Public health asks of systems science: to advance our evidence-based practice, can you help us get more practice-based evidence?

Public health asks of systems science, as it did of sociology 40 years ago, that it help us unravel the complexity of causal forces in our varied populations and the ecologically layered community and societal circumstances of public health practice. We seek a more evidence-based public health practice, but too much of our evidence comes from artificially controlled research that does not fit the realities of practice. What can we learn from our experience with sociology in the past that might guide us in drawing effectively on systems science?

Inferring strategies for disseminating physical activity policies, programs, and practices from the successes of tobacco control.

Efforts at reducing tobacco use in the United States and Canada over the last half century have been amazingly successful. This article examines those efforts in order to identify policies, programs, and practices found useful in tobacco control that might be usefully disseminated to world populations to improve rates of physical activity. Tobacco-control activities began with efforts to influence the individual smoker through public education and counter-advertising. Increasing awareness of the addictive properties of tobacco, industry efforts to manipulate those properties, and to target youth with aggressive advertising, fueled public outrage that supported additional policy changes to include community interventions, legal actions, and restraints against the tobacco industry. The article first examines ways to view the process of transferring knowledge from one enterprise (reducing tobacco consumption) to another (increasing physical activity). Several theories of knowledge generalization and dissemination are explored: transfer, knowledge utilization, application, diffusion, and implementation. The second section identifies the dissemination of tobacco control by means of brief health behavior-change interventions for smoking cessation that have been successfully integrated into primary clinical care. The question of whether similar strategies can be successfully disseminated to increase physical activity is examined in detail. The article then moves on to look at the success of arguably the most successful program in the world at achieving a reduction in tobacco control-the State of California. Finally, we compare and contrast some of the lessons as they have played out in another national context-Canada. In the concluding section, some lessons are identified that we believe may be successfully utilized in societal attempts to increase physical activity in world populations.

Evaluating the relevance, generalization, and applicability of research: issues in external validation and translation methodology.

Starting with the proposition that "if we want more evidence-based practice, we need more practice-based evidence," this article (a) offers questions and guides that practitioners, program planners, and policy makers can use to determine the applicability of evidence to situations and populations other than those in which the evidence was produced (generalizability), (b) suggests criteria that reviewers can use to evaluate external validity and potential for generalization, and (c) recommends procedures that practitioners and program planners can use to adapt evidence-based interventions and integrate them with evidence on the population and setting characteristics, theory, and experience into locally appropriate programs. The development and application in tandem of such questions, guides, criteria, and procedures can be a step toward increasing the relevance of research for decision making and should support the creation and reporting of more practice-based research having high external validity.

The public health infrastructure and our nation's health.

Threats to Americans' health-including chronic disease, emerging infectious disease, and bioterrorism-are present and growing, and the public health system is responsible for addressing these challenges. Public health systems in the United States are built on an infrastructure of workforce, information systems, and organizational capacity; in each of these areas, however, serious deficits have been well documented. Here we draw on two 2003 Institute of Medicine reports and present evidence for current threats and the weakness of our public health infrastructure. We describe major initiatives to systematically assess, invest in, rebuild, and evaluate workforce competency, information systems, and organizational capacity through public policy making, practical initiatives, and practice-oriented research. These initiatives are based on applied science and a shared federal-state approach to public accountability. We conclude that a newly strengthened public health infrastructure must be sustained in the future through a balancing of the values inherent in the federal system.

Community outreach: from measuring the difference to making a difference with health information.

BACKGROUND: Community-based outreach seeks to move libraries beyond their traditional institutional boundaries to improve both access to and effectiveness of health information. The evaluation of such outreach needs to involve the community in assessing the program's process and outcomes. PURPOSE: Evaluation of community-based library outreach programs benefits from a participatory approach. To explain this premise of the paper, three components of evaluation theory are paired with relevant participatory strategies. CONCEPTS: The first component of evaluation theory is also a standard of program evaluation: use. Evaluation is intended to be useful for stakeholders to make decisions. A useful evaluation is credible, timely, and of adequate scope. Participatory approaches to increase use of evaluation findings include engaging end users early in planning the program itself and in deciding on the outcomes of the evaluation. A second component of evaluation theory seeks to understand what is being evaluated, such as specific aspects of outreach programs. A transparent understanding of the ways outreach achieves intended goals, its activities and linkages, and the context in which it operates precedes any attempt to measure it. Participatory approaches to evaluating outreach include having end users, such as health practitioners in other community-based organizations, identify what components of the outreach program are most important to their work. A third component of evaluation theory is concerned with the process by which value is placed on outreach. What will count as outreach success or failure? Who decides? Participatory approaches to valuing include assuring end-user representation in the formulation of evaluation questions and in the interpretation of evaluation results. CONCLUSIONS: The evaluation of community-based outreach is a complex process that is not made easier by a participatory approach. Nevertheless, a participatory approach is more likely to make the evaluation findings useful, ensure that program knowledge is shared, and make outreach valuing transparent.

Participatory research and evaluation: from best practices for all states to achievable practices within each state in the context of the Master Settlement Agreement.

Because the Centers for Disease Control and Prevention (CDC) already assisted state tobacco control initiatives, many state health departments turned to CDC for guidance on how to use Master Settlement Agreement monies. This article describes how CDC funded participatory research to establish local evidence and provided technical assistance for participatory program evaluation. The article (a) presents a telephone interview study of principal investigators (PIs) to determine how CDC could best facilitate participatory research and (b) identifies factors CDC considered to devise evaluation technical assistance that reflected local context. The interview study identified 8 areas where PIs needed CDC's support to undertake participatory research: continuity, timeliness, flexibility, clear and explicit expectations, appropriate and instructive accountability, creation of a vision for participatory research, tailored technical assistance, and enhancement of partner collaboration and support. These findings are being used to inform CDC's research funding. Meanwhile, user-driven technical assistance for participatory evaluation is being accessed by many states.

Possible lessons from the tobacco experience for obesity control.

Although obesity is increasing to epidemic proportions in many developed countries, some of these same countries are reporting substantial reductions in tobacco use. Unlike tobacco, food and physical activity are essential to life. Yet similar psychological, social, and environmental factors as well as advertising pressures influence the usage patterns of all 3. These similarities suggest that there may be commonalities between factors involved in controlling obesity and tobacco. This review, therefore, seeks to draw lessons from the tobacco experience for the organization of more successful obesity control. Smoking cessation counseling by physicians has been found to be one of the most clinically effective and cost-effective of all disease prevention interventions. When used alone, however, it cannot decrease the cultural acceptability of tobacco and the pressures and cues to smoke. Research and evaluation have shown the key elements of tobacco control to be (1) clinical intervention and management, (2) educational strategies, (3) regulatory efforts, (4) economic approaches, and (5) the combination of all of these into comprehensive programs that address multiple facets of the environment simultaneously. For each element, we present the evidence outlining its importance for tobacco control, discuss its application to date in obesity control, and suggest areas for further research. Viewing all of the elements involved and recognizing their synergistic effects draws researchers and practitioners back from an exclusive concentration on their particular setting to consider how they might seek to influence other settings in which individuals and populations must negotiate desired changes in nutrition and physical activity.

Assessment of communication barriers in community pharmacies.

This study identified previously reported facilitators and barriers to pharmacist-client communication and then evaluated their impact on the observed communication behaviors of pharmacists. Pharmacists (n = 100) completed a seven-page questionnaire collecting information on 11 variables that had been organized according to the Policy, Regulatory and Organizational Constructs in Educational and Ecological Development (PROCEDE) model as predisposing, enabling, or reinforcing of pharmacist communication with their clients. Demographic variables also were included. "Communication quality" served as the study's dependent variable, whereas pharmacist responses served as the independent variables. Communication quality scores for each pharmacist were obtained from the analysis of 765 audiorecordings of verbal exchanges occurring between the study pharmacists and their consenting clients during 4-hour, on-site observation periods. Four of the variables examined in the study were found to share a unique relationship with communication quality (pharmacists' attitude, year of graduation, adherence expectations, and outcome expectations). Hierarchical multiple regression analysis revealed that the variables measured in the questionnaire accounted for 23% of the variance in communication quality scores. Plausible explanations for why the study was unable to capture more of the variance in its proposed relationships and future areas for research are provided.

Empowerment as fostering positive youth development and citizenship.

OBJECTIVE: To develop a theoretical framework of youth empowerment in the context of a participatory community health promotion intervention, a longitudinal qualitative study was conducted. METHODS: Individual and group interviews, documents, and observations were analyzed using the constant comparative method and theoretical sampling. RESULTS: Practitioners created an environment conducive to adolescents' taking responsibility for their quality-of-life issues by welcoming and enabling youth. Power was transferred to youth as responsibility for voicing, decision making, and action. This led to positive changes in youth development and their social integration into community. CONCLUSION: Empowerment emerged as a transactional partnering process between adults and youth.

An integrative framework for community partnering to translate theory into effective health promotion strategy.

INTRODUCTION: Although there is general agreement about the complex interplay among individual-, family-, organizational-, and community-level factors as they influence health outcomes, there is still a gap between health promotion research and practice. The authors suggest that a disjuncture exists between the multiple theories and models of health promotion and the practitioner's need for a more unified set of guidelines for comprehensive planning of programs. Therefore, we put forward in this paper an idea toward closing the gap between research and practice, a case for developing an overarching framework--with several health promotion models that could integrate existing theories--and applying it to comprehensive health promotion strategy. AN INTEGRATIVE FRAMEWORK: We outline a theoretical foundation for future health promotion research and practice that integrates four models: the social ecology; the Life Course Health Development; the Predisposing, Reinforcing, and Enabling Constructs in Educational/Environmental Diagnosis and Evaluation-Policy, Regulatory and Organizational Constructs in Educational and Environmental Development; and the community partnering models. The first three models are well developed and complementary. There is little consensus on the latter model, community partnering. However, we suggest that such a model is a vital part of an overall framework, and we present an approach to reconciling theoretical tensions among researchers and practitioners involved in community health promotion. INTEGRATING THE MODELS: THE NEED FOR SYSTEMS THEORY AND THINKING: Systems theory has been relatively ignored both by the health promotion field and, more generally, by the health services. We make a case for greater use of systems theory in the development of an overall framework, both to improve integration and to incorporate key concepts from the diverse systems literatures of other disciplines. VISION FOR HEALTHY COMMUNITIES: (1) Researchers and practitioners understand the complex interplay among individual-, family-, organizational-, and community-level factors as they influence population health; (2) health promotion researchers and practitioners collaborate effectively with others in the community to create integrated strategies that work as a system to address a wide array of health-related factors; (3) The Healthy People Objectives for the Nation includes balanced indicators to reflect health promotion realities and research-measures effects on all levels; (4) the gap between community health promotion "best practices" guidelines and the way things work in the everyday world of health promotion practice has been substantially closed. CONCLUSIONS AND RECOMMENDATIONS: We suggest critical next steps toward closing the gap between health promotion research and practice: investing in networks that promote, support, and sustain ongoing dialogue and sharing of experience; finding common ground in an approach to community partnering; and gaining consensus on the proposed integrating framework.
