Abstract
Introduction
Latinx students are the largest ethnic/racial minority group in higher education, but are also the group least likely to graduate from a four-year institution. Research suggests that heightened stress perceptions may impede college students’ ability to perform well academically. Poorer sleep may compound the impact of stress on academic functioning. The present study examined the multiplicative effect of college-stress and actigraphy-measured sleep on academic cognitions within-and-across semesters.
Methods
209 Latinx college students (Mage=18.95; 64.4% female, 85.1% Mexican descent) were assessed in the spring of the first year of college (T1) and fall of the second year (T2). At T1, participants wore an actigraph watch for 7 nights to measure total sleep time, sleep efficiency, and sleep midpoint. College-stress was assessed at T1 using the College Stress Scale. At T1 and T2, participants completed the Behavioral-Emotional-Cognitive School Engagement Scale, the Academic Self-Efficacy Scale, and a scale assessing academic motivation. Confirmatory factor analysis (CFA) was conducted to assess the model fit of a two-factor model representing academic cognitions (engagement, self-efficacy, motivation) at T1 and T2. Latent variable path analysis models testing for moderation were conducted using Mplus.
Results
The CFA indicated excellent fit (χ2(5)= 2.91, p=.71, RMSEA=.00, CFI=1.00, TLI=1.01, SRMR=.02). College-stress was concurrently (β=-.19, p=.02), but not longitudinally, associated with academic cognitions. Sleep midpoint predicted academic cognitions at T1 (β=-.24, p<.01) and T2 (β=-.18, p=.03). Sleep efficiency (β=.18, p=.01) and sleep midpoint (β=-.17, p=.02) moderated associations between college-stress and T2 academic cognitions. Higher college-stress was longitudinally linked with lower academic cognitions for students with lower sleep efficiency (b=-.12, p=.01) and later sleep midpoints (b=-.14, p=.01).
Conclusion
Greater college-stress is concurrently linked with lower academic cognitions, whereas later sleep timing has both immediate and enduring consequences on students’ academic mindsets. The impact of college-stress on academic cognitions may depend on the quality and timing of sleep at the time of these stress perceptions. Programs that address stress reduction and sleep health may be promising interventions for improving academic well-being among first-year Latinx college students.
