Mindfulness Meditation in Treating Insomnia in Multiple Sclerosis

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.
