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.     

Predicting Intentions of Romantic Partner Abuse with the Theory of Planned Behavior

From the theory of planned behavior, attitudes, subjective norms, and perceived behavioral control were identified as predictors of intentions for verbal, physical, and sexual abuse toward romantic partners. Relationships among the three predictors across the three types of abuse were examined with responses from undergraduates involved in romantic relationships. The theory of planned behavior accounted for substantial variance associated with intentions to abuse romantic partners. Moreover, the components of the theory of planned behavior were differentially predictive of the three forms of abuse, which also varied by sex. A recommendation is that interventions should target different components of the theory of planned behavior depending on the type of abuse they are attempting to prevent.     

Application of the Theory of Planned Behavior to Recidivism: The Role of Personal Norm in Predicting Behavioral Intentions of Re‐Offending1

The study is a partial application of the theory of planned behavior (TPB) to the prediction of young offenders’ behavioral intentions to re‐offend. Participants were 152 young offenders who were randomly selected and who completed a self‐report questionnaire assessing the sociocognitive determinants of the TPB and personal norm. It was found that attitudes and perceived behavioral control are necessary factors for the prediction of intentions to re‐offend; while personal norm contributed significantly, yet marginally. The TPB provides a parsimonious way to predict behavioral intentions to re‐offend. Personal norm could be a variable that expands the model when it is applied to the prediction of young offenders’ behavioral intentions to re‐offend.     

Exploring Attitudes and Predicting Intentions: Profiling Student Debtors Using an Extended Theory of Planned Behavior

This study was designed to investigate application of a theory of planned behavior, including involvement and decision‐making style in predicting undergraduates' borrowing attitudes. We conducted interviews to explore antecedents of students' debt‐consumption/borrowing attitudes. We employed exploratory factor analysis to identify attitudinal dimensions utilized in hierarchical regression as independent variables. The results suggest students regard themselves as good money managers, but lack control over borrowing and debt. Combining involvement and decision‐making style as a style/involvement variable had a powerful mediating effect in predicting borrowing intention. Research suggests that grouping students, based on their involvement level with finance and decision‐making style, into debtor types offers opportunities for more understanding of their debt‐consumption intentions. Strategies are proposed for dealing with different debtor types.     

Predicting Intentions to Conserve Water From the Theory of Planned Behavior,Perceived Moral Obligation,and Perceived Water Right1

This study tested the explanatory power of Ajzen's (1991) theory of planned behavior (TPB), and a modified TPB model including perceived moral obligation (PMO) and perceived water right (PWR), to predict people's intentions to conserve water. The study had 244 government employees who participated. The TPB variables improved the prediction of intention to use less water, but were less successful in predicting intention to install water-efficient appliances. A significant interaction was found between attitude and subjective norm, suggesting that past studies have overlooked moderating effects in the TPB model. In addition to the TPB variables, PWR further improved the prediction of intention to install water-efficient appliances. Results also suggest that water-saving procedures should be differentiated into curtailment and efficiency procedures.     

An Application of the Theory of Planned Behavior to Exercise Among Older Adults1

One hundred five older adults enrolled in exercise classes were recruited from local YMCAs. Exercise behavior was measured 1, 3, and 9 months after beginning the exercise class. Intentions were not a significant predictor of exercise behavior, probably because of a lack of variance; most people intended to exercise. The direct measures of attitudes, subjective norms, and perceived behavioral control, however, explained 9% of exercise behavior at 1 month. They did not significantly explain behavior at 3 and 9 months. When the indirect measure of subjective norms explained 18% of exercise behavior at 1 month. The indirect measure of perceived behavioral control accounted for 27% of the variance at 1 month and 10% at 3 months.     

Predictors of Young People's Charitable Intentions to Donate Money: An Extended Theory of Planned Behavior Perspective

An extended theory of planned behavior (TPB) was used to predict young people's intentions to donate money to charities in the future. Students (N = 210; 18–24 years) completed a questionnaire assessing their attitude, subjective norm, perceived behavioral control (PBC), moral obligation, past behavior, and intentions toward donating money. Regression analyses revealed that the extended TPB explained 61% of the variance in intentions to donate money. Attitude, PBC, moral norm, and past behavior predicted intentions, representing future targets for charitable‐giving interventions.     

Alcohol Use During Pregnancy: An Application of the Theory of Planned Behavior1

The objective of this research was to apply the theory of planned behavior (TPB; Ajzen, 1988, 1991 ) to alcohol use during pregnancy. Of the pregnant women (N = 130) who participated in the study, over one third reported consuming alcohol (34.8%), and the greatest proportion were drinking 2 to 4 times per month (16.4%). Binary logistic regression was conducted, and the full TPB model was able to distinguish between drinkers and abstainers, explaining 57.1% to 77.1% of the variance in drinking behavior. The TPB provides insight into reasons behind the behavior and can be usefully applied, both as a screening tool to identify pregnant women drinking during pregnancy and as an avenue for intervention work.     

Predicting Intentions to Use Condoms: A Meta-Analysis and Comparison of the Theories of Reasoned Action and Planned Behavior1

A meta-analysis was conducted on 23 psychosocial predictors of intentions to use condoms. Data from 67 independent samples were included in the review. Findings demonstrated that demographic, sexual experience, and personality variables had small average correlations with intentions. Knowledge about HIV/AIDS and perceptions of the threat of disease were also weakly related to decisions about using condoms. Attitudes and subjective norms from the theory of reasoned action, on the other hand, demonstrated medium to strong effect sizes. Two components of social influence not specified by the theory of reasoned action also received support. Evidence suggested that perceived behavioral control from the theory of planned behavior was a reliable predictor of behavioral intentions and explained variance over and above the effects of attitudes and subjective norms.     

Applicability of the Extended Theory of Planned Behavior in Predicting Job Seeker Intentions to Use Job‐Search Websites

Although use of the Internet for job searching is rapidly increasing, the motivations for using electronic recruitment (e‐recruitment) services by job seekers have seldom been addressed. Derived from the extended theory of planned behavior, this study develops a research model for the empirical examination of factors affecting job seeker intentions to use job‐search websites. Utilizing data collected from 174 participants in Taiwan, various relationships in the research model are tested using structural equation modeling approach. The results showed that job seeker attitude, subjective norm, and perceived behavioral control significantly affected their intentions to use job‐search websites. Also, perceived usefulness and perceived ease of use showed a significant effect on attitude, interpersonal influence on subjective norm, and perceived ease of use and self‐efficacy on perceived behavioral control. However, external influence was found to be an insignificant predictor of subjective norm. In addition to providing further insight into the factors that influence job seeker intentions to use job‐search websites, this study offers valuable suggestions for subsequent research and practitioners investigating the use of e‐recruitment services.     

The Proposition of a General Version of the Theory of Planned Behavior: Predicting Ecological Behavior1

The present paper explores whether the theory of planned behavior (TPB) must abandon the notion that perceived behavioral control (PBC) has a direct influence on behavior. In a cross‐sectional survey of 895 Swiss residents, our hypothesis was tested by means of structural equation models. Applied specifically, PBC turned out to be a significant direct predictor of one's performance. A general version of the TPB based on aggregated measures, however, revealed PBC's direct influence on behavior to be nonsignificant and, presumably, a non‐universally applicable and thus nongeneralizable part of the theory. Intention determined 51% to 52% of people's ecological behavior, which supports the claim of a strong attitude‐behavior relation. Attitude, subjective norms, and PBC, the 3 TPB components, account for 81% of intention's variance.     

Stress and the Theory of Planned Behavior: Understanding Healthy and Unhealthy Eating Intentions

Unhealthy and healthy eating intentions are predicted in a sample of 154 university students by the theory of planned behavior variables, in interaction with life stress. Specifically, subjective norms and perceived behavioral control (PBC) are shown to interact with life stress in relation to intentions to eat unhealthy foods, such that at high stress, the effects of subjective norms and PBC are attenuated. Implications are discussed for studies involving the planned behavior model and the study of life stress and unhealthy eating, for the theory of planned behavior more broadly, as well as for interventions targeting university students' eating intentions.     

Even with the Best of Intentions: Paternal Involvement and the Theory of Planned Behavior

Implicit in much of the fatherhood discourse is the assumption that if fathers want to take an active role in their children's lives, they could and would do so. While research has highlighted the factors associated with fathers' involvement, very few, if any, of these studies have been guided by a theory that accounts for both fathers' involvement intentions and their ability to follow through on those intentions. The theory of planned behavior and its emphasis on attitudes, the beliefs of significant others, and whether one has control over engaging in behavior is a conceptual fit to respond to questions related to the complex nature of paternal involvement. Using data from the Fragile Families and Child Well‐being Study, the purpose of this study was to test the utility of the theory of planned behavior in predicting fathers' involvement intentions and reports of involvement. The results revealed that the theory of planned behavior can be useful in examining paternal involvement and should be used in future research to enhance the fatherhood literature.     

Intentions to Cheat: Ajzen's Planned Behavior and Goal-Related Personality Facets

This study sought to test antecedents to college students’ intentions to cheat by utilizing Ajzen's (1991 Ajzen, I. (1991). The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50(2), 179–211. doi:org/10.1016/0749-5978(91)90020-T[Crossref], [Web of Science ®] , [Google Scholar]) theory of planned behavior (TPB), and four goal-related personality facets. Those facets were behavioral approach, behavioral inhibition, need for achievement–hope of success, and need for achievement–fear of failure. As hypothesized, perceived friends’ and parents’ attitudes toward academic dishonesty (two subjective norms) and perceived ease of cheating (perceived behavioral control) all positively predicted overall intentions to cheat. Perceived friends’ attitudes seemed to play a more influential role than perceived parents’ attitudes. Interestingly, male students reported greater parental acceptance of academic misconduct than female students reported. Among the personality facets, behavioral approach and need for achievement–hope of success were positive and negative predictors of cheating intentions, respectively. A more fine-grained examination of take-home assignments revealed that students considered them easier to cheat on and reported greater intentions to cheat on them in comparison to other forms of academic work (e.g., exams and papers). Also, need for achievement–fear of failure positively predicted intentions to cheat on take-home assignments, but not other cheating intentions. Implications and suggestions for future research are discussed.     

Ethical Intentions and the Theories of Reasoned Action and Planned Behavior1

This study compares the explanatory power of Fishbein and Ajzen's (1991) theory of reasoned action, Ajzen's (1975) theory of planned behavior, and a modified version of the theory of planned behavior, which includes a measure of moral obligation, to predict insurance agents' e]thical intentions toward their clients. Two hundred and forty-five insurance agents in the U.S. were sent surveys, and with 59% of them responding, results suggest that the modified version of the theory of planned behavior best explains agents' e]thical intentions. Theoretical considerations and suggestions for future research, highlighting the perceived behavioral control and moral obligation constructs, are provided.     

Intentions to Care for Children Orphaned by HIV/AIDS: A Test of the Theory of Planned Behavior

HIV/AIDS has added an unparalleled number of children to South Africa's orphan population. The theory of planned behavior (TPB) was used to investigate the decision-making processes of potential substitute caregivers of children orphaned by AIDS. Existing foster and adoptive parents ( n  = 175) completed a self-report postal survey. Of the sample, 76.0% reported willingness to care for an HIV-negative child and 62.2% an HIV-positive child. Analyses of the theory's components reveal contradictory and disappointing results. While the theory is most useful in conceptualizing the factors that bear on fostering and adoption, the current study suggests that the TPB is limited in its ability to address the complexity of decisions that attend fostering and adoption of children orphaned by HIV/AIDS.     

Explaining Unit Nonresponse in Online Panel Surveys: An Application of the Extended Theory of Planned Behavior1

Unit nonresponse is a critical issue in survey methodology. The purpose of this paper is to understand better the mechanisms that underlie unit nonresponse; i.e., the individual's decision to participate in online panel surveys. Based on the theory of planned behavior (TPB), the determinants of unit nonresponse are one's attitude toward participating in online panel surveys, the subjective norm, and perceived behavioral control. Using a student sample at the University of Berne (N = 308), our results show only a marginal effect of the intention to predict participation behavior, and no effect was found for perceived behavioral control. Instead, additional explanatory variables (e.g., moral obligation, frequency of past behavior) led to a better explanatory power of the TPB.
