Abstract The COVID-19 pandemic is a CBRNE disaster that has spread over a long period and induced a major impact not only on public health but also on lifestyle. This study used the recovery calendar assessment to examine people’s adaptation to coexistence with COVID-19 and to identify the factors related to the adaptation. A total of 1,000 respondents from across Japan were recruited through a web survey based on population distributions of age, gender, and residential area. This study measured psychological resilience, risk perception, habit of infection preventive behavior, and adaptation to COVID-19. Survivorship curve analyses showed that the probability of reaching adaptation milestones increased over time and in response to salient social events during the pandemic, and more than 50% of the respondents adapted to coexistence with COVID-19 more than 2 years after the first wave of the pandemic. Moreover, Cox regression analyses indicated that risk perception, psychological resilience, and habit of infection prevention behaviors were associated with the adaptation process. Particularly, psychological resilience and the habit of infection behaviors were important personal factors that encourage proactive coexistence with COVID-19. This study proposes an assessment framework for examining the temporal process of adaptation to prolonged disasters and the importance of understanding multidimensional factors, such as time course, social events, and personal factors to develop adaptation to prolonged CBRNE disasters.
