The Theory Of Planned Behavior (TPB)

This theory was first created by Ajzen and Fishbein in 1980. This theory provides a framework to study the attitudes that support behaviours and suggests that the most important determinate of an individual’s behaviour is their behavioural intent. This is the individual’s intention to preform a certain behaviour, which is formed from a combination of their attitude towards the behaviour and the subject norm. (The subject norm is the individual’s perception of what others expect them to do).

It has substantial success in predicting a variety of behaviors (Conner & Sparks, 1996). It details the causes of an individual's decision to behave in a particular manner. Theory of Planned Behavioral is rooted in the fact that behavior reflects expected value. It aims to explain rationally motivated, intentional health and non-health behaviors. Extremely specific behavioral intentions measures that closely match the intended behaviors are used in the Theory of Planned Behavior. Behavioral intention measures can assess planning. The Theory of Planned Behavioral provides an account of the elements of behavior when both motivation and opportunity to process information are high (Conner & Armitage, 1998). Self-efficacy plays a vital role in this

The key predisposing factor that influences homeless veteran’s poor choice of diet is their perceived lack of control. For this reason, the constructs of the Theory of Planned Behavior (TPB) can be used to help understand and determine the beliefs that stimulate this behavior. Previous studies have shown that homeless veterans’ exhibit constant worry over perceived lack of control in regards to diet choice (Rojas-Guyler et al., 2014), and perceived control is a major construct of the TPB. The TPB asserts that intention and perceptions of capability will govern the likelihood that individuals will execute a particular behavior (McDermott et al., 2015). Consequently, homeless veterans will display a strong intention to eat the recommended daily

Health behaviour theorists have long attested to the importance of social influences in health decision making. For example, the prominent Social Cognitive Theory builds in a construct of outcome expectancies, of which social outcome expectancies, or the value of the anticipated reaction of those in one’s environment, play a role. In essence, an individual is going to consider anticipated approving or disapproving responses, by his/her peers, to a particular health decision, and the perceived reaction will affect the decision that is made (Lusczynska and Schwarzer, 2007). The Theory of Planned Behaviour describes the social influence as subjective norms, which are individual’s beliefs that significant others think that they should

Medication adherence is the concept of complying with a prescribed medication without deviation. Working on an inpatient floor with chronically ill children who take multiple medications on a daily basis is very challenging. Access to resources, education on medications, motivation to comply with medication regimens, and the capability of patients and families to obtain the prescribed medications are all factors that can affect adherence. Justice and beneficence are two other factors that can play a role in medication adherence. The focus of this paper will be on medication adherence in chronic patient populations. The Theory of Planned Behavior will be used as the basis of the framework for this paper.

There is a biblical text that states, “when I want to do right I do wrong”. Ok, so where am I going with this discussion? No one perfect….. Yes, surprise not one person falls into the perfect category. So, now, that the playing field is leveled; let’s play, shall we.

To aid to the understanding of the psychological influences of alcohol use, I choose the Theory of Planned Behaviour Model. The Theory of Planned Behaviour was created by Ajzen and Fishbein in 1974. Ajzen (1985) first defined intention as an attempt to perform a certain behaviour rather than with regard to the actual performance. Although alcohol may be beneficial to your health, however this is only if it is consumed in very small amounts. Those who are aged 18-35 are categorised with higher prevalence of alcohol use.

When considering health psychology it is important to recognise the various models it is made up of. The basis of this essay will be to take a look at the health belief model and the theory of planned behaviour, considering their historical origins, the positives and negatives of applying these approaches and examples of when they have been used. After some analysis it may offer some insight into possible improvements that could be implemented from further research. Also included will be an overview of how the models compare to each other and critical evaluation of research from this field.

Based on the TRA model, both attitudes and norms have direct influence towards behavioral intention in which is the potential predictor tool. All the external factors are just influence behaviour indirectly, through their influence on attitude and subjective norm (Tsai, Chen, & Chien, 2012).

This theory is considered to be a continuity of the Theory of Reasoned Action (Fishbein & Ajzen, 1967). This theory assumes that our behaviours are deliberate because it has been planned before it happened. Also, these behavioural intentions is as result of a combination of our several beliefs such

A theory that says that the strength of a tendency to act in a certain way depends on the strength of an expectation that the act will be followed by a given outcome and on the attractiveness of that outcome to the individual.”

This model has 5 stages; Pre-contemplation, contemplation, preparation, action and maintenance however the individual may not move from stage 1-5. Implementation intentions make explicit the mechanisms that reduce the ‘gap’ between intentions and the attainment of a behavioural goal. The Health Belief model, The protection motivation Theory as well as the Theory of planned all describe how a set of beliefs influence a person’s health. Beliefs that people hold towards health such as attitude, control risk perception and confidence have major impacts on their behavior. If a person is characterized by the protective motivation theory for example that person will ask themselves how severe the illness is they are trying to prevent?

By focusing on attitudes and norms, TRA provides a framework for identifying and measuring the underlying reasons for a person's intent to behave a certain way (or not). It is called the Theory of Reasoned Action because of the emphasis on understanding these reasons — not because the beliefs and attitudes themselves are necessarily reasonable or correct.

This study investigates whether young adults prefer to minimise risk whilst maximising reward, which can be illustrated through the Theory of Planned Behaviour. The study involved 696 undergraduates who had to choose between two stimuli to gain points. This was done in two stages, with 152 trials altogether. After the trials, subjects had to participate in a questionnaire to analyse how risky they perceived themselves to be. High variability and low variability results were compared and it was shown to be of significance difference in stage two. Overall, the results suggested a person’s preference was to choose the option with the least risk to gain the maximum reward as past experience and beliefs impact on a person’s choice seen through the

There are many theories that have information about behaviour, most of them reflect a cognitive perspective, focusing mainly on the role of conscious thought and feeling. This essay is going to be based on the theories based on theorist Sigmund Freud and B.F Skinner and their perception if our behaviour is beyond our control.
