Theory of planned behavior/ Theory of reasoned action

When was theory of reasoned action developed?

1967

Who developed theory of reasoned action?

Fishbein & Ajzek

What is the difference between TRA & TPB?

It has the added component of control It means that the outcome is affected by the amount people believe they can have control of the outcome.

What is outcome expectancy?

It is a variable-linking belief, attitude and expectation According to these models, people's evaluations of, or attitudes toward behavior are determined by their accessible beliefs about the behavior, where a belief is defined as the subjective probability that the behavior will produce a certain outcome. Specifically, the evaluation of each outcome contributes to the attitude in direct proportion to the person's subjective possibility that the behavior produces the outcome in question.

what is the main theory?

That are actions are due to cognitive thoughts and that we are rational. Once we have the right attitude, we can get the desired outcome.

Perceived behavioral control?

the conviction that one can successfully execute the behavior required to produce the outcome. The concept of self-efficacy is used as perceived behavioral control, which means the perception of the ease or difficulty of the particular behavior. It is linked to control beliefs, which refers to beliefs about the presence of factors that may facilitate or impede performance of the behavior.

What two elements does it use?

Attitudes and norms

what are the constructs of the theory of reasoned action?

Behavioral beliefs Evaluation of behavioral outcomes Normative beliefs Motivation to comply

Why is theory of reasoned action powerful?

Reasoned Action predicts behavioral intention, a compromise between stopping at attitude predictions and actually predicting behavior

What sets the theory of planned behavior and the theory of reasoned action apart from other theories?

While most models are conceptualized within individual cognitive space, the theory of planned behavior considers social influence such as social norm and normative belief, based on collectivist culture-related variables. Given that an individual's behavior (e.g., health-related decision-making such as diet, condom use, quitting smoking and drinking, etc.) might very well be located in and dependent on the social networks and organization (e.g., peer group, family, school and workplace), social influence has been a welcomed addition.

Behavioral intention?

an indication of an individual's readiness to perform a given behavior. It is assumed to be an immediate antecedent of behavior.[14] It is based on attitude toward the behavior, subjective norm, and perceived behavioral control, with each predictor weighted for its importance in relation to the behavior and population of interest.

Behavioral belief?

an individual's belief about consequences of particular behavior. The concept is based on the subjective probability that the behavior will produce a given outcome.

Subjective norm?

an individual's perception about the particular behavior, which is influenced by the judgment of significant others (e.g., parents, spouse, friends, teachers)

Normative belief?

an individual's perception of social normative pressures, or relevant others' beliefs that he or she should or should not perform such behavior.

Attitude toward behavior?

an individual's positive or negative evaluation of self-performance of the particular behavior. The concept is the degree to which performance of the behavior is positively or negatively valued. It is determined by the total set of accessible behavioral beliefs linking the behavior to various outcomes and other attributes.

What does the Theory of Planned Behavior specify?

the nature of relationships between beliefs and attitudes. According to these models, people's evaluations of, or attitudes toward behavior are determined by their accessible beliefs about the behavior, where a belief is defined as the subjective probability that the behavior will produce a certain outcome. Specifically, the evaluation of each outcome contributes to the attitude in direct proportion to the person's subjective possibility that the behavior produces the outcome in question.
