The theory has been positively criticised for being a predictor of most human behaviour. The theory does not explain the process that takes place between intention and actual behaviour. The Theory of Reasoned Action: A Meta-Analysis of Past Research with Recommendations for Modifications and Future Research. All the advice on this site is general in nature. The most important difference between the two is the idea of perceived behavior control the belief that someone is actually capable of doing a behavior in question, such as exercising or eating healthier. Masud et al. Subjective norm refers to the social pressure the individual may be experiencing to perform such behaviours by their family and friends. Most people who are important to me approve of my exercising for at least 20 minutes, three times per week for the next three months. They found that predictions under the theory of reasoned action tended to vary based on the social setting whether someone is eating alone or with others and cultural orientation whether someone lives in an individualistic or collectivist culture. Peer influences on addiction. The Theory of Planned Behaviour (TPB; Ajzen, Citation 1985), an extension of the Theory of Reasoned Action (TRA; Fishbein & Ajzen, Citation 1975), has been the dominant theoretical approach to guide research on health-related behaviour for the past three decades.The theory is well recognised amongst researchers and is also familiar to many students, practitioners and policy-makers.

The Health Belief Model (HBM), the Theory of Reasoned Action (TRA), the Theory of Planned Behaviour (TPB) and the Trans-Theoretical Model (TTM) are distinct models containing (in common with other psychological models of health behaviour change) a number of components. Perceived behavioural control within this theory is again dependent on internal factors (ones ability and determination towards the specific behaviour) and external factors (the resources and support available to that individual). The theory of reasoned action has been widely used in psychology. This added component can further impact our behaviour in two ways: Perceived behavioural control thus can not only feed intention for a specific behaviour and impact it directly.
