Mindfulness-based stress reduction is a formalized, experiential, 8-week stress-management program. Participants attend weekly two-hour classes and a half-day retreat during which they learn mindfulness meditation, breath work, yoga postures, self-reflection and awareness.

The MS Education Control program is matched to MBSR for time and attention yet has no overlap with intervention content. Each two-hour class uses a pamphlet published by the National MS Society to present information about a different MS topic such as Fatigue; Bowel and Bladder Problems; Diet; Spasticity; and Nutritional Supplementation: Vitamins, Minerals, and Herbs.

Feasible recruitment is defined as the ability to recruit and enroll 60 participants with multiple sclerosis (MS) over a ten-month time frame. Recruitment rate will be calculated as the proportion of eligible patients who provided informed consent per month.

Adherence will be tracked with a sign-in/sign out sheet at each class and with daily homework logs. Attendance will be calculated by a sign in/sign out sheet, being present for at least 75% of a class will count as attended. Homework will be tabulated as both a frequency count (number of days homework was completed) and amount (total number of minutes completed). Participants who are present for at least 5 of the classes, including the final class, and complete at least 70% of homework will be recorded as 'adherent'.

Adoption is defined as the ability of participants to take part in activities such as yoga poses and meditative exercises. Qualitative outcomes include a brief, semi-structured focus group conducted at the beginning of the MBSR classes during weeks five and eight. Focus groups will address successes and any challenges participants may be experiencing. Focus groups will be audio recorded and transcribed verbatim for qualitative analysis.

A feasible completion rate is defined as complete follow-up in at least 70% of enrolled subjects at 12-months post-intervention. Completion indicates acceptability of a long-term trial and will inform future study designs.
