The purpose of this study is to assess the ability of the home-based intervention, HOBSCOTCH-MS to improve the quality of life and cognitive function in Service Members, Veterans and civilians who have multiple sclerosis with cognitive and memory problems (MS participants). This study will also assess the ability of the HOBSCOTCH-MS program to improve quality of life in caregivers of patients with multiple sclerosis and to reduce caregiver burden. Enrolling with a Caregiver is optional for MS participants. Investigators will compare two groups of MS participants and their Caregiver (enrolling with a Caregiver is optional): one who receives HOBSCOTCH-MS immediately (Group 1) and another group that will receive HOBSCOTCH-MS (Group 2) after a 3-month waiting period. Participants will be in the study for about 6 months total. HOBSCOTCH-MS involves 45 to 60 minute one on one virtual sessions with a certified Cognitive Coach including a pre program session and 8 weekly sessions thereafter. Participants will learn about problem solving therapy and mindfulness or relaxation training. MS participants are asked to do short homework assignments and both MS and Caregiver participants are asked to keep a brief daily diary on a smart phone app. All participants complete study questionnaires or surveys at enrollment, 3 months later and at 6 months (at the end of the study). After completing the intervention, MS Participants and their Caregivers may also participate in an optional one-time Key Informant Interview for qualitative analysis in an effort to further adapt and improve the HOBSCOTCH-MS in the future.
