Translating Social Ecological Theory into Guidelines for Community Health Promotion

Health promotion programs often lack a clearly specified theoretical foundation or are based on narrowly conceived conceptual models. For example, lifestyle modification programs typically emphasize individually focused behavior change strategies, while neglecting the environmental underpinnings of health and illness. This article compares three distinct, yet complementary, theoretical perspectives on health promotion: behavioral change, environmental enhancement, and social ecological models. Key strengths and limitations of each perspective are examined, and core principles of social ecological theory are used to derive practical guidelines for designing and evaluating community health promotion programs. Directions for future health promotion research are discussed, including studies examining the role of intermediaries (e.g., corporate decision-makers, legislators) in promoting the well-being of others, and those evaluating the duration and scope of intervention outcomes.

The Science of Team Science Overview of the Field and Introduction to the Supplement

The science of team science encompasses an amalgam of conceptual and methodologic strategies aimed at understanding and enhancing the outcomes of large-scale collaborative research and training programs. This field has emerged rapidly in recent years, largely in response to growing concerns about the cost effectiveness of public- and private-sector investments in team-based science and training initiatives. The distinctive boundaries and substantive concerns of this field, however, have remained difficult to discern. An important challenge for the field is to characterize the science of team science more clearly in terms of its major theoretical, methodologic, and translational concerns. The articles in this supplement address this challenge, especially in the context of designing, implementing, and evaluating cross-disciplinary research initiatives. This introductory article summarizes the major goals and organizing themes of the supplement, draws links between the constituent articles, and identifies new areas of study within the science of team science.

Theoretical approaches to the promotion of physical activity: Forging a transdisciplinary paradigm

BACKGROUND Research in the physical activity promotion arena has focused on the application of theoretical perspectives aimed primarily at personal levels of understanding and analysis. The investigation of such theories has provided some insights related to potentially useful mediators of physical activity behavior. However, to continue to expand this field, new perspectives on personal-level theories, in addition to the exploration of more macro-level conceptual perspectives, are required. OBJECTIVE The purpose of this article is to: (1) briefly review the current strengths and limitations of the personal-level, physical activity-theory literature; and (2) introduce concepts and perspectives from other fields, including the social-ecology and urban-planning fields, of potential relevance to the physical activity arena. METHOD We provide an overview of potentially relevant theoretical perspectives aimed at different levels of understanding and analysis, from the personal level through the broader-scale meso- and macro-environmental perspectives. In addition, we suggest initial steps to take in developing a transdisciplinary paradigm encompassing all such levels of analysis and investigation. CONCLUSIONS Given the scope of the physical inactivity epidemic facing the U.S. population currently and in the future, methods and approaches that integrate theory and concepts across a broader group of disciplines will be increasingly necessary.

The Ecology of Team Science Understanding Contextual Influences on Transdisciplinary Collaboration

Increased public and private investments in large-scale team science initiatives over the past two decades have underscored the need to better understand how contextual factors influence the effectiveness of transdisciplinary scientific collaboration. Toward that goal, the findings from four distinct areas of research on team performance and collaboration are reviewed: (1) social psychological and management research on the effectiveness of teams in organizational and institutional settings; (2) studies of cyber-infrastructures (i.e., computer-based infrastructures) designed to support transdisciplinary collaboration across remote research sites; (3) investigations of community-based coalitions for health promotion; and (4) studies focusing directly on the antecedents, processes, and outcomes of scientific collaboration within transdisciplinary research centers and training programs. The empirical literature within these four domains reveals several contextual circumstances that either facilitate or hinder team performance and collaboration. A typology of contextual influences on transdisciplinary collaboration is proposed as a basis for deriving practical guidelines for designing, managing, and evaluating successful team science initiatives.

Evaluating transdisciplinary science.

The past two decades have seen a growing interest and investment in transdisciplinary research teams and centers. The Transdisciplinary Tobacco Use Research Centers (TTURCs) exemplify large-scale scientific collaborations undertaken for the explicit purpose of promoting novel conceptual and methodological integrations bridging two or more fields. Until recently, few efforts have been made to evaluate the collaborative processes, and the scientific and public policy outcomes, of such centers. This manuscript offers a conceptual framework for understanding and evaluating transdisciplinary science and describes two ongoing evaluation studies covering the initial phase of the TTURC initiative. The methods and measures used by these studies are described, and early evaluative findings from the first 4 years of the initiative are presented. These data reveal progress toward intellectual integration within and between several of the TTURCs, and cumulative changes in the collaborative behaviors and values of participants over the course of the initiative. The data also suggest that different centers may follow alternative pathways toward transdisciplinary integration and highlight certain environmental, organizational, and institutional factors that influence each centers readiness for collaboration. Methodological challenges posed by the complexities of evaluating large-scale scientific collaborations (including those that specifically aspire toward transdisciplinary integrations spanning multiple fields) are discussed. Finally, new directions for future evaluative studies of transdisciplinary scientific collaboration, both within and beyond the field of tobacco science, are described.

Objective and subjective dimensions of travel impedance as determinants of commuting stress.

The stressful characteristics of commuting constraints are conceptualized in terms of both physical and perceptual conditions of travel impedance. This study develops and operationalizes the concept of subjective impedance, as a complement to our previously developed concept of impedance as a physically defined condition of commuting stress. The stress impacts of high-impedance commuting were examined in a study of 79 employees of two companies in the follow-up testing of a longitudinal study. Subjective impedance was overlapping but not isomorphic with physical impedance, and these two dimensions have differential relationships with health and well-being outcomes. The physical impedance construct received further confirmation in validational analyses and in predicted effects on various illness measures and job satisfaction. The newly constructed subjective impedance index was significantly related to evening home mood, residential satisfaction, and chest pain. Job change was also influenced primarily by commuting satisfaction. The results are discussed within an ecological framework emphasizing interdomain transfer effects and situational moderators of commuting stress.

The Experience of Crowding in Primary and Secondary Environments

The behavioral effects of density have been documented most clearly and consistently in studies involving nonhumans. It is well established that the prolonged exposure of animal communities to conditions of high density eventuates in social disorganization and a variety of physiological anomalies (Calhoun, 1962; Christian, Flyger, and Davis, 1960; Davis, 1971; Thiessen and Rodgers, 1961). In general, the animal research portrays density as a stressor variable which places severe constraints on important social activities, such as allocation of

A social psychological model of human crowding phenomena

Abstract Previous research on crowding has generally lacked a theoretical perspective. Moreover, there has been a tendency to view crowding in terms of spatial considerations alone and a failure to distinguish between the physical condition (density) and the psychological experience (crowding). In the present discussion, a heuristic model of human crowding phenomena is proposed which permits an integration of various theoretical perspectives and the derivation of experimental hypotheses. Although the limitation of space remains as the essential ingredient of crowding, the proposed model introduces personal and social variables which have a direct bearing on a persons perception of spatial restriction as well as on his attempts to cope with this constraint. The relation between the dimensions of the model is examined in terms of social-psychological theory. Finally, a program for future research is discussed.

A Multi-Level Systems Perspective for the Science of Team Science

Understanding how teams function is vital because they are increasingly dominating the production of high-impact science. This Commentary describes recent research progress and professional developments in the study of scientific teamwork, an area of inquiry termed the “science of team science” (SciTS, pronounced “sahyts”). It proposes a systems perspective that incorporates a mixed-methods approach to SciTS that is commensurate with the conceptual, methodological, and translational complexities addressed within the SciTS field. The theoretically grounded and practically useful framework is intended to integrate existing and future lines of SciTS research to facilitate the field’s evolution as it addresses key challenges spanning macro, meso, and micro levels of analysis.

Increasing the health promotive capacity of human environments.

This article offers an integration of two different perspectives on health promotion research and practice: one emphasizing the concept of community capacity for health improvement and the other focusing on the notion of health supportive environments. These two approaches generally have emphasized different kinds of community assets for health promotion. Specifically, community capacity research has focused on the cultivation of human resources (e.g., collaborative coalitions, participatory decision-making, health education strategies) for health promotion, whereas environmentally oriented research has underscored the influence of material resources (e.g., the built environment, natural resources, technological infrastructure) on important health behaviors and outcomes. Combining these two streams of health promotion research yields a broader understanding of the health promotive capacity of human environments and suggests several “best process” guidelines for enhancing health promotion practice.
