About

Several lines of evidence suggest that unhealthy sleep patterns contribute to depressive symptoms through disruption of brain networks that regulate emotional functions. However, we do not yet know to what degree the emotion regulation brain network is modified by the restoration of sleep, or whether the degree to which a sleep intervention modifies these neural targets mediates reductions in other depressive symptoms including suicidality.

The overall aim is to test the efficacy of an established sleep intervention (Cognitive Behavioral Therapy for Insomnia (CBT-I)) in reducing depressive symptoms through improving emotion regulation brain function in individuals with elevated depressive symptoms and clinically meaningful sleep disturbance.

In this study, we will assess feasibility of recruitment and retention as well as target engagement. Target engagement is defined as the treatment effect on increasing mPFC-amydgala connectivity, and/or decreasing amygdala reactivity during emotion reactivity and regulation paradigms. Participants will be 70 adults experiencing at least moderate sleep disturbances and who also have elevated anxious and/or depressive symptoms. Emotion distress and sleep disruption will be assessed prior to, and weekly while receiving six Cognitive Behavioral Therapy for Insomnia (CBT-I) across a period of 8 weeks. CBT-I improves sleep patterns through a combination of sleep restriction, stimulus control, mindfulness training, cognitive therapy targeting dysfunctional beliefs about sleep, and sleep hygiene education. Using fMRI scanning, emotion regulation network neural targets will be assayed prior to and following completion of CBT-I treatment.
