Sleep and Depression (SAD) Laboratory
About Us
The Sleep and Depression Lab is located in the Department of Psychology at Toronto Metropolitan University and is directed by Dr. Colleen Carney. We research sleep disorders, such as insomnia, and the relationship between sleep and mood disorders – most notably, depression. In our clinical trials, we are currently investigating the treatment and maintenance of insomnia symptoms through Cognitive Behavioural Therapy for Insomnia (CBT-I).
Research Focus
Teen Sleep
In the SAD Lab, we are interested in investigating how to improve access to care for adolescents and young adults (AYAs) with poor sleep through the use of an app called DOZE.
Cognitive Behaviour Therapy for Insomnia in those with Depression
Did you know that insomnia can complicate depression because it: 1. often remains after recovering from depression 2. interferes with successful depression treatment response 3. makes it more likely that depression will return
