Insomnia Related to Specified Disorder Parkinson Disease | Behavioral: CCBT-I Group Behavioral: Control Group | Not Applicable |
The investigators propose a randomized (1:1 ratio), single-blind, parallel-group, controlled study on Computerized cognitive behavioral therapy for insomnia (CCBT-I) treatment for PD patients which evaluates clinical and sleep variables before and after 6-week CCBT-I.
28 subjects with idiopathic PD having insomnia will be recruited for this study. Insomnia will be defined by >11 Insomnia Severity Index (ISI) scores as 11 was found in a study examining sensitivity/specificity for ISI cutoffs to be highest % correctly identified in clinical sample.
After a screening visit, the patients will be randomized to either the CCBT-I 6-week treatment arm or the control treatment arm. At the end of the screening patients will also receive 2 enveloped packages of questionnaires to be completed at Week 8 and Week 12 (after baseline) at home and mailed back to the Principal Investigator (PI) at the study center. The patients will get a follow-up phone call every week for the treatment period and during Week 8 and Week 12 to remind them to complete evaluations and mail back to the PI.
The Cleveland Clinic Wellness Institute will also send weekly email prompts to the participants in the CCBT-I treatment arm to ensure/improve compliance with the online sleep program.

Experimental: CCBT-I Group
The patients who will be randomized to CCBT-I group will get Cleveland Clinic CCBT-I program through the internet (Cleveland Clinic Wellness Go! To Sleep six-week online program). The program involves a 6-week effective sleep therapy, an online sleep log and daily sleep score, six specially crafted relaxation practices, daily sleep improvement recommendations, activities to help the patient get the sleep needed, daily e-mails from the patient's program coach, daily articles to help the patient get the most out of the program and a mobile application for easy sleep tracking.
|
Behavioral: CCBT-I Group
Every patient will have a unique password to access to CCBT-I. The program consists of 5 cores: sleep log, day's lesson, activities, relaxation and progress. Each day, the patients fill in sleep logs before getting the day's lesson. Filling sleep log will be reminded daily by the program coach from Sleep Center. |
Active Comparator: Control Group
The patients who will be randomized control group will be given a reading material only including recommendations about sleep hygiene, stimulus control and sleep restriction. The control group will have access to the CCBT-I program through the internet (Cleveland Clinic Wellness Go! To Sleep six-week online program), if proven effective, after the study is completed. To identify PD-specific barriers to Internet usage and CCBT-I, all patients at the end of the study or at the time of drop out will have a questionnaire on the barriers to CCBT-I. |
Behavioral: Control Group
Reading material only including recommendations about sleep hygiene, stimulus control and sleep restriction. Access to the CCBT-I program through the internet (Cleveland Clinic Wellness Go! To Sleep six-week online program), if proven effective, after the study is completed. |
- Insomnia Severity Index [ Time Frame: 12 weeks ]To demonstrate a significant difference in the mean Insomnia Severity Index (ISI), from baseline to Week 12 among subjects randomized to CCBT-I treatment versus the control group
- Pittsburgh Insomnia Rating Scale [ Time Frame: 12 weeks ]To demonstrate a significant difference in the mean Pittsburgh Insomnia Rating Scale (PIRS-20) from baseline to Week 12 among subjects randomized to CCBT-I treatment versus the control group
- Total Sleep Time [ Time Frame: 12 weeks ]To demonstrate a significant increase in Total Sleep Time (TST) in PD subjects, from baseline to Week 12, who were randomized to CCBT-I via daily sleep logs in the online program as compared to the control group
- Patient Global Impression of Improvement [ Time Frame: 12 weeks ]To demonstrate a significant difference in the number of patients who significantly improved based on Patient Global Impression of Improvement (PGI-I) from baseline to Week 12 among subjects randomized to CCBT-I treatment versus the control group
- Fatigue Severity Scale [ Time Frame: 12 weeks ]To demonstrate a significant difference in the mean Fatigue Severity Scale (FSS), from baseline to Week 12 among subjects randomized to CCBT-I treatment versus the control group
- Epworth Sleepiness Scale [ Time Frame: 12 weeks ]To demonstrate a significant difference in the mean Epworth Sleepiness Scale (ESS), from baseline to Week 12 among subjects randomized to CCBT-I treatment versus the control group
