Sports spectator behavior: a test of the theory of planned behavior

The theory of planned behavior has been applied to sports and exercise behaviors. According to this theory, human intention to take action in a specific context is guided by three antecedents: attitude, subjective norm, and perceived behavioral control. Behavioral intention mediates the relationships between these three considerations and its ultimate performance. However, this theory has seldom been applied to the behaviors of spectators of sporting events. A sample of 269 volleyball spectators in Taiwan was studied to examine whether people's intention mediated their attitudes, subjective norms, and perceived behavioral control toward a given behavior, watching the 2010 Fédération Internationale de Volleyball World Grand Prix in Taipei. Regression analyses did not support behavioral intention as a mediator. This result is discussed in the context of planned behavior.     

Distinguishing Between Perceived Behavioral Control and Self-Efficacy in the Domain of Academic Achievement Intentions and Behaviors

We examined whether perceived behavioral control (PBC) and self-efficacy (S-E) can be distinguished empirically, and whether they make different contributions to the prediction of intentions and behavior. The behavioral criterion was performance in 3 high-school examinations. Measures of attitude, subjective norm, PBC, S-E, and intention were taken before the examinations. Grade achieved served as the behavioral measure. Factor analysis of items intended to measure PBC and S-E extracted 2 factors: confidence in ability to achieve the behavioral outcome, and belief that the outcome can be influenced by own efforts. Scores on these factors were labeled S-E and perceived control, respectively. Behavior was predicted better by S-E than by intentions, and intentions were more closely related to S-E than to attitudes, subjective norms, or perceived control.     

Moral Concerns and Consumer Choice of Fresh and Processed Organic Foods1

This study used the theory of planned behavior (TPB) to examine the impact of moral concerns on intention to buy organic apples and organic pizza. Initially, beliefs were elicited from a group of 30 people using a combination of the traditional TPB elicitation technique supplemented by direct questioning about emotions associated with the behavior. The questionnaire—which included measures of behavioral beliefs, attitudes, subjective norm, perceived behavioral control, and measures of moral norms (worded both positively and negatively)—was completed by 281 people. Multiple regressions showed that for both foods, the positive moral component added significantly to the prediction of intention, while negative ones did not. Also, affective attitude was a strong predictor of intention for both foods.     

A Typology of Stages of Adherence to Exercise Behavior: A Cluster Analysis

The aim of the study was to report the results of a cluster analysis of current exercise behavior and of intention to exercise in the next year. A sample of 22,286 individuals was recruited over 4 successive 3-month periods. Each individual was asked to complete a self-administered questionnaire assessing exercise behavior in the last 3 months and intention, attitudes, perceived social norms, and perceived behavioral control with respect to exercising in the coming year. The Beale's pseudo F statistic clearly suggests that there are 4 stages of adherence to exercise: unconcerned, ambivalent, optimistic, and active. Finally, MANOVAs and univariate tests indicated that the 4 clusters differed in attitude, subjective norm, and perceived behavioral control ( p < 0001). These results support the appropriateness of combining intention and behavior to identify stages of adherence to exercise.     

Physically active students' intentions and self-efficacy towards healthy eating

This study investigated intentions and self-efficacy of physically active university students towards healthy eating. The application of Planned Behavior theory has shown that attitudes, intention, perceived behavioral control, and subjective norms play an important role in shaping people's behavior. 96 students, who participated in physical activities, voluntarily completed the Questionnaire for the Planned Behavior Model and the Health Behavior Questionnaire. The former examines attitudes, intentions, perceived behavioral control, and the lately added attitude strength, and role identity towards the behavior factors. The latter assesses one's efficacy expectations towards healthy eating. The regression showed strong associations between the examined variables, signifying that attitudes, perceived behavioral control, and role identity could account for one's intention towards healthy eating behaviors. On the other hand, one's self-efficacy for healthy eating could be explained from the attitudes, intention, perceived behavioral control, and attitude strength held. Overall, systematic participation in physical activities appeared to be accompanied with a relatively healthier diet, while self-efficacy had a significant association with maintaining the healthy eating behaviors. Possible interpretations, limitations, and implications for health professionals are discussed.     

Intention of Chinese college students to use carsharing: An application of the theory of planned behavior

Carsharing originated in Europe and then expanded to developed countries such as the United States. With the revival and popularity of the “Sharing Economy,” carsharing has remarkably increased in China in recent years. Carsharing has increased convenience for individuals without private cars and is changing the traditional view of car ownership. Chinese college students are a large, highly educated group with low incomes and low rates of car ownership. Understanding the determinants of Chinese college students' intention to carshare is critical to promote carsharing services. In this research, an expanded version of the theory of planned behavior, which contains environmental concern, is the theoretical research framework. The model was empirically tested by using the questionnaire data of 356 college students from four universities in Qingdao, China. The results indicate that subjective norm and the perceived behavioral control are directly and positively associated with Chinese college students’ intention to use carsharing, and attitude and environmental concern have no direct correlation with the intention. Environmental concern has a significant direct effect on attitude, subjective norm, and perceived behavioral control. In addition, environmental concern indirectly impacts Chinese college students’ intention to use carsharing through subjective norm and perceived behavioral control. The findings yield practical insights for carsharing organizations and transportation planners. Based on these results, limitations of this study and suggestions for further research are discussed.     

Breast cancer: The intention to have a mammography and a clinical breast examination - application of the theory of planned behavior

Abstract

The purpose of these cross sectional studies was to identify the psychosocial factors explaining women's intention to have a mammography within the next two years and their intention to have a clinical breast examination (CBE) by a professional within the next year. Two random samples of women aged 40–69 years (n_a = 354, n_b = 344) completed a self-administered questionnaire that investigated theoretical constructs of the theory of planned behavior. The results of structural equation modeling showed that subjective norms and perceived behavioral control explained 81 % of the variance in intention of having a mammography. Sixty-five percent (65%) of the variance in intention of having a CBE was explained by attitude and perceived behavioral control. In conclusion, women need to be better informed, have better skills to overcome psychological and physical barriers in performing preventive breast behaviors, and promotion of preventive breast cancer methods should consider people significant for women.     

Online purchases in an Infocomm sophisticated society.

This paper presents a preliminary investigation of attitude and intention in relation to online shopping in Singapore. Singaporeans display high levels of Infocomm proficiency, the result of many intense government initiatives to transform the country into an Intelligent Community. Does this Internet embracing environment enhance attitude and intention to online shopping? This study considers the links between personal consequences, subjective norms, behavioral control, and personal innovativeness with attitude and intention among Singaporeans. It uses a model based on the Theory of Planned Behavior and makes some initial comparisons of its findings with those of existing studies. The effects of behavioral control and intention on actual purchase behavior are not investigated. Findings permit the tentative proposition that level of Infocomm knowledge impacts on attitude and intention.     

Drivers' compliance with speed limits: an application of the theory of planned behavior

The theory of planned behavior (TPB; I. Ajzen, 1985) was applied to drivers' compliance with speed limits. Questionnaire data were collected for 598 drivers at 2 time points separated by 3 months. TPB variables, demographic information, and self-reported prior behavior were measured at Time 1, and self-reported subsequent behavior was measured at Time 2. In line with the TPB, attitude, subjective norm, and perceived control were positively associated with behavioral intention, and intention and perceived control were positively associated with subsequent behavior. TPB variables mediated the effects of age and gender on behavior. Prior behavior was found to moderate the perceived control-intention and perceived control-subsequent behavior relationships. Practical implications of the findings for road safety and possible avenues for further research are discussed.     

The influence of self‐efficacy,subjective norms,and risk perception on behavioral intentions related to the H1N1 flu pandemic: A comparison between Korea and the US

This study examined the extent to which individualism‐collectivism moderates the relative effects of agency control beliefs (i.e., self‐efficacy), social norms (i.e., subjective norms), and risk perception (perceived vulnerability and perceived severity) on behavioral intention to engage in self‐protection behavior in the context of the H1N1 flu pandemic. Using multistage stratified sampling, the present study sampled people from the US (n = 399) and Korea (n = 500), two countries that have been found to be prototypical of individualistic and collectivistic national cultures, respectively. Consistent with the contrast between individualism and collectivism, the results of moderated regression analyses showed that intrapersonal control beliefs (i.e., self‐efficacy) and risk perception (i.e., perceived severity) had stronger effects on behavioral intention in the American sample than in the Korean sample, whereas social norms (i.e., subjective norms) had a stronger predictive power for the Korean sample than for the American sample. Overall, the findings contribute to health and risk studies by specifying which aspects of risk perceptions or beliefs are affected by national culture and how this translates into cross‐national variations in health risk behavioral intention.     

A Tale of Two Cities: Predicting Homeless People's Uptake of Outreach Programs in London and New York

Two studies involved structured interviews with 203 homeless people to examine the impact of sociodemographic variables, prior behavior, and the theory of planned behavior (TPB) variables, attitudes, subjective norms, perceived behavioral control, and intention, on uptake of outreach services. Study 1 was conducted in London, and Study 2 involved a comparable sample in New York. In line with previous research, the psychological variables accounted for more variance than the sociodemographic variables, and there was no evidence that the effects of TPB variables were moderated by sociodemographics. In London intentions and behavior were most affected by perceived control and subjective norms. In New York they were most affected by perceived control and attitude. These differences may be attributable to different institutional structures and opportunities for service uptake in the two cities. Sensitivity of the TPB to social context and implications for intervention strategies are discussed in light of these differences.     

Exploring psychological factors of mobile phone use while riding among motorcyclists in Vietnam

Mobile phone use while riding is one of the five most common risky behaviors of motorcycle riders in Vietnam. This study investigated motorcyclist’s mobile phone use while riding intention and behavior based on the extended Theory of Planned Behavior (TPB) framework. Based on this framework, attitude, subjective norm, perceived behavioral control, habits, and health motivation underlying the rider’s mobile phone use while riding intentions and behavior were included in a questionnaire and captured by direct and indirect measurements. Small-displacement motorcycle riders (N = 291) completed the extended TPB based questionnaire. An exploratory factor analysis technique identified the selected factors (e.g., attitude, habit, etc.). Moreover, Structural Equation Modeling results showed moderate to good fits to the observed data. Therefore, the results supported the utilization of extended TPB framework in identifying factors of mobile phone use while riding intention and behavior. Specifically, negative attitude, perceived behavioral control, and mobile phone use while riding habit related to the intention to use a mobile phone while riding of small-displacement motorcyclists. Meanwhile, habit and behavioral intention related to the behavior to use a mobile phone while riding of small-displacement motorcycle riders. Especially, the correlation between behavioral intention and self-reported behavior was very strong. This finding embraced previous research indicating that intention was a major motivational component of behavior. Based on the results, safety intervention implications for small-displacement motorcycle riders were discussed.     

General Beliefs and the Theory of Planned Behavior: The Role of Environmental Concerns in the TPB

This study tested whether the theory of planned behavior (TPB; Ajzen, 1985 ) could explain people's intention to use a park-and-ride facility (transferium) in Groningen, The Netherlands. We extended the TPB by including egoistic, altruistic, and biospheric concerns. A questionnaire study was conducted among 218 respondents who regularly visit the center of Groningen for work or shopping. Environmental concerns were directly related to attitudes toward using the transferium. However, the 3 types of concerns were not directly related to intention to use the transferium. Furthermore, positive attitudes, positive subjective norms, and high perceived behavioral control toward the use of the transferium were related to stronger intention to use the transferium. Limitations and practical implications of the study are discussed.     

Predicting adolescent pedestrians’ behavioral intentions to follow the masses in risky crossing situations

Adolescent pedestrians are a major population at risk of being killed or injured in traffic accidents, especially in developing countries. In the current study, we examined the effects of age, gender, sensation seeking, and conformity tendency on Chinese adolescent pedestrians’ intention to cross the road against a traffic signal. A sample of 510 adolescents, aged 12–19 years, completed a series of questionnaires comprising (1) a demographic questionnaire, (2) scales which measured their tendency towards social conformity and sensation seeking, and (3) a questionnaire based on the Theory of Planned Behavior (TPB), which measured their intention to cross the road in two different traffic scenarios. One scenario depicted a situation where the crossing was consistent with other pedestrians’ behavior (Conformity scenario). In the second scenario, the road crossing was inconsistent with other pedestrians (Non-conformity scenario). Along with behavioral intentions, attitudes towards the behavior, subjective norms, perceived behavioral control, anticipated affect, moral norms, and perceived risk were also assessed. In general, adolescent participants reported greater likelihood in crossing the road when other pedestrians were crossing the road as well (Conformity with the masses) and adolescents in middle school were more likely to cross than those in high school. A hierarchical regression model explained 30% of the variance in behavioral intention in the Non-conformity scenario and 40% of the variance in the Conformity scenario. For both scenarios, attitude, subjective norm, perceived behavioral control, and anticipated affect emerged as common predictors. The theoretical and practical implications for these results are discussed.     

Predicting Zimbabwean women's ability to tell their partners to use condoms.

The effectiveness of AIDS education may depend on the development of models that predict and explain HIV prevention behavior. In this study, the aim was to test Fishbein and Ajzen's theory of reasoned action model in predicting women's capacity to tell their partner to use condoms. The basic theory pertains to the relationship of 1) attitude toward behavior and 2) the subjective norms to behavior; further refinements reflect factors such as 3) perceived behavioral control or self-efficacy, 4) and perceived barriers. A sample was drawn of 123 female first-year teacher trainees in Harare, Zimbabwe, in late 1990; a self-administered questionnaire was distributed and returned. 72% of the respondents were sexually experienced. The mean age of the entire sample was 24 years. The results of the multiple linear regression indicated that the model was able to predict were F(2,74)=32.81, p.0001. 47% of the variance was explained by this Fishbein model. Attitude toward behavior was significantly associated with the intention to tell one's partner to use condoms (beta = .60, p .05). Subjective norms were not significant (beta = .15, p .05). Perceived behavioral control and perceived barriers were also not significantly associated with the intention to tell one's partner to use condoms. A caveat was that the subjective norm was measured by only one item, and an improved conceptualization and measurement of this construct might have changed the relationship. The suggestion is that health educators should address women's underlying beliefs and attitudes about the benefits of telling their partners to use condoms. Future prospective studies will better delineate the relationship between attitude and behavior.     

Predicting Mothers' Intentions to Limit Frequency of Infants' Sugar Intake: Testing the Theory of Planned Behavior1

This study examines the ability of the Theory of Planned Behavior to account for mothers' intentions to limit the frequency of their infants' sugar consumption. One group of mothers (experimental) was exposed to a dental health education program designed to promote this behavior, the other (control) group was not. Each group of mothers was interviewed twice; the intervention was delivered to mothers in the experimental group immediately after their first interview. The interviews incorporated measures of the key constructs in the Theory of Planned Behavior (attitudes to behavior, subjective norms, perceived behavioral control, and behavioral intentions). Results indicated that the addition of perceived behavioral control resulted in small but significant increments in the amount of explained variance in intentions, thereby supporting the theory. Although the change in intentions to perform the advocated behavior was not significantly greater in the experimental group than in the control group, there was a significant change in attitudes to the behavior in the experimental group but no such change in the control group. Moreover, amount of change in behavioral intentions was significantly correlated with amount of change in attitudes, but not with amount of change in subjective norms or perceived behavioral control. Analysis of behavioral beliefs indicated that the attitude change reflected a change in a specific behavioral belief that was targeted in the intervention. Further analyses focused on the role played by direct experience of the behavior and show that such experience tended to enhance the role of perceived behavioral control in intention formation, apparently because mothers who have older children have discovered that they have relatively little control over frequency of child's sugar consumption. The implication of these results for the Theory of Planned Behavior are discussed.     

Antecedents and moderators of behavioral intention: differences between U.S. and Taiwanese students

The purpose of this study was to investigate the relative influence of attitude toward the act, subjective norm, and perceived behavioral control on consumers' purchase intention when consumers possess different levels of product knowledge (subjective and objective). The magnitude of the influence is compared across two different societies (U.S. and Taiwanese). U.S. (N = 295) and Taiwanese (N = 297) college students participated. The results showed that the relative importance of attitude toward the act, subjective norm, and perceived behavioral control in predicting purchase intention varied across consumers with different levels of product knowledge (subjective or objective) for the U.S. participants. However, the moderating effect of product knowledge was less profound for the Taiwanese participants.     

Evaluation of a planned behavior theory-based intervention programme to promote healthy eating

The objective of the study was to test the effectiveness of an intervention program based on the theoretical framework of the Theory of Planned Behavior, with the addition of attitude strength and role identity. The aim was to alter adolescents' healthy eating attitudes and behaviour. In the sample were 335 high school students, who were divided into intervention and control groups. The intervention lasted 12 weeks and included posters and lectures promoting healthy eating. The measures included a questionnaire assessing the hypothesis and a food frequency questionnaire which measured eating habits. Analysis showed the intervention was effective in proving attitudes toward healthy eating and attitude strength, intention, perceived behavioral control, and healthy eating behaviour, but not effective in predicting subjective norms and role identity. Results provide evidence that intervention changed attitudes toward a behavior in a school setting.
