Institutional Trust as a Protective Factor during the COVID-19 Pandemic in China.

Previous research has demonstrated that institutional trust protects subjective well-being during pandemics. However, the potential mediation mechanisms underlying this linkage remain unclear. This study constructs a mediating model to investigate the effect of institutional trust on subjective well-being and the mediating roles of belief in a just world and fear of COVID-19 in the Chinese context. To this end, we survey a sample of 881 participants. The results show that institutional trust, belief in a just world, fear of COVID-19, and subjective well-being (i.e., life satisfaction, positive affect, and negative affect) are significantly interrelated. The results also indicate a significant impact of institutional trust on life satisfaction, positive affect, and negative affect. Belief in a just world and fear of COVID-19, independently and in sequence, mediate the relationship between institutional trust and subjective well-being.
