Increased emphasis on community collaboration indicates the need for consensus regarding the definition of community within public health. This study examined whether members of diverse US communities described community in similar ways. To identify strategies to support community collaboration in HIV vaccine trials, qualitative interviews were conducted with 25 African Americans in Durham, NC; 26 gay men in San Francisco, Calif; 25 injection drug users in Philadelphia, Pa; and 42 HIV vaccine researchers across the United States. Verbatim responses to the question "What does the word community mean to you?" were analyzed. Cluster analysis was used to identify similarities in the way community was described. A common definition of community emerged as a group of people with diverse characteristics who are linked by social ties, share common perspectives, and engage in joint action in geographical locations or settings. The participants differed in the emphasis they placed on particular elements of the definition. Community was defined similarly but experienced differently by people with diverse backgrounds. These results parallel similar social science findings and confirm the viability of a common definition for participatory public health.
PUBLIC HEALTH PROGRAMS and policy are often defined at regional and national levels, but community is, literally, where prevention and intervention take place. Community context has been identified as an important determinant of health outcomes.1 Recognition of these facts has led to increased calls for community collaboration as an important strategy for successful public health research and programs.29 Reviews of the effectiveness of collaborations for improving community health indicate that they can be effective911 but that there are many potential obstacles to realizing the benefits of a participatory approach in both public health research and programs.8,1115 In particular, the lack of an accepted definition of community can result in different collaborators forming contradictory or incompatible assumptions about community and can undermine our ability to evaluate the contribution of community collaborations to achievement of public health objectives.9,16 We are more likely to validate the effectiveness, or ineffectiveness, of collaborative models if we can identify core dimensions of community that have external validity across communities, are consistent with measures that have internal validity within diverse communities, and have predictive value for community-level health outcomes. Efforts to develop and test HIV vaccines have highlighted social challenges that make community support, trust, and involvement critical for the long-term success of preventive HIV vaccines.17 Project LinCS (Linking Communities and Scientists) was undertaken to identify effective strategies for meeting these challenges. HIV vaccine efficacy trials and, ultimately, immunization programs require national coordination across diverse communities. The primary Project LinCS research objective centered on identifying ways to make efforts such as large-scale efficacy trials and immunization programs as participatory as possible. A related objective was to demonstrate the value added to research when community members actively participate in the design, implementation, and interpretation of the research. For this commentary, we analyzed data from 1 component of Project LinCS that asked people how they defined community. The interviews were conducted with diverse groups, thus allowing us to look at the potential effect of local and historic experience on the way people defined community and to determine whether a single definition of community could effectively encompass the diversity of local experience.
Data Collection Project LinCS participants included African Americans in Durham, NC; gay men in San Francisco, Calif; injection drug users (IDUs) in Philadelphia, Pa; and HIV vaccine researchers in locations across the United States. The 3 local research communities were selected through a competitive funding process. Through a study design collaboratively developed by researchers and local community advisory boards convened for the project, a total of 76 face-to-face, in-depth, open-ended interviews were conducted in Philadelphia, Durham, and San Francisco to identify broad issues, including how people defined community. The interviews were conducted between December 1995 and May 1996. Another 42 in-depth interviews were conducted between September 1997 and September 1998 via telephone with HIV vaccine researchers across the United States; these interviews included a parallel question on defining community. Study protocols and interview guides were approved by local and Centers for Disease Control and Prevention institutional review boards; written informed consent was obtained from all participants (the vaccine researchers mailed back signed consent forms before their interviews). Interviews were tape-recorded, transcribed into computer text files, and coded by interview question. Verbatim responses to the following question were then extracted for analysis: "The word community means different things to different people. What does the word community mean to you? What is a community?"
Data Analysis
To minimize the possibility that relevant text was missed, all text was double-coded. Intercoder agreement for text associated with each participant group was then assessed for each code by For each participant, numeric listings summarized whether or not each code was applied to that person's text. Numeric matrices were then generated to summarize which codes occurred together in the text of all persons within each participant group. From the matrices, complete-link Johnson's hierarchical clusters were generated in ANTHROPAC21 to identify core elements used to define community. The cluster analysis helped identify similarities in the way people defined community and the extent to which those similarities cut across participant groups.
The 4 participant groups varied in terms of a number of sociodemographic characteristics beyond those immediately reflective of the intentional targeted sampling. Participants who were scientists or from San Francisco tended to have higher levels of education and higher incomes than participants in Philadelphia and Durham. None of the scientists and only 1 of the Philadelphia participants lacked health insurance, although they differed in terms of the primary source of insurance (employer based for scientists and government based for IDUs). Approximately one third of San Francisco and Durham participants lacked health insurance. The mean number of years lived in the current neighborhood of residence was longest for IDUs in Philadelphia (16.5 years), followed by scientists (7.2), African Americans in Durham (5.7), and gay men in San Francisco (2.6).
Of the 118 participants interviewed, 113 provided definitions of community (the question was omitted in interviews with 3 participants in Durham and 2 in San Francisco). Coding identified 17 distinct themes or elements that appeared in the definitions of 2 or more respondents (Table 1
The third and fourth clusters centered on elements that reflected stresses experienced by communities or their members. The first stress cluster included the elements of criminality and drug use. The second centered on the elements of AIDS and unity.
Core Elements of Community
Locus: a sense of place. Locus encompassed the idea of community as something that could be located and described, denoting a sense of place, locale, or boundaries. One can be "in" a community physically whether or not one identified as being a member of the community. People referred to locus in terms of specific areas (neighborhood, corner, block; street, road, highway; zip code area; village, city, county), with reference to specific settings (home, household; workplace; local taproom or bar, corner grocery store, newsstand, sandwich shop, bookstore; community building, swimming pool, recreation center; church, school), and in terms of general locations (an area or place where people live together; environment or surroundings). Sharing: common interests and perspectives. Sharing referred to the existence of shared perspectives and common interests that contributed to a sense of community. Community members were described as sharing the following: Values, norms, mind-set, viewpoint, ideology, beliefs, visions Passions, obsessions, interests, likes and dislikes, opinions, concerns Activities, goals, objectives Symbols, jargon Skin color, sexual identity Tribulations, oppression, repression, history Sharing contributed to a sense of community through the following: Common issues, threads, beliefs, factors Being in tune with each other Comfort, familiarity, togetherness, identity, recognition Joint action: a source of cohesion and identity. Joint action was described as a source of community cohesion and identity. A conscious intent to generate community through action was not viewed as necessary; rather, joint action was seen as leading naturally to the creation of community. Community was described as emerging from the joint actions of people who did the following: Socialize, hang out, converse, intermingle, gossip, "shoot the shit" Work at the polls, volunteer at the library, run phone banks, train people, work on projects Keep people informed about resources, services, and what's happening Paint houses; paint the street; push brooms; shovel snow; keep up the area; clean up the block, neighborhood, yard, or house; have block parties Give food, share resources, provide for neighbors in need Watch over, check up on, look out for, keep an eye on each other Set values and goals for the children, have their butts kicked a little bit if they're slacking off, push for the betterment of everyone, do something positive, improve the neighborhood Get together, do things together, work together, act together, participate, plan, get things done, get inspired, engage in activities, give input, accomplish goals Write, speak, educate, encourage, pray Social ties: the foundation for community. Social ties were described in terms of interpersonal relationships that formed the foundation for community. In some instances, such relationships were described as requiring little, if any, effort or ongoing acknowledgment on the part of the individual. The types of relationships cited included the following: family, parents, siblings, cousins; roommates, household; lovers, partners; friends, neighbors, associates, coworkers, acquaintances; role models, support groups. In addition, participants often described characteristics that they associated with community-based relationships or people. Community, participants said, meant ties with people Whom they can trust With whom they feel comfortable Who care about each other With whom they interact, hang out, choose to be sociable, spend time, connect Who are known to them Whom they always see in the background or around them With whom they grew up Diversity: social complexity within communities. Diversity emerged in discussions of social complexity (e.g., communities within communities, stratification, interwoven groups, hidden communities, or multiple levels of community). As used here, diversity excluded culturally based ethnic distinctions (see the discussion of pluralism below). Discussions of diversity focused on a larger societal view of community and made reference to differences in interpersonal interaction that resulted from the following: Different levels of interaction between people, from the intimate to the superficial Demographic and social diversity in the form of race, ethnic origin, socioeconomic status, sexuality, drug use, profession The presence of specialized groups that performed needed tasks, such as activists and service providers The presence of groups that identified with overlapping or multiple communities The presence of groups that were disowned, stigmatized, stereotyped, or distrusted within communities
As seen in Figure 1A
Despite group differences in the saliency, frequency, and co-occurrence of the 5 core elements, the overall response pattern indicates that these 5 elements were universally recognized within each community as a whole, if not by every community member. In anthropologic terms, the elements constitute a common cultural domain.22,23 Together, they suggest a full definition of community as a group of people with diverse characteristics who are linked by social ties, share common perspectives, and engage in joint action in geographic locations or settings.
Group-Based Elements of Community
Divisiveness referred to descriptions of community fragmentation or a lack of unity, often expressed as an overemphasis on individualism and self-interest, or as attitudes that hindered unity and cooperation. Divisiveness was often discussed in the context of the need for or a perceived lack of responsibility on the part of community members. Discussions of leverage centered on the potential ways that groups or individuals can bring about positive or negative consequences for the community as a whole. Pluralism referred to discussions of the maintenance of distinctions between coexisting ethnic groups. Unlike the core element of diversity, which focused on variability in a wide range of individual-level characteristics, pluralism implied ethnic and cultural distinctions among people living in the same area. Cultural pluralism is an anthropologic concept defined as "social and political interaction within the same society of people with different ways of living and thinking."24(p658) The challenges of living in a pluralistic community were described primarily by African American, Latino, and Asian/Pacific Islander gay men in San Francisco who attempted to navigate simultaneously among problems related to their ethnicity (e.g., racism, restrictive immigration laws) and those related to their sexual identity (e.g., homophobia, rejection by family members). Responsibility was discussed in terms of the way people were or should be responsible for their own behavior, including how their behavior reflected on or affected the community as a whole. As such, leverage and responsibility were often discussed together.
The Impact of Stress on a Community
Statements that community was nonexistent were made by 6 respondents from Philadelphia and 3 from San Francisco. These discussions often included statements about diversity or pluralism as an obstacle to the development of community, by contributing to a lack of common identity or undermining a sense of responsibility to the group. For the Philadelphia drug users, the lack of community was sometimes seen as pervasive, or the drug culture was viewed as a noncommunity that was both separate from and surrounded by a functional local community that included the elements of locus, action, ties, and sharing.
The Elements of Community Collectively, the Project LinCS participants described community by using a limited set of elements that reflect concepts previously noted in the social science literature. Four of the core community elements identified here through empiric meanslocus, sharing, joint action, and social tiesare commonly found in social science definitions of community. In an early literature review of 94 definitions, Hillery25 found that two thirds cited social interaction, geographic area, and common ties as essential elements of community life, and almost three fourths cited area and social interaction. A review of an additional 60 definitions subsequently published in the social science literature found little change beyond a slight increase in emphasis on "people with common ties residing in a common geographic area."26 Taking a different approach, McKeown and colleagues27 analyzed the way community was conceptualized in 4 classic ethnographic studies conducted by 2 anthropologists at different stages in their careers. They noted overall agreement in the use of 4 basic attributes to describe community: locality, biological and social membership, common institutions, and shared actions. From a psychological perspective and using an empiric approach that parallels our own, Chavis and colleagues28 identified 4 elements composing a sense of community: membership, influence, integration and fulfillment of needs, and shared emotional connection. Using data from a study in a suburb of Toronto, Wellman and Wortley29 argued that locus was of decreasing importance for urban communities and that these were best described in terms of "personal community networks" that are socially diverse in composition, spatially dispersed, and sparsely knit. Others have suggested that the decreasing importance of locus actually leads to a sense of the loss of community. For example, Glynn30 evaluated the relationship between people's ideal sense of community and their perception of their actual community in 3 diverse settings (an Israeli kibbutz and 2 dissimilar cities in Maryland) and found that neighborhood identification was important for the development of an actual sense of community. Patrick and Wickizer9 reviewed social science definitions of community with an eye toward developing and implementing effective community-level health interventions. They identified 3 broad conceptual approaches to the definition of community: those that defined community as place, as social interaction, and as social and political responsibility. The concept of social and political responsibility is similar to our core element of joint action, combined with our group-based elements. Patrick and Wickizer9(p51) offered a working definition of community as "the entire complex of social relationships in a given locale, and their dynamic interaction and evolution in working toward [the] solution of health problems." The importance of local diversity has not been previously articulated in definitions of community, although the effect of such diversity on health measures has been noted. For example, Sampson and colleagues31 pointed to the need to explore the meaning and sources of variation within neighborhoods or local communities for collective efficacy for children. Zakus and Lysack16 noted that communities are rarely, if ever, a homogeneous whole and that this represents a major challenge for successful community participation in setting health policy. The fact that diversity emerged as a core element in our empiric exploration of definitions of community was driven to a great extent by the experiences of the gay men who were interviewed. San Francisco is a national and international meeting ground for gay men. The interviews we conducted suggest that many of them are consciously seeking to build a community based on a positive valuing of unity, diversity, and cultural pluralism. With increased mobility and immigration throughout the United States, the importance of diversity for community structure and function is likely to increase in other locations and for other populations. The challenges presented by local diversity, in turn, are likely to become increasingly important for public health efforts as well.
Implications of the Experience of Community for Collaboration The profiles for Durham and Philadelphia also had a surface resemblance to each other. In contrast with San Francisco participants and the scientists, Durham and Philadelphia participants viewed locus as the principal element of community. This was especially true for IDUs in Philadelphia. Both groups emphasized the importance of joint action and social ties, while minimally discussing the role of diversity. African American participants in Durham included more college-educated and nonheterosexual individuals than did Philadelphia participants and, perhaps as a result, were somewhat more likely to discuss the role of shared perspectives for community than were Philadelphia participants. In both Durham and Philadelphia, most people described community as a "given" in their immediate environment. However, for IDUs, the given community environment was less likely to be described as supportive than for African Americans in Durham. These differences in the way people perceived and talked about the core elements of community suggest the need for multiple models of collaboration for public health research and programs. In fact, the collaborations we established in San Francisco, Durham, and Philadelphia illustrate this need. At each site, researchers worked with a community advisory board (CAB), but in different ways.
The San Francisco collaboration.
The Durham collaboration.
The Philadelphia collaboration.
The Role of Community Representation for Collaboration If collaboration is to be an effective component of public health research and programs, it will require a greater understanding of the way people interact individually and as groups. The definition of community provided in this commentary supplies a potential framework for investigating such interactions. Each of the core elements composing community (locus, sharing, joint action, social ties, and diversity) can be evaluated relative to public health outcomes through existing social science models, including social network analysis,3537 sense of community,3842 social capital,43,44 cultural domain analysis,22,23,45,46 and geographic information systems.47 Such models provide a solid foundation for a systematic approach to community-level and community-based public health research and programs.
The results of our analysis point to a core definition of community as a group of people with diverse characteristics who are linked by social ties, share common perspectives, and engage in joint action in geographical locations or settings. Our results further suggest that a cookbook approach to participatory programs and research will not work because the experience of community differs from one setting to another. Rather, each research collaboration, and each level of collaboration from the local to the national and the international, must reconcile the differences and similarities among the participating communities. Community collaboration in public health programs and research presents many challenges, in part because community has been defined in ambiguous and contradictory ways. Despite important differences in the experience of community, our study suggests that people largely agree about what community is. The empiric evidence, in turn, is bolstered by established social science theory. Additionally, existing social science tools provide a strong foundation for measuring and evaluating the contributions of community collaboration to the achievement of public health objectives. Thus, a sound empiric and theoretic basis exists for achieving consensus on a definition of community for public health. Consensus will facilitate the systematic comparison of local populations by directing attention to a set of core elements for measurement. Systematic comparison, in turn, will facilitate hypothesis testing and strengthen the scientific study of the role of community in public health. For example, it could help us identify functional thresholds for the core elements, such that groups above the threshold are significantly more likely to experience beneficial health outcomes than those below the threshold. In other words, it can help us understand how to build and support "good" communities that enhance the health of their members. It can help us understand which characteristics or combinations of characteristics are necessary or sufficient for supporting intermediate goals such as the sustainability of prevention programs or the diffusion of beneficial health practices. And it can provide a sound theoretic basis for building successful community collaborations in public health through the systematic evaluation of who participates, why they participate, what they share, what they do, and how participants are connected to each other and to their constituencies.
