Family plays a pivotal role in individuals' mental health. During the COVID-19 epidemic, people were being quarantined at home to prevent the further spread of the virus. Therefore, the influence of family on individuals is more significant than usual. It is reasonable to assume that family cohesion can effectively alleviate the stress consequences during the COVID-19 epidemic. In the present study, a moderated mediation model was constructed to examine the mechanisms underlying the association between family cohesion and stress consequences among Chinese college students. A large sample of Chinese college students (N = 1,254, M_age = 19.85, SD_age = 1.29) participated in the study. Results indicated that family cohesion was negatively related to stress consequences. Fear of COVID-19 partially mediated the link between family cohesion and stress consequences. Excessive affective empathy reported by participants served to aggravate the relation between fear of COVID-19 and stress consequences. The study helps us understand how internal and external factors affect individual mental health that provides meaningful implications for promoting mental health.

Previous studies have found that adverse childhood experiences can lead to depressive symptoms. But the underlying mechanisms have not been determined. Guided by the 3-P model of insomnia and acceptance and commitment therapy, this study examined the mediating role of poor sleep quality and psychological inflexibility in the relationship between adverse childhood experiences and depressive symptoms during the COVID-19 pandemic. A total of 996 senior high school students in China (Mage = 16.57 years; SD = 1.03) completed the self-report measures of adverse childhood experiences, depressive symptoms, poor sleep quality, and psychological inflexibility. Multiple mediation analysis revealed that adverse childhood experiences were related to depressive symptoms through poor sleep quality and psychological inflexibility, serially. These findings point to potential targets in the prevention of and intervention in adolescent depressive symptoms.
