The purpose of this study was to explore the social experiences of older adults with multiple sclerosis (MS) in order to recognize the changes in social experience and social needs that may occur with aging with a chronic illness. Analysis of qualitative data from an exploratory study utilizing a phenomenological approach with 27 older adults with MS, aged 55 - 81. In-depth interviews revealed that the social experience was influenced by groups of factors including the person's social needs, experience of MS, values and expectations, characteristics of the social support system, the response of the support providers, and the accessibility of the social environment. The participants discussed concerns about the future adequacy of support. A process of negotiation was also described and was seen as an opportunity to change the social experience and social support received. This study provides an insider's view of the social changes that older adults living with MS experience. This study also identifies barriers to the acquisition of support and addresses the importance of appropriately responding to the changing needs of this population.
