Abstract
While the issue of behavioral change is of increasing interest to academics and practitioners, an understanding of its drivers remains limited. Consistent with the possibility that destabilizing events can trigger the implementation of beneficial changes in one's life, this research studies the COVID-19 pandemic and its influence on the adoption of positive habits. More specifically, it focuses on positive health and lifestyle-related behavioral changes observed within the confined population, as well as the antecedents of such changes. Two surveys conducted 1 month apart in an urban setting severely affected by the pandemic confirm the role of optimism toward the crisis as an antecedent to four changes: slowdown in pace of life, decluttering of personal space, reflection on consumption habits and adoption of healthy behaviors. Collective resilience, social support and anxiety are identified as determinants of optimism. Results suggest an evolution of certain relations including the increase of collective resilience effect on optimism over time.
