Diet and multiple sclerosis - development and mixed methods feasibility testing of a comprehensive nutritional...

Persons with multiple sclerosis (pwMS) are often confused by contradictory dietary advice. The purpose of this research was to explore the information needs and design a comprehensive, evidence-based nutritional information resource on diet and MS (NUTRIMS).

A mixed-methods design with three sequential phases was adopted: (1) Needs assessment and development: Two focus groups with pwMS to explore experiences, information needs and preferred support around diet. Development of a draft NUTRIMS, (2) Feasibility Step 1: Feedback on the draft NUTRIMS from stakeholders and (3) Feasibility Step 2: Online survey among pwMS to explore content quality and acceptability.

Two focus groups with a total of 12 pwMS showed that MS-specific evidence on food groups/ingredients, nutrients and special diets were of most interest. The draft NUTRIMS was refined through feedback from 13 stakeholders. The pre-final NUTRIMS consisted of 81 pages including scientific references on each topic, 16 illustrations and a glossary of terms. 85 pwMS participated in the online survey and reported an intensive use and high satisfaction with the information resource, which was perceived as comprehensible, highly credible and useful for making decisions on dietary change.

A collaborative research approach led to a well-accepted nutrition information resource.
