Abstract

Caffeine is extremely addictive and is consumed by over 78% of college students. Does this affect their GPA? The purpose of this meta-analysis was to evaluate the relationship between caffeine consumption and academic performance. To do this, we located 8 studies that reported correlations between caffeine consumption and academic performance. We coded these articles and recorded the effect sizes (Cohen’s d) for the relationship. The results of this study showed a moderate effect size between caffeine and academic performance (d = -.51). However, one study showed a very strong effect (d = -0.58) and a very large sample size (N = 7377). With this study omitted, the overall average weighted effect size decreased to d = -0.16. These results suggest that caffeine consumption has a small effect on academic performance or GPA in college students.
