How are cognitive impairment, fatigue and signs of depression related to participation in daily life among persons with multiple sclerosis?

Purpose: Factors that impact participation are of scientific and clinical importance. Participation in everyday activities among persons with multiple sclerosis (MS) can be compromised by various factors however the combined contribution of these factors to participation has not been explored. The aim of this study was to describe the relationship between cognitive impairment, physical disability and signs of depression and participation in daily life among persons with MS. Methods: Data from 200 participants were collected in an observational, prospective study. The majority was female, had mild physical disability, and an average age of 48.7. The impact of independent variables, including demographic and disease related data, levels of cognitive impairment, signs of depression and fatigue, on participation was investigated using path analysis. Results: Cognitive impairment was associated with restricted participation in domestic, leisure and outdoor domains. Restrictions in leisure and outdoor activities, but not domestic activities were related to signs of depression. Cognitive impairment was associated with the level of education and the level of physical disability. Conclusions: Increasing participation is an important outcome of rehabilitation. The results of this study suggest a multifactorial approach to intervention that considers physical, mental and emotional component to maximize participation among persons with MS.
