Roles in the Discussion: An Analysis of Social Support in an Online Forum for People with Dementia

Social computing provides a variety of challenges and opportunities for people who are aging. In particular, older adults sometimes engage in online communities designated for people with dementia to understand their diagnosis and gain support. In this work, we analyzed 186 posts from a seven-year period on a forum for persons with dementia to understand 1) who interacts in this forum and 2) what kinds of activities interactants engage in. Our analyses indicate that, in addition to people with dementia, a variety of dementia-related stakeholders participate in this forum. Our results also suggest that seeking and offering social support are key activities for all forum users, not just those with dementia for whom the forum was designated. Given these findings, we offer design implications for online spaces for vulnerable communities, with a focus on design that allows for external stakeholder participation while still maintaining the privacy and safety of vulnerable members of the community.
