Mean scores and standard errors for the measures of fatigue, depression, pain, and perceived cognitive complaints based on mild, moderate, and severe clusters of symptoms identified in the cluster analysis with the sample of individuals with MS (n=133). MSIS-29=Multiple Sclerosis Impact Scale-29; Physical=physical subscale of Multiple Sclerosis Impact Scale-29; Psychological=psychological subscale of Multiple Sclerosis Impact Scale-29. Lower MSIS-29 scores represent higher QOL.
