## Abstract

Health disparities are costly and preventable differences in disease progression that disproportionately affect minority communities such as African Americans. Practices to reduce health disparities can be rooted in prevention, particularly through screening tools. Family Health History tools are preventative screening mechanisms meant to explore family history to better understand how an individual’s health can potentially be predicted or impacted. These tools are underutilized in the African American community. Contributions to this underutilization include a lack of cultural tailoring in the tools, a lack of health literacy in community members, and a lack of effective health communication. The Family Health History Study will create a culturally appropriate Family Health History toolkit to increase family health history utilization and ultimately decrease health disparities.

The proposed sample will be composed of 195 African American adults ages 18 + who live in Genesee County, Michigan. The study consists of two phases: the development phase and the randomized pilot study phase. The goal of the development phase (n = 95) is to explore how Family Health History toolkits can be modified to better serve the African American community using a community based participatory research approach and to create a culturally tailored family health history toolkit. In the pilot study phase, 100 participants will be randomized to the culturally tailored toolkit or the current standard Family Health History toolkit. Outcomes will include feasibility and acceptability of the intervention.

This study will result in a culturally appropriate Family Health History tool that is co-developed with community members that can be utilized by African American adults to better understand their family health histories.
