Abstract
Sleep quality is correlated with physical and mental health and is an important target for overall
well-being. CBT-I is an evidence-based strategy to improve sleep quality; however, shortage of
qualified providers, logistical issues such as cost, travel, and time, privacy concerns, and a desire
to resolve symptoms on one’s own limit access to CBT-I. Compared to traditional face-to-face or
web-based delivery of CBT-I, app-delivered CBT-I may be an efficacious alternative capitalizing
on the portability, privacy, and accessibility of mobile phones. The present study examined the
effectiveness of the CBT-I Coach for educating participants about the importance of healthy
sleep practices and dysfunctional beliefs about sleep, and targeted sleep quality among college
students. Results indicated use of the CBT-I Coach resulted in significant improvements in sleep
quality (t(21)= 4.38, p<.001, d=0.93), dysfunctional beliefs about sleep (t(21)=3.12, p=.001,
d=0.66), sleep hygiene behaviors (t(21)=3.26, p=.001, d=0.70), and sleep efficiency (t(21)=4.93,
p<.001, d=1.05). This study provides new evidence that the use of the CBT-I Coach has the
potential to be an effective intervention in improving sleep quality in college students.
