It was originally developed in the s and updated in the s. The model is based on the theory that a person's willingness to change their health behaviors is primarily due to their health perceptions. According to this model, your individual beliefs about health and health conditions play a role in determining your health-related behaviors. Key factors that affect your approach to health include:. Health experts often look for ways that such health belief models can impact the actions people take, including behaviors that can have an impact on both individual and public health.
The probability that a person will change their health behaviors to avoid a consequence depends on how serious they believe the consequences will be. For example:. The severity of an illness can have a major impact on health outcomes.
However, a number of studies have shown that perceived risk severity is actually the least powerful predictor of whether or not people will engage in preventive health behaviors. People will not change their health behaviors unless they believe that they are at risk. Research suggests that perceived susceptibility to illness is an important predictor of preventive health behaviors.
It's difficult to convince people to change a behavior if there isn't something in it for them. People don't want to give up something they enjoy if they don't also get something in return.
These perceived benefits are often linked to other factors, including the perceived effectiveness of a behavior. If you believe that getting regular exercise and eating a healthy diet can prevent heart disease, that belief increases the perceived benefits of those behaviors.
One of the major reasons people don't change their health behaviors is that they think doing so is going to be hard. Changing your health behaviors can cost effort, money, and time. Commonly perceived barriers include:. Sometimes it's not just a matter of physical difficulty, but social difficulty as well. For example, If everyone from your office goes out drinking on Fridays, it may be very difficult to cut down on your alcohol intake.
If you think that condoms are a sign of distrust in a relationship, you may be hesitant to bring them up. Perceived barriers to healthy behaviors have been shown to be the single most powerful predictor of whether people are willing to engage in healthy behaviors. When promoting health-related behaviors such as vaccinations or STD prevention, finding ways to help people overcome perceived barriers is important. Disease prevention programs can often do this by increasing accessibility, reducing costs, or promoting self-efficacy beliefs.
One of the best things about the Health Belief Model is how realistically it frames people's behaviors. It recognizes the fact that sometimes wanting to change a health behavior isn't enough to actually make someone do it.
Because of this, it includes two more elements that are necessary to get an individual to make the leap. These two elements are cues to action and self-efficacy. Finding ways to improve individual self-efficacy can have a positive impact on health-related behaviors. For example, one study found that women who had a greater sense of self-efficacy toward breastfeeding were more likely to nurse their infants longer.
The researchers concluded that teaching mothers to be more confident about breastfeeding would improve infant nutrition. Thinking that you will fail will almost make certain that you do. In fact, in recent years, self-efficacy has been found to be one of the most important factors in an individual's ability to successfully negotiate condom use. The Health Belief Model can be a helpful way for health educators to design interventions that can improve both individual and public health.
By understanding the factors that influence the health choices people make, programs can tackle ways to reduce barriers, improve knowledge, and help people feel more motivated to take action. It can also be a useful tool for thinking about your own approach to your health. Consider how things such as perceived susceptibility, perceived barriers, self-efficacy, and other elements of the model influence your choices, then look for things that you can do to make healthier choices in your life.The health belief model HBM is a social psychological health behavior change model developed to explain and predict health-related behaviors, particularly in regard to the uptake of health services.
Public Health Service   and remains one of the best known and most widely used theories in health behavior research.
One of the first theories of health behavior,  the HBM was developed in the s by social psychologists Irwin M. Rosenstock, Godfrey M. Hochbaum, S. Stephen Kegeles, and Howard Leventhal at the U.Lecture 2.4: Social Cognitive Models of Health Behavior
Public Health Service. The expectation is that a certain health action could prevent the condition for which people consider they might be at risk. The following constructs of the HBM are proposed to vary between individuals and predict engagement in health-related behaviors. Perceived susceptibility refers to subjective assessment of risk of developing a health problem. Individuals who perceive a high risk that they will be personally affected by a particular health problem are more likely to engage in behaviors to decrease their risk of developing the condition.
The combination of perceived severity and perceived susceptibility is referred to as perceived threat. Perceived severity refers to the subjective assessment of the severity of a health problem and its potential consequences.
Perceived seriousness encompasses beliefs about the disease itself e. Health-related behaviors are also influenced by the perceived benefits of taking action. Health-related behaviors are also a function of perceived barriers to taking action. In other words, the perceived benefits must outweigh the perceived barriers in order for behavior change to occur.
In a study about the breast and cervical cancer screening among Hispanic women, perceived barriers, like fear of cancer, embarrassment, fatalistic views of cancer and language, was proved to impede screening. Individual characteristics, including demographicpsychosocialand structural variables, can affect perceptions i. The HBM posits that a cue, or trigger, is necessary for prompting engagement in health-promoting behaviors.
Examples of cues to action include a reminder postcard from a dentist, the illness of a friend or family member, and product health warning labels.The Health Belief Model is a theoretical model that can be used to guide health promotion and disease prevention programs. It is used to explain and predict individual changes in health behaviors. It is one of the most widely used models for understanding health behaviors. Key elements of the Health Belief Model focus on individual beliefs about health conditions, which predict individual health-related behaviors.
The model defines the key factors that influence health behaviors as an individual's perceived threat to sickness or disease perceived susceptibilitybelief of consequence perceived severitypotential positive benefits of action perceived benefitsperceived barriers to action, exposure to factors that prompt action cues to actionand confidence in ability to succeed self-efficacy.
The Health Belief Model can be used to design short- and long-term interventions. The five key action-related components that determine the ability of the Health Belief Model to identify key decision-making points that influence health behaviors are:. These actions represent key elements of the Health Belief Model and can be used to design or adapt health promotion or disease prevention programs.Thesis about assessment in education
The Health Belief Model is appropriate to be used alone or in combination with other theories or models. To ensure success with this model, it is important to identify "cues to action" that are meaningful and appropriate for the target population.

This model adapts components of the Health Belief Model related to knowledge, skills, self-efficacy, and environmental support. Considerations for Implementation The Health Belief Model can be used to design short- and long-term interventions. The five key action-related components that determine the ability of the Health Belief Model to identify key decision-making points that influence health behaviors are: Gathering information by conducting a health needs assessments and other efforts to determine who is at risk and the population s that should be targeted.
Conveying the consequences of the health issues associated with risk behaviors in a clear and unambiguous fashion to understand perceived severity. Communicating to the target population the steps that are involved in taking the recommended action and highlighting the benefits to action. Providing assistance in identifying and reducing barriers to action.
Demonstrating actions through skill development activities and providing support that enhances self-efficacy and the likelihood of successful behavior changes.This means the model assumes that an individual takes an action based on their evaluation of the most likely outcome of engaging in a new or of changing existing behaviour.
The model is very popular and has proven its durability in the field of health education. It details the complex relationship between motivation, health behaviour and outcome.
During this period, tuberculosis was considered to be a serious health problem, but not everyone was going in for chest x-rays. Through his interviews with such people, Hochbaum developed a model that tried to predict the chances or likelihood of an individual taking up a recommended course of preventive action to safeguard his health.
The health belief model is a framework that helps indicate whether a person will adopt or not a recommended health behaviour. Therefore, by changing his perception, one can get him to adopt a new behaviour. There are fears that one is more prone to an illness compared to others. This could range from becoming bedridden, dying, to even social consequences in terms of the extend to which it affects a family, inability to work, etc.
Health belief model
The model, postulates that an individual get a treatment if he thinks that he is prone to a disease that has severe consequences. For the individual to make the decision, though, his evaluation of whether the benefits of taking up treatment will outweigh the difficulties that he will face in the process, is crucial.Articles of association amp alteration of articles
In addition to the six factors that influence the making of a health care decision, various demographic factors like age, sex, race, social class, education, employment status, knowledge and experience play a role in how a person perceives the urgency of taking proper action to deal with his health condition. A person, who feels that he is highly vulnerable to being afflicted by diseases, is more likely to pay attention to any health message. But barriers, like social pressure, may stop various changes even if the person is highly motivated.
The HBM suggests that a person's belief in a personal threat of an illness or disease together with a person's belief in the effectiveness of the recommended health behavior or action will predict the likelihood the person will adopt the behavior. The HBM derives from psychological and behavioral theory with the foundation that the two components of health-related behavior are 1 the desire to avoid illness, or conversely get well if already ill; and, 2 the belief that a specific health action will prevent, or cure, illness.
Ultimately, an individual's course of action often depends on the person's perceptions of the benefits and barriers related to health behavior.

There are six constructs of the HBM. The first four constructs were developed as the original tenets of the HBM. The last two were added as research about the HBM evolved. There are several limitations of the HBM which limit its utility in public health.
Limitations of the model include the following:.Ip assignment agreement sec review
The HBM is more descriptive than explanatory, and does not suggest a strategy for changing health-related actions. In preventive health behaviors, early studies showed that perceived susceptibility, benefits, and barriers were consistently associated with the desired health behavior; perceived severity was less often associated with the desired health behavior.
The individual constructs are useful, depending on the health outcome of interest, but for the most effective use of the model it should be integrated with other models that account for the environmental context and suggest strategies for change.Article petition tracker

Stephen Kegeles, and Howard Leventhal at the U. Public Health Service to better understand the widespread failure of screening programs for tuberculosis. Amendments to the model were made as late as to incorporate emerging evidence within the field of psychology about the role of self-efficacy in decision-making and behavior. The following constructs of the health belief model are proposed to vary between individuals and predict engagement in health-related behaviors e. The health belief model proposes that individuals who perceive a given health problem as serious are more likely to engage in behaviors to prevent the health problem from occurring or reduce its severity.
Perceived seriousness encompasses beliefs about the disease itself e. For instance, an individual may perceive that influenza is not medically serious, but if he or she perceives that there would be serious financial consequences as a result of being absent from work for several days, then he or she may perceive influenza to be a particularly serious condition.
Perceived susceptibility refers to subjective assessment of risk of developing a health problem. The health belief model predicts that individuals who perceive that they are susceptible to a particular health problem will engage in behaviors to reduce their risk of developing the health problem. Individuals with low perceived susceptibility may deny that they are at risk for contracting a particular illness.
Others may acknowledge the possibility that they could develop the illness, but believe it is unlikely. Individuals who believe they are at low risk of developing an illness are more likely to engage in unhealthy, or risky, behaviors. Individuals who perceive a high risk that they will be personally affected by a particular health problem are more likely to engage in behaviors to decrease their risk of developing the condition. The combination of perceived severity and perceived susceptibility is referred to as perceived threat.
Perceived severity and perceived susceptibility to a given health condition depend on knowledge about the condition.In this series of lessons, Blender artist Beorn Leonard explains all the fundamentals of character animation in Blender.
