How social support and resilience impact mental health: The moderating role of time in isolation during the COVID-19 pandemic

During the COVID-19 pandemic, quarantines effectively prevented the spread of COVID-19 but also caused people to develop mental health problems. We thus aimed to verify the impact of social support and resilience on mental health and to uncover the moderating role played by time in isolation during the post-pandemic era. We administered a cross-sectional survey to 510 college students. The results found that social support directly and negatively predicted mental health problems, and this relationship was mediated by resilience. Through multigroup analysis, resilience partially mediated the relationship between social support and mental health during period of isolation 1 (PI1) and fully mediated this relationship during period of isolation 2 (PI2) and period of isolation 3 (PI3). Moreover, the path coefficient of resilience to mental health at T3 was significantly higher than that at T2. Thus, the effect of resilience on mental health increases with the duration of time in isolation.
