Addressing the Problem of Student- Athlete Sleepiness: Feasibility of Implementing an Interactive Sleep Workshop at a Division I School

Emily Kaier, Danielle Zanotti, Joanne L. Davis, Kathleen Strunk, and Lisa DeMarni Cromer

Sleep concerns are prevalent among student-athletes and can result in impaired athletic and academic performance. The current study investigated the feasibility and effectiveness of a brief sleep workshop for student-athletes. Athletes (N = 152) completed baseline and follow-up questionnaires (n = 104) after the intervention. Greater than half of the athletes (51%) who attended the workshops and followup reported at least one change in sleep behaviors. Results revealed a significant decrease in sleepiness from baseline to follow-up and an improvement in daytime functioning. Although athletes reported an increase in problematic sleep hygiene behaviors, they recorded significant increases in sleep knowledge from baseline to follow-up, which was maintained at the second follow-up. These longitudinal data provide evidence that a brief psychoeducation sleep workshop for student-athletes is promising for improving sleep knowledge and daily functioning.
