The Radical Welcome Engagement Restoration Model and Assessment Tool for Community-Engaged Partnerships.

People experiencing addiction, houselessness, or who have a history of incarceration have worse health outcomes compared with the general population. This is due, in part, to practices and policies of historically White institutions that exclude the voices, perspectives, and contributions of communities of color in leadership, socio-economic development, and decision-making that matters for their wellbeing. Community-based participatory research (CBPR) approaches hold promise for addressing health inequities. However, full engagement of people harmed by systemic injustices in CBPR partnerships is challenging due to inequities in power and access to resources. We describe how an Allentown-based CBPR partnership-the Health Equity Activation Research Team of clinicians, researchers, and persons with histories of incarceration, addiction, and houselessness-uses the Radical Welcome Engagement Restoration Model (RWERM) to facilitate full engagement by all partners. Data were collected through participatory ethnography, focus groups, and individual interviews. Analyses were performed using deductive coding in a series of iterative meaning-making processes that involved all partners. Findings highlighted six defining phases of the radical welcome framework: (a) passionate invitation, (b) radical welcome, (c) authentic sense of belonging, (d) co-creation of roles, (e) prioritization of issues, and (f) individual and collective action. A guide to assessing progression across these phases, as well as a 32-item radical welcome instrument to help CBPR partners anticipate and overcome challenges to engagement are introduced and discussed.
