Optimism and pessimism were prospectively associated with adaptation during the COVID-19 pandemic

Using longitudinal data from the Health and Retirement Study, we examined the association between optimism/pessimism before the pandemic and adaptation during the COVID-19 pandemic. Overall, optimism was associated with behaviors that reduce COVID-19 transmission and higher psychological well-being (βs>|.196|) through changes in social contacts (indirect effect βs> |.004|) and/or increases in physical activity (βs=|.01|). Separating optimism and pessimism, we found that only pessimism was associated with behaviors that reduce risk, but both optimism and pessimism were associated with psychological well-being. By investigating them in the context of new public health challenges, we found that while the presence of optimism and absence of pessimism may both be resources for well-being, the absence of pessimism may be particularly important for health-relevant behaviors. © 2024 Elsevier Inc.
