Abstract
Public health emergencies pose a threat to the physical and psychological health of residents. The changes in the use and management of the community environment, and the adoption of prevention and control measures, such as the quarantine policy, would have some impacts on the psychology of the residents, but the degree and mechanism of the impacts are still unclear. This research obtains data through a nationwide network questionnaire survey during the COVID-19 epidemic, and compares the linear and nonlinear models. Under the control of residents’ daily activities, the influence of the community environment on the psychological pressure of residents and its nonlinear characteristics in various lockdown periods are studied. The results show that the influence of community environment on residents’ psychological pressure is different in various stages of the lockdown, and the nonlinear characteristics generally exist in these influences, thus the nonlinear model can more accurately fit the influence of community environmental factors. This research provides evidence and methodological reference for more in-depth nonlinear research, and a basis for community planning and management in the face of public health emergencies.
