Assessing environmental assets for health promotion program planning: a practical framework for health promotion practitioners

Conducting a health needs assessment is an important if not essential first step for health promotion planning. This paper explores how health needs assessments may be further strengthened for health promotion planning via an assessment of environmental assets rooted in the multiple environments (policy, information, social and physical environments) that shape health and behavior. Guided by a behavioral-ecological perspective- one that seeks to identify environmental assets that can influence health behavior, and an implementation science perspective- one that seeks to interweave health promotion strategies into existing environmental assets, we present a basic framework for assessing environmental assets and review examples from the literature to illustrate the incorporation of environmental assets into health program design. Health promotion practitioners and researchers implicitly identify and apply environmental assets in the design and implementation of health promotion interventions;this paper provides foundation for greater intentionality in assessing environmental assets for health promotion planning.


Introduction
In planning health promotion interventions, conducting a health needs assessment is an important if not essential first step. [1][2][3][4] While the reasons for conducting a health needs assessment vary-from identifying and prioritizing health needs and population groups most at risk as part of a community health assessment (CHA) or community health needs assessment (CHNA), [2][3][4] to designing a health intervention to address a specific health problem for a given population, 1 to other reasons such as policy development, public health assurance (e.g., enforcement of sanitary codes), and community engagement, 2,3 central to current health needs assessment approaches has been a focus on assessing both the health needs as well as the assets or resources of a given community. This combined focus on needs and assets is reflected in current definitions of CHAs and CHNAs 2 and reflects the WHO Health Promotion Glossary's general definition of health needs assess-ment as "a systematic procedure for determining the nature and extent of health needs in a population, the causes and contributing factors to those needs, and the human, organizational and community resources which are available to respond to these. " 5 The incorporation of an asset assessment holds great potential to enhance the health needs assessment process as well as program efficacy and sustainability, and as such, merits increased attention in the field of health promotion planning. The movement toward an asset-based assessment approach was spearheaded in part by Kretzman and McKnight's 6 seminal work on asset mapping in the field of community organizing, which reframed community assessment from a deficit approach focused purely on needs of a community, to an approach and philosophy that promotes harnessing existing local resources and capacities for community development. An asset-based approach to community development includes identifying individ-ual-level assets such as skills, talents and knowledge of people within a given community; organizational assets existing within the community such as community associations, local businesses, and religious organizations; organizational assets controlled from outside of the community, such as hospitals, schools and financial institutions; and physical resources such as land use. 7 In the field of health promotion, a similar movement toward an asset-based approach took place during the same period of the 1990s, exemplified in part by a heightened focus on constructs such as community capacity, 8 social capital, 9 and developmental assets. 10,11 Currently, the incorporation of an assessment of community assets -in addition to health needs -has become a standard best practice promoted by organizations such as the National Association of County and City Health Officials (NACCHO) and the Public Health Accreditation Board in the United States. 3 Despite the movement toward the identification of community assets in the health needs assessment process, the application of an asset assessment approach guided by theory has received little attention in the health promotion literature to date. As health behavior is at the core of disease prevention and health promotion, comprising various types of behaviors that include health promoting behaviors (e.g., physical activity and fruit and vegetable consumption), risk behaviors (e.g., substance use), self-management behaviors (e.g., asthma management), and other preventive and compliance behaviors (e.g., screening, medical visits, and medication adherence), 1 we posit that asset assessment can be further enhanced for health promotion planning by explicitly identifying assets rooted in environments and settings that hold potential to influence the ultimate targets of health behavior and health outcomes. With the overarching aim of contributing to the science and practice of health promotion asset assessment, the purpose of this paper is threefold: (1) to describe the rationale for balancing a needs assessment with an assessment of the assets of a priority population, their environments, and the settings that surround them; (2) to explore a basic environmental asset assessment framework guided by ecological theories of health behavior and principles from the field of implementation science; and (3) to illustrate the application of an environmental asset approach within health promotion planning using examples from the scientific literature and the health promotion practice field.
Balancing the needs assessment with an assessment of assets: Why health asset assessment matters for health promotion Several reasons exist for incorporating an assessment of assets and capacities of the priority population and their environments, including the importance of a community empowerment vs. needs-based approach, the opportunity to enhance intervention effectiveness, and the potential to increase implementation and sustainability of health promotion interventions. In the following section we explore why the incorporation of an asset assessment approach in the health needs assessment process is essential and merits heightened emphasis in CHA and intervention planning.

Asset assessment for community empowerment
In following the credo in the medical field of "first, do no harm", in the field of health promotion practice, we must also take caution against victimizing a priority population or community by focusing solely on the multiple problems and deficits that confront them. McKnight and Kretzman 7 caution against the potentially adverse consequences of needs-based solutions to community development in which low-income neighborhoods may become environments of services where "…residents come to believe that their well-being depends upon being a client. " Given that all populations and communities have strengths and assets, health promotion program planners are in a unique position to co-learn and plan with communities to harness and activate these capacities and assets for health promotion planning and intervention.

Asset assessment for enhancing intervention effectiveness
Beyond the philosophical shift of an asset assessment approach, identifying the assets and capacities in a given community holds potential to broaden our understanding of potential factors that influence and promote positive health outcomes. An asset-based approach to program planning builds from the strengths of individuals, communities and their environments and is supported by theoretical-based concepts of positive deviance 12 and resiliency, 13 which focus on uncovering the factors associated with "positive" health and development, and not just the factors associated with the problem. Positive social interpersonal relationships and social cohesion 14,15 are examples of positive assets that hold potential for reducing exposure to youth risk behavior.

Asset assessment for implementation and sustainability
An important focus of the growing field of implementation research is on understanding the context in which health interventions are delivered, 16 which includes understanding how an intervention "couples" with the intended setting in order to increase the likelihood that programs will be effectively implemented and "stick" with the setting over time. 17,18 Balancing the needs assessment with an assessment of a community's assets -with specific attention to uncovering factors that can support and deliver an intervention within a given context or setting -holds potential to enhance a health program's implementation and sustainability by allowing for the identification of potential opportunities to couple or weave intervention efforts into existing settings -including organizations and communities.
Exploring a basic environmental asset assessment framework for health promotion planning Several definitions and conceptualizations have been cited in the literature to describe the general concept of a community asset, which is often used synonymously with the term resource. In the field of community organizing, Kretzman and colleagues 19 propose five key types of community assets: local residents' skills, passions, capacities, and willingness to contribute to a given project; local voluntary organizations, clubs and networks; local institutions such as schools and businesses; physical assets such as land and infrastructure; and economic assets. In the context of healthy adolescent development, the Search Institute defines assets as "…important relationships, skills, opportunities and values that help guide adolescents away from risk behaviors, foster resilience, and promote thriving", with a framework that includes both internal assets and external assets. 10 In the field of CHNA, The Community Tool Box 20 provides a robust definition of a community asset as "…anything that can be used to improve the quality of community life", which may range from individuals, to physical structures, to community services such as public transportation.

Applying ecological theory to asset assessment for health promotion planning
While the definitions of assets listed above share similarities, their differences underscore how asset assessment is often bound and shaped by the field for which it is being applied. In identifying assets for the specific purpose of health promotion planning and health behavior change, ecological models of health behavior provide a robust framework. [21][22][23] Ecological models of behavior stem from the premise that individuals are a 'product of their environment, ' and that environments hold the potential to directly and indirectly shape individuals' health and health behavior, 22 with pathways of influence that include social norms, social comparison and role models, social support, and other forms of social influence; opportunities or barriers to engage in a given behavior; information transfer; and incentive motivation via rewards or punishment. [21][22][23][24][25][26][27] Central to ecological models of health behavior are the principles of: multiple levels of influence (e.g., societal, organizational, interpersonal and individual) and multiple environments (e.g., policy, information, social, physical) that shape behavior; behavioral settings -such as schools, workplaces, and church -which can serve to both reach populations and influence behavior; and interactions of influence, which refers to the interaction between and among levels or environments that may enhance or inhibit a given health outcome. 22,27 These principles direct our attention to identifying the facets of environments and settings that can be harnessed for influencing health and health behavior. In defining the concept of environment, we adhere to Albert Einstein's broad conceptualization of environment as 'everything that isn't me' . 28 In following such a broad definition, we open up the environmental space for further conceptualization and identification of assets "outside the individual" that may be harnessed toward health promotion. Although there is great potential to further conceptualize environment, we build from existing social-ecological theory 22,27 and propose an initial framework for asset assessment guided by four key environments: policy environment, information environment, social/organizational environment, and the physical environment. The Policy Environment: While it is common to separate "policy" from "environment" (e.g., "policy and environmental interventions"), we share Sallis et al's 27 conceptualization of policy as a representation of a specific kind of environment. By stating "policy environment", we anchor policy to an environmental space, which may include a household setting (e.g., a family rule on TV watching), a classroom (e.g., classroom policy for earning more recess time for good behavior), a school (e.g., policy on only serving water at school events), a school district (e.g., daily PE class), or a state or nation (e.g., 30 minutes of physical activity a day for school children). Assessing existing policies and practices within different settings at the asset assessment phase allows for uncovering gaps in policy and practice, identifying policies that may adversely affect health, identifying existing policies that may not be fully implemented yet may provide an anchor for proposed health program efforts, and identifying existing policies in which a health focus can be interwoven, building off the "health in all policies" approach. 29 The Information Environment: The information environment broadly refers to the messaging within a given setting that holds potential to positively or negatively influence health or health behavior. This messaging can take many forms (e.g., verbal, nonverbal, written, symbolic) and be delivered via diverse communication channels (e.g., posters, newsletter, art, social media, marketing). Numerous examples of how the information environment can influence health and behavior are provided in the literature, ranging from national campaigns such as the VERB campaign and its influence on physical activity in middle school students, 30 to mass media campaigns for child survival, 31 to the role of menu labeling and promotion of healthier eating, 32 among others. As we discuss below, an important aspect of asset assessment is the exploration and identification of existing channels of communication (e.g., office newsletter, school marquee, church bulletin board) that can be incorporated into health intervention design. The Social, Cultural & Organizational Environment: This environment broadly refers to the types of social and cultural organization that exist within a given setting (e.g., neighborhood organizations, parent-teacher associations, cultural centers, etc.) as well as the specific types of social, cultural or organizational factors that relate to health and health behavior (e.g., family meals and their effect on childhood obesity 33 ; social support and physical activity in adolescents 34 ). In our asset assessment phase with the CATCH Middle School Program, 35 for example, we learned of existing social organizational activities, such as the literacy night in one school district, which then became the platform for incorporating a CATCH family health night. Asset assessment should include identifying the social organizations that exist within a given setting or community along with specific social, cultural and organizational factors and activities that can be incorporated into health promotion program planning. The Physical Environment: Moos,36 in his work on social ecology, defines the physical environment as encompassing both features of the built environment (e.g., how we construct our buildings or neighborhoods) and features of the natural environment (e.g., green space). In recent years, we have seen an explosion of research on facets of the built environment in topic areas that range from physical activity, 37 to the food environment, 38 to mental health, 39 among others. Beyond actual 'space' , the built environment may also encompass aspects such as children's access to physical activity equipment 40 and access to outlets that sell fruits and vegetables. 41,42 The natural environment includes access to green space-with emerging evidence that includes the positive effects of outdoors on physical activity and reduction of stress and depression. 43,44 An assessment of the physical environment holds potential to expand intervention opportunities for a given health problem.

Toward a conceptualization of environmental assets for health promotion
With guidance from ecological models of health behavior [21][22][23] and the premise that individuals and their behavior are shaped by their environment, we propose a refined conceptualization of community asset rooted in the construct of environmental asset. The focus on environment aims to direct health planners to an intentional assessment of assets rooted in the multiple environments (e.g., policy, social, information and physical) and settings (e.g., home, school, workplace, and neighborhood) that hold potential to shape health and health behavior. In building from previous definitions of a community asset, 20 we define an environmental asset as any aspect of the multiple environments that surround individuals that can be harnessed toward promoting the health of individuals and populations.
In Figure 1, we present a basic framework for conducting an environmental asset assessment for a health promotion and health behavior change intervention, guided by ecological models of health behavior. This framework begins with first identifying the settings where priority populations can be reached, which may include neighborhoods, schools, afterschool programs, and worksites, among other settings. The second step involves exploring the specific environmental assets within those settings that are posited to influence behavior, including the policy environment, the information environment, the social/cultural/organizational environment, and the physical environment. We offer this framework not as a recipe for environmental asset as-sessment, but rather as a practical and theoretical framework to complement existing health needs assessment approaches and for program planners and researchers to build from, modify, and enhance. As a brief example, we share findings in Figure 1 from a recent asset assessment workshop with afterschool program leaders (n = 24) conducted as part of the Central Texas Afterschool Network BOOST Initiative, an initiative funded by the St. David's Foundation aimed at enhancing child health in out-ofschool-time programs. 45 Applying environmental assets to health promotion In applying an environmental asset assessment approach to the field of health promotion, we take heart in the saying 'old wine in new bottles' , as the general environmental asset assessment framework we propose represents a common practice health promotion practitioners and researchers have long embraced. An early and brilliant example in the field of public health of using environmental assets is the fortification of salt with iodine, in which a natural environmental asset (salt) was harnessed for delivering a health intervention (iodine) to large masses of people, and thus reducing iodine-deficiency-related disease. 46 In the section below, we illustrate how health promotion practitioners and researchers have incorporated existing environmental assets into the design of health promotion programs and interventions. In doing so, we aim to highlight how the basic environmental asset framework described above can provide a new bottle of wine lens through which program planners can enhance asset assessment with greater intentionality for health promotion intervention design.

Policy environment
• School schedules as an environmental asset for physical activity: In our formative work with the CATCH Middle School Project, 35 we learned that middle school students were being dropped off at school in the morning and being directed to sit and wait in the cafeteria. Recognizing this opportunity to incorporate more physical activity opportunities, we partnered with school staff and principals to create an "Open Gym" policy/school practice in which schools opened their gyms and/or playfields for a free-play activity time with teacher supervision. • Campus Improvement Plans as a vehicle for child health policy: The nonprofit organization Texas Action for Healthy Kids worked with central Texas middle schools to take advantage of the Campus Improvement Plan, a document that describes the goals, practices and activities of a given campus for enhancing the student educational experience, to interweave child health policy. Campus Improvement Plans of schools participating in the initiative resulted in increased written policy language related to coordinated school health, such as scheduling of structured activity time. 35

Information environment
• Electric bills and physical activity in Brazil. In Sao Paulo, Brazil, the Agita Sao Paulo Program delivered physical activity messaging via an existing communication channel with widespread reach: residents' electric bills. 47 According to the authors, this approach required no funding from the program and reached 7 million residents. • Soap operas and HIV prevention. Soap operas and other entertainment media represent a powerful communication channel for interweaving health messaging, with a growing body of evidence on their effectiveness in promoting health-related knowledge, attitudes, intentions and behavior. 48 In an episode of the soap opera The Bold and the Beautiful, the insertion of an HIV/AIDS subplot along with displaying a national AIDS and STD hotline resulted in dramatic increases in hotline calls. 49

• 2-1-1 Information System and Community Health
Promotion. In the United States, the 2-1-1 system is a 3-digit phone number designated by the Federal Communications Commission as a free information resource to connect callers with health and social services in their community. 50 An emerging body of research provides evidence on the application of this community information resource as a promising communication channel for increasing health screening and delivery of health interventions. 50 tematic review of the literature shows that beauty salons and barbershops are both feasible and effective settings for health promotion, with topics that include cancer screening, hypertension, and diabetes. 58 Salons and barbershops are an example of a physical setting with wide reach of specific subgroups.

Discussion
Beyond the multiple benefits of conducting a CHNA for planning interventions aimed at advancing a population's health, conducting a CHNA has received heightened attention in recent years in countries such as the United States, where current health policy under the Patient Protection and Affordable Care Act now requires federally funded hospitals to conduct a CHNA every three years. 59 In this paper, we provide a basic conceptual framework for enhancing the health needs assessment process for health promotion planning via an assessment of environmental assets (e.g., policy, information, social, and physical environment) of a given community, organization or setting. A strength of this paper is the application of ecological theory of health behavior and principles of implementation science for identifying environmental assets that hold potential to enhance the design, implementation and sustainability of interventions directed at health behavior change.
In providing the basic conceptual framework for environmental asset assessment described in this paper, we recognize that there are other promising frameworks that hold value in guiding asset assessment for different fields and different purposes. For example, Green andHaines 60 conceptualize asset assessment for community development in terms of seven types of capital: human, social, physical, financial, environmental, political and cultural capital. As we describe in this paper, we posit that asset assessment can be enhanced via the lens of the field for which it is being applied. The basic environmental asset framework proposed in this paper for the field of health promotion planning differs from others by specifically applying both a behavioral-ecological perspective-one that seeks to identify environmental assets that can shape behavior, and an implementation science perspective-one that seeks to 'couple' and 'interweave' health promotion intervention strategies into existing environmental assets. This approach aims to increase health promotion intervention effectiveness while increasing implementation and sustainability of health promotion intervention initiatives.
Although we describe in this paper various examples of how environmental assets have been applied in health promotion research and practice, we recognize that the conceptual framework proposed here is basic, theory-based, and merits further empirical evaluation. This limitation notwithstanding, we hope that this paper serves as a catalyst to continue to grow the science and practice around environmental asset assessment for health promotion planning.

Conclusion and future directions
While many health promotion practitioners and researchers implicitly identify and apply environmental assets in the design and implementation of health promotion interventions, this paper provides a foundation for greater intentionality in assessing environmental assets that hold potential to directly shape health and health behavior. As described herein, the concept of environmental asset assessment holds great potential for furthering the field of health needs assessment. Future directions of this work include the development of a common vocabulary and constructs, further conceptualization of additional 'environments' important for health promotion-such as the arts and aesthetic environment (see Semenza and Krishnasamy 61 for inspiring examples), identification of methods, and attention to process for conducting an environmental asset assessment.
