Young Adults’ Loneliness and Depression During the COVID-19 Pandemic: A Moderated Mediation Model

ABSTRACT

Since the outbreak of the COVID-19 pandemic in December 2019, millions of people have been infected with the disease. The COVID-19 pandemic also produced severe mental health problems, such as loneliness and depression. The present study aimed to examine the mediating role of cognitive reappraisal and moderating role of resilience in the relationship between young adults’ loneliness and depression during the pandemic by adopting a cross-sectional research approach. In March 2020, 654 young adults (18–29 years old) were recruited to complete the measures for loneliness, depression, emotion regulation, and resilience. Results found that loneliness was positively and moderately associated with depression (r = 0.531, p < 0.001), and that both loneliness and depression were separately negatively associated with cognitive reappraisal (r = −0.348, p < 0.001;r = −0.424, p < 0.001) and resilience (r = −0.436, p < 0.001;r = −0.419, p < 0.001). The results indicated that both loneliness and depression were not associated with expressive suppression (r = 0.067, p = 0.087;r = −0.002, p = 0.961). The moderated mediation model results revealed that only cognitive reappraisal partially mediated the relationship between loneliness and depression (b = −0.301;Boot 95% CI = −0.388, −0.215). In addition, the results of the moderated mediation model indicated that resilience moderated the association between loneliness and depression (b = 0.035, p < 0.001, Boot 95% CI = 0.014, 0.055), while also moderated the impact of cognitive reappraisal on depression (b = −0.031, p < 0.001, Boot 95% CI = −0.058, −0.005). These findings have practical implications that broaden our understanding of depression in young adults and shed light on how to enhance cognitive reappraisal and resilience as a means of combating depression in this age group during the COVID-19 pandemic.
