Patient information sheet


Multiple sclerosis


The online questionnaire consists of questions about patient demographics, clinical characteristics, quality of life measures (using the multiple sclerosis quality of life (MSQOL)-54), health state (using the EuroQol 5 Dimensions (EQ-5D-5L)). The questionnaire will be made available in five languages (Dutch, French, English, German and Italian). Official translations of the MSQOL-54 and EQ-5D-5L will be used and the remaining questions will be translated. Patients that choose to participate in the questionnaire will only have to fill it out once.
