Public Health Education, Research, and Disability Studies: A View From Epidemiology Elena M. Andresen, Ph.D.

Public health and medical research are commonly joined in the minds of scholars in disability studies and in disability communities. As a public health scientist I often balk at being identified as part of medical research and training. But in general, there are good reasons for thinking that the medicine and public health research groups have much more in common with each other, and less in common with disability studies. My goals in this commentary are to provide some brief definitions of my discipline within public health, examples of issues and problems when linking disability studies and public health, and to provide some ideas of solutions to our differences. I am unable to offer quick and acceptable answers for even this highly selected list of issues. But without some initial dialogue and our mutual passionate interest of learning and working together, our barriers and differences will continue to be more prominent than solutions. Epidemiology is one of the core disciplines in public health. It is always a component of training programs even for students who do not specialize in epidemiology (Institute of Medicine, 1988; 2003). A brief definition of epidemiology is "the study of the distribution and determinants of health related states or events and the application of this study to the control of these problems" (Last, 1995). Further, these terms are defined so that "study includes surveillance, observation, hypothesis testing, analytic research, and experiments... application to control makes explicit the aim of epidemiology -- to promote protect, and restore health" (Last, 1995). While these simple definitions are not particularly inflammatory to concepts accepted in disability studies, public health also incorporates a core concept that the study of populations allows public health scientists to understand how to prevent disease, and disability. The problem with definitions of "prevention" will be taken up later. In contrast, I provide, here, a definition for disability epidemiology that I hope resonates more fully with disability studies, and acknowledges disability as a state that has a social construct. My definition is still linked to my own discipline, but it helps set the scene for some of the selected issues that I raise later. As I argue at the end of this commentary, public health and disability studies need to continue to seek out and understand each other's terminologies. At this time I propose the following definition: Disability epidemiology is the study of the distribution, determinants, correlates, and outcomes of disability and application of this study to maximizing the health, participation, and quality of life of people and populations with disability. This definition makes a distinction between health states and disability: in public health, generally, these are combined to denote something that is a "bad outcome" that should be prevented. However, this separation of health and disability is accomplished in the Healthy People 2010 (Department of Health and Humans Services, 2000) chapter on disability (Objectives Report: Disability and Secondary Conditions; CDC, 2001). Prominent in this document is the following basic assumption about disability: "Disability is a demographic descriptor rather than a health outcome. It should be used to monitor disparities in health outcomes and social participation. The Americans with Disabilities Act (ADA) provides an important rationale for universal collection of disability status [in data collection]." This concept has also made its way into research and training publications (e.g., Andresen & Brownson, 2000; Centers for Disease Control and Prevention, 1998; 2002; Lollar, 2002; Lollar & Crews, 2003). While this separation is not novel to disability studies, we in public health are lagging behind and are currently attempting to catch up. Selected Issues in Public Health Research The following three examples are selected from among many challenges of communication and collaboration between public health and disability studies. Prevention-
It does not mean preventing people or discarding or devaluing people with impairment. But it does mean prevention of incidence and severity of injury, impairments, diagnoses, and conditions that can be a part of the picture of disability in a social context. In public health, research has produced campaigns to raise the nutritional intake of folic acid for women who may become pregnant to reduce the mortality from, and severity and incidence of spina bifida and anencephaly. Public health education and mandatory seat belt laws are seen as important to prevent mortality, and to prevent or reduce the severity of spinal cord injury and traumatic brain injury. This means there will continue to be some conflict between disability and public health communities. When the terminology of prevention is used, it may continue to raise the specter of preventing people with disability. I also want to emphasize that when public health professionals recoil from the idea that they are talking about "preventing people," they are often insensitive to daily social and built barriers, and the discrimination, faced by people with disabilities. I thought that society had managed to overcome the concept of eugenics until a colleague provide me with a copy of the 2003 New York Times Magazine article by Harriet McBride Johnson with her picture and the question "Should I have been killed at birth?" (McBride Johnson, 2003). She eloquently described her debate with a Princeton professor who advocated the potential for euthanizing babies whose lives he deems to be cognitively impaired enough to not be "persons." This example provides the best "shock" in a course I teach on disability epidemiology and a reality check for those of us who are self-congratulatory about public health ethics, justice, and disability. Quantitative Population Based Methods-
Participatory Action Research-
Public Health Training and Academic Expectations I have described problems relating to communication and terminology between the disability and public health scholarly communities, differences in methodologies and perspectives, and a few solutions or ongoing differences that might be resolved by joint academic training and collaborative experiences. My intent here is to provide more explicitly some of the issues regarding training and the academic culture in which many public health researchers work. Training and credentialing in public health is largely based on criteria of the Association of Schools of Public Health (see http://www.asph.org/) and consensus groups regarding expectations of competencies (e.g., Institute of Medicine, 1988; 2003). Training includes key disciplines like epidemiology and biostatistics, and more recently includes competencies in aspects of practice and emerging issues, for example genomics and informatics. Public health usually includes either a masters of public health (M.P.H.) or doctoral degree (Ph.D or Dr. PH). While schools and programs in public health produce many practitioners in public health, one of the criticisms of the field continues to be that programs produce more academics and researchers (e.g., Institute of Medicine, 1988), whose links to practice and communities can be loose, when they exist at all. While this is changing, but in epidemiology, especially, programs are likely to evaluate the success of their program and their graduates based on their research career trajectories, not their service and practice activities. Epidemiologic methods continue to evolve like they do in any science, requiring more and more training in statistical methods, molecular and genetic information, and familiarity and practice with computer applications and methods. Currently, public health training programs are encouraged to provide opportunities and competencies concerning communities, especially disadvantaged groups. In practice, this usually includes training and examples based on race and ethnic groups in the USA. In an evolving discipline, important content like disability awareness may be left behind or relegated to elective training. There are a number of efforts underway to incorporate disability in public health training (e.g., the disability and public health curriculum projects of the Centers for Disease Control and Prevention (CDC, 2004)). But the integration is not yet complete, and it will require the interest and participation of scholars in disability studies in order to achieve a greater level of maturity. Joint training is the ultimate solution. Considering the expectations of different disciplines, this suggests a fairly prolonged initial academic training (e.g., adding an M.P.H. to a doctorate in disability studies), or substantial retooling of more senior scholars by sabbatical or fellowship experiences. The problem of how to collaborate and communicate among disciplines also arises in considering academic careers and expectations. Typically, success is measured in academic circles by a steady progression through academic levels and by tenure. For most institutions, review of a candidate's success for promotion includes a combination of the elements of research (and scholarship), teaching, and service. Public health academic systems lean heavily on the expectations of traditional academic medicine. This means that success in research, by grants (especially a preference for RO1 projects funded by the National Institutes of Health) as well as publications, matters greatly in regards to promotion. In my setting, for example, promotion is reviewed and awarded scholarship depending on the number of articles a candidate has had included in peer-reviewed publications, candidate's publication in journals with high impact and prestige, and the number of citations to a candidate's first-authored work. Journal Citation Reports (Institute for Scientific Information, 2002) helps provide one important meter. An "impact factor" is figured from the average number of times that articles in the journal are cited. The count of citations to an article (or a first author) is also available via many electronic library resources (Thompson ISI Science Citation Index, 1995-2003). Personally, I need the help of a librarian to document most of this. But the list below gives just a hint of what an academic approaching tenure and promotion may face.
The Future I have raised questions and offered a few solutions concerning the future of collaboration and meaningful exchange between disability studies and public health. Two key suggestions may help the future progression of our alliance. First, I have argued for joint training. We need funding opportunities to support these goals. Second, there is an implicit need for transdisciplinary research teams to resolve and/or solve some of the problems and barriers to collaboration. Public health programs are being asked to incorporate transdisciplinary training (Institute of Medicine, 2003), but there is not a disability map in this general call for transdisciplinary competence. In order to move forward, we need to learn each other's methods and terminology, thus establishing a more equal partnership. We will be successful when we also generate new questions.
