Measuring and Testing How Food Policy Councils Function to Influence Their Food Systems

The number of Food Policy Councils (FPCs) in the United States (US), Canada, and Native American & First Nations increased from 43 in 2005 to 278 in 2015. The Centers for Disease Control and Prevention recommend establishing FPCs to improve the local and state food environments. Despite increased interest in FPCs, there is little evidence about what makes FPCs effective. First, we conducted a case study of an FPC in a rural county to understand how a council facilitates change across their food system using interviews (n=8) and network analysis (n=12). Council members indicated that council connections helped them work more effectively in their home organizations. Social network analysis revealed a dense network of connections and complemented qualitative findings. This case study illustrates connections between FPC members in a rural county, and identifies examples of how FPCs can facilitate policy, systems, and environmental-level change in their communities. Next, we developed and tested the Food Policy Council Self-Assessment Tool (FPC-SAT). The assessment measures council members’ perceptions of the following concepts: leadership, breadth of active membership, council climate, formality of council structure, knowledge sharing, relationships, member empowerment, community context, synergy, and impacts on the food system. All 278 FPCs listed on the Food Policy Network’s directory were recruited. Responses from 354 FPC members from 94 councils were used to test the assessment. Cronbach alpha ranged from 0.79 – 0.93 for the scales. FPC members reported the lowest mean scores on the breadth of active membership scale (mean=2.49, SD=0.622) and highest on the leadership scale (mean=3.45, SD=0.452). This study contributes to measurement development and FPC members’ perceptions of how their councils functions. Finally, we used responses from the FPC-SAT to evaluate the relationships between organizational capacity, social capital, and council effectiveness in FPCs. Structural equation modeling was used to test and revise an FPC Framework. A revised FPC Framework was a good fit with the data (n=354, χ2=40.085, df=24, p-value=0.021, CFI=0.988, TLI=0.982, RMSEA=0.044, p-close=0.650). The FPC Framework can guide capacity building interventions and evaluations. The evidence-informed framework can help FPCs efficiently work toward achieving their mission of improving their local food system.Doctor of Philosoph

Using Behavior Over Time Graphs to Spur Systems Thinking Among Public Health Practitioners

Public health practitioners can use Behavior Over Time (BOT) graphs to spur discussion and systems thinking around complex challenges. Multiple large systems, such as health care, the economy, and education, affect chronic disease rates in the United States. System thinking tools can build public health practitioners’ capacity to understand these systems and collaborate within and across sectors to improve population health. BOT graphs show a variable, or variables (y axis) over time (x axis). Although analyzing trends is not new to public health, drawing BOT graphs, annotating the events and systemic forces that are likely to influence the depicted trends, and then discussing the graphs in a diverse group provides an opportunity for public health practitioners to hear each other’s perspectives and creates a more holistic understanding of the key factors that contribute to a trend. We describe how BOT graphs are used in public health, how they can be used to generate group discussion, and how this process can advance systems-level thinking. Then we describe how BOT graphs were used with groups of maternal and child health (MCH) practitioners and partners (N = 101) during a training session to advance their thinking about MCH challenges. Eighty-six percent of the 84 participants who completed an evaluation agreed or strongly agreed that they would use this BOT graph process to engage stakeholders in their home states and jurisdictions. The BOT graph process we describe can be applied to a variety of public health issues and used by practitioners, stakeholders, and researchers

Coalition-Committees as Network Interventions: Baseline Network Composition in Context of Childhood Obesity Prevention Interventions

Community coalitions can address local issues with deep, historic, and contextual understanding that enables customized implementation of evidence-based strategies. The individuals within the coalition, their partnerships, and the social context is likely an important component of unraveling the challenges of implementation so interventions reach people in need. We focus on the relevance of baseline coalition-committee network (CCN), the networks of purposely formed subcommittees within community coalitions, structure as one of the moderating, theoretical links between community coalition social networks and intervention success. We explore the baseline composition and characteristics of five CCNs at the beginning of childhood obesity prevention interventions. Using a combination of social network, multidimensional scaling, and correspondence analyses, we examine the structure and heterogeneity of five CCNs, each consisting of a core group of stakeholders in the coalition and sometimes the broader community itself. Cross-sectional analyses are used to examine the composition of coalition-committees related to network density, centralization, hierarchy, and coalition demographics and characteristics. Results indicate that CCNs are patterned in their structure and characteristics, and we discuss whether adjustments to childhood obesity prevention interventions according to baseline structure and characteristics could be advantageous for intervention implementation. Together, these findings can inform future longitudinal investigations into CCN network structure

Food Policy Council Self-Assessment Tool: Development, Testing, and Results

A large number of food policy councils (FPCs) exist in the United States, Canada, and Tribal Nations (N = 278), yet there are no tools designed to measure their members' perceptions of organizational capacity, social capital, and council effectiveness. Without such tools, it is challenging to determine best practices for FPCs and to measure change within and across councils over time. This study describes the development, testing, and findings from the Food Policy Council Self-Assessment Tool (FPC-SAT). The assessment measures council practices and council members' perceptions of the following concepts: leadership, breadth of active membership, council climate, formality of council structure, knowledge sharing, relationships, member empowerment, community context, synergy, and impacts on the food system. All 278 FPCs listed on the Food Policy Network's Online Directory were recruited to complete the FPC-SAT. Internal reliability (Cronbach's α) and inter-rater reliability (AD, rWG(J), ICC [intraclass correlations][1], ICC[2]) were calculated, and exploratory and a confirmatory factor analyses were conducted. Responses from 354 FPC members from 94 councils were used to test the assessment. Cronbach's α ranged from 0.79 to 0.93 for the scales. FPC members reported the lowest mean scores on the breadth of active membership scale (2.49; standard deviation [SD], 0.62), indicating room for improvement, and highest on the leadership scale (3.45; SD, 0.45). The valid FPC-SAT can be used to identify FPC strengths and areas for improvement, measure differences across FPCs, and measure change in FPCs over time

Does the Direction of Kinesiology Tape Application Influence Muscle Activation in Asymptomatic Individuals?

# Background Despite the popularity of tape among athletes and rehabilitation practitioners, there is controversy regarding the specific effects of kinesiology tape. Based on conflicting results and limitations of the literature, a well-designed study was desired to examine kinesiology tape application direction on muscle activation. # Hypothesis/Purpose The purpose of this pilot study was to determine if the direction of kinesiology tape application influences quadriceps activation. This study compared taping techniques with outcome measures selected to assess quadriceps muscle activation. The outcome measures included EMG, isokinetic strength, and functional hop and jump performance. # Study Design Double-blind Crossover study # Methods A total of fifteen asymptomatic participants (10 females and 5 males) completed the study. Mean age was 23.3 years. Kinesio^Ⓡ^ Tex Gold^TM^ was applied to the dominant lower extremity of each participant using a Y-strip method. Two taping conditions (proximal to distal, distal to proximal) were applied to the quadriceps. Participants and testers were blinded to tape condition. Pretest and posttest measures included electromyographic output during isokinetic testing of quadriceps muscle torque at 60°s^-1^ and 120°s^-1^, single leg triple hop for distance, and vertical jump. # Results Two-way, repeated measures analysis of variance resulted in no significant differences in baseline to taped condition for quadriceps electromyographic output, quadriceps isokinetic knee extension muscle torque at 60°s^-1^ and 120°s^-1^, single leg triple-hop distance or vertical jump height. # Conclusion The results of this pilot study do not support the hypothesis that kinesiology tape application direction influences muscle performance as measured in this study. # Levels of Evidence Level 1 – Controlled Clinical Trial # Clinical Relevance Kinesiology tape is commonly used as an intervention for a wide range of musculoskeletal conditions and for promoting performance including sporting activities. Kinesiology tape is popular among athletes and health care providers yet the specific effects of tape are not well understood

Developing Theory to Guide Building Practitioners’ Capacity to Implement Evidence-Based Interventions

Public health and other community-based practitioners have access to a growing number of evidence-based interventions (EBIs), and yet EBIs continue to be underused. One reason for this underuse is that practitioners often lack the capacity (knowledge, skills, and motivation) to select, adapt, and implement EBIs. Training, technical assistance, and other capacity-building strategies can be effective at increasing EBI adoption and implementation. However, little is known about how to design capacity-building strategies or tailor them to differences in capacity required across varying EBIs and practice contexts. To address this need, we conducted a scoping study of frameworks and theories detailing variations in EBIs or practice contexts and how to tailor capacity-building to address those variations. Using an iterative process, we consolidated constructs and propositions across 24 frameworks and developed a beginning theory to describe salient variations in EBIs (complexity and uncertainty) and practice contexts (decision-making structure, general capacity to innovate, resource and values fit with EBI, and unity vs. polarization of stakeholder support). The theory also includes propositions for tailoring capacity-building strategies to address salient variations. To have wide-reaching and lasting impact, the dissemination of EBIs needs to be coupled with strategies that build practitioners’ capacity to adopt and implement a variety of EBIs across diverse practice contexts

Evaluating Food Policy Councils Using Structural Equation Modeling

At least 282 Food Policy Councils (FPCs) are currently working to improve access to healthy foods in their communities by connecting food system sectors, gathering community input, and advising food policy. Empirical research on FPCs is limited. This study empirically evaluates FPCs to better understand the relationships between Organizational Capacity, Social Capital, and Council Effectiveness by testing a FPC Framework adapted from Allen and colleagues (2012). Members of all FPCs in the U.S., Canada, and Native American Tribes and First Nations were invited to complete the Food Policy Council Self-Assessment Tool (FPC-SAT). Structural equation modeling was used to test the FPC Framework. Three hundred and fifty-four FPC members from 95 councils completed the FPC-SAT. After slight modification, a revised FPC Framework was a good fit with the data (χ2 = 40.085, df = 24, p-value =.021, comparative fit index = 0.988, Tucker Lewis index = 0.982, root mean squared error of approximation = 0.044, p-close =.650). A moderation analysis revealed that community context influences the relationship between Social Capital and Council Effectiveness within the FPC Framework. The FPC Framework can guide capacity building interventions and FPC evaluations. The empirically tested framework can help FPCs efficiently work toward achieving their missions and improving their local food system

Food policy council case study describing cross-sector collaboration for food system change in a rural setting

Problem: Food Policy Councils (FPCs) are cross-sector collaborations that bring representatives from across the food system together to identify issues, coordinate programs, and inform policy. Little is known about how rural FPCs operate to influence food access in their communities. Purpose: To explore how a rural FPC facilitates cross-sector partnerships and influences food system change through interviews with eight members of the Adam’s County FPC. Results: Connections developed through the FPC helped council members work more effectively in their home organizations. Four themes were discussed: council dynamics and structure; sharing resources, expertise, and information; promoting healthy food access through programs; and food policy opportunities and challenges. Conclusions: This case study illustrates connections between FPC members in a rural county and identifies how FPCs can facilitate food system change in their communities. Improving our understanding of how rural FPCs function can help to advance the potential public health impact of councils

Nutrition-related policy and environmental strategies to prevent obesity in rural communities: A systematic review of the literature, 2002-2013

Introduction Residents of rural communities in the United States are at higher risk for obesity than their urban and suburban counterparts. Policy and environmental-change strategies supporting healthier dietary intake can prevent obesity and promote health equity. Evidence in support of these strategies is based largely on urban and suburban studies; little is known about use of these strategies in rural communities. The purpose of this review was to synthesize available evidence on the adaptation, implementation, and effectiveness of policy and environmental obesity-prevention strategies in rural settings. Methods The review was guided by a list of Centers for Disease Control and Prevention Recommended Community Strategies and Measurements to Prevent Obesity in the United States, commonly known as the COCOMO strategies. We searched PubMed, Cumulative Index of Nursing and Allied Health Literature, Public Affairs Information Service, and Cochrane databases for articles published from 2002 through 2013 that reported findings from research on nutrition-related policy and environmental strategies in rural communities in the United States and Canada. Two researchers independently abstracted data from each article, and resolved discrepancies by consensus. Results Of the 663 articles retrieved, 33 met inclusion criteria. The interventions most commonly focused on increasing access to more nutritious foods and beverages or decreasing access to less nutritious options. Rural adaptations included accommodating distance to food sources, tailoring to local food cultures, and building community partnerships. Conclusions Findings from this literature review provide guidance on adapting and implementing policy and environmental strategies in rural communities
