Portuguese Observational Survey to Assess Drug Adherence in Patients With Multiple Sclerosis After Conversion to Betaferon by Using Elements of the BetaPlus Program - Nurse Support, Auto-injectors

Study Overview
=================
Brief Summary
-----------------
This is an observational survey to assess the factors that influence adherence to Betaferon therapy in multiple sclerosis patients using elements of the BetaPlus support program, including the nurse support and auto-injectors.
