Background:
Although it is known that social support can promote post-traumatic growth (PTG) of trauma survivors, the specific mechanism is still unclear in the case of government policy intervention and large-scale population infection with COVID-19.
Methods:
Through snowballing sampling from January 7 to February 13, 2023, we collected data from 1381 patients tested positive for COVID-19, excluding asymptomatic or undiagnosed cases. Participants completed effective scales measuring social support, PTG, and proactive coping behaviors. Multiple linear regression and mediation analysis were used to process the data.
Results:
Social support significantly predicted PTG (β=0.26, p<0.001), with proactive coping mediating 44.7% of this effect. About 32.66% of COVID-19 patients reported a medium-to-high level of PTG.
Conclusion:
This study uniquely captures the PTG dynamics during China's sudden policy transition, demonstrating the positive role of social support in PTG and emphasizing that proactive response is a key intervention goal for public health crises.
