ABSTRACT
The purpose of this study is to test the mediating effects of cognitive reappraisal and expressive suppression in the relation between sleep problems and depression in college students. Participants were 375 undergraduate students recruited from nationwide universities. Sleep problems, cognitive reappraisal, expressive suppression, and depression were assessed by a self-report using web-based questionnaires. The data were analyzed using descriptive statistics, t-tests, Pearson’s correlations, and regression analyses in PROCESS macro version 4.1. The major findings are as follows. First, the average levels of sleep problems, cognitive reappraisal, expressive suppression, and depression were not significantly different as a function of gender. Second, greater sleep problems were associated with less use of cognitive reappraisal and higher depressive symptoms while the use of expressive suppression was not associated with sleep problems or depressive symptoms. Third, sleep problems were linked to greater depressive symptoms directly and indirectly by way of less use of cognitive reappraisal. The findings suggest that sleep problems and emotion regulation strategies may play important roles in preventing depression in college students.
