Internet Cognitive Behavioral Therapy for Insomnia to Prevent Cardiovascular Disease

January 7, 2021

Overview

The Internet Cognitive Behavioral Therapy for Insomnia to Prevent Cardiovascular Disease study aims to test the effectiveness of internet-based cognitive behavioral therapy to reduce risk of cardiovascular disease among adults aged 40 to 64 who also suffer from chronic insomnia. 

 

Study Information 

Participants who meet study criteria will complete a questionnaire and then undergo a physical examination. Their cardiovascular health will be assessed as well. Patients who complete these initial tasks will then need to wear a wrist actigraph to monitor their sleep over the next 7 nights and fill out an online sleep diary. 

 

After completing the sleep assessment, patients will be assigned to undergo internet based CBT or to a control group. Both groups will fill out sleep diaries for the duration of the trial. At the end of the study, patients who were in the CBT group will be scheduled for an 8-week follow-up appointment where they will complete additional questionnaires and undergo a cardiovascular health assessment.
