Policy stakeholders’ perspectives and use of data, research evidence, and misinformation in three counties in California, USA during the COVID-19 pandemic, 2020–2022. Preventive Medicine Reports, 54, Article 103098. https://doi.org/10.1016/j.pmedr.2025.103098 (Original work published 2025)

Objective

This study investigates how local policy stakeholders viewed and used research evidence, data, and (mis)information in county policy discussions during the COVID-19 pandemic.

Method

We employed document and exploratory content analysis methods to examine Board of Supervisor materials (N = 534 policy documents) from general and special/emergency meetings (March 2020 – December 2022). We purposefully selected three jurisdictions from California, USA with varying socio-demographic, political, and health care characteristics as case studies.

Results

Many residents who commented during local policy discussions contested the: 1) validity of health data provided (i.e., mortality rates), and 2) efficacy of proposed preventive measures like mask wearing and vaccine receipt. While government officials and healthcare personnel referenced research evidence and data as justification for these measures, several stakeholders expressed skepticism about the information presented in all three counties. Perceptions of misinformation included statements by residents that questioned the COVID-19 information provided by government officials or reflected a belief that federal and state government agencies (e.g., Centers for Disease Control and Prevention, CDC) were sources of misinformation. An emergent finding was that many residents voiced uncertainty and requested more information about local pandemic conditions and policy mitigation strategies.

Conclusions

Results reveal a distrust of public health and government officials and data/information shared in local policymaking debates during the COVID-19 pandemic. Local health departments may benefit from investing in efforts to increase their credibility as trusted sources of health information among community members. Local government agencies should develop transparent health promotion campaigns to identify and dispel misinformation.

Community-Led Solutions: How Local Organizing Committees Drive Change for Housing and Health Equity in California’s Central Valley. Journal of Participatory Research Methods, 5(2). https://doi.org/10.35844/001c.120257 (Original work published 2024)

In this research brief, we describe how the HOPe Lab (UC Merced), Faith in the Valley (Fresno), and Cultiva Central Valley (Merced) are collaborating to address housing-related disparities within California’s culturally diverse Central Valley. Focused on the transformative role of Local Organizing Committees (LOCs), our research employs an anti-racist research praxis to actively engage residents, enhance leadership capacity, and foster communication between residents and elected officials. Drawing on several theory-of-change statements and the practical insights gained from “field experts” carrying out ongoing initiatives, this report explores the positive impact of LOCs on meaningful community involvement, empowerment, engagement, accountability, and policy changes.

Progress in Community Health Partnerships: Research, Education, and Action, 18(1), 1-9. (Original work published 2024)

Objective: We sought to examine the experiences of community partners in a community–academic partnership to promote COVID-19 testing in two majority Latino communities.

Methods: We conducted semistructured, in-depth interviews in English and Spanish with community-based organization leaders and community health workers/promotoras (n = 10) from June to July 2021. Interviews focused on identifying partner roles in planning and testing implementation and evaluating communication among partners. Interviews were transcribed and analyzed in ATLAS.ti version 8.4.5. Analyses involved deductive and inductive approaches to identify key themes.

Results: Participants described both strengths and challenges to the collaborative approach within each of three core themes: building relationships in the time of COVID-19; uplifting existing community leadership; and commitment of the academic partners and community-based organizations to conduct partnership activities in Spanish.

Conclusion: Community–academic partnerships that invest in strong relationships, community leadership, and a commitment to the community's preferred language offer a promising approach to addressing COVID-19 testing barriers. Findings provide direction for future research on how community members and academic partners can come together to inform strategies to continue addressing the COVID-19 pandemic.

Mixed Methods for Research on Support Networks of People Experiencing Chronic Illness and Social Marginalization. Qualitative Health Research, 1-14. https://doi.org/10.1177/10497323241235031 (Original work published 2024)

Substantial research has focused on how social networks help individuals navigate the illness experience. Sociologists have begun to theorize beyond the binary of strong and weak social network ties (e.g., compartmental, elastic, and disposable ties), citing the social, economic, and health conditions that shape their formation. However, limited research has employed mixed social network methods, which we argue is especially critical for examining the “non-traditional” social support networks of marginalized individuals. We employ quantitative social network methods (i.e., the egocentric network approach) in addition to in-depth interviews and observations, with a novel tool for capturing network data about social groups, to surface these kinds of supportive relationships. Using the case of “nameless ties”—non-kin, non-provider ties who were unidentifiable by given name or were grouped by context or activity rather than individually distinguished—we show how mixed social network methods can illuminate supporters who are commonly overlooked when only using traditional social network analysis. We conclude with a proposal for mixed methods and group alter approaches to successfully observe liminal support ties that is ideal for research about individuals experiencing chronic disability, poverty, housing insecurity, and other forms of social marginalization.

Social support in the urban safety net: Assessing tie activation among individuals with complex care needs. Journal of Social and Personal Relationships, 1-24. https://doi.org/10.1177/02654075241229748 (Original work published 2024)

Activating social ties is a critical mechanism for satisfying individuals’ social, emotional, and material needs. Researchers have offered a number of hypotheses around tie activation about when and why particular supporters step in to help, ranging from strategic activation via functional specificity to opportunistic mobilization. To date, few studies have examined multiple tie activation strategies in tandem. This project focuses on people facing complex, compounding health and social problems, who may have to rely on multiple forms of activation to get their support needs met. We draw on a sample of 92 participants who are affiliated with one of two Care Management programs in the Western United States. Using name generators in a survey, we elicit participants’ social networks and find they utilize a number of methods to secure critical support needs, including calling on kin ties to borrow money and help with daily tasks, relying on strong and proximal ties for almost all types of support, and using functional specificity for health support. We then draw on qualitative interviews to gain a deeper understanding of the ways alters provide support and why egos elicit support from some alters and not others. Future research should continue assessing this population’s social networks with the aim of leveraging social support to help manage chronic conditions, provide access to resources, and increase their sense of belonging.

Dubbin, L., & Yen, I. H. (2023). Renovating space to age in place: Experiences of elderly residents living through public housing renovations and reflections from affordable housing developers. Journal of Aging and Environment. https://doi.org/10.1080/26892618.2023.2280961 (Original work published 2023)

In this article, we explore the experiences of older adults living in public housing undergoing renovations and its associated impacts on their perceived sense of well-being. We also consider the ways in which affordable housing developers contemplate residents’ health and wellness into renovation plans and processes. Following the conventions of hermeneutic analysis, we conducted open-ended in-depth interviews with older adults living in public housing undergoing renovations (n = 21) and representatives of a variety of affordable housing developers (n = 12). Our analysis demonstrates that residents had strong attachments to their individual living spaces prior to renovations and were fiercely protective of them. Renovations created a sense of unease among older residents as the familiar features of their homes were altered. The processes and the outcomes of renovations and new management strategies raised fears that their lived environments were becoming institutionalized. Developers acknowledged that a tension exists between residents’ desires for personalized private space, and their responsibilities as landlords to prioritize the physical safety of residents and the fiduciary obligations to maintain building longevity.

Education and Urban Society, 56(6), 655-681. https://doi.org/10.1177/00131245231193406 (Original work published 2023)

As part of a larger project focused on the intersection of educational and health trajectories over the life course, we use in-depth interviews with 28 adults who experienced multiple non-promotional school changes during the course of their K-12 schooling in three U.S. urban centers to advance understanding of frequent student mobility. Prior research focuses predominantly on isolating the impact of student mobility while saying little about processes through which mobility influences educational trajectories in particular contexts. Frequent student mobility was intertwined with adverse childhood experiences and access to coping resources, and these forces shaped participants’ trajectories in patterned ways. Supporting frequently mobile students, almost a third of school-age children in the United States, will require greater attention to the reasons for, processes of, and contexts of student mobility.

The study objective was to investigate the effects of childhood residential mobility on older adult physical and mental health. In REasons for Geographic and Racial Differences in Stroke (REGARDS) Study, we used linear regression models to investigate if number of moves during childhood predicted mental and physical health (SF-12 MCS, PCS), adjusting for demographic covariates, childhood socioeconomic status (SES), childhood social support, and adverse childhood experiences (ACEs). We investigated interaction by age, race, childhood SES, and ACEs. People who moved more during childhood had poorer MCS scores, β = −0.10, SE = 0.05, p = 0.03, and poorer PCS scores, β = −0.25, SE = 0.06, p < 0.0001. Effects of moves on PCS were worse for Black people compared to White people (p = 0.06), those with low childhood SES compared to high childhood SES (p = 0.02), and high ACEs compared to low ACEs (p = 0.01). As family instability accompanying residential mobility, family poverty, and adversity disproportionately affect health, Black people may be especially disadvantaged.

As medicine integrates social and structural determinants into health care, some health workers redefine housing as medical treatment. This article discusses how health workers in two U.S. urban safety-net hospitals worked with patients without stable housing. We observed ethnographically how health workers helped patients seek housing in a sharply stratified housing economy. Analyzing in-depth interviews and observations, we show how health workers: (1) understood housing as health care and navigated limits of individual care in a structurally produced housing crisis; and (2) developed and enacted practices of biomedical and sociopolitical stabilization, including eligibilizing and data-tracking work. We discuss how health workers bridged individually focused techniques of clinical care with structural critiques of stratified housing economies despite contradictions in this approach. Finally, we analyze the implications of providers' extension of medical stabilization into social, economic, and political realms, even as they remained caught in the structural dynamics they sought to address.

Reproducibility and implementation of a rapid, community-based COVID-19 "test and respond" model in low-income, majority-Latino communities in Northern California. PLos One, 17(10). https://doi.org/10.1371/journal.pone.0276257 (Original work published 2022)

Objective: To evaluate implementation of a community-engaged approach to scale up COVID-19 mass testing in low-income, majority-Latino communities.

Methods: In January 2021, we formed a community-academic "Latino COVID-19 Collaborative" with residents, leaders, and community-based organizations (CBOs) from majority-Latinx, low-income communities in three California counties (Marin/Merced/San Francisco). The collaborative met monthly to discuss barriers/facilitators for COVID-19 testing, and plan mass testing events informed by San Francisco's Unidos en Salud "test and respond" model, offering community-based COVID-19 testing and post-test support in two US-census tracts: Canal (Marin) and Planada (Merced). We evaluated implementation using the RE-AIM framework. To further assess testing barriers, we surveyed a random sample of residents who did not attend the events.

Results: Fifty-five residents and CBO staff participated in the Latino collaborative. Leading facilitators identified to increase testing were extended hours of community-based testing and financial support during isolation. In March-April 2021, 1,217 people attended mass-testing events over 13 days: COVID-19 positivity was 3% and 1% in Canal and Planada, respectively. The RE-AIM evaluation found: census tract testing coverage of 4.2% and 6.3%, respectively; 90% of event attendees were Latino, 89% had household income <$50,000/year, and 44% first-time testers (reach), effectiveness in diagnosing symptomatic cases early (median isolation time: 7 days) and asymptomatic COVID-19 (41% at diagnosis), high adoption by CBOs in both counties, implementation of rapid testing (median: 17.5 minutes) and disclosure, and post-event maintenance of community-based testing. Among 265 non-attendees surveyed, 114 (43%) reported they were aware of the event: reasons for non-attendance among the 114 were insufficient time (32%), inability to leave work (24%), and perceptions that testing was unnecessary post-vaccination (24%) or when asymptomatic (25%).

Conclusion: Community-engaged mass "test and respond" events offer a reproducible approach to rapidly increase COVID-19 testing access in low-income, Latinx communities.
