Purpose:
This study aimed to examine the effect of an email delivered version of Cognitive Behavioral Therapy for Insomnia (CBT-I) in college students with insomnia.
Design And Methods:
The study used a two-group pre- and postdesign (N = 63). The intervention group received 6 weekly, email-delivered CBT-I sessions, and the comparison group received a link to a student wellness website for healthy sleep information.
Findings:
The intervention group demonstrated significant improvement in attitudes toward sleep, sleep quality, sleep hygiene, and daytime sleepiness from pretest to posttest. Furthermore, the intervention group showed more positive outcomes, compared to the comparison group at the posttest.
Practice Implications:
An email-delivered sleep intervention is a feasible and easy-to-use tool that nurses can utilize to promote sleep quality among college students.
