Investigating Opportunities for Crowdsourcing in Church-Based Health Interventions: A Participatory Design Study.

Churches play a major role in providing social support to address health inequities within Black communities, in part by connecting members to key organizations and services. While public health has a history of disseminating interventions in faith communities, little work has explored the use of crowdsourcing to tailor interventions to the unique culture of each church community. Following Community Based Participatory Research principles, we partnered with two predominantly Black churches, and report on a series of three participatory design sessions with nine participants. We developed a novel storyboarding method to explore how crowdsourcing could promote health in these faith-based communities. Our findings characterize existing supports within the church community, and how church social structures impact member access to these supports. We further identify motivations to engage with a church-situated health application, and how these motivations translate to crowdsourcing tasks. Finally, we discuss considerations for public health crowdsourcing tasks.
