors (healthy, unhealthy, and compliance with CDC guidelines), experiences (growth/connection, isolation/meaninglessness) and wellbeing (physical health, mental health, quality of life). Moreover, mindsets formed in the first week of the pandemic were associated with quality of life 6 months later, an effect that was mediated by emotions and health behaviors.

Conclusion: The mindsets that people adopted about the COVID-19 pandemic - that it is 'a catastrophe', 'manageable', or 'an opportunity' may explain some of the heterogeneity in the lived experiences of Americans through their self-fulfilling impact on peoples' emotions, health behaviors, and wellbeing.
