Sleep quality and executive function: does emotion regulation and stress mediate this relationship in college students?
Sleep deprivation is a growing concern for many, especially college students. Increased demands from school, work, and personal obligations, could decrease socioemotional and psychosocial functioning. Previous research suggests poor sleep quality is associated with negative outcomes on executive functioning, emotion regulation, and stress. The current study examined the relationships between sleep quality, executive functioning, emotion regulation, and stress in a sample of college students (N=105). Results revealed sleep quality (b=.161, p=.000) and perceived stress (b=.632, p=.000) were associated with executive functioning; emotion regulation (b=-.018, p=.862) was not related to executive functioning. Sleep quality was found to be associated with stress (b=.229, p=.006), but was not significantly related to emotion regulation (b=-.009, p=.834). Separate mediating models revealed stress and emotion regulation did not mediate the relationship between sleep quality and executive functioning. Future research should examine comprehensive measures of sleep to understand the impact to stress and executive functioning in students.
