Planned Behavior Theory

The theory of planned behavior was proposed by Icek Ajzen (1988, 1991). It is the successor of the Theory of Reasoned Action (TRA) jointly proposed by Ajzen and Fishbein (1975, 1980), because Ajzen research found that human behavior is not 100% voluntary, but controlled. Therefore, he expanded TRA, added a new concept of "Perceived Behavior Control" to himself, and developed it into a new behavior theory research model-Theory of Planned Behavior, TPB). ^[1]

Five Elements of Planned Behavior Theory

1. Attitude refers to an individual's positive or negative feelings about the behavior, that is, the attitude formed after the individual's evaluation of this particular behavior is conceptualized, so the components of attitude are often viewed A function of individuals' significant beliefs about the outcome of this behavior.

2. Subjective Norm refers to the social pressure that individuals feel about whether to take a certain behavior, that is, those individuals or groups that have influence on the behavioral decisions of individuals when predicting the behavior of others (salient indliduals or The impact of groups) on whether an individual takes a particular behavior.

3. Perceived Behavioral Control refers to the obstacles that reflect an individual's past experience and expectations. When an individual believes that the more resources and opportunities he has in his possession and the less expected obstacles, the perceived behavioral control of behavior is Stronger. There are two ways to influence it. One is to have a motivational meaning to the behavior intention; the other is that it can also directly predict the behavior.

4, Behavior Intention (Behavior Intention) refers to the individual's determination of the subjective probability of taking a specific behavior, it reflects the individual's willingness to take a specific behavior.

5. Behavior refers to the behavior that an individual actually takes.

Ajzen believes that all factors that can affect behavior are indirectly affecting performance through behavioral intentions. The behavioral intention is affected by three related factors. One is from the "attitude" of the individual, that is, the "Attitude" for adopting a specific behavior; the other is from the outside. The "subjective norm" in the present is the "subjective norm" that influences an individual to take a certain behavior; the last is derived from "Perceived Behavioral Control".

Generally speaking, the more positive an individual's attitude toward a certain behavior is, the stronger the individual's behavioral intention; the more positive the subjective norms of an behavior, the stronger the same individual's behavioral intention; and when the attitude and The more positive the subjective norms and the stronger the control of perceived behavior, the stronger will be the individual's behavioral intentions. In contrast to the basic hypothesis of rational action theory, Ajzen advocates treating the individual's will control over behavior as a continuum, with one end being behavior completely under the control of the will and the other end being behavior completely under the control of the will. And most human behavior falls somewhere between these two extremes. Therefore, to predict behaviors that are not completely under the control of will, it is necessary to increase the variable of behavioral perception control. However, when the individual's control of behavior is closer to the strongest degree, or the control problem is not a factor considered by the individual, the predictive effect of planned behavior theory is similar to that of rational behavior theory.

Planned Behavior Theory

Planned behavior theory has the following main points:

(1) The behavior that is not completely controlled by the will of the individual is not only affected by the intention of the behavior, but also by the actual control conditions of the individual's ability, opportunity, and resources to perform the behavior. When the actual control conditions are sufficient, the behavior intention directly determines the behavior;

(2) Accurate perceived behavior control reflects the status of actual control conditions, so it can be used as an alternative measurement index of actual control conditions to directly predict the possibility of behavior (as shown by the dashed line in the figure below). The accuracy of prediction depends on perception. The true degree of behavior control;

(3) Behavioural attitude, subjective norms, and perceived behavioral control are the three main variables that determine behavioral intention. The more positive the attitude, the greater the support of important others, and the stronger the perceived behavioral control, the greater the behavioral intention, and vice versa;

(4) Individuals have a large number of behavioral beliefs, but only a small number of behavioral beliefs can be obtained in a specific time and environment. These available beliefs are also called highlighting beliefs. They are behavioral attitudes, subjective norms, and perceived behavioral control. Cognitive and emotional basis;

(5) Personal and social and cultural factors (such as personality, intelligence, experience, age, gender, cultural background, etc.) indirectly affect behavioral attitudes, subjective norms, and perceived behavioral control by affecting behavioral beliefs, and ultimately affect behavioral intentions and behaviors;

(6) Behavioural attitudes, subjective norms, and perceived behavioral control can be completely distinguished conceptually, but sometimes they may have a common basis of belief, so they are both independent and related.
