The Theory of Reasoned Action (ToRA or TRA)
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 1967, 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).
However, critics estimated that attitude theories were not proving to be
good indicators of human behavior. The ToRA was later revised and
expanded by the two theorists in the following decades to overcome any
discrepancies in the A-B relationship with the Theory of Planned Behavior (TPB) and Reasoned Action Approach (RAA). The theory is also used in communication discourse as a theory of understanding.
The primary purpose of the TRA is to understand an individual's voluntary behavior by examining the underlying basic motivation to perform an action. ToRA states that a person's intention to perform a behavior is the main predictor of whether or not they actually perform that behavior. Additionally, the normative component (i.e. social norms surrounding the act) also contributes to whether or not the person will actually perform the behavior. According to the theory, intention to perform a certain behavior precedes the actual behavior. This intention is known as behavioral intention and comes as a result of a belief that performing the behavior will lead to a specific outcome. Behavioral intention is important to the theory because these intentions "are determined by attitudes to behaviors and subjective norms". The theory of reasoned action suggests that stronger intentions lead to increased effort to perform the behavior, which also increases the likelihood for the behavior to be performed.

Key Concepts and Conditions
Behavior
A positivistic approach
to behavior research, ToRA 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).
According to TRA, behavioral intention is the main motivator of
behavior, while the two key determinants on behavioral intention are
people's attitudes and norms.
By examining attitudes and subjective norms, researchers can gain an
understanding as to whether or not one will perform the intended action.
Attitudes
According to TRA, attitudes are one of the key determinants of behavioral intention and refer to the way people feel towards a particular behavior. These attitudes are influenced by two factors: the strength of behavioral beliefs regarding the outcomes of the performed behavior (i.e. whether or not the outcome is probable) and the evaluation of the potential outcomes (i.e. whether or not the outcome is positive). Attitudes regarding a certain behavior can either be positive, negative or neutral.
The theory stipulates that there exists a direct correlation between
attitudes and outcomes, such that if one believes that a certain
behavior will lead to a desirable or favorable outcome, then one
is more likely to have a positive attitude towards the behavior.
Alternatively, if one believes that a certain behavior will lead to an
undesirable or unfavorable outcome, then one is more likely to have a negative attitude towards the behavior.
Behavioral Belief
Behavioral belief allows us to understand people's motivations for their behavior in terms of the behavior's consequences.
This concept stipulates that people tend to associate the performance
of a certain behavior with a certain set of outcomes or features.
For example, a person believes that if he or she studies for a month
for his or her driver's license test, that one will pass the test after
failing it the first time without studying at all. Here, the behavioral
belief is that studying for a month is equated with success, whereas not
studying at all is associated with failure.
Evaluation
The evaluation of the outcome refers to the way people perceive and evaluate the potential outcomes of a performed behavior. Such evaluations are conceived in a binary "good-bad" fashion-like manner.
For example, a person may evaluate the outcome of quitting smoking
cigarettes as positive if the behavioral belief is improved breathing
and clean lungs. Conversely, a person may evaluate the outcome of
quitting smoking cigarettes as negative if the behavioral belief is
weight gain after smoking cessation.
Subjective Norms
Subjective norms are also one of the key determinants of behavioral intention and refer to the way perceptions of relevant groups or individuals such as family members, friends, and peers may affect one's performance of the behavior. Ajzen defines subjective norms as the "perceived social pressure to perform or not perform the behavior". According to TRA, people develop certain beliefs or normative beliefs as to whether or not certain behaviors are acceptable. These beliefs shape one's perception of the behavior and determine one's intention to perform or not perform the behavior.
For example, if one believes that recreational drug use (the behavior)
is acceptable within one's social group, one will more likely be willing
to engage in the activity. Alternatively, if one's friends groups
perceive that the behavior is bad, one will be less likely to engage in
recreational drug use. However, subjective norms also take into account
people's motivation to comply with their social circle's views and perceptions, which vary depending on the situation and the individual's motivations.
Normative Beliefs
Normative
beliefs touch on whether or not referent relevant groups approve of the
action. There exists a direct correlation between normative beliefs and
performance of the behavior. Usually, the more likely the referent
groups will approve of the action, the more likely the individual
perform the act. Conversely, the less likely the referent groups will
approve of the action, the less likely the individual will perform the
act.
Motivation to Comply
Motivation to comply addresses the fact that individuals may or may not comply with social norms of the referent groups surrounding the act. Depending on the individuals motivations in terms of adhering to social pressures, the individual will either succumb to the social pressures of performing the act if it is deemed acceptable, or alternatively will resist to the social pressures of performing the act if it is deemed unacceptable.
Behavioral Intention
Behavioral
intention is a function of both attitudes and subjective norms toward
that behavior (also known as the normative component). Attitudes being
how strongly one holds the attitude toward the act and subjective norms
being the social norms associated with the act. The stronger the
attitude and the more positive the subjective norm, the higher the A-B
relationship should be. However, the attitudes and subjective norms are
unlikely to be weighted equally in predicting behavior. Depending on the
individual and situation, these factors might have different impacts on
behavioral intention, thus a weight is associated with each of these
factors.
A few studies have shown that direct prior experience with a certain
activity results in an increased weight on the attitude component of the
behavior intention function.
Formula
In its simplest form, the TRA can be expressed as the following equation:
where:
- BI = behavioral intention
- (AB) = one's attitude toward performing the behavior
- W = empirically derived weights
- SN = one's subjective norm related to performing the behavior
Conditions
The
TORA theorists note that there are three conditions that can affect the
relationship between behavioral intention and behavior. The first
condition is that "the measure of intention must correspond with respect
to their levels of specificity".
This means that to predict a specific behavior, the behavioral
intention must be equally specific. The second condition is that there
must be "stability of intentions between time of measurement and
performance of behavior".
The intention must remain the same between the time that it is given
and the time that the behavior is performed. The third condition is "the
degree to which carrying out the intention is under the volitional
control of the individual".
The individual always has the control of whether or not to perform the
behavior. These conditions have to do with the transition from verbal
responses to actual behavior.
Scope and Limitations
Scope
While Fishbein and Ajzen
developed the ToRA within the field of health to understand health
behaviors, the theorists asserted that TRA could be applied in any given
context to understand and even predict any human behavior.
According to Sheppard et al., behavioral intention can predict the
performance of "any voluntary act, unless intent changes prior to the
performance or unless the intention measure does not correspond to the
behavioral criterion in terms of action, target, context, time-frame
and/or specificity".
Their statement asserts that according to TRA, the measure of
behavioral intention can predict whether or not an individual will
perform a certain act, as long as the behavioral intention remains the
same and the behavior is clearly and properly defined.
Broadening the scope of TRA, Sheppard conducted a study in which they
applied TRA in situations that did not completely comply or conform with
Fishbein and Ajzen's
framework. Surveying 87 previous empirical studies, they applied the
theory in contexts where the individual did not have full volitional control over the behavior and/or where individuals did not have all the information to develop the intention.
To their surprise, they found that the theory of reasoned action could
successfully be applied in situations that did not fully adhere to the
three formal terms and conditions specified by the theory.
Limitations
Although
the scope of TRA is wide, the theory still has its limitations and like
any other theory, needs constant refinement and revision particularly
when extending to choice and goals.
The distinction between a goal intention and a behavioral intention
concerns the capability to achieve one's intention, which involves
multiple variables thus creating great uncertainty. Ajzen
acknowledged that "some behaviors are more likely to present problems
of controls than others, but we can never be absolutely certain that we
will be in a position to carry out our intentions. Viewed in this light
it becomes clear that strictly speaking every intention is a goal whose
attainment is subject to some degree of uncertainty."
According to Eagly and Chaiken, TRA does not take into account
that certain conditions that enable the performance of a behavior are
not available to individuals.
Since the ToRA focuses on behaviors that people decisively enact, the
theory is limited in terms of being able to predict behaviors that
require access to certain opportunities, skills, conditions, and/or
resources. Additionally, certain intentions do not necessarily play a role in terms of connecting attitudes and behavior.
According to a study conducted by Bagozzi and Yi, the performance of a
behavior is not always preceded by a strong intent. In fact, attitudes
and behaviors may not always be linked by intentions, particularly when
the behavior does not require much cognitive effort.
Development and investigation
In 1979, H. C. Triandis
proposed expanding TORA to include more components. These factors were
habit, facilitating conditions, and affect. When a person performs a
behavior in a routine manner they form a habit. Facilitating conditions
are conditions that make completion of an action more or less difficult.
Both of these conditions affect their behavior directly. On the other
hand, affect is the emotional response a person has towards a behavior
and this emotional response only affects behavioral intention rather
than directly affecting behavior. This expanded version of TORA has been used to study behaviors like women's participation in mammography procedures.
In 1985, Ajzen extended TORA to what he refers as the theory of planned behavior
(TPB). This involves the addition of one major predictor—perceived
behavioral control. This addition was introduced to account for times
when people have the intention to conduct the behavior, but the actual
behavior is thwarted because of subjective and objective reasons.
In the theory of planned behavior, the attitude, subjective norms, and
behavioral control have "important although differently weighted effects
on a person's intention to behave".
In spite of the improvement, it is suggested that TORA and TPB
only provides an account of the determinants of behavior when both
motivation and opportunity to process information are high. Further
research demonstrating the casual relationships among the variables in
TPB and any expansions of it is clearly necessary. The model also mentions little about the memory process.
Applications of the theory
The
theory of reasoned action has been used in many studies as a framework
for examining specific kinds of behavior such as communication behavior,
consumer behavior and health behavior. Many researchers use the theory
to study behaviors that are associated with high risks and danger, as
well as deviant behavior. In contrast, some research has applied the
theory to more normative and rational types of action. Researchers
Davies, Foxall, and Pallister suggest that the theory of reasoned action
can be tested if "behavior is measured objectively without drawing a
connection to prior intention". Most studies, however, look at intention because of its central role in the theory.
Communication
College fraternity and sorority hazing
Theory of Reasoned Action has been applied to the study of whistle-blowing intentions and hazing in college organizations, specifically fraternities and sororities.
Hazing is understood to be "any activity expected of someone that joins
a group, which humiliates, degrades, abuses or endangers its victims".
In the United States, there have been a variety of hazing incidents
that have resulted in death and harm of students on several college
campuses. Whistle-blowing "involves an individual with some level of
unique or inside knowledge using public communication to bring attention
to some perceived wrongdoing or problem.
Whistle-blowing is significant to this issue because individuals who
are aware of hazing incidents can come forward to university officials
and make the occurrence of hazing known. In their study, Richardson et
al. set out to study whistle-blowing by using the theory of reasoned
action as a framework to predict whether or not individuals will come
forward about report hazing incidents. Their study served to examine
whether the relationships suggested by the TRA model remain true in
predicting whistle blowing intentions, and if these relationships would
change depending on the severity of the hazing incident.
Richardson et al. surveyed a sample of 259 students from Greek
organizations at university in the Southwestern United States. The
survey questions measured the different aspects of the TRA model:
behavioral beliefs, outcome evaluations, attitude toward the behavior,
normative beliefs, motivation to comply, subjective norms, and the
consequence endogenous variable. The questions asked respondents to rate
their responses on various 7 point scales. "Participants in the study
responded to one of three scenarios, varying in level of severity,
describing a hazing situation occurring in their fraternity or
sorority".
In line with the theory, the researchers wanted to identify if
attitudes held about hazing, dangerous activity, and group affiliation,
along with subjective norms about whistle-blowing (reactions by others,
consequences of reporting the action, isolation from the group) would
influence whether or not an individual would go through with reporting a
hazing incident. The results of the study found that individuals were
more likely to report, or whistle-blow, on hazing incidents that were
more severe or harmful to individuals. Simultaneously, individuals were
also concerned about the perceptions of others' attitudes towards them
and the consequences they may face if they reported hazing incidents.
Knowledge sharing in companies
TRA
is used to examine the communication behavior in corporations. One of
the behaviors TRA helped characterize is knowledge sharing (KS) in
companies. In the study conducted by Ho, Hsu, and Oh, they proposed two
models to construct KS process by introducing TRA and game theory (GT).
One model captures personal psychological feelings (attitudes and
subjective norms), the other model not only captures personal feelings
but also takes other people's decisions into consideration. By comparing
the two models, researchers found that the model based on TRA has a
higher predictive accuracy than the model based on TRA and GT. They
concluded that employees "have a high probability of not analyzing the
decisions of others",
and whether taking other colleague's decision into account has a great
impact on people's KS behavioral intention. It is indicated that "the
more indirect decision-makers there are in organizations, the less
effective is KS". To encourage KS, company managers should avoid including indirect decision-makers in the projects.
Consumer behavior
Coupon usage
Coupon
usage has also been studied through the theory of reasoned action
framework by researchers interested in consumer and marketer behavior.
In 1984, Terence Shimp and Alican Kavas applied this theory to coupon
usage behavior, with the research premise that "coupon usage is
rational, systematic, and thoughtful behavior" in contrast with other applications of the theory to more dangerous types of behavior.
Theory of Reasoned Action serves as a useful model because it can
help examine whether "consumers' intentions to use coupons are
determined by their attitudes and perceptions of whether important
others think one should or should not expend the effort to clip, save,
and use coupons".
The consumer's behavior intentions are influenced by their personal
beliefs about coupon usage, meaning whether or not they think saving
money is important and are willing to spend the time clipping coupons.
These potential beliefs also influenced the coupon user's thoughts about
what others think about their usage of coupons. Together, the coupon
user will use their own beliefs and the opinions of others to form an
overall attitude towards coupon usage. To approach this study, Shimp
and Alican surveyed 770 households and measured the aspects of the TRA
model in terms of the participant's responses. The received responses
indicated that consumers' norms are "partially determined by their
personal beliefs toward coupon usage, and to an even greater extend,
that attitudes are influenced by internalizing others' beliefs".
Positive attitudes towards this behavior are influenced by an
individual's perceptions that their partners will be satisfied by their
time spent and efforts made to save money.
Brand loyalty
TRA has been applied to redefine brand loyalty.
According to the theory of reasoned action, the antecedents of purchase
behaviour are attitudes towards the purchase and subjective norm. In
1998, Ha conducted a study to investigate the relationships among
several antecedents of unit brand loyalty (UBL) by introducing TRA.
Consumers are brand loyal when both attitude and behavior are favorable.
In his study, Ha developed a table indicating 8 combinations of
customers' brand loyalty based on their loyalty on 3 variables –
attitude towards the behavior, subjective norm, and purchase behavior is
loyal. According to Ha, marketing managers should not be discouraged by
a temporary disloyalty and need to strive for grabbing brand loyalty
when customers are showing loyalty to two of the three variables, but
they need to rediagnose their customers' brand loyalty when customers
are showing loyalty to only one of them. The main focus should be
pointed at either enhancing the consumer's attitude toward their brand
or adjusting their brand to the social norms.
Green Behaviors
TRA has also been used to study consumer attitudes towards renewable energy.
In 2000, Bang, et. al found that people who cared about environmental
issues like pollution were more willing to spend more for renewable
energy.
Similarly, a 2008 study of Swedish consumers by Hansla et. al showed
that those who with a positive view of renewable energy were more
willing to spend money on sustainable energy for their homes.
These studies are evidence that the emotional response people have
towards a topic affects their attitude, which in turn affects their
behavioral intent. These studies also provide examples for how the TRA
is used to market goods that might not make the most sense from a
strictly economic perspective.
In addition, Mishara et.al 's research proved there is a
positively relation between behavioral intention and actual behavior in
Green Information Technology (GIT) acceptance. Those professionals with
positive intentions towards GIT tend to exploit GIT into practice.
Health behavior
Condom use
Theory
of Reasoned Action has been frequently used as a framework and
predictive mechanism of applied research on sexual behavior, especially
in prevention of sexually transmitted disease such as HIV. In 2001, Albarracín, Johnson, Fishbein, and Muellerleile applied theory of reasoned action (TRA) and theory of planned behavior (TPB) into studying how well the theories predict condom use.
To be consistent with TRA, the authors synthesized 96 data sets (N =
22,594), and associate every component in condom use with certain
weight. Their study indicates that the theories of reasoned action and
planned behavior are highly successful predictors of condom use.
According to their discussion, "people are more likely to use condoms if
they have previously formed the corresponding intentions. These
intentions to use condoms appear to derive from attitudes, subjective
norms, and perceived behavioral control. These attitudes and norms, in
turn, appear to derive from outcome and normative beliefs. Nevertheless,
whether behavior was assessed retrospectively or prospectively was an
important moderator that influenced the magnitude of the associations
between theoretically important variables."
Sexual behavior in teenage girls
In
2011, W.M. Doswell, Braxter, Cha, and Kim examined sexual behavior in
African American teenage girls and applied the theory as a framework for
understanding this behavior. The theory of reasoned action can explain
these behaviors in that teens' behavioral intentions to engage in early
sexual behavior are influenced by their pre-existing attitudes and
subjective norms of their peers. Attitudes in this context are favorable
or unfavorable dispositions towards teenage sexual behavior.
Subjective norms are the perceived social pressure teenagers feel from
their friends, classmates, and other peer groups to engage in sexual
behavior. As a framework, the TRA suggests that adolescents will
participate in early behavior because of their own attitudes towards the
behavior and the subjective norms of their peers. In this case,
intention is the willful plan to perform early sexual behavior.
Findings from the student showed that the TRA was supportive in
predicting early sexual behavior among African American teenage girls.
Attitudes towards sex and subjective norms both correlated with
intentions to participate in early sexual behavior in the study's
sample.
Pediatricians, parents and HPV vaccinations
A 2011 study examining pediatricians' behaviors surrounding the Human Papillomavirus (HPV) vaccine
found that TRA predicted the pediatricians would encourage parents to
get their daughters vaccinated. Roberto, Krieger, Katz, Goei, and Jain
discovered that the norms surrounding this topic were more important in
predicting behavior than perceived behavioral control.
Exercise
The
public health community, interested in reducing rising obesity rates,
has used TRA to study people's exercise behavior. A 1981 study by
Bentler and Speckart revealed that intent to exercise was determined by a
person's attitude toward exercise, as predicted by TRA.
In a broader literature review on the study of exercise using TRA and
TPB, it was determined that behavioral intent to exercise is better
framed by TRA than TPB because perceived behavioral control did not have
a significant effect on the intent to exercise.
Critiques
Challenges
According to Fishbein's and Ajzen's original (1967) formulation
of TRA, a behavioral intention measure will predict the performance of
any voluntary act, unless intent changes prior to performance or unless
the intention measure does not correspond to the behavioral criterion in
terms of action, target, context, time-frame and/or specificity. The model of TRA has been challenged by studies determined to examine its limitation and inadequacy.
The major problem of TRA is pointed out to be the ignorance of
the connections between individuals, both the interpersonal and social
relations in which they act, and the broader social structures which
govern social practice. Although TRA recognizes the importance of social norms, strategies are limited to a consideration of individual perceptions
of these social phenomena. Individual's belief, attitudes and
understandings are constituted activity, therefore the distinction of
the two factors is ambiguous. In 1972, Shwartz and Tessler noted that
there are other major and subjective determinants of intentions at play
that go beyond attitudes toward the behavior and subjective norms.
Namely, they propose that one's sense of right and wrongs, as well as
one's beliefs surrounding moral obligation may also impact one's
intention. This value system is internalized independently from Fishbein and Ajzen's subjective norms.
Furthermore, social change may be generational rather than the sum of
individual change. TRA fails to capture and oversimplifies the social
processes of change and the social nature of the change itself: a model
in which people collectively appropriate and construct new meanings and
practice.
Additionally, the habituation of past behavior also tends to
reduce the impact that intention has on behavior as the habit increases.
Gradually, the performance of the behavior become less of a rational,
initiative behavior and more of a learned response. In addition,
intention appears to have a direct effect on behavior in the short term
only.
Besides, the analysis of the conceptual basis also raises concerns. It
is criticized that the model does not enable the generation of
hypothesis because of their ambiguity. The model focuses on analytic
truth rather than synthetic one, therefore the conclusions resulting
from those applications are often true by definition rather than by
observation which makes the model unfalsifiable.
The strengths of attitudes toward a behavior (social/personal) and
subjective norms also vary cross-culturally while the process by which
the behavior engaged remains the same. An example of this is shown in a
cross-cultural study on fast food choices, where people from Western
cultures were found to be more influenced by their prior choice of
restaurant than people from Eastern cultures.
This would suggest that people from different cultures weight
subjective norms and existing attitudes differently. A closer
examination of the cross-cultural communication process will benefit and
complete the understanding of theory of reasoned action.
Future Directions
According to Jaccard James, three directions are waiting for
further research in TRA. The first one is per-individual level. The
second area is a split-second situations, namely, instant
decision-making. The third one is multioption contexts. In other words,
how people perform when facing multiple alternatives should be stressed
in the future study.
