Change From Baseline in Multiple Sclerosis International Quality of Life (MusiQoL) Scores to Week 8
The MusiQoL is a validated 31-item questionnaire describing 9 dimensions named according to its constitutive items:activities of daily living (8 items);psychological well-being (4 items);symptoms (3 items);friends relationships (4 items);family relationships (3 items);satisfaction with health care (RHCS 3 items);sentimental and sexual life (2 items);coping (2 items);and rejection (2 items). Each of the questions was answered using a 6-point Likert scale, defined as 1-Never/Not at all, 2-Rarely/A little, 3-Sometimes/Somewhat, 4-Often/A lot, 5-Always/Very much and 6-Not applicable. The scores of each dimension were obtained by computing mean of the item scores of dimension with negatively worded item scores reversed so that higher scores indicated higher health-related QoL. All 9 dimension scores were linearly transformed to a 0-100 scale,where higher score=higher health-related QoL. Global index score was computed as mean of the 9 dimension scores (range 0-100;higher score=higher QoL).
Time frame: Baseline, up to Week 8
