Abstract
In this study, we examine how perceived vulnerability to disease, psychological resilience, and disgust sensitivity are affected by changing social conditions during the pandemic. We collected data from 314 participants at four different time points, reflecting varying government restrictions and actual morbidity/fatality rates. We found that disgust sensitivity and psychological resilience remained robust to changing social conditions. However, perceived vulnerability to disease fluctuated over time. People reported feeling more vulnerable when external conditions were inconsistent, such as high case numbers with low government restrictions or vice versa. Pathogen disgust sensitivity emerged as the primary predictor of perceived vulnerability to disease dimensions: Perceived Infectability and Germ Aversion. Psychological resilience showed only a weak relationship with Germ Aversion. In conclusion, the traits that influence how we cope in threatening environment, namely disgust sensitivity and psychological resilience, remain unaffected by the social conditions during the pandemic. Perceived vulnerability to disease, on the other hand, is more sensitive to environmental changes and can be partially predicted by disgust sensitivity and psychological resilience. Notably, although both disgust sensitivity and perceived vulnerability to disease are parts of the behavioural immune system, they differ in their response to environmental factors. Disgust sensitivity remains stable over time, regardless of the government restrictions or pandemic cases, whereas perceived vulnerability to disease is influenced by the external factors.
