This brief communication reports preliminary findings of a study conducted to investigate the relationship between probability discounting and people’s adherence to preventive behaviors recommended during the COVID-19 pandemic. A sample of 112 adults living in Brazil completed an online survey composed of a Probability Discounting Questionnaire (PDQ) and a 10-item assessment of how often they complied with the health authorities’ recommendations (e.g., wash the hands frequently, practice social distancing, stay at home as much as possible, wear a mask when in public). Data analysis included the participants who showed higher (n = 40) and lower (n = 40) adherence to preventive behaviors. Results revealed that probability discounting measures are related to people’s preventive actions. Participants in the higher adherence group present significantly larger risk aversion indices (i.e., larger h values) than participants in the lower adherence group. Also, participants who showed lower adherence to preventive behaviors were more likely to perform risky choices in the PDQ than participants who demonstrated higher compliance with health authorities’ recommendations. These preliminary results suggest that probability discounting can play an essential role in people’s self-protective decisions during a global health emergency, such as the COVID-19 pandemic.
