A positivistic approach to behavior research, TRA attempts to predict and explain one's intention of performing a certain behavior.The theory requires that behavior be clearly defined in terms of the four following concepts: Action (e.g. to go, get), Target (e.g. a mammogram), Context (e.g. at the breast screening center), and Time (e.g. in the 12 months).

The reasoned action approach is the latest version of the theoretical ideas of Martin Fishbein and Icek Ajzen, following the earlier theory of reasoned action [2] and the theory of planned behavior. [3] Those theoretical ideas have resulted in over a thousand empirical studies in behavioral science journals.
Each behavioural change theory or model focuses on different factors in attempting to explain behaviour change. Of the many that exist, the most prevalent are learning theories, social cognitive theory, theories of reasoned action and planned behaviour, transtheoretical model of behavior change, the health action process approach, and the BJ Fogg model of behavior change.
The theory was elaborated by Icek Ajzen for the purpose of improving the predictive power of the theory of reasoned action (TRA). Ajzen's idea was to include perceived behavioral control in TPB. [1] Perceived behavior control was not a component of TRA.
The theory of reasoned action aims to predict behavior based on how pre-existing attitudes and subjective norms determine behavioral intentions. In ethics, the intention principle states that whether an action is morally permissible sometimes depends on the agent's intention for performing this action.

The theory of reasoned action was in turn grounded in various theories of attitude such as learning theories, expectancy-value theories, consistency theories, and attribution theory. According to the theory of reasoned action, if people evaluate the suggested behavior as positive (attitude), and if they think their significant others want them ...
