Effects of Brief Cognitive Behavioral Therapy for Insomnia on Improving Depression Among Community-Dwelling Older Adults: A Randomized Controlled Comparative Study.

Background: Cognitive behavioral therapy for insomnia (CBT-I) has been shown to improve depressive symptoms in older adults with comorbid insomnia and depression. However, it remains unclear whether brief CBT-I is effective for improving depressive symptoms in community-dwelling older adults with insomnia symptoms of varying severity.

Aim: This study sought to examine the effectiveness of a brief CBT-I intervention delivered by public health nurses to improve depressive symptoms among older adults recruited from a community setting.
