Purpose To determine whether Mindfulness-Based Treatment for Insomnia (MBTI) is more effective in the treatment of chronic insomnia disorder (CID) in patients with multiple sclerosis (MS) when compared with standard sleep hygiene counseling.
Specific Aims / Hypotheses
Our specific aims are to determine:
- Whether MBTI is more effective than standard sleep hygiene counseling in improving objectively-measured sleep quality among this group of MS patients with CID, as measured by the Fitbit Charge 2 activity tracker.
- Whether MBTI is more effective than standard sleep hygiene counseling in improving self-reported sleep quality among this group of MS patients with CID, as measured by the Pittsburgh Sleep Quality Index (PSQI).
- Whether MTBI is more effective than standard sleep hygiene counseling in reducing self-reported severity of insomnia among this group of MS patients with CID, as measured by the Insomnia Severity Index (ISI).
- Whether MBTI is more effective than standard sleep hygiene counseling in improving self-reported quality of life among this group of MS patients with CID, as measured by the Multiple Sclerosis Quality of Life Inventory (MSQLI).
We hypothesize that among study participants with MS and CID:
- MBTI will improve their objectively-measured sleep quality, as measured by the Fitbit Charge 2 activity tracker.
- MBTI will improve their self-reported sleep quality, as measured by the PSQI.
- MBTI will reduce their self-reported severity of insomnia, as measured by the ISI.
- Improvement in sleep quality and reduction in insomnia severity will result in improvement in self-reported quality of life, as measured by MSQLI scores.
- MBTI will be superior to sleep hygiene counseling in improving sleep quality, reducing insomnia severity, and improving quality of life.

Active Comparator: Mindfulness Intervention
Mindfulness-Based Treatment for Insomnia intervention led by a certified instructor. It is adapted from the Mindfulness-Based Stress Reduction Curriculum developed by the Center for Mindfulness in Medicine, Health Care, and Society at the University of Massachusetts Medical School. It introduces the concept of mindfulness and provides the opportunity to practice it within sessions and during home practice. Participants learn about stress, and explore habitual behavioral, physical, emotional and cognitive patterns, as well as more effective responses to challenges and demands of everyday life. Each class includes mindfulness practice, group discussions, and practices and exercises related to the class topics. Participants receive home assignments with guided meditation and yoga practices.
Behavioral: Mindfulness Intervention
Placebo Comparator: Sleep Hygiene
Control group participants attend a 30-minute group counseling session on sleep hygiene. The session includes a handout from the Centre for Clinical Intervention in Australia that provides 15 sleep hygiene tips.
Behavioral: Sleep Hygiene
Session includes a handout with15 sleep hygiene tips:
- Sleep Quality [ Time Frame: 4 months ]Objective sleep quality will be measured using a Fitbit Charge activity monitor to be worn daily during the 10-week intervention, and daily during a 4-month post-intervention period. For the purpose of assessing the impact of the intervention on objective sleep quality, the first week of Fitbit sleep data collected during the 10-week intervention (i.e., during the week of the mindfulness orientation session) will count as baseline data; the last week of the 10-week intervention will count as post-intervention data; and the last week of the 4-month post-intervention period will be used to assess the sustainability of the intervention. Data from the remaining weeks of the 10-week intervention and 4-month post-intervention periods will be used to examine whether participants experience an upward trend in sleep quality during the course of the study.
- Self-Reported Sleep Quality [ Time Frame: 4 months ]Self-reported sleep quality will be measured using the Pittsburgh Sleep Quality Index (PSQI) at baseline, at the end of the 10-week intervention, and at 4 months post-intervention. The PSQI is a self-rated questionnaire to assess perceived sleep quality and disturbances over a 1-month time interval. This 19-item instrument uses a Likert scale (ranging from 0 to 3) to assess 7 clinically derived domains of sleep: sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these 7 components yields one global score. Clinical and clinimetric properties of the PSQI were assessed over an 18-month period with "good" vs. "poor" sleepers. A global score > 5 yielded a diagnostic sensitivity of 89.6% and specificity of 86.5% (kappa = 0.75, p < 0.001) in distinguishing good vs. poor sleepers.
- Self-Reported Quality of Life [ Time Frame: 4 months ]Self-reported quality of life will be measured at baseline, the end of the 10-week intervention, and 4 months post-intervention using the Multiple Sclerosis Quality of Life Index (MSQLI). The MSQLI includes a set of 10 questionnaires to provide a quality of life measure that is both generic and MS-specific. The questionnaires assess health status, fatigue, pain, sexual satisfaction, bladder control, bowel control, visual impairment, perceived deficits, mental health, and social support. Each individual scale generates a separate score. There is no global composite combining all the scales into a single score. There is good internal consistency reliability for the subscales of the MSQLI, with the lowest alpha being 0.67 (for social functioning on SF-36). Other coefficients range from 0.78 (BWCS) to 0.97 (MSSS). Test-retest reliability on the SF-36 ranges from 0.60 (social functioning) to 0.81 (physical functioning).
- Adverse Events [ Time Frame: 4 months ]Any adverse events, including relapse of MS, experienced by study participants will be noted at the end of the 10-week intervention, and at 4-months post-intervention. In addition, if participants report any adverse events by contacting the research staff and/or study PI at any other time points during the study, these will be noted as well. The study team will address the handling of adverse events on a case-by-case basis.
- Progression of MS [ Time Frame: 4 months ]Progression of MS will be measured by administering the Kurtzke Expanded Disability Status Scale (EDSS) at baseline (clinical screening), the end of the 10-week intervention, and 4 months post-intervention. The EDSS is a method of quantifying the degree of neurologic impairment in MS patients. It quantifies disability in 8 Functional Systems (pyramidal, cerebellar, brainstem, sensory, bowel and bladder, visual, cerebral, and "other"), and allows neurologists or other trained examiners to assign a Functional System Score (FSS) in each FS. Each FSS is an ordinal clinical rating scale ranging from 0 to 5 or 6. The EDSS is an ordinal clinical rating scale ranging from 0 (normal neurologic examination) to 10 (death due to MS) in half-point increments.
- Muscle Spasticity [ Time Frame: 4 months ]Since muscle spasticity is a frequent cause of insomnia in MS patients, the Modified Ashworth Scale (MAS) will be used to characterize the degree of spasticity at baseline (clinical screening), the end of the 10-week intervention and 4 months post-intervention among members of our study population. The MAS is a clinician-administered measure of muscle spasticity in patients with MS or other conditions such as stroke or spinal cord injury. It involves a subjective clinical assessment, without the use of specialized equipment, of muscle resistance to passive range of motion (ROM) about a single joint, while a patient is in a supine position. It uses a nominal scale ranging from 0 (no resistance) to 4 (rigidity), with a 1+ scoring category added to indicate resistance through less than half of the movement.
- Restless Leg [ Time Frame: 4 months ]Since restless leg syndrome can impact insomnia in MS patients, self-reported restless legs syndrome severity will be measured using the International Restless Legs Scale (IRLS) at baseline, at the end of the 10-week intervention, and 4 months post-intervention to characterize the extent of this condition in our study population. The IRLS was developed by the International RLS Study Group to measure perceived severity of restless legs syndrome in the past week prior to administration. It includes 10 questions addressing respondents' perceptions of RLS-related discomfort, need to move around, relief from moving around, severity of sleep disturbance and tiredness from RLS symptoms, severity of RLS as a whole, frequency and severity of symptoms, severity of impact on daily living, and severity of mood disturbance. Response options are based on a 5-point scale ranging from 0 to 4, with 4 being very severe.
- Medication and Supplements [ Time Frame: 4 months ]A list of medications and/or supplements used will be collected at baseline, the end of the 10-week intervention, and 4-months post-intervention to track changes in use of medication or supplements during the course of the study.
