Twenty percent of individuals experience chronic pain worldwide posing significant challenges to those living with it. Pain research is crucial for developing and characterizing effective strategies to reduce the burden of chronic pain. Traditional research approaches often yield homogeneous study samples that poorly generalize and have unknown applicability across diverse patient populations. The Pain Relief with Online Groups that Empower Skills-based Symptom Reduction (PROGRESS) study aims to address disparities in pain research engagement and patient outcomes through the intentional inclusion of people with varied backgrounds and experiences of pain, and through a multilevel design informed by diverse stakeholder recommendations. The composition of three advisory boards (Patient Engagement and Diversity Board, Local Patient Advisory Board, and the National Patient Advisory Panel) prioritized diversity in patient/expert advisor background, geographic location, race, and ethnicity. Our engagement approach aligns with the Foundational Expectations for Partnerships in Research by Patient-Centered Outcomes Research Institute (PCORI), which emphasizes diverse representation, early and ongoing engagement, dedicated funds for advisor compensation, collaborative decision making, meaningful participation, and continuous assessment. The first 24 months of study advisor engagement has yielded multiple recruitment strategies resulting in a study population enriched with a breadth of identities within PROGRESS (e.g., inclusive patient-facing materials). Lessons learned underscore the importance of investing time in building patient and stakeholder relationships, trust, and embracing diverse viewpoints amongst the study team. PROGRESS demonstrates the potential of diverse patient-centered engagement to support evidence-based outcomes and practices that are more inclusive, equitable, and representative of the broader population. PERSPECTIVE: The PROGRESS study demonstrates how diverse patient engagement and inclusive advisory boards enhance research outcomes. By aligning with PCORI standards and employing innovative recruitment strategies, it highlights the vital role of stakeholder relationships and diverse perspectives. Key lessons learned emphasize adaptive strategies and continuous feedback for advancing equitable pain research., Competing Interests: Declaration of Competing Interest Empowered Relief® is owned and copyrighted by Stanford University.

Current knowledge about mechanisms and interventions for pain has largely been derived from samples that are healthier, wealthier, younger, and more likely to be White than the general population. Failure to conduct inclusive pain research not only restricts generalizability and application of findings, but also hampers the discovery of mechanisms and the development of measures and interventions that are valid across population subgroups. Most of all, inclusive practices are critical to ensure that underrepresented groups derive equitable benefit from pain research. Here, we provide guidance for the pain research community on how to adopt inclusive research practices. We define "inclusion" to encompass a range of identities and characteristics, including racialized group/ethnicity, disability status, gender identity, sexual orientation, and age. We first describe principles relevant to promoting inclusion in pain research, including attention to: 1) stakeholder engagement; 2) structural factors underlying inequities; 3) the limitations of "disparity" research; 4) intersectionality; and 5) universal design. Next, we provide checklists with practical strategies for making studies more inclusive at each stage of the research process. We conclude by calling for system-level changes to ensure that the future of pain research is socially just, scientifically productive, and responsive to the needs of all people. PERSPECTIVE: This paper offers guidance on promoting inclusion of underrepresented groups in pain research. We describe principles relevant to conducting more inclusive research; eg, attention to stakeholder engagement, structural factors, and universal design. We provide checklists with practical strategies for inclusion at each stage of the research process., (Copyright © 2021 United States Association for the Study of Pain, Inc.

Racial equity is imperative to the future and integrity of scientific inquiry. In 2020, citizens of the United States (and globally) witnessed one of the most vile and egregious experiences of police brutality and systemic racism in recent history, the public execution of a Black American man. While some may isolate this and other similar events from influencing the scientific endeavors of pain researchers, events such as this can have a direct impact on the study, lived experience, and expression of pain in Black Americans. To truly understand the biopsychosocial effects of inequality and injustice on pain disparities, we must consider the unintended consequences that our current research approaches have in limiting the reliability and validity of scientific discovery. As we reflect on our current research practices in an effort to improve pain science, this perspective article discusses ways to initiate positive change in order to advance the science of pain in more equitable ways, not just for Black Americans, but for all individuals that identify as part of an underrepresented group. PERSPECTIVE: Elimination of inequities in pain care and research requires the identification, naming, and mitigation of systemic discriminatory and biased practices that limit our understanding of pain disparities. Now is the time to divest from traditional research methods and invest in equitable and innovative approaches to support pain researchers in advancing the science and improving the lives of people with pain., (Copyright © 2021 United States Association for the Study of Pain, Inc.
