Applications of Participatory System Dynamics Methods to Public Health: A Systematic Review.

System dynamics, and specifically qualitative participatory applications of system dynamics, have potential to benefit public health research, scholarship, and practice. A systematic review was conducted to examine the existing applications of participatory system dynamics (PSD) to public health research. Three databases were searched using unique search terms related to PSD and methodological applications in public health research. A total of 57 unique articles met inclusion criteria and were included for review. The studies included for review were conducted globally and represent a wide breadth of public health issues. The review identified several advantages to adopting PSD methods in public health scholarship and practice. The PSD methods provide innovative frameworks for conceptualizing complex and nuanced public health problems. The participatory nature of PSD allows for increased community engagement and empowerment to address public health problems, as well as to mitigate existing power dynamics between research institutions and marginalized communities that are disproportionately impacted by social and health inequities. Finally, causal loop diagrams developed using PSD methods have unique potential to convey complex concepts to policy makers and interventionists. This systematic review reports evidence for PSD's potential to advance equity in public health research and practice.

"Their help is not helping": Policing as a Tool of Structural Violence against Black Communities.

Objective: To illustrate Black youth's perceptions of police violence in West Louisville, Kentucky, how they make sense of it, and their responses to it. Method: The study used qualitative interviews with youth ages 10 to 24 residing in West Louisville. The interviews did not specifically inquire about experiences with police, but the theme emerged so strongly from the overall analysis that the current study was warranted. The research team employed a constructivist analytic approach. Results: The analysis yielded two overarching themes, each with several subthemes. The first theme was Black youth experience profiling and harassment by police, with subthemes focused on youth feeling targeted, youth recognizing policing as a tactic to remove them from their community, and youth being acutely aware of police-involved violence. The second theme was Black youth's experiences with the police cultivates mistrust and unsafety, with subthemes including police seen as more likely to harm than help, police not resolving injustices against Black people, and police presence escalating conflict in Black communities. Conclusions: Youth's narratives regarding their experiences with police highlight the physical and psychological violence enacted by police who come into their community, supported by the law enforcement and criminal justice systems. Youth recognize systemic racism in these systems and how it affects officers' perceptions of them. The long-term implications of persistent structural violence these youth endure has implications on their physical and mental health and wellbeing. Solutions must focus on transforming structures and systems.

Public Health's Next Step in Advancing Equity: Re-evaluating Epistemological Assumptions to Move Social Determinants From Theory to Practice.

The field of public health has increasingly promoted a social ecological approach to health, shifting from an individual, biomedical paradigm to a recognition of social and structural determinants of health and health equity. Yet despite this shift, public health research and practice continue to privilege individual- and interpersonal-level measurements and interventions. Rather than adapting public health practice to social ecological theory, the field has layered new concepts ("root causes," "social determinants") onto a biomedical paradigm-attempting to answer questions presented by the social ecological schema with practices developed in response to biomedicine. This stymies health equity work before it begins-limiting the field's ability to broaden conceptions of well-being, redress histories of inequitable knowledge valuation, and advance systems-level change. To respond effectively to our knowledge of social determinants, public health must resolve the ongoing disconnect between social ecological theory and biomedically-driven practice. To that end, this article issues a clarion call to complete the shift from a biomedical to a social ecological paradigm, and provides a basis for moving theory into practice. It examines biomedicine's foundations and limitations, glosses existing critiques of the paradigm, and describes health equity challenges presented by over-reliance on conventional practices. It then offers theoretical and epistemological direction for developing innovative social ecological strategies that advance health equity.

Public Health's Approach to Systemic Racism: a Systematic Literature Review.

OBJECTIVES: Recently, public health has acknowledged racism as a social determinant of health. Much evidence exists on the impact of individual-level racism and discrimination, with little to no examination of racism from the standpoint of systems and structures. The purpose of this systematic literature review is to analyze the extent to which public health currently addresses systemic racism in the published literature. METHODS: Utilizing the PRISMA guidelines, this review examines three widely used databases to examine published literature covering the topic as well as implications for future research and practice. RESULTS: A total of 85 articles were included in the review analysis after meeting study criteria. CONCLUSIONS: Across numerous articles, the terms racism and systemic racism are largely absent. A critical need exists for an examination of the historical impact of systemic racism on the social determinants of health and health of marginalized populations.

Critical Reflexivity of Communities on Their Experience to Improve Population Health.

Although community capacity has been prominent in the public health literature for nearly 20 years, the field has only operationalized a few dimensions. An intriguing dimension of capacity is a community's ability to critically reflect. On the basis of previous research as well as theoretical and practical insights from management and organizational learning literature, we offer a process framework for critical reflexivity practice in community. The framework draws on ideas regarding cognition and agency, praxis, as well as the transformative learning model to conceptualize how reflexivity happens as an emergent community process. The implication is that reflexivity is a community-level process of making meaning of experiences that drive a common narrative. Inclusivity and establishing consensus are paramount, and can be difficult in light of power dynamics and consideration of dissenting voices and different experiences; enlightened self-interest and creating conducive spaces for dialogue are key in this process. Strengthening communities' ability to gain and employ collective wisdom from their experience will also build their overall capacity for population health improvement.

Assessing Community Leadership: Understanding Community Capacity for Health Improvement.

OBJECTIVE: The purpose of this study was to pilot a quantitative instrument to measure aspects of community leadership within an assessment framework. DESIGN: The instrument includes 14 Likert-type questions asking residents how they perceive leaders within 5 sectors: Louisville Metro Council/Mayor's Office, the faith community, education, business, and the civic sector. SETTING: Louisville/Jefferson County, Kentucky, has a population of about 743 000 residents. Respondents were asked to examine leadership within West Louisville, an economically deprived area of the city made up of 9 contiguous neighborhoods. This area is predominantly African American (78% compared with 22% in Louisville Metro), with an overall poverty rate of 43% (compared with 18% in Louisville Metro), and unemployment rate of 23% (compared with 8% in Louisville Metro). Residents of West Louisville are looking to leadership to address many of the inequities. PARTICIPANTS: Twenty-seven participants representing 7 community sectors completed the survey, of whom 90% work in West Louisville. MAIN OUTCOME MEASURE(S): The instrument measured local perceptions of leadership strength, effectiveness, trust, communication, community building, and leadership development. RESULTS: The majority of respondents agree that strong leadership exists across the 5 sectors, with variation regarding perceptions of the quality of that leadership. City leadership within the Mayor's Office and Metro Council is largely viewed positively, while the growing tensions within the education sector were reflected in the survey results. CONCLUSION: The perception of community leadership is important to understanding local community capacity to improve health and also inclusivity of community voice in the assessment and community improvement processes. Results from such assessments can offer useful information for strengthening community capacity and sustaining relationships needed to enact progressive and equitable solutions to address local issues. Leaders in a variety of settings can utilize this instrument to improve their community as well as their practical approaches towards leadership and equity.

Using a Community Health Development Framework to Increase Community Capacity: A Multiple Case Study.

The Physical Activity and Community Engagement Project utilized a comparative case study to understand how a theoretical framework called community health development (CHD) influences community capacity. Three rural communities (cases) developed interventions using a CHD framework. Researchers collected qualitative evidence measuring capacity and the CHD process for more than 3 years. Patterns identified seven capacity constructs relevant to CHD, including community history, civic participation, leadership, skills, resources, social and interorganizational networks, and critical reflection. Community health development focuses on population health improvement and strengthening community capacity. As such, it helps communities address local priorities and equips them to address future issues.
