Using a theoretical framework to determine adults' intention to vaccinate against pandemic swine flu in priority groups in the UK

Vaccination is key in controlling influenza pandemics. Ways of identifying determinants that influence the decision to be vaccinated need to be understood in order to optimize vaccination rates. Therefore, this study aimed to predict intention to be vaccinated against swine flu in priority groups in the UK. An extension of the Theory of Planned Behaviour (TPB) provided the theoretical framework for the study. The study population consisted of 134 adults from the UK who were in vaccination priority groups, either because they were healthcare professionals or in 'other' vaccination priority groups (e.g. due to having a chronic illness, being pregnant). Data were collected from 30 October 2009 (just after the swine flu vaccine became available in the UK) until 31 December 2009. The main outcome of interest was intention to be vaccinated against swine flu. Overall, intention was not high. Healthcare professionals were less likely to intend to be vaccinated compared with other priority groups. The theoretical framework was a powerful predictor of intention, explaining 70% of the variance in intention. The most important parts of the model were the demographic variables and original TPB which explained 66% of the variance in intention, with other variables (extended TPB/Health Belief Model) accounting for an extra 4% of the variance in intention. This is in contrast to results from the general population. The study results provide a useful framework on which to base future interventions for improving uptake of pandemic flu vaccination. These interventions need to be targeted at specific groups given the different results of the priority groups compared with the general population.

Intentions to participate in counselling among front-line, at-risk Irish government employees: an application of the theory of planned behaviour

ABSTRACT The study set out to examine intentions to engage in counselling among at-risk Irish government employees and the differential utility of two alternative theory of planned behaviour (TPB) models of behaviour to explain intentions to participate in counselling. Individuals (N=259) employed in a front-line, at-risk occupation for the Irish government completed a TPB-based questionnaire. Quantitative analyses revealed that participants held positive to neutral intentions to participate in counselling, irrespective of gender. The original TPB model explained 49.9% of variance in intentions whereas an alternative TPB model, splitting the perceived behavioural control (PBC) construct between its internal and external control components, explained a further 8.9% of variance. Furthermore, self-efficacy was found to be the strongest predictor of intentions. This study therefore supports the use of the TPB in understanding counselling-seeking behaviour.

Intention to pay conventional-hotel prices at a green hotel – a modification of the theory of planned behavior

Numerous studies have employed the theory of planned behavior (TPB) to understand customers’ behaviors in various fields, but none has tested and extended the theory to explain customers’ decision formation to pay comparable regular-hotel prices for a green hotel. This is the first study designed to test and modify the TPB by including environmental concerns, perceived customer effectiveness and environmentally conscious behaviors, which are critical in explaining eco-friendly consumer behaviors. Salient belief items were identified using an elicitation method (focus group and open-ended survey). A survey obtained 389 respondents. Confirmatory factor analysis indicated that measurement items for all study variables had an adequate level of reliability and validity. The findings from the structural equation modeling showed that the proposed model had a satisfactory fit to the data and better predicted hotel customers’ intention than the original TPB. The results also indicated that all antecedent variables of intention significantly contributed to forming the intention to pay conventional-hotel prices for a green hotel. Respondents were happy to have minor inconveniences, e.g. reusing towels and using recycled products, and were keen to learn about the positive environmental attributes of green hotels. Benefit awareness was shown to be important in customer decision-making.

An investigation of green hotel customers’ decision formation: Developing an extended model of the theory of planned behavior

The current study sought to extend the theory of planned behavior (TPB), which is rooted in the theory of reasoned action (TRA), to more comprehensively explain the formation of customers’ intention to revisit a green hotel. In particular, the extended TPB incorporates the critical constructs in the consumer behavior and marketing literature (i.e., service quality, customer satisfaction, overall image, and frequency of past behavior) into the original TPB model. Results of a structural analysis revealed that the new model provides a better fit with the data, and explains significantly greater amounts of variance in revisit intention in comparison to the TRA and TPB. Added constructs in the new model considerably contribute to improve our understanding of the complicated process of green hotel customers’ decision-making. In this study, all relationships appeared to be significant as conceptualized according to the theory. In addition, a mediating effect of satisfaction and attitude was found. The article includes discussions on theoretical and managerial implications.

It Certification Use by Hiring Personnel

This paper uses the theory of planned behavior (TPB) to explore the factors that affect hiring personnel's intention to use IT certification in the hiring process. It demonstrates the usefulness of adding Cognition and Affect as predictors of Attitude in this domain. Analysis by structural equation modeling indicated that all original TPB constructs, Attitude, Subjective Norm, and Perceived Behavioral Control, are significant in predicting behavioral intention, and that both Affect and Cognition significantly influence Attitude. These findings add to our understanding of IT certification usage in hiring decisions and provide support for the addition of Affect and Cognition in future TPB research.

Digital music services: consumer intention and adoption

In recent years, the popular channel to obtain record albums has shifted from purchasing compact discs to downloading MP3 files. In fact, digital music service (DMS), the industry that sells MP3 songs, has seen tremendous successes and is making hundreds of millions of dollars every year. However, few attempts have been made to understand the consumption behavior of this newly emerging market because it has its own characteristics that have made other behavioral models inapplicable. In this study, we surveyed college students, who are the most active in this market, concerning their DMS subscription behavior. A modified theory of planned behavior (TPB) model was used as the framework. This new model incorporates the technology acceptance model and a new construct, the perceived service quality, into the original TPB model. Based on the survey results, the present study depicts a model that explains subscription behavior and indicates that subjective norm has the most significant effect on the intention to subscribe. Also, features that potential subscribers found important are revealed. The results provide marketing implications for DMS providers and indicate possible direction for future studies.

The role of ethnic identity and perceived ethnic norms in the purchase of ethnical food products

The role of group and individual variables in the purchasing of ethnical food products was tested through an extended theory of planned behavior (TPB) model. A total of 100 Indian female immigrants, living in Rome, Italy, were administered a self-reported questionnaire measuring the classical TPB variables (attitudes, subjective norms, perceived behavioral control, behavioral intentions and self-reported behaviors) plus 3 additional variables: identification with the Indian ethnic group, perceived norms of the Indian ethnic group, and past behavior. Results confirmed that the new variables introduced are distinct from the original TPB components. As expected, variables at both the individual and group level play a role in predicting purchasing of ethnical foods products. Hierarchical multiple regressions showed that past behavior, ethnical identification, and perceived group norms explain an additional proportion of variance in intentions and self-reported behaviors, independently of attitudes, subjective norms and perceived control. A significant 2-way interaction between ethnical identification and perceived group norms was also detected: as predicted, the highest levels of ethnical food purchasing behavior were reported by high ethnical identifiers with stronger ethnical group norms, while the lowest levels were reported by low ethnical identifiers with weaker ethnical group norms. Theoretical and practical implications of results are discussed.

Testing the sufficiency of the theory of planned behavior: a case of customer dissatisfaction responses in restaurants

This study tested the sufficiency of both the Theory of Planned Behavior (TPB) and the extended TPB models by adding the variable of past behavior. In addition, the present study examined the mediating role of the TPB variables on the relationships between past behavior and customers’ intentions to engage in different types of dissatisfaction responses (i.e., voice, negative word-of-mouth communication, and exit). Results of the study demonstrated the strong predictive power of the original TPB mode but the inclusion of past behavior did not significantly improve the predictability of the three dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by TPB variables. In the contexts of negative word-of-mouth communication, the effect of past behavior on intention was mediated by attitude. Meanwhile, both subjective norm and perceived behavioral control mediated the relationship between past behavior and the intention to engage in voice behavior.

Self-Identity and the Theory of Planned Behavior in the Prediction of Health Behavior and Leisure Activity

To compare the predictive power of an expanded model of the Theory of Planned Behavior (TPB) with that of the original TPB, two studies were conducted in which, in addition to the classical variables of the TPB model (such as attitudes, subjective norms, and perceived behavioral control), variables concerning self-identity were also taken into account. Two independent samples of Italian subjects (N 1 =288, N 2 =188) were recruited to study behavioral intentions concerning the domains of leisure activity (attending Latin American dance classes) and health behavior (purchasing of low-fat food) in relation to variables derived from the TPB and from the Identity Theory. Structural equation modeling showed that identity variables contributed significantly and independently to the explanation of behavioral intentions beyond traditional TPB variables.

Extending the Theory of Planned Behavior: Predicting the Use of Public Transportation1

An expanded version of the theory of planned behavior (TPB) was used to predict and explain public transportation use. A pre‐post design was used to examine changes in university students’ bus ridership after the implementation of a universal bus pass (U‐pass) program. Bus ridership significantly increased after the U‐pass was implemented, and associated changes in attitudes and beliefs about transportation modes were found. In both phases, students’ public transportation use was well predicted by the original TPB. However, 2 additional constructs—a descriptive norm, and the interaction between intention and perceived behavioral control—significantly improved prediction in both phases of the study. These constructs might be useful additions to the original TPB, at least in this behavioral domain.

A theory of planned behavior-based structural model for breast-feeding.

Breast-feeding is the recommended method of infant feeding because it is clearly associated with health benefits for infants and their mothers. Yet, many women who initiate breast-feeding fail to meet their own personal goals or recommended standards for duration of breast-feeding. To refine a Theory of Planned Behavior (TPB)-based structural model for explaining variability in breast-feeding intention and duration. The study design was prospective, multicorrelational, and longitudinal. Out of the total sample of 635 women, 602 mothers of healthy, full-term infants provided complete datasets over the entire course of their breast-feeding experience and these datasets were used in the modeling analyses. Simultaneous multisample analysis of covariance structures was used to develop the model. The resulting TPB for Breast-Feeding (TPB-BrF) describes the rational, motivational processes of the original TPB, but reconfigures the relationships among them, for homemakers (TPB-BrF/H), women employed half-time or less (TPB-BrF/EL), and women employed more than half-time (TPB-BrF/EM). Mothers' early postpartum ratings of adequacy of milk supply and stimulus conditions of maternal education and breast-feeding knowledge were included in the TPB-BrF to better explain breast-feeding outcomes. Model complexity increased with employment effort. The TPB-BrF is a comprehensive, theoretically based, empirically verified model that can serve as a useful heuristic for understanding the personal motivational components of breast-feeding behavior.
