Intentions, in turn, are predicted by attitudes and subjective norms. That is, the more positively a person regards a certain behavior or action and the more they perceive the behavior as being important to their friends, family, or society, the more likely they are to form intentions to engage in the behavior. Azjen, however, noted the importance of a behavior being This is a preview of subscription content, log in to check access. Ajzen, I. From intentions to action: A theory of planned behavior.

Ajzen and Fishbein's Theory of Reasoned Action (TRA) (1980)
Reasoned action theory is one of the most widely used theories in health behavior research and health intervention design, yet is not without its critics. TRA looks at behavioral intentions rather than attitudes as the main predictors of behavior. The attitude must be specific, since this specificity will allow the prediction in the resulting behavior. In fact, perceived behavioral control was added to the model to extend its applicability beyond purely volitional behaviors.

Fishbein and Ajzen's Theory of Reasoned Action TRA , updated by Ajzen and Fishbein in , is advanced in this paper as an appropriate theory for measuring student's intentions to adopt deep or surface processing and to adopt specific learning strategies. TRA is a decision theory that explains motivation by emphasising the specific processes that individuals use to make choices. TRA captures an individual's motivation by using the concept of intention to perform a behaviour. The survey items showed loadings on the constructs of deep, surface and strategic processing under this framework, indicating strong construct validity for the three learning factors. The TRA model was found to strongly positively influence the adoption of the deep processing construct, and to strongly negatively influence the adoption of the surface processing construct.
The theory of reasoned action TRA or ToRA aims to explain the relationship between attitudes and behaviors within human action. It is mainly used to predict how individuals will behave based on their pre-existing attitudes and behavioral intentions. An individual's decision to engage in a particular behavior is based on the outcomes the individual expects will come as a result of performing the behavior. Developed by Martin Fishbein and Icek Ajzen in , the theory derived from previous research in social psychology , persuasion models, and attitude theories. Fishbein's theories suggested a relationship between attitude and behaviors the A-B relationship.

Blair H. Sheppard, Jon Hartwick, Paul R. Two meta-analyses were conducted to Investigate the effectiveness of the Fishbein and Ajzen model in research to date. Strong overall evidence for the predictive utility of the model was found.
The strength of these associations, however, was influenced by the consideration of past behavior. Implications of these results for HIV prevention efforts are discussed. Because condom use can prevent infection with HIV and other STDs, health agencies have designed various interdisciplinary efforts, oriented by behavioral prediction models, to persuade people to use condoms consistently. For example, the health belief model Becker, ; Rosenstock, posits in part that increasing perceptions of vulnerability to HIV infection should increase precautionary behavior. The limited support for the perceived-risk hypothesis suggests a need for other behavioral models of HIV-risk-related behavior.
The Theory of Planned Behavior TPB started as the Theory of Reasoned Action in to predict an individual's intention to engage in a behavior at a specific time and place. The theory was intended to explain all behaviors over which people have the ability to exert self-control. The key component to this model is behavioral intent; behavioral intentions are influenced by the attitude about the likelihood that the behavior will have the expected outcome and the subjective evaluation of the risks and benefits of that outcome. The TPB has been used successfully to predict and explain a wide range of health behaviors and intentions including smoking, drinking, health services utilization, breastfeeding, and substance use, among others. The TPB states that behavioral achievement depends on both motivation intention and ability behavioral control.
The Epidemiologic Triad is a traditional model of infectious diseases causation, as described previously it consists of an agent, host and environment. The Theory of Reasoned Action is used to explain and predict behavior based on attitudes, norms and intentions. The construct of TRA are: behavioral beliefs, evaluations of behavioral outcomes which leads to attitude, then normative beliefs, motivation to comply which leads to subjective norms. Both the attitude and subjective norm lead to intention to perform the behavior, which results in the behavior.

Since the inception of the theory of reasoned action in late s by Martin Fishbein and Icek Ajzen, the theories of reasoned action and planned behavior and, in its more recent incarnation, the reasoned action approach, have been among the most influential approaches to predicting and understanding intentional behavior. The theories have been widely applied across multiple behaviors, contexts, and populations. The theory of reasoned action was the earliest version of the theory. The central construct of the theory is intention, a motivational construct that is considered the most proximal determinant of behavior. Intention reflects the extent to which an individual is likely to plan to do, and invest effort in pursuing, a given behavior.
Зная, чем грозит агентству Цифровая крепость, не мог же он участвовать в заговоре по ее созданию. И все же Сьюзан понимала, что остановить Хейла могут только его представления о чести и честности. Она вспомнила об алгоритме Попрыгунчик.
Мои люди несколько дней пытаются его взломать. - Это зашифрованный вирус, болван; ваше счастье, что вам не удалось его вскрыть. - Но… - Сделка отменяется! - крикнул Стратмор. - Я не Северная Дакота.
Джабба вытер губы. - Ты на месте. - А-га. - Не хочешь составить мне компанию.
Стратмор продолжал: - Внезапно я увидел в Цифровой крепости шанс, который выпадает раз в жизни. Ведь если внести в код ряд изменений, Цифровая крепость будет работать на нас, а не против. Ничего более абсурдного Сьюзан слышать еще не доводилось.
Подходя к шифровалке, он успел заметить, что шторы кабинета шефа задернуты. Это означало, что тот находится на рабочем месте.
Я бы предпочел, чтобы вы ни к чему не прикасались, - попросил. Ничего не трогайте. Ничего не читайте. - Энсей Танкадо… родился в январе… - Пожалуйста, - вежливо сказал Беккер.

Панк пристально смотрел на. - Вы похожи на полицейского. - Слушай, парень, я американец из Мериленда. Если я и полицейский, то уж точно не здешний, как ты думаешь. Эти слова, похоже, озадачили панка.
