What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Compliance to therapy (%) | Compliance (%) = ((expected # of treatment days during observation period - missed # of treatment days during observation period)/(expected # of treatment days during observation period))*100 | 12 months | 
| Persistence of therapy (Yes or No) | Persistence is defined as patients continuing (persisting) their medication (regardless of the frequency of intake) | 12 months | 
| Overall adherence to therapy (Yes or No) | Patients will be defined as being adherent to therapy if they fulfill the following criteria: a. They have been at least 80% compliant, i.e. injected ≥80% of the expected Betaferon dosages and b. They have not dropped out of the study prior to the time of evaluation (i.e. they did not stop Betaferon treatment for any reason including switching to another medication prior to the time of evaluation). | 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Satisfaction with the BETACONNECT autoinjector, recorded by the patient questionnaire |  | Up to 24 months | 
| Adherence to Betaferon treatment is associated with: depression, health related quality of life, coping mechanisms, self-management mechanisms, social support, fatigue, and cognition. (Yes or No) |  | Up to 24 months | 
| Adherence to Betaferon treatment is associated with number of relapses (Yes or No) |  | 12 months, 24 months | 
| Adherence to Betaferon treatment is associated with EDSS change (Yes or No) | EDSS (Expanded Disability Status Scale) | 12 months, 24 months | 
| Adherence to Betaferon treatment is associated with utilities of treatment, recorded by the EQ-5D quality of life questionnaire (Yes or No) |  | Up to 24 months |
