Public Health Ecological Approaches
by
Monica L. Wendel, Kenneth R. McLeroy

Introduction

Social ecology provides a framework for understanding how individuals and their social environments mutually affect each other across the lifespan. Drawing from the ideas of Kurt Lewin’s A Dynamic Theory of Personality: Selected Papers (New York: McGraw-Hill, 1935), which conceptualized this relationship as an equation that yielded behavior, Urie Bronfenbrenner’s The Ecology of Human Development (Bronfenbrenner 1979, cited under History) extended the social ecological perspective to account for the complexity of individuals developing within embedded systems. Bronfenbrenner specified micro-, meso-, exo-, and macro- subsystems, which constitute the settings and life space within which an individual develops. In this model, each of the subsystems influences the individual and the other subsystems. Moreover, Brofenbrenner viewed the individual as moving through time and being influenced by his or her developmental and life course experiences (ontogenic development). McLeroy, et al. 1988 (cited under History), which appeared in Health Education Quarterly as “An Ecological Perspective on Health Promotion Programs,” further defined the social ecological model for health promotion to depict interrelated systems at the intrapersonal, interpersonal, organizational, community, and policy levels, illustrated as concentric circles. The authors subsequently add other levels of analysis, including the physical environment and culture. The social ecological model provides a framework for understanding the factors that produce and maintain health and health-related issues, allowing identification of promising points of intervention and understanding how social problems are produced and sustained within and across the various subsystems. However, the model has also yielded a growing acknowledgment of the complexity of these systems, highlighting the need for more sophisticated intervention and research methods. Social ecological concepts are now widely used within the field of public health and are included in: (1) core competencies for public health developed by the Association of Schools of Public Health that serve as the basis for the public health certification examination; (2) a framework for several of the leading volumes on theory and practice in the field; (3) curricular frameworks for a number of the schools and programs for public health; and (4) other, related frameworks, such as the model proposed for the National Institutes of Health population disparities centers.

History

Much of the research at the foundation of current thinking in social ecology stems from human development, and ecological, community, and health psychology. The works in this section provide a glimpse of the conceptual underpinnings of the social ecological perspective in public health. Bronfenbrenner 1979 extends previous ideas about the interrelation between individuals and their environments, applying an ecological framework to human development. Here, the author lays out the embedded systems in which human behaviors occur: the micro-, meso-, exo-, and macro-systems, and the 2005 volume extends Bronfenbrenner’s ecological framework to include a greater emphasis on systems thinking and systems ideas. The history of the social ecological perspective in public health stems from synthesis of ideas from other disciplines including the author’s early works on human development. McLeroy, et al. 1988 is often cited as one of the initial articles specifically applying an ecological model to public health and health promotion. Winett, et al. 1989 provides an ecological perspective on health psychology and public health with a particular focus on several problem areas, including adolescent pregnancy, dietary change, mental health, and others. Moos 1979 focuses increased attention on the role of the physical environment, environmental psychology, and the influences on human behavior of the natural and constructed environment. Susser and Susser 1996 describes the application of a social ecological perspective to the discipline of epidemiology, likening the multiple levels to nested Chinese boxes. Bronfenbrenner 2005 extends the author’s social ecological model to a bioecological theory of human development and explicates its fit with systems theory.

    A thorough explication of the rationale for the systems model in human development with an emphasis on the connection between person and setting (environment). Although historical, when presented, Bronfenbrenner’s theoretical perspective was new in its application. Provides easily understood examples for each theoretical step.

    A brief discussion historical paradigms and paradigm shifts in epidemiology, highlighting the need to attend to social processes that influence this distribution of disease. Provides a rationale for an ecological perspective as a systematic rather than universalistic paradigm. Presents a concise table of eras in epidemiology with their preventive and analytic approaches.

    This volume provides a rapprochement of health psychology and public health through an ecological perspective and applies an ecological perspective to HIV, community health promotion, mental health, teen pregnancy, diet, health in the workplace, environmental health, and aging. Well written and a valuable resource for the application of social ecological concepts.
