Poor sleep quality negatively impacts academic performance for students with a full course load. This highlights the importance of sleep quality for student success, especially under demanding academic conditions.

Area of Science:

  • Psychology
  • Sleep Science
  • Academic Performance

Background:

  • Student academic success is influenced by various factors, including sleep.
  • Existing research has explored the link between sleep and academic outcomes, but findings can be inconsistent.
  • Understanding the specific relationship between sleep quality and academic performance is crucial for student well-being and achievement.

Purpose of the Study:

  • To investigate the association between sleep propensity (Epworth Sleepiness Scale) and sleep quality (Pittsburgh Sleep Quality Index) with academic performance (GPA and grades).
  • To determine if these associations differ based on academic load.
  • To explore the moderating influence of daytime functioning demands.

Main Methods:

  • Surveyed 414 students using the Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index.

  • Collected academic data including GPA and grades in introductory psychology.
  • Analyzed data to identify correlations between sleep measures and academic performance.

    • Main Results:

    • No significant correlation was found between sleep propensity or quality and academic performance in the total student sample.
    • A significant negative association emerged for students carrying a full course load: poorer sleep quality correlated with lower academic performance.
    • These findings suggest a conditional relationship between sleep quality and academic outcomes.

    Conclusions:

    • Sleep quality, not just propensity, is a critical factor in academic performance, particularly under high academic demand.
    • The overall demands of daytime functioning may moderate the relationship between sleep quality and academic success.
    • Further research should explore these moderating factors to develop targeted interventions for students.
