Ongoing sleep disturbances have been connected with more severe depression (McGlinchey & Portillo, 2016), such that intensity of depressive symptoms is associated with individuals experiencing worse sleep quality. This study examined the relationship between participant sleep quality at baseline, as measured by total score on the Pittsburgh Sleep Quality Index (PSQI), and change in depression symptoms after participants completed a six-week, internet-based cognitive-behavioral therapy (iCBT) program. Data from 19 UCLA undergraduate and graduate students who were diagnosed with mild to moderate depression and completed the iCBT program were examined. A repeated-measures ANOVA demonstrated a significant decrease in depression severity after the iCBT program [F(1,17)=7.30, p.05). Additionally, there were no observed differences in sleep quality or treatment outcomes across genders or student status. Future studies may examine the efficacy of a new, targeted component of iCBT to improve sleep quality and potential benefits on reducing depression. -- *Kaitlyn Pham* Certified STAND Peer | RPN Intern Research Assistant | Depression Grand Challenge | Child First Lab UCLA Class of 2021.
