the information contained herein. The absence of signs and symptoms of disease Contact us at: indicates health. email@example.com Illness would be the presence of conspicuous signs and symptoms of disease. People who use this model of health to guide their use of healthcare services may not seek preventive health services , or they may wait until they are very ill to seek care. Clinical model is the conventional model of the discipline of medicine. Role performance model Health is indicated by the ability to perform social roles. Role performance includes work, family and social roles, with performance based on societal expectations. Illness would be the future to perform a person’s roles at the level of others in society. This model is basis for work and school physical examination and physician –excused absences. The sick role, in which people can be excused from performing their social roles while they are ill, is a vital component of the role performance model. Adaptive model The ability to adapt positively to social, mental, and physiological change is indicative of health. Illness occurs when the person fails to adapt or becomes inadaptive toward these changes. As the concept of adaptation has entered other aspects of culture , this model has become widely accepted. Agent-Host-Environmental model: by Leavell and Clark(1965) This model is useful for examining causes of disease in an individual. The agent, host and environment interact in ways that create risk factors, and understanding these is important for the promotion and maintenance of health. An agent is an environmental factor or stressor that must be present or absent for an illness to occur. A host is a living organism capable of being infected or affected by an agent. The host reaction is influenced by family history,
age, and health habits.High Level Wellness Model by Dunn(1961): This model recognizes health as an ongoing process toward a person’s highest potential of functioning. This process involves the person, family and the community. He describes high-level wellness as “the experience of a person alive with the glow of good health, alive to the tips of their fingers with energy to burn, tingling with vitality – at times like this the world is a glorious place”. The wellness- illness continuum (Travis and Ryan 1988) is a visual comparison of high-level wellness and traditional medicine’s view of wellness. High level wellness according to Ardell(1977) is a lifestyle focused approach which you design for the purpose of pursuing the highest level of health within your capability.Holistic Health Model by Edelman and Mandle, 2002 Holism represents the interaction of a person’s mind, body and spirit within the environment. Holism is based on the belief that people (or their parts) can not be fully understood if examined solely in pieces apart from their environment. Holism sees people as ever charging systems of energy. In this model, nurses consider clients the ultimate experts regarding their own health and respect client’s subjective experience as relevant in maintaining health or assisting in healing. In holistic model of health, clients are involved in their healing process, thereby assuming some responsibility for health maintenance.Nightingale’s Theory of Environment Florence Nightingale’s environmental theory focuses on preventive care for populations. She suggested that disease was more prevalent in poor environments and that health could be promoted by providing adequate ventilation, pure water, quiet, warmth, light and cleanliness. "Poor environmental conditions are bad for health and that good environmental conditions reduce disease." This is one way to measure a person’s level of
health. This model views health as a constantly changing state, with high level wellness and death being on opposite ends of a graduated scale, or continuum. This continuum illustrates the dynamic state of health, as a person adapts to changes in the internal and external environments to maintain a state of well-being..Milio’s Framework for Prevention Nancy Milio developed a framework for prevention that includes concepts of community – oriented, population- focused care. Milio stated that behavioural patterns of the populations-and individuals who make up populations – are a result of habitual selection from limited choices. She challenged the common notion that a main determinant for unhealthful behavioural choice is lack of knowledge. Milio’s framework described a sometimes neglected role of community health nursing to examine the determinants of a community’s health and attempt to influence those determinants through public policy.Levels of Prevention Model This model, advocated by Leavell and Clark in 1975, has influenced both public health practice and ambulatory care delivery worldwide. This model suggests that the natural history of any disease exists on a continuum, with health at one end and advanced disease at the other. The model delineates three levels of the application of preventive measures that can be used to promote health and arrest the disease process at different points along the continuum. The goal is to maintain a healthy state and to prevent disease or injury.It has been defined in terms of four levels: Primordial prevention Primary prevention Secondary prevention Tertiary preventionPrimordial prevention
Prevention of the emergence or development of risk factors in population or countries in which they have not yet appeared. Efforts are directed towards discouraging children from adopting harmful lifestyles.Primary prevention An action taken prior to the onset of disease, which removes the possibility that the disease will ever occur. It includes the concept of positive health, that encourages the achievement and maintenance of an “acceptable level of health that will enable every individual to lead a socially and economically productive life.Secondary prevention Action which halts the progress of a disease at its incipient stage and prevents complications. The domain of clinical medicine. An imperfect tool in the transmission of disease. More expensive and less effective than primary prevention.Tertiary prevention All measures available to reduce or limit impairment and disabilities, minimize suffering caused by existing departures from good health and to promote the patients adjustment to irremediable conditions.The Health Belief Model This model is based on the premise that for a behavioral change to succeed, individuals must have the incentive to change, feel threatened by their current behaviour, and feel that a change will be beneficial and be at acceptable cost. They must also feel competent to implement that change . The purpose of the model is to explain and predict preventive health behavior.Tannahill Model of Health Promotion Health Education: communication activity aimed at enhancing well-being and preventing ill-health through favorably influencing the knowledge,
beliefs, attitudes and behavior of the community Health Protection: refers to the policies and codes of practice aimed at preventing ill-health or positively enhancing well-being, for example, no smoking in public places. Health Protection is responsible for the development and implementation of legislation, policies and programs in the areas of Environmental Health Protection, Community Care Facilities, and Emergency Preparedness Prevention: refers to both the initial occurrence of disease and also to the progress and subsequently the final outcomeThe Social Model A social health model is aimed at incorporating the social and economic, as well as biophysical context of health status, It is based on knowledge of the experience, views and practices of people with disabilities. It locates the problem within society, rather than within the individual with a disability Rules are determined within a framework of choice and independent living with strong support from organized disability communities. The biases of the social model include: o limiting the causes of disability either exclusively or mainly to social and environmental policies and practices, or o advancing perceptions of disability that emphasize individual rights rather than advancing broader economic rights.Social-Ecological Model The ultimate goal is to stop violence before it begins. Prevention requires understanding the factors that influence violence. CDC uses a four-level social-ecological model to better understand violence and the effect of potential prevention strategies. This model takes into consideration the complex interplay between individual, relationship, community and societal factors. It allows us to address the factors that put people at risk for experiencing or perpetrating violence.
Mental Health Promotion Model purpose of mental health promotion for people with mental illness is to ensure that individuals with mental illness have power, choice, and control over their lives and mental health, and that their communities have the strength and capacity to support individual empowerment and recovery. The person with mental illness is the central focus: participating in her/his community, involved in decision-making about mental health services, and choosing which supports are most appropriate. There are four key resources which should be available to the person to support their mental health: o a) mental health services; o b) family and friends; o c) consumer groups and organizations; and o d) generic community services and groups.AIDS Risk Reduction Model It believes change is a process. Individuals must go through with different factors affecting movement. This model proposes that the further an intervention helps clients to progress on the stage continuum, the more likely they are to exhibit change. Individuals must pass through three stages;A) Labeling - one must label their actions as risky forcontracting HIV (i.e. problematic). Three elements arenecessary Knowledge about how HIV is transmitted and prevented, Perceiving themselves as susceptible for HIV and Believing HIV is undesirableB) Commitment – this decision-making stage may result inone of several outcomes Making a firm commitment to deal with the problem Remaining undecided, Waiting for the problem to solve itself, or Resigning to the problem: Weigh cost and benefits- giving up pleasure (high risk) for less pleasure (low risk)C) Enactment – This includes three stages:
Seeking information, Obtaining remedies, and Enacting solutions.Summary Nursing must expand its efforts to design and implement interventions which support promotion of health and prevention of disease/illness and disability. Preventing illness and staying well involve complex, multidimensional activities focused not only on the individual, but also on families, groups and populations. Approaches to prevention should be comprehensive, encompass primary, secondary and tertiary levels of prevention and involve consumers in their formulation. Prevention strategies are more likely to be adopted by citizens who participate in influencing and developing such strategies. Nurses have developed many health models to understand the client’s attitudes and values about health and illness so that effective health care can be provided. These nursing models allow nurses to understand and predict client’s health behaviour, including how they use health services and adhere to recommended therapy.Reference 1. Craven RF, Hirnle CJ.
