Multiple Sclerosis, Relapsing-Remitting
Conditions
Brief summary
The primary objective of the study is to understand what the added value of natalizumab (Tysabri®) treatment is from a participant's perspective at a given time, based on a one-shot survey. The secondary objectives of the study also aim to characterize the participant's decision-making process to get the treatment; the burden of treatment, characterization of the study population, assessment of the quality of life (QoL), and fatigue dimension.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants who Perceived the Treatment Added Value of Natalizumab Assessed by Likert's Scale | Day 1 | A Likert scale is a rating scale used to measure opinions, attitudes, or behaviors. This 7-pointer scale consists of a statement or a question, followed by a series of five or seven answer statements. Respondents choose the option that best corresponds with how they feel about the statement or question. The options include: strongly agree, agree, somewhat agree, neutral, somewhat disagree, disagree to strongly disagree. |

| Number of Participants With Perceived Decision-making Process Assessed by Likert's Scale | Day 1 | A Likert scale is a rating scale used to measure opinions, attitudes, or behaviors. This 7-pointer scale consists of a statement or a question, followed by a series of five or seven answer statements.

The options include: strongly agree, agree, somewhat agree, neutral, somewhat disagree, disagree to strongly disagree. |
| Mean Multiple Sclerosis International Quality of Life Questionnaire (MusiQol) Score | Day 1 | The MusiQoL is a self-administered questionnaire consisting of 31 items describing nine dimensions of health-related QoL: activities of daily living, psychological wellbeing, symptoms, relationship with friends, relationship with family, sentimental and sexual life, coping rejection, relationship with healthcare system. All items are scored based on frequency/extent of an event on a five-point scale ranging from 1 (never/not at all) to 5 (always/very much). Total score is obtained by linearly transforming and standardizing on a 0-100 scale. Higher scores indicate a better QOL. |
| Mean Fatigue Severity Scale (FSS) Score | Day 1 | FSS is designed to differentiate fatigue from clinical depression. FSS is a 9-item questionnaire that requires the participant to rate their own level of fatigue on a scale of 1 (strongly disagree) to 7 (strongly agree). The total score ranges from 9 to 63. A higher total score indicates greater fatigue severity and impairment. |
