What Is Theory Of Planned Behavior Model?
However, most of the behaviors we planned — eating out, watching movies, reading, playing games, etc. — did not involve involuntary reactions, so intention is still the best overall predictor. According to this theory, when people have time to plan their behavior, their own intentions are the best predictor of this behavior.
A key component of the model is behavioral intention; behavioral intention is affected by the relationship between the possibility of the behavior having the expected result and the subjective evaluation of the risk and benefit of the result.

| Theory Of Planned Behavior |
Planned behavior theory interprets individual behavior as the result of intention, and intention is affected by attitude, subjective norms and perceived behavior control. Planned behavior theory uses a person’s attitude and personal views, combined with perceived behavior control and subjective social norms, to influence their behavioral intentions, leading to behavior or actions.
Just like the current theories, favorable attitudes and supporting subjective norms provide motivation to participate in behavior, but only when the perceptual control of behavior is strong enough, will the specific intention to do so be formed.
Both theories assume that a person's behavioral intentions and attitudes toward certain behaviors depend on the ability to understand people's behavior and normative beliefs, as well as the social norms of the society in which they live.
A basic principle of planned behavior theory is that perceived behavioral control, norms, and attitudes are at the same level of abstraction in the predictive influence of intentions (that is, none of these three structures is considered to be the precedent of any of the others). In turn, it predicts behavior; Airan, 1991). The first structure of the theory is behavioral intention, that is, the motivational factors that affect behavior (Ajzen, 1991).
The stronger the intention to commit a particular behavior, the higher the likelihood of doing it. The second construct is the attitude towards behavior, that is, the degree to which a person positively or negatively evaluates a certain behavior.
Attitude Individual feelings of people and assessment of behavior. Concept Definition Behavioral Intention The perceived likelihood that a person will perform such behavior.
Intention stems from attitudes toward behavior and what people want them to do. Intelligent action theory meant that if someone were to evaluate behavior with a positive attitude and think that other important people, such as friends, peers, and family, wanted them to perform the behavior, then there is a higher intention or motivation for doing that behavior. behavior.
Aizen refined intelligent action theory by adding a third influencer called Perceived Behavior Control, which improved the predictability of the model. Formulating the Theory of Intelligent Action, Aizen and Fishbein (1980); Fishbein and Aizen (1975) hypothesized that most of the behaviors of interest to sociologists and behaviorists are likely to be controlled by will, and that perceptions of control are correspondingly strong.
We also assume that intentions are determined by attitudes towards behavior and subjective norms. Generally speaking, the more favorable attitudes and subjective norms are and the stronger perceptual control, the stronger people's intentions to formulate relevant behaviors should be. Generally speaking, the stronger the intention to engage in a certain behavior, the more likely it will happen (Ajzen, 1991, p. 181).
In other words, people may not express a particular attitude, but it can still influence their decisions. By asking a series of open-ended questions, obstacles and related attitudes can be clarified. Increasing knowledge alone does little to change behavior.
Increased perceived behavioral control, approval of positive attitudes, and greater perceptions of social approval influence the formulation of intentions, which are general goals associated with the planned level of people's engagement in behavior. A review of existing data shows that the residual influence of past behavior softens when intention and behavior scores are compatible, and disappears when intentions are strong and well-formed, expectations are realistic, and specific plans have been developed to realize intention. ... The predictability of intent and behavior is far superior to TRA or other previous theories of predicting and understanding human behavior.
TPB supports the human behavior hypothesis of TRA, which is defined by attitude and intention, and is characterized by the existence of social norms and the exercise of will control. The advantage of TPB is that it considers peer influences (subjective norms), which are related to initiating behaviors and sustaining behaviors (TAS and operational conditioning). The model assumes that behavior is planned; therefore, it predicts intentional behavior (Ajzen, 1991).
Planned Behavior Theory (TPB) is a cognitive theory of Azgen (1985), which suggests that a person's decision to engage in a particular behavior, such as gambling or to stop gambling, may be based on his or her intention to engage in that behavior (Fig. that intentions reflect the motivational factors that influence behavior; they are indicators of how much people are willing to try, how much effort they plan to put into performing the behavior.The TPB is more aware of how much it costs.Intention is likely to be completely different when intentionally planned and fulfilled behavior.
It is also possible that external factors directly force or prevent the behavior, regardless of its intention, depending on the degree to which the behavior is effectively controlled by the individual and the degree to which the perceived behavior control is an accurate measure of actual behavior control.
Like the existing predictive theories (behavior attitude, subjective norms, perceived behavior control, actual control, and intention), according to the principle of compatibility, the proposed variables should target behavior. As a decision-making model, TPB predicts that the person will choose the option with the strongest behavior tendency, that is, the option associated with the strongest intention (see Ajzen and Fishbein, 1969 for empirical support). ...
TRA is aware of the reality that while its attitudes indicate specific behavior, its perceived social norms may contradict it, suggesting a completely different response or behavior.
This theory is based on understanding and predicting human behavior, which allows it to be used for a wide variety of purposes. Informed Action / Planned Behavior Theory provides useful information for predicting health-related behavior and for planning and implementing health promotion and disease prevention programs. Two closely related theories - the theory of intelligent action and the theory of planned behavior - suggest that a person's health behavior is determined by his or her intention to behave. Planned Behavior Theory (TPB) originated as a theory of intelligent action in the 1980s to predict a person's intention to behave at a specific time and place.
Using a representative sample from the United States (N = 957), the aim of the present study was to test two alternative structural models of the relationship between the extraversion-related activity aspect, the consciousness aspect of industriousness, and cognition. behavioral control, emotional attitudes, subjective norms, intentions), social cognitive theory (self-efficacy, expectation of results) and transtheoretical model (behavioral change processes) and participation in physical activity.

Aizen refined the theory of intelligent action by adding a third influencing factor called Perceived Control of Behavior, which improved the predictability of the model. Intelligent action theory meant that if someone were to evaluate behavior with a positive attitude and think that other important people, such as friends, peers, and family, wanted them to perform the behavior, then there is a higher intention or motivation for doing that behavior. behavior.
However, since empirical research tends to determine only the main influence, recent formulas (such as Ajzen, 1991, 2012) and most empirical applications of this model regard perceived behavior control as a direct determinant of intention, and a state equals attitude And subjectivity. specification.
Recently, some scientists have criticized the theory for ignoring the needs of a person before taking a certain action, needs that will affect behavior regardless of the expressed attitude. In other words, people may not express a particular attitude, but it can still influence their decisions. Intention stems from attitudes toward behavior and what people want them to do.
A key component of the model is behavioral intention; behavioral intention is affected by the relationship between the possibility of the behavior having the expected result and the subjective evaluation of the risk and benefit of the result. TPB has been successfully used to predict and explain a wide range of health-related behaviors and intentions, including smoking, drinking, health care use, breastfeeding, and substance use. TPB believes that behavioral success depends on motivation (intention) and skills (behavior control).
The theory claims that three fundamental components, namely attitude, subjective norms, and perceived behavioral control, together form a person's behavioral intentions. Intelligent Action Theory is a precursor to TPB and includes only subjective attitudes and norms as predictors of intention (see Ajzen, 2005 for a more detailed comparison). TPB has been used to study the relationship between beliefs, attitudes, behavioral intentions and behavior in various areas of human life.
The most common and frequently used theories of health-related behavior change are examined, which potentially relate to repeated drug use as a behavior [7, 8, 14]; These include Health Belief Model (HBM), Protective Motivation Theory (PMT), Trans-Theoretical Health Behavior Change Model (TTM / SoC), Reasoned Action Theory (TRA) and Planned Behavior (TPB). Moreover, numerous theories have been criticized on the basis of their (in) effectiveness and lack of predictive power, the development of fuzzy constructs, and the lack of guidelines on how exactly they can be used to measure behavior or intention in relation to behavior [13]. Informed Action / Planned Behavior Theory provides useful information for predicting health-related behavior and for planning and implementing health promotion and disease prevention programs.
Two closely related theories-intelligent behavior theory and planned behavior theory-show that a person's healthy behavior depends on his or her behavioral intentions. When an individual has incomplete control of behavior, a person's behavioral intention cannot be the only determinant of behavior. The immediate precursor of behavior in TPB is the intention to perform the relevant behavior; the stronger the intention, the more likely the behavior is to follow.
In general, the stronger the intention to engage in a behavior, the more likely it should be (Ajzen, 1991, p. 181). Intention is reflected in the person's desire and in how much effort the person plans to put into the behavior. Intentions are assumed to reflect motivational factors that influence behavior; they indicate how hard people are willing to try, how much effort they plan to put into doing this behavior. As the theory is currently formulated, a favorable attitude and a supportive subjective norm provide motivation to participate in a behavior, but a specific intention to do so is formed only when the perceived control over the behavior is strong enough.
Like the existing predictive theories (behavior attitude, subjective norms, perceived behavior control, actual control, and intention), according to the principle of compatibility, the proposed variables should target behavior. Just as informed action theory has been extended to create TPB by adding actual and perceived behavioral control, it can also include other predictors that are not yet included in the theory.
In addition, people's perception of personal control of physical activity can also directly predict behavior. Some meta-analysis reviews support the theory of planned behavior to explain and predict the various physical activities of various groups of people, including ethnic minorities, young people, pregnant women, cancer patients, adult diabetic patients, cancer survivors, and the elderly. ...These results confirm previous research [12, 24, 43], which shows that within the framework of planned behavior theory, perceived behavior control is the most powerful predictor of intention and behavior. In summary, the study provides evidence that attitudes and perceived behavioral control interact with intentions, and this interaction largely determines the elderly's decision to continue engaging in physical activities.
Finally, in a review of 56 studies, the variation of behavioral intention attributed to the TPB structure was 40.9%. In 85.5% of health-related studies, PBC was an important predictor of behavioral intention, followed by attitude (81.5%) And subjective norms. 74.4%) [46]. In a study by Sweitzer et al. [28] The behavioral structure associated with TPB guides the development of intervention strategies. In addition, TPB (and TRA) helps explain people's social behavior by taking social norms as an important explanatory factor.
It is related to control beliefs, which are beliefs about the existence of factors that can promote or prevent behavior. He doesn't care how to identify the behavior that caused the behavior change. The model assumes that behavior is planned; therefore, it predicts intentional behavior (Ajzen, 1991).
Planned Behavior Theory (TPB) is a cognitive theory by Azgen (1985), which suggests that a person's decision to engage in a particular behavior, such as gambling or to stop gambling, may be based on his or her intention to engage in that behavior (Fig. Planned Behavior Theory (TPB) originated as a theory of intelligent action in 1980 to predict a person's intention to behave at a specific time and place. Consistency is associated with the discovery that behavior is not completely voluntary and cannot always be controlled. Perceived Behavioral Control was added to the model, and with this addition the theory was renamed TPB. The purpose of the article is to outline the validity of Planned Behavior Theory (TPB) for understanding people's intentions to use drugs. long term health when changing behavior.
Consistent with the theoretical framework of planned behavior theory, we tested the ability of teachers to predict teachers’ attitudes, perceptions of social norms, and behaviors, supervision and control beliefs in the context of cancer education. Since we do not have a solid theoretical foundation for the relationship between the components of the constraint and planned behavior theory, we did not apply structural modeling, which may be a proposed methodological approach for future research aimed at testing what is proposed by current research Model.
