Exploring theoretical mechanisms of community-engaged research: a multilevel cross-sectional national study of structural and relational practices in community-academic partnerships.

BACKGROUND: Community-Based Participatory Research (CBPR) is often used to address health inequities due to structural racism. However, much of the existing literature emphasizes relationships and synergy rather than structural components of CBPR. This study introduces and tests new theoretical mechanisms of the CBPR Conceptual Model to address this limitation. METHODS: Three-stage online cross-sectional survey administered from 2016 to 2018 with 165 community-engaged research projects identified through federal databases or training grants. Participants (N = 453) were principal investigators and project team members (both academic and community partners) who provided project-level details and perceived contexts, processes, and outcomes. Data were analyzed through structural equation modeling and fuzzy-set qualitative comparison analysis. RESULTS: Commitment to Collective Empowerment was a key mediating variable between context and intervention activities. Synergy and Community Engagement in Research Actions were mediating variables between context/partnership process and outcomes. Collective Empowerment was most strongly aligned with Synergy, while higher levels of Structural Governance and lower levels of Relationships were most consistent with higher Community Engagement in Research Actions. CONCLUSIONS: The CBPR Conceptual Model identifies key theoretical mechanisms for explaining health equity and health outcomes in community-academic partnerships. The scholarly literature's preoccupation with synergy and relationships overlooks two promising practices-Structural Governance and Collective Empowerment-that interact from contexts through mechanisms to influence outcomes. These results also expand expectations beyond a "one size fits all" for reliably producing positive outcomes.

The Social Determinants of Perinatal Maternal Distress.

This pilot study examined associations between prenatal individual and socioenvironmental determinants of health and symptoms of perinatal maternal distress (PMD) in women enrolled in midwifery practice and living in a rural state. Pearson's correlations between prenatal predictors and PMD scores were calculated. Having experienced emotional abuse in one's lifetime, total number of past year stressors, and everyday discrimination score were all statistically significant predictors of PMD at study enrollment and follow-up. Result suggest shifting to a multi-symptom, life course assessment and intervention paradigm, tailored to the context of specific populations, may improve perinatal care and reduce disparities.

Social Support Protects Against Symptoms of Anxiety and Depression: Key Variations in Latinx and Non-Latinx White College Students.

Social support protects against perceived stress and its harmful effects on psychological well-being. College students in general are at high risk for mental health disorders, and Latinx college students face unique stressors placing them at greater risk of psychological distress. Social support may be a key construct in improving outcomes for college students; however, few studies have empirically tested whether the protective effect of social support is equivalent across racial/ethnic groups. Using a series of regression models, we investigated whether social support moderates the relationship between perceived stress and endorsement of depression and anxiety symptoms in Latinx (n = 265) and non-Latinx White college students (n = 216) and whether this moderating effect varied by group membership. Participants completed a series of questionnaires measuring social support, perceived stress, and depression and anxiety symptoms. The moderating effects of social support varied by group membership and outcomes (i.e., depression and anxiety). Social support moderated the relationship between perceived stress and depression symptoms for both Latinx and non-Latinx White students. However, social support only buffered the effect of perceived stress on anxiety symptom endorsement for Latinx college students. These findings suggest that social support does not function uniformly across racial/ethnic groups or the endorsement of depression and anxiety symptoms. Social support may be particularly important for Latinx students by providing a buffer between perceived stress and symptoms of anxiety.

El apoyo social protege contra el estrés y sus efectos en el bienestar psicológico. El riesgo de desarrollar trastornos psicológicos es elevado en estudiantes universitarios. Estudiantes universitarios Latinxs enfrentan situaciones relacionadas con identificatión de minoría que pueden contribuir a una elevación en el riesgo de desarrollar problemas psicológicos. Como tal, el apoyo social es un área clave para la preventión y mejoría del bienestar psicológico. Sin embargo, pocas investigaciones han comparado los efectos protectores del apoyo social a través de raza y etnia. Usamos una serie de modelos de regresión para investigar si el apoyo social modera la relación entre la percepción de estrés y el reporte de síntomas de depresión y ansiedad en estudiantes universitarios Latinxs y anglosajones. Además, investigamos si este efecto de moderación varia en dependencia de la membresía etnia. Participantes completaron una serie de cuestionarios midiendo variables de interés, incluyendo apoyo social, percepcicón de estrés, síntomas de depresión y ansiedad. El apoyo social modera la relación entre la percepcición de estrés y síntomas de depresión en los dos grupos étnicos, Latinxs y anglosajones. Sin embargo, para los síntomas de ansiedad, el efecto protector del apoyo social fue distinto para los estudiantes Latinxs. Estos resultados sugieren que la función del apoyo social no es uniforme a través de grupos étnicos o en términos de protectión contra diferentes problemas psicológicos. El apoyo social es particularmente importante para los estudiantes Latinxs en términos de proveer protectión contra síntomas de ansiedad en la presencia de la perceptión del estrés.

Outcomes of a Community-Based Participatory Research Partnership Self-Evaluation: The Rochester Healthy Community Partnership Experience.

BACKGROUND: Community-based participatory research (CBPR) can effectively address health disparities among groups that are historically difficult to reach, disadvantaged, of a minority status, or are otherwise underrepresented in research. Recent research has focused on the science of CBPR partnership constructs and on developing and testing tools for self-evaluation. Because CBPR requires substantial investment in human and material resources, specific factors that support successful and sustainable research partnerships must be identified. We sought to describe the evolution, implementation, and results of a self-evaluation of a CBPR partnership. METHODS: Academic and community members of the Rochester Healthy Community Partnership (RHCP) and researchers from the University of New Mexico-Center for Participatory Research collaborated to evaluate RHCP with qualitative and quantitative research methods and group analysis. RESULTS: The self-evaluation was used to provide an overall picture of the "health" of the partnership, in terms of sustainability and ability to effectively collaborate around community priorities. RHCP members revisited the partnership's mission and values; identified associations between partnership practices, dynamics, and outcomes; and elicited insight from community and academic partners to help guide decisions about future directions and the sustainability of the partnership. Positive partnership dynamics were associated with perceived improvements in health and equity outcomes. CONCLUSIONS: Although engaging in a comprehensive self-evaluation requires substantial investment from stakeholders, such assessments have significant value because they enable partners to reflect on the mission and values of the partnership, explore the history and context for its existence, identify factors that have contributed to outcomes, and plan strategically for the future.

Structural Community Governance: Importance for Community-Academic Research Partnerships.

Community based participatory research (CBPR) emphasizes democratic knowledge production and joint action between academics and communities to promote health equity through multilevel interventions. While much scholarship has expressed a commitment to collaboration between researchers and communities, effective methods of structural governance between community and academic stakeholders is under explored. We fill this gap by presenting a conceptual and empirical analysis describing multiple dimensions of structural governance in CBPR partnerships. First, we integrate public policy evidence on effective collaborative governance designs with the emerging literature in CBPR to create a conceptual model. Next, we utilize internet surveys of 179 federally funded community engaged research projects to construct and assess a measure of structural governance across multiple dimensions using confirmatory factor analysis. We explore whether antecedent factors such as the stage of the partnership and ethnic composition are associated with these dimensions and we examine associations for each of these components on positive perceptions of community involvement of research and collective empowerment. We develop a robust multidimensional measure of structural governance that is positively associated with perceptions of increased community involvement in research and collective empowerment.

Scales of Practices and Outcomes for Community-Engaged Research.

Despite the growth of research on community-engaged research (CEnR), recent reviews suggest there has been limited development of validated scales to measure key contexts, mechanisms, and outcomes, impairing testing and refinement of theoretical models. The purpose of this study is to present the psychometric properties of scales from the Engage for Equity (E2) project, stemming from a long-term research partnership examining community-engaged research projects. This study used a three-stage, cross-sectional format: (a) a sampling frame of 413 CEnR projects was identified; (b) 210 principal investigators completed a project-level survey and nominated partners for another survey; (c) 457 investigators and partners completed a survey about project contexts, processes, interventions, and outcomes. Factorial validity was established through confirmatory factor analysis supporting seven scales: contextual capacity, commitment to collective empowerment, relationships, community engagement in research actions, synergy, partner and partnership transformation, and projected outcomes. Convergent validity was established through examining covariances among the scales. This study largely yielded results consistent with a previous psychometric study of related measures, while demonstrating improved ceiling effects of the items and refined conceptualization of core theoretical constructs.

Engage for Equity: The Role of Trust and Synergy in Community-Based Participatory Research.

Community-based participatory research (CBPR) partnerships exist as complex, dynamic relationships that incorporate shared decision that supports trust development between communities and academics. Within CBPR, the interest in understanding the concept of trust has grown with the realization that, without trust, CBPR relationships fracture. A barrier to monitoring the trust health of a partnership is the lack of a shared operationalization of the concept, its antecedents, and measurement tools. To address these barriers, a six-category trust typology was created as a developmental theory of trust progress. To advance the theory, this article reports on the quantitative structural elements of the trust typology, identifies variability in trust correlates, and creates an empirical foundation for the trust types. Using Engage for Equity data, trust covariates included measures of synergy, CBPR principles, participation, and influence. Structural equation models were used to assess associations between trust types and the latent constructs measured by the items in each measure. The findings demonstrate that the six trust types generally operate on a continuum. Specifically, it does appear that trust deficit, role-based trust, functional trust, proxy trust, and reflective trust are on a single continuum from low to high. Scale scores for reflective trust and proxy trust were consistently and statistically significantly higher than those for functional trust, role-based, neutral, and trust deficit. These results support the construct validity of the trust typology as representing "higher levels" of trust phases. Due to the dynamic nature of partnerships, regular monitoring of partnership trust types can serve as a proxy for partnership functioning.

Engage for Equity: Development of Community-Based Participatory Research Tools.

We developed a set of four community-based participatory research (CBPR) partnership tools aimed at supporting community-academic research partnerships in strengthening their research processes, with the ultimate goal of improving research outcomes. The aim of this article is to describe the tools we developed to accomplish this goal: (1) the River of Life Exercise; (2) a Partnership Visioning Exercise; (3) a personalized Partnership Data Report of data from academic and community research partners; and (4) a Promising Practices Guide with aggregated survey data analyses on promising CBPR practices associated with CBPR and health outcomes from two national samples of CBPR projects that completed a series of two online surveys. Relying on Paulo Freire's philosophy of praxis, or the cycles of collective reflection and action, we developed a set of tools designed to support research teams in holding discussions aimed at strengthening research partnership capacity, aligning research partnership efforts to achieve grant aims, and recalling and operationalizing larger social justice goals. This article describes the theoretical framework and process for tool development and provides preliminary data from small teams representing 25 partnerships who attended face-to-face workshops and provided their perceptions of tool accessibility and intended future use.

Engage for Equity: A Long-Term Study of Community-Based Participatory Research and Community-Engaged Research Practices and Outcomes.

Community-based participatory research (CBPR) and community-engaged research have been established in the past 25 years as valued research approaches within health education, public health, and other health and social sciences for their effectiveness in reducing inequities. While early literature focused on partnering principles and processes, within the past decade, individual studies, as well as systematic reviews, have increasingly documented outcomes in community support and empowerment, sustained partnerships, healthier behaviors, policy changes, and health improvements. Despite enhanced focus on research and health outcomes, the science lags behind the practice. CBPR partnering pathways that result in outcomes remain little understood, with few studies documenting best practices. Since 2006, the University of New Mexico Center for Participatory Research with the University of Washington's Indigenous Wellness Research Institute and partners across the country has engaged in targeted investigations to fill this gap in the science. Our inquiry, spanning three stages of National Institutes of Health funding, has sought to identify which partnering practices, under which contexts and conditions, have capacity to contribute to health, research, and community outcomes. This article presents the research design of our current grant, Engage for Equity, including its history, social justice principles, theoretical bases, measures, intervention tools and resources, and preliminary findings about collective empowerment as our middle range theory of change. We end with lessons learned and recommendations for partnerships to engage in collective reflexive practice to strengthen internal power-sharing and capacity to reach health and social equity outcomes.

Characteristics and Practices Within Research Partnerships for Health and Social Equity.

BACKGROUND: As federal research funding focuses more on academic/community collaborations to address health inequities, it is important to understand characteristics of these partnerships and how they work to achieve health equity outcomes. OBJECTIVES: This study built on previous National Institutes of Health-funded research to (a) describe partnership characteristics and processes of federally funded, community-based participatory research (CBPR) or community-engaged research projects; (b) explore characteristics of these projects by stage of funding; and (c) build on previous understanding of partnership promising practices. METHODS: Between fall 2016 and spring 2017, we completed a cross-sectional analysis and principal component analysis of online survey data from key informants of federally funded CBPR and community-engaged research projects. Respondents for 179 projects (53% response rate) described project characteristics (e.g., type of partner, stage of partnership, and population) and the use of promising practices (e.g., stewardship, advisory board roles, training topics) by stage of partnership. RESULTS: Projects involved community, healthcare, and government partners, with 49% of respondents reporting their project was in the early stage of funding. More projects focused on Black/African American populations, whereas principal investigators were mostly White. The more established a partnership (e.g., with multiple projects), the more likely it employed the promising practices of stewardship (i.e., community safeguards for approval), community advisory boards, and training on values and power. CONCLUSIONS: Community engagement is a developmental process with differences between early-stage and established CBPR partnerships. Engaging in active reflection and adopting promising partnering practices are important for CBPR partnerships working to improve health equity. The data provided in this study provide key indicators for reflection.

Racial/Gender Biases in Student Clinical Decision-Making: a Mixed-Method Study of Medical School Attributes Associated with Lower Incidence of Biases.

BACKGROUND: Accumulating evidence suggests that clinician racial/gender decision-making biases in some instances contribute to health disparities. Previous work has produced evidence of such biases in medical students. OBJECTIVE: To identify contextual attributes in medical schools associated on average with low levels of racial/gender clinical decision-making biases. DESIGN: A mixed-method design using comparison case studies of 15 medical schools selected based on results of a previous survey of student decision-making bias: 7 schools whose students collectively had, and 8 schools whose students had not shown evidence of such biases. PARTICIPANTS: Purposively sampled faculty, staff, underrepresented minority medical students, and clinical-level medical students at each school. MAIN MEASURES: Quantitative descriptive data and qualitative interview and focus group data assessing 32 school attributes theorized in the literature to be associated with formation of decision-making and biases. We used a mixed-method analytic design with standard qualitative analysis and fuzzy set qualitative comparative analysis. KEY RESULTS: Across the 15 schools, a total of 104 faculty, administrators and staff and 21 students participated in individual interviews, and 196 students participated in 29 focus groups. While no single attribute or group of attributes distinguished the two clusters of schools, analysis showed some contextual attributes were seen more commonly in schools whose students had not demonstrated biases: longitudinal reflective small group sessions; non-accusatory approach to training in diversity; longitudinal, integrated diversity curriculum; admissions priorities and action steps toward a diverse student body; and school service orientation to the community. CONCLUSIONS: We identified several potentially modifiable elements of the training environment that are more common in schools whose students do not show evidence of racial and gender biases.

Place and Policy: Secondhand Smoke Exposure in Bars and Restaurants.

BACKGROUND: Rural populations have been identified as having tobacco use disparities, with contributing factors including less demand for policy change than in urban areas, resulting in higher age-adjusted death rates related to tobacco use. In 2012, the rural state of North Dakota enacted a statewide comprehensive law requiring all bars and restaurants to be smoke-free. OBJECTIVES: The purpose of this longitudinal study, performed in three phases, was to assess the continued effects of a statewide comprehensive smoke-free law in a primarily rural state, using a stratified random sample. METHODS: Particulate matter and compliance indicators were assessed in restaurants and bars 21 months after enactment of the comprehensive law. Results were compared with the findings from the Phase 1 and Phase 2 samples, in which venues were assessed before passage of the law and approximately 3 months after enactment, respectively. RESULTS: The comprehensive, statewide, smoke-free law led to immediate, sustained, and substantial reductions in secondhand smoke and eliminated previous significant disparities in secondhand smoke exposure in rural communities. Although indoor smoke-free compliance with the law was generally high, compliance in required outdoor smoke-free areas was low. Compliance with signage requirements, both indoors and outdoors, was low. DISCUSSION: The comprehensive statewide smoke-free law created a just distribution of smoke-free laws statewide, resulting in increased protection of rural populations from secondhand smoke. Targeted public health interventions to address compliance may reduce secondhand smoke levels in outlier venues that continue to have high levels of secondhand smoke.

Tobacco Smoke Pollution in Hospitality Venues Before and After Passage of Statewide Smoke-Free Legislation.

OBJECTIVE: In 2012, North Dakota enacted a comprehensive statewide law prohibiting smoking in enclosed public places. Disparities in tobacco control exist in rural areas. This study's objective was to determine the extent to which the passage of a comprehensive, statewide, smoke-free law in a predominantly rural state influenced tobacco smoke pollution in rural and nonrural venues. DESIGN AND SAMPLE: A longitudinal cohort design study comparing the levels of tobacco smoke pollution before and after passage of the statewide smoke-free law was conducted in 64 restaurants and bars statewide in North Dakota. MEASURES: Particulate matter with a median aerodynamic diameter of <2.5 µm (a valid atmospheric marker of tobacco smoke pollution) was assessed. RESULTS: A significant 83% reduction in tobacco smoke pollution levels occurred after passage of the law. Significant reductions in tobacco smoke pollution levels occurred in each of the rural categories; however, no difference by rurality was noted in the analysis after passage of the law, in contrast to the study before passage. CONCLUSIONS: To our knowledge, this was the largest, single, rural postlaw study globally. A comprehensive statewide smoke-free law implemented in North Dakota dramatically decreased the level of tobacco smoke pollution in bars and restaurants.

Adherence to the Women's Preventive Services Guidelines in the Affordable Care Act.

OBJECTIVE: To assess the adherence of women's health providers in New Mexico to the Women's Preventive Services Guidelines and to examine how providers' knowledge, attitudes, and external barriers are associated with adherence. DESIGN: Cross-sectional, descriptive survey. SETTING: New Mexico. PARTICIPANTS: Women's health providers in New Mexico, including nurse practitioners, certified nurse-midwives, and family practice and obstetrician-gynecologist physicians. METHODS: Participants completed a self-administered survey to measure knowledge, attitudes, external barriers, and adherence to each of the eight guidelines. Adherence was defined as following a guideline more than 90% of the time. RESULTS: The response rate was 22% (399/1,798). Among the eight guidelines, participant adherence ranged from 17.2% to 88.4%. Only 39.7% of participants indicated adherence to most of the guidelines (four or more). Overall, provider adherence was directly associated with familiarity with the guidelines (odds ratio = 3.69; 95% confidence interval [1.96, 6.96]), self-efficacy to implement them (odds ratio = 4.25; 95% confidence interval [2.21, 8.20]), and younger age (odds ratio = 0.97; 95% confidence interval [0.94, 1.00]). CONCLUSION: Adherence to the Women's Preventive Services Guidelines by providers in New Mexico is variable and, for many recommended practices, less than optimal. New targeted implementation strategies are needed to address barriers to adherence.

Trends in the Supply and Practice Environment of Nurse Practitioners in New Mexico.

This study examines the practice environment for nurse practitioners (NPs) in New Mexico and assesses whether the future supply of NPs will be adequate to meet the health care needs of a varied population in a sparsely populated state with a relatively low average standard of living, yet one that offers a broad scope of practice authority for its NPs. The study's models forecast decreasing numbers of New Mexico NPs between the ages of 40 and 60 in the state's metropolitan counties. These decreases are not offset by gains in other age brackets. Thus, over time, the state's metro areas may not maintain their 2013 NP-to-insured and NP-to-senior population ratios. In contrast, the study's models forecast improving ratios in nonmetropolitan counties. The future need for NPs in New Mexico and similarly situated states may therefore be greatest in fast-growing urban areas, where the number of newly insured individuals with primary care needs is likely to be high.

Place as a predictor of health insurance coverage: A multivariate analysis of counties in the United States.

This study assessed the importance of county characteristics in explaining county-level variations in health insurance coverage. Using public databases from 2008 to 2012, we studied 3112 counties in the United States. Rates of uninsurance ranged widely from 3% to 53%. Multivariate analysis suggested that poverty, unemployment, Republican voting, and percentages of Hispanic and American Indian/Alaskan Native residents in a county were significant predictors of uninsurance rates. The associations between uninsurance rates and both race/ethnicity and poverty varied significantly between metropolitan and non-metropolitan counties. Collaborative actions by the federal, tribal, state, and county governments are needed to promote coverage and access to care.

The impact of state certification of community health workers on team climate among registered nurses in the United States.

A number of states have adopted certification programs for community health workers (CHWs) to improve recognition of CHWs as members of health care teams, increase oversight, and to provide sustainable funding. There has been little research into the impact of state CHW certification on the diffusion and adoption of CHWs into existing health care systems. This study examined the impact of state CHW certification on the perceptions of team climate among registered nurses (RNs) who work with CHWs in states with and without CHW certification programs. The study recruited RNs using a purposeful sampling method and used an online survey, which included the Team Climate Inventory (TCI), and compared the perceptions of team climate between the two groups. The study found no significant differences in the overall mean TCI score or TCI subscale scores between RNs who work in states with CHW certification programs (n = 81) and those who work in states without CHW certification programs (n = 115). There was a statistically significant difference on one survey question regarding whether RNs believe state certification of CHWs improved the ability of their health care team to deliver quality care. More research is needed to assess impact of state certification of CHWs and other factors that influence the diffusion and adoption of CHWs into the current health care system.

Obesity and malnutrition among Hispanic children in the United States: double burden on health inequities.

OBJECTIVE: To examine important micronutrient deficiencies related to child health and growth outcomes for all weight statuses to 1) better understand other potential nutritional problems and inequities that may be masked by focusing solely on BMI percentiles and overweight/obesity, and 2) draw attention to the need for more studies focused on the nutritional well-being of children at all weight statuses, including healthy weight. METHODS: A sample of children (ages 2-19 years) old from the National Health and Nutrition Examination Survey (NHANES) 2003-2010 was analyzed. Prevalence of stunting, folate, vitamin D, iron, iodine, and anemia, was considered. Comparisons were conducted between non-Hispanic whites and Hispanics, and within Hispanics, based on socio-demographic and economic characteristics. RESULTS: Hispanic children experienced significantly higher prevalence of stunting (6.1% versus 2.6%), and the prevalence of stunted Hispanic children in the healthy weight category was higher than those in the overweight/obese category. Comparable percentages were observed by ethnicity for most analyzed micronutrients, although girls had consistently higher prevalence of nutritional deficiencies than boys, especially girls reaching reproductive age. CONCLUSIONS: The results of this article draw attention to the need for more specific and differentiated analyses of child obesity and nutritional status among and within ethnic, sex, and age groups. Appropriate public health interventions need to consider the entire range of weight statuses and micronutrient deficiencies to eliminate inequities among minority children, especially girls.

OBJETIVO: Analizar las carencias importantes de micronutrientes relacionadas con la salud del niño, y los resultados de crecimiento para las distintas situaciones en cuanto a peso, con objeto de 1) comprender mejor otros posibles problemas y desigualdades nutricionales que podrían quedar ocultos al adoptar un enfoque exclusivo en los percentiles de índice de masa corporal, y el sobrepeso y la obesidad, y 2) hacer hincapié en la necesidad de llevar a cabo más estudios que se centren en el bienestar nutricional de los niños en las distintas situaciones en cuanto al peso, incluido el peso saludable. MÉTODOS: Se analizó una muestra de niños (de 2 a 19 años) de la Encuesta Nacional de Salud y Nutrición (NHANES) 2003-2010. Se consideraron las prevalencias del retraso en el crecimiento, de las deficiencias de folato, vitamina D, hierro y yodo, y de la anemia. Se establecieron comparaciones entre blancos no hispanos e hispanos, y entre los mismos hispanos, con base en las características sociodemográficas y económicas. RESULTADOS: Los niños hispanos mostraron una prevalencia significativamente mayor de retraso en el crecimiento (6,1 frente a 2,6%), y la prevalencia del retraso en el crecimiento en los niños hispanos clasificados como de peso saludable fue mayor que en los incluidos en las categorías de sobrepeso u obesidad. Se observaron porcentajes comparables por grupos étnicos en cuanto a los micronutrientes más analizados, aunque las niñas mostraron sistemáticamente una mayor prevalencia de carencias nutricionales que los niños, especialmente las que se acercaban a la edad fecunda. CONCLUSIONES: Los resultados hacen hincapié en la necesidad de llevar a cabo estudios más específicos y diferenciados sobre la obesidad y el estado nutricional de los niños entre y dentro de los distintos grupos étnicos, de sexo y de edad. Las intervenciones de salud pública, para que resulten apropiadas, deben considerar las distintas situaciones en cuanto a peso y las carencias de micronutrientes, con objeto de eliminar las desigualdades en niños de grupos minoritarios, especialmente en niñas.
