CBT-I Improves Sleep and Co-Morbid Depression

Insomnia commonly presents with comorbid depression and often persists following depression remission. Cognitive behavioral therapy for insomnia (CBT-I) has been shown in several studies to improve both insomnia and depressive symptoms.

A new study examined the effects of digital CBT-I on insomnia and depressive symptoms. All participants met criteria for insomnia and had clinically significant depression. The results indicated that CBT-I significantly improved insomnia and depressive symptoms. The results suggest that effects of digital cognitive behavioral therapy for insomnia extend to improving depressive symptoms in those with clinically significant depressive symptomatology. The results suggest that CBT-I may be an important therapy to assist in the management of depressive symptoms in patients with comorbid insomnia.
