DAYLight - Adults 18-30

STUDY BASICS

Are you 18 - 30 years old and experiencing depression? You may be eligible to participate in a research study to test the effects of bright light on mood and circadian function. Compensation provided.

STUDY PURPOSE

Bright Light Therapy is an evidence-based treatment for depression. We are conducting this study to learn more about how age and individual differences in retinal light responsivity impact the effect of light on emotional brain function in adolescents and adults. We hope that our findings will inform more personalized use of light therapy in depression.
