Sleep and Academic Performance in Undergraduates: A Multi-measure, Multi-predictor Approach

A sample of 1654 undergraduate students showed that sleep quality and sufficient sleep are significant predictors of academic performance.

• Sleep phase, morningness/eveningness preference, sleep deprivation, sleep quality, and sleep irregularity were significantly associated with academic performance measures.
• Among 15 potential predictors, five were identified as significant for end-of-semester marks: previous academic achievement, class attendance, sufficient sleep, night outings, and sleep quality.
• The model explained 14% of the variance in academic performance (R(2)=0.14).
• Self-reported sleep quality and frequency of sufficient sleep contributed independently to academic performance outcomes.
• Associations between academic achievement and other sleep variables lost significance when considering multiple predictors.
