-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage adherence of subjects on Rebif, using the Morisky Green Levine Medication Adherence Scale (MGLS) Score | MGLS is a four item self-reported questionnaire to assess medication adherence. It consists of four questions/items evaluating drug intake habits in subjects on chronic therapies with a scoring scheme of Yes = 1 (no adherence) and No = 0 (adherence). The items are summed to give an overall score, which ranges from 0 to 4 where high adherence=0, medium adherence=1-2 or low adherence=3-4. | Month 24 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of subjects on Rebif who discontinued the treatment |  | up to 24 months | 
| Time to treatment discontinuation |  | up to 24 months | 
| Reason for treatment discontinuation | The reason for treatment discontinuation will includes: adverse event, lost to follow-up, lack of efficacy, protocol noncompliance, progressive disease, withdrew consent, death, frequency, unrealistic expectations, other | up to 24 months | 
| Percentage of relapse-free subjects |  | Month 24 | 
| Percentage of subjects with expanded disability status scale (EDSS) progression | EDSS is used for multiple sclerosis disability assessment. It is a 10 point scale, where 0 indicates normal motor skills, and 10 indicates patient's death. EDSS progression is defined as one point increase sustained for at least three months. | Month 24 | 
| Number of subjects with suspected adverse drug reactions (ADRs) related to Rebif treatment and concomitant therapy over the 24 months of the study |  | Up to 24 months | 
| Percentage of relapse-free subjects based on MGLS Score |  | Up to 24 month |
