Health Belief Model (HBM)

Good Essays
This study will be guided by the Health Belief Model (HBM). The HBM emphasis on how to predict health behaviour through consideration of the individual’s perceptions and attitudes an individual may have towards disease and negative outcomes of certain actions. The main construct of the model are perceived susceptibility, perceived seriousness, perceived barriers and perceived benefits (Janz & Becker, 1984). Any of these perceptions individually or in combination can be used to explain an individual’s health behavior. Recently, other constructs have been added to the HBM, thus the model now include self-efficacy cues to action and motivating factors (I. M. Rosenstock, Strecher, & Becker, 1988). According to the model health behaviour can …show more content…
Similarly, if the people don’t consider themselves to be at risk of TB/ MDRTB, their uptake of the BCG vaccine will be low and for those on treatment adherence will be poor. Therefore increased susceptibility is associated with healthy behaviours while decreased susceptibility is associated with unhealthy behaviour. The other important perception is on the severity or the seriousness of the disease. The perceived seriousness of a disease not only depend on the medical information available about the condition but also the individual beliefs about the disease and the effects it would have on their social life. TB may be perceived as serous disease not because of it infectiousness but because of the discrimination one may go through after diagnosis. Health behaviour will also depend on perceived benefits and the barriers that one has to overcome to attain the said benefits. Individuals are likely to adopt certain preventive measure/treatment based on the opinions regarding the effectiveness of that particular treatment/preventive measure …show more content…
The HBM construct of motivating factors is also inspiring in the present. Some enabling/supporting factors must be present to enable the predisposed individuals to seek or adopt the prescribed health behavior. Enabling factors such as accessibility of health services, financial status of the individual, the attitude of the health care workers, waiting hours at the health facility and support from the family members may have positive or negative influence on the individual’s motivation to seek TB treatment.

Social support is particularly very important when dealing with a stigmatized disease condition like in the case of TB. The kind of support a TB patient get from the family members, health personnel and friends will impact either positively or negatively on the patient’ s ability to seek treatment early and adhere to the treatment for the prolonged period of time. In the present study, the author will seek to determine how these factors interact and whether the level of

    Although, in later times, Rosentock and colleagues (1988) included self-efficacy as a core factor to further develop the explanation of individual differences in changes among health behaviours, making the five core beliefs a foundation for the HBM. Aside the self-efficacy element, the other four personal beliefs within the model may shape health behaviours through the perception of susceptibility and severity to disease as well as perception of benefits and costs of action. These beliefs account for cognitive influences on health behaviours. Perception of susceptibility to diseases refers to the subjective appraisal of the risk of developing ill health (Rosenstock, 1974). The severity belief covers the personal evaluation of the intensity of a health problem and its costs (Glanz, Barbara & Rimer, 2008).…

    It is important for health care professionals to attend to a patient’s psychological needs as well as biological needs. Including subjective language in addition to the medical objective jargon during patient encounters will help reduce the strict biomedical stance on the illness. In addition to this, modified attitudes toward AIDS patients can lead to improved health services to them. This can be solved by including education during training for healthcare professionals on the health implications of the stigma and how they can address them in a professional setting. It may be beneficial to create scenarios during healthcare training that depict interaction with an HIV/AIDS patient.…

    Each specific heath behavior is determined by an individual’s perception regarding the severity of the problem as well as the likelihood that they will suffer ill effects from the behavior. Moreover, they balance the perceived benefits of making a change in their behavior while appraising the barriers or costs of action change. The value gained from the benefits of behavior change (reducing risk of health problem) must outweigh any potential costs of undergoing the behavior change. Finally, individuals’ readiness to change can be pushed forward by various cues to action and success in change of behavior is determined by one’s self-efficacy to change. Health Belief Model can be applied to preventative health behaviors such as diet and increased exercise, decreased substance abuse, among other behavioral changes.…

    Imagine the difference in patient outcomes with a timely administration of antibiotics and one where the antibiotics are delayed by nursing care; the adaptation ability of the patient is adversely affected. The delay in antibiotics by nursing affects the environment, which affects, health and ultimately the patient. Directly managing each patient in regards to their individual needs will address the basic needs component of the regulator coping subsystem. Minimizing oscillations in the physiologic needs will provide maximum adaptation potential (Cypress, 2011). The CNS may not provide the direct care, but with advanced education, the CNS is able to focus the staff nurses on the proper care of patients with specific disease…

    Improving the health of individuals with chronic diseases needs to transform the health system from treatment to prevention to keep people as healthy as possible [125]. To improve the healthcare services, the roles and tasks of each health profession need to be identified, care services based on evidence-based practice guidelines need to be implemented, and follow-ups with the patients need to be conducted [126-128]. Also, the care service should be offered based on the patient’s status; “more complex patients may need more intensive management for a period of time to optimize clinic care and self-management”…

Family presence also concerns the ethical considerations of beneficence and paternalism. Beneficence involves the desire to help others (ANA, n.d.).…

    Each model of health holds a different idea of what ‘health’ is and what it means to be ‘healthy’. Being healthy is viewed as important as it affects how people experience illness and how they treat those who are ill (Baum, 2008). Some models look at health through a medical lens, whereas others view it from a social perspective. This essay will look at two models of health and discuss how they view health, how it aims to improve overall health and the limitations of the model. The models that will be discussed are the biomedical model and the social model.…

    This requires, first and foremost, a person who can listen well and understand the patient’s medical, emotional, and spiritual perspectives. Allen and Spitzer posit, “In the initial crisis phase, it is useful to explore the key benefits that shape families’ illness and coping strategies” (Allen & Spitzer, 2016, p. 189). It is also critical that during these interactions the Social Worker be attentive to the ability of the patient to understand and be competent to make care decisions on his/her own behalf.
