Reduction of cancer-related disparities requires strategies that link medically underserved communities to preventive care. In this community-based participatory research project, a public library system brought together stakeholders to plan and undertake programs to address cancer screening and risk behavior. This study was implemented over 48 months in 20 large urban neighborhoods, selected to reach diverse communities disconnected from care. In each neighborhood, Cancer Action Councils were organized to conduct a comprehensive dynamic trial, an iterative process of program planning, implementation and evaluation. This process was phased into neighborhoods in random, stepped-wedge sequence. Population-level outcomes included self-reported screening adherence and smoking cessation, based on street intercept interviews. Event-history regressions (n = 9374) demonstrated that adherence outcomes were associated with program implementation, as were mediators such as awareness of screening programs and cancer information seeking. Findings varied by ethnicity, and were strongest among respondents born outside the U.S. or least engaged in care. This intervention impacted health behavior in diverse, underserved and vulnerable neighborhoods. It has been sustained as a routine library system program for several years after conclusion of grant support. In sum, participatory research with the public library system offers a flexible, scalable approach to reduce cancer health disparities., (© Society for Community Research and Action 2017.)

Background: Cancer is the leading cause of preventable death in the Bronx, New York. Service providers in this mental health provider shortage area identified untreated mental illness as an important barrier to participation in cancer screening, a finding that supports existing literature. The Mental Health and Cancer (MHC) Connection partnership formed to investigate and address this issue., Objectives: We sought to use an ecological framework to examine barriers and facilitators to obtaining mental health services in the Bronx, and to explore how lack of access to mental healthcare affects cancer screening., Methods: In this community-based participatory research (CBPR)-driven pilot study, semistructured, qualitative interviews based on an ecological framework were conducted with 37 Bronx-based service providers representing a range of professional perspectives. Data were analyzed using thematic content analysis and techniques from grounded theory., Results: Similar barriers and facilitators were reported for mental healthcare and cancer screening utilization across ecological levels. Providers emphasized the impact of urban poverty-related stressors on the mental health of their clients, and affirmed that mental health issues were a deterrent for cancer screening. They also recognized their own inability to connect clients effectively to cancer screening services, and rarely saw this as part of their present role., Conclusions: Findings highlight how unmet mental health needs can affect cancer screening in impoverished urban contexts. Participants recommended improving linkages across healthcare and social service providers to address mental health and cancer screening needs simultaneously. Study results are being used to plan a collaborative intervention in the Bronx through the MHC Connection partnership.

Dissemination efforts must optimize interventions for new settings and populations. As such, dissemination research should incorporate principles of quality improvement. Comprehensive Dynamic Trial (CDT) designs examine how information gained during dissemination may be used to modify interventions and improve performance. Although CDT may offer distinct advantages over static designs, organizing the many necessary roles and activities is a significant challenge. In this article, we discuss use of the Interactive Systems Framework for Dissemination and Implementation to systematically implement a CDT. Specifically, we describe "Bronx ACCESS", a program designed to disseminate evidence-based strategies to promote adherence to mammography guidelines. In Bronx ACCESS, the Intervention Delivery System will elicit information needed to adapt strategies to specific settings and circumstances. The Intervention Synthesis and Translation System will use this information to test changes to strategies through "embedded experiments". The Intervention Support System will build local capacities found to be necessary for intervention institutionalization. Simulation modeling will be used to integrate findings across systems. Results will inform on-going policy debate about interventions needed to promote population-level screening. More generally, this project is intended to advance understanding of research paradigms necessary to study dissemination.

In unstable economic environments, CBPR partnerships in underserved communities may face unanticipated obstacles that threaten success and sustainability. This report describes challenges experienced by HealthLink, a CBPR partnership to address cancer disparities in Queens, N.Y., and how HealthLink adapted. Recommendations for designing CBPR partnerships to overcome unexpected challenges are provided.
