Optimistic Youth: Young Adults Predicted a Faster Decrease in Risk during COVID-19 Emergency State in Portugal

Perception of risk is known to change throughout the lifespan. Previous studies showed that younger adults are more prone to risk behaviours than older adults. Do these age-related differences influence risk perception during a pandemic crisis? Here, we investigated how age influenced predicted risk during the COVID-19 emergency state in Portugal. We show that time-projected estimations (e.g., appraisals based on ‘now’ vs. ‘in two weeks’ time', or ‘in four weeks’ time') of both risk behaviour and importance of transmission prevention decrease over time. Importantly, projected risk decreased more steeply for younger than older adults. Our findings suggest that younger adults have a different perception of epidemic-related risk than older adults. This seems to support the view that public health policy making during epidemics should differentially target younger adults.
