Adapting the model of consumer behavior to the design of an online health research recruitment tool.

Introduction: UMHealthResearch is the University of Michigan's digital health research recruitment platform. It allows health researchers to connect efficiently with potentially eligible volunteers.

Methods: In 2013, the UMHealthResearch team strategically adapted a consumer behavior model, the buying funnel, to create the Digital Health Research Participation Funnel. The Digital Health Research Participation Funnel was then used to design a more active way for potential participants to volunteer for research studies through UMHealthResearch.

Results: In the 5 years before the redesign (2007-2012), an average of 1844 new accounts were created every year, whereas in the completed years after the redesign (2013-2016) the annual average improved to 3906, an increase of 111%.

Conclusion: Although a randomized design was not possible in this instance, these preintervention and postintervention data suggest that the focus on user experience is an effective strategy for improving web-based research recruitment platforms.
