Multiple sclerosis (MS) is the leading cause of disability among middle-aged adults with recent estimates of nearly 1 million adults living with MS in the United States. Multiple sclerosis affects women anywhere from two to three times as often as men, with an age of diagnosis ranging from 20 to 50 years of age and a mean age of onset of 33 years of age. A host of physical, cognitive, and behavioral changes are common following the onset of this most common non-traumatic neurological disorder of middle adulthood, which greatly impacts quality of life (QOL), well-being, and everyday functioning and participation. Moreover, given that individuals are typically diagnosed with MS in the prime of their lives many are making important life decisions regarding work, family, etc. that are often hindered by their diagnosis. In fact, it has been found that men and women with MS aged 25-44, an age at which important early life decisions are often made, experienced more depression than their age-matched, healthy counterparts. Again, the course of the disease is variable and unpredictable with no known cure, which can lead to great uncertainty and difficulty in adjusting to a chronic and often, debilitating disease. The overarching aim of the proposed investigation is to adapt the Reinventing Yourself intervention for use with MS and examine the feasibility and efficacy in increasing MS-specific and general self-efficacy and resilience, enhancing psychological well-being, fostering new ways of perceiving and managing one's illness in more proactive and positive ways, and improving participation in the community. To achieve this, the investigation has the following specific aims: Specific Aim 1: Conduct a focus group with individuals with MS to identify unique needs of individuals with MS with regard to MS symptoms, barriers to well-being, QOL, and participation, and the role that person-specific factors (e.g., self-efficacy, resilience) and other psychological and social factors have contributed to success (or failure) in managing one's illness and living well. Specific Aim 2: With the knowledge gained from Aim 1, modify the Reinventing Yourself intervention with the specific needs of MS, while maintaining the integrity and common principles of the Reinventing Yourself intervention. Specific Aim 3: Conduct a RCT among individuals with MS to determine the feasibility and efficacy of the Reinventing Yourself with MS intervention.

Arms

Experimental: Group Intervention

Participants will attend six weekly two-hour facilitator-led sessions that include didactic presentations of eight core skills and related experiential exercises with extensive group discussion. These skills are presented in sequence over the course of the intervention so that participants can gain mastery of introductory concepts before undertaking those that are both more difficult and complex. The culmination of developing these skills and participation in a peer group will assist individuals in increasing self-efficacy and overall QOL, well-being and participation. Participants will complete follow-up assessment at 18- and 30-weeks post-intervention.

Placebo Comparator: Placebo

Participants will receive no intervention throughout the course of the study; however, the participants will be tested at 18- and 30-weeks participation in the study.
