It is commonly used to “predict and explain a wide range of health behaviors and intentions” (Lamorte, 2016) and this is well demonstrated by Heidi Paruch’s study on weight issues in specific demographics. The TPB makes use of several factors which leads to an individual’s intentions that directly influences their behaviour or the probability of them to partake in a certain behaviour. It demonstrates how and why individuals react to different stimuli and scenarios in different manners. However, the TPB is limited by certain restrictions and assumptions listed by Dr Lamorte. He states that the theory is limited to a linear timeline, fails to include several factors such as environmental factors and does not allow for certain events such as past experiences, among several other things (Lamorte, …show more content…
By using these two theoretical examples it is possible to demonstrate how stress influences the probability of a patient to perform a health risk behaviour. The first health risk behaviour is the consumption of alcohol in an excessive manner by an indivdual that may lead to the development alcoholism and possibly chronic liver disease like alcoholic liver cirrosis. This individual has employment at a large firm but has a middle tier position and is yet to receive a promotion;he is depressed with his current standard of living. His current situation seems enough to justify the idea of his intended behaviour to cosume excessive alcohol to get rid of his depressed feeling. However, there are more likely behaviours for him to try first such as working harder to try attain that promotion. It is further discovered that this individual’s boss has a strong disliking of him and has little incentive to promote him. He starts to feel stress and experiences it in the form of frustration as his goal of being promoted is being restriced by his boss (Weiten, 2015). This psychosocial stress acts as a perceived external barrier that negatively affects their personal control beliefs (Lamorte, 2016) and this greatly increases the probability of him consuming alcohol to feel
