Personal Outcomes in Community-based Participatory Research Partnerships: A Cross-site Mixed Methods Study.
American journal of community psychology
Community-based participatory research (CBPR) has been embraced by diverse populations to address health inequities within their communities. CBPR has been shown to produce favorable health outcomes, but little is known about personal outcomes (e.g., individual growth and capacities) resulting from the direct involvement in a CBPR partnership. We empirically examine which CBPR partnerships' processes and practices are associated with personal outcomes. We hypothesize that higher levels of collaborative approaches and adherence to CBPR principles and practices would be associated with personal outcomes. Based on a national cross-site CBPR study, Research for Improved Health, we utilized mixed-method data from a comprehensive community-engagement survey (N = 450) and seven in-depth case studies to explore the hypothesized relationships. Our multivariate mixed-effects model revealed the importance of various partnering practices. Relationship dynamics emerged as key predictors including the following: respect in the partnership, voice and influence in decision-making among partners, and stewardship. Qualitative findings highlighted individual, partnership, and community-level impacts, within and beyond the partnership. Our findings have implications for CBPR best practices and highlight the potential role of personal outcomes for partnerships' sustainability, long-term outcomes, and health equity research.

Testing the effectiveness of physical activity advice delivered via text messaging vs. human phone advisors in a Latino population: The On The Move randomized controlled trial design and methods.
Contemporary clinical trials
Physical inactivity is a key risk factor for a range of chronic diseases and conditions, yet, approximately 50% of U.S. adults fall below recommended levels of regular aerobic physical activity (PA). This is particularly true for ethnic minority populations such as Latino adults for whom few culturally adapted programs have been developed and tested. Text messaging (SMS) represents a convenient and accessible communication channel for delivering targeted PA information and support, but has not been rigorously evaluated against standard telehealth advising programs. The objective of the On The Move randomized controlled trial is to test the effectiveness of a linguistically and culturally targeted SMS PA intervention (SMS PA Advisor) versus two comparison conditions: a) a standard, staff-delivered phone PA intervention (Telephone PA Advisor) and b) an attention-control arm consisting of a culturally targeted SMS intervention to promote a healthy diet (SMS Nutrition Advisor). The study sample (N = 350) consists of generally healthy, insufficiently active Latino adults ages 35 years and older living in five northern California counties. Study assessments occur at baseline, 6, and 12 months, with a subset of participants completing 18-month assessments. The primary outcome is 12-month change in walking, and secondary outcomes include other forms of PA, assessed via validated self-report measures and supported by accelerometry, and physical function and well-being variables. Potential mediators and moderators of intervention success will be explored to better determine which subgroups do best with which type of intervention. Here we present the study design and methods, including recruitment strategies and yields. Trial Registration: clinicaltrial.gov Identifier = NCT02385591.

Employing Participatory Citizen Science Methods to Promote Age-Friendly Environments Worldwide.
International journal of environmental research and public health
2020; 17 (5)
The trajectory of aging is profoundly impacted by the physical and social environmental contexts in which we live. While "top-down" policy activities can have potentially wide impacts on such contexts, they often take time, resources, and political will, and therefore can be less accessible to underserved communities. This article describes a "bottom-up", resident-engaged method to advance local environmental and policy change, called Our Voice, that can complement policy-level strategies for improving the health, function, and well-being of older adults. Using the World Health Organization's age-friendly cities global strategy, we describe the Our Voice citizen science program of research that has specifically targeted older adults as environmental change agents to improve their own health and well-being as well as that of their communities. Results from 14 Our Voice studies that have occurred across five continents demonstrate that older adults can learn to use mobile technology to systematically capture and collectively analyze their own data. They can then successfully build consensus around high-priority issues that can be realistically changed and work effectively with local stakeholders to enact meaningful environmental and policy changes that can help to promote healthy aging. The article ends with recommended next steps for growing the resident-engaged citizen science field to advance the health and welfare of all older adults.

Exploring health and well-being in Taiwan: what we can learn from individuals' narratives.
BMC public health
2020; 20 (1): 159
Our aim was to explore the concepts of health and well-being from the point of view of the people experiencing them. Most of the efforts to understand these concepts have focused on disease prevention and treatment. Less is known about how individuals achieve health and well-being, and their roles in the pursuit of a good life. We hoped to identify important components of these concepts that may provide new targets and messages to strengthen existing public health programs. An improved understanding of health and well-being - or what it means to be well - can guide interventions that help people lead healthier, more fulfilling lives.Using a grounded qualitative approach drawing from narrative inquiry, we interviewed 24 Taiwanese adults. Thematic inductive coding was employed to explore the nature of health and well-being.Eight constituent domains emerged regarding well-being and health. While the same domains were found for both constructs, important frequency differences were found when participants discussed health versus well-being. Physical health and lifestyle behaviors emerged as key domains for health. Disease-related comments were the most frequently mentioned sub-category within the physical health domain, along with health care use and aging-related changes. For well-being, family and finances emerged as key domains. Family appears to be a cornerstone element of well-being in this sample, with participants often describing their personal well-being as closely tied to - and often indistinguishable from - their family. Other domains included work-life, sense of self, resilience, and religion/spirituality.Health and well-being are complex and multifaceted constructs, with participants discussing their constituent domains in a very interconnected manner. Programs and policies intended to promote health and well-being may benefit from considering these domains as culturally-appropriate leverage points to bring about change. Additionally, while the domains identified in this study are person-centered (i.e., reflecting the personal experiences of participants), the stories that participants offered provided insights into how well-being and health are influenced by structural, societal and cultural factors. Our findings also offer an opportunity for future refinement and rethinking of existing measurement tools surrounding these constructs.

Power Dynamics in Community-Based Participatory Research: A Multiple-Case Study Analysis of Partnering Contexts, Histories, and Practices.
Health education & behavior : the official publication of the Society for Public Health Education
2019; 46 (1_suppl): 19S–32S
Community-based participatory research has a long-term commitment to principles of equity and justice with decades of research showcasing the added value of power-sharing and participatory involvement of community members for achieving health, community capacity, policy, and social justice outcomes. Missing, however, has been a clear articulation of how power operates within partnership practices and the impact of these practices on outcomes. The National Institutes of Health-funded Research for Improved Health study (2009-2013), having surveyed 200 partnerships, then conducted seven in-depth case studies to better understand which partnership practices can best build from community histories of organizing to address inequities. The diverse case studies represented multiple ethnic-racial and other marginalized populations, health issues, and urban and rural areas and regions. Cross-cutting analyses of the qualitative results focus on how oppressive and emancipatory forms of power operate within partnerships in response to oppressive conditions or emancipatory histories of advocacy within communities. The analysis of power was conducted within each of the four domains of the community-based participatory research conceptual model, starting from how contexts shape partnering processes to impact short-term intervention and research outputs, and contribute to outcomes. Similarities and differences in how partnerships leveraged and addressed their unique contexts and histories are presented, with both structural and relational practices that intentionally addressed power relations. These results demonstrate how community members draw from their resilience and strengths to combat histories of injustice and oppression, using partnership principles and practices toward multilevel outcomes that honor community knowledge and leadership, and seek shared power, policy, and community transformation changes, thereby advancing health equity.

Community-Based Participatory Research (CBPR): Towards Equitable Involvement of Community in Psychology Research
2018; 73 (7): 884–98
Community-based participatory research (CBPR) answers the call for more patient-centered, community-driven research approaches to address growing health disparities. CBPR is a collaborative research approach that equitably involves community members, researchers, and other stakeholders in the research process and recognizes the unique strengths that each bring. The aim of CBPR is to combine knowledge and action to create positive and lasting social change. With its origins in psychology, sociology, and critical pedagogy, CBPR has become a common research approach in the fields of public health, medicine, and nursing. Although it is well aligned with psychology's ethical principles and research aims, it has not been widely implemented in psychology research. The present article introduces CBPR to a general psychology audience while considering the unique aims of and challenges in conducting psychology research. In this article, we define CBPR principles, differentiate it from a more traditional psychology research approach, retrace its historical roots, provide concrete steps for its implementation, discuss its potential benefits, and explore practical and ethical challenges for its integration into psychology research. Finally, we provide a case study of CBPR in psychology to illustrate its key constructs and implementation. In sum, CBPR is a relevant, important, and promising research framework that may guide the implementation of more effective, culturally appropriate, socially just, and sustainable community-based psychology research.

CULTURALLY SENSITIVE ASSESSMENTS AS A STRENGTH-BASED APPROACH TO WELLNESS IN NATIVE COMMUNITIES: A COMMUNITY-BASED PARTICIPATORY RESEARCH PROJECT
AMERICAN INDIAN AND ALASKA NATIVE MENTAL HEALTH RESEARCH
2016; 23 (3): 271–92
American Indians and Alaska Natives (AI/ANs) have a unique, traumatic, and alienating history of education in the U.S., which may be directly related to overall health and well-being. Community engagement is critical in well-being research with Native communities, especially when investigating culturally sensitive topics, such as early education experiences. This study investigates the value of a community-based participatory research approach in gaining valuable culturally sensitive information from Native people in a respectful manner. Assessment participation and feedback are analyzed and presented as indicators of Native participant engagement success in a potentially sensitive research project exploring early education experiences.
