OBJECTIVE: The aim of this study was to develop an index for oral hygiene behavior (OHB) and to examine potential predictors of this actual behavior based on the theory of planned behavior (TPB). Measures of oral health knowledge (OHK) and the expected effect of having healthy teeth on social relationships were included too.MATERIAL AND METHODS: Using an Internet questionnaire, 487 participants were asked about actual OHB, attitudes (ATT), social norms (SN), perceived behavioral control (PBC), OHK, and expected social outcomes (ESO). Based on a Delphi method involving oral health professionals, a new index for OHB was developed, including tooth brushing, interdental cleaning, and tongue cleaning.RESULTS: Regression analysis revealed that the TPB variables (ATT, SN, and PBC) and OHK explained 32.3% of the variance in self-reported OHB.CONCLUSION: The present findings indicate that socio-psychological consequences play a role in oral health care.

This study examines the motives of employees to engage in workrelated social media use – i.e. the use of personal social mediaaccounts to communicate about work-related issues. The theory ofplanned behavior (TPB) was used to explain this behavior.Because social media can enable users to express theiridentities, social identity expressiveness and self-identityexpressiveness were added to the TPB model. Through an onlinequestionnaire, using purposive sampling technique, 514 Dutchemployees were asked about their social media use and motivationto do so. We used structural equation modelling (SEM) to testour hypotheses. Results indicate that these identity constructsenhance the predictive ability of the TPB. As such, workrelationsocial media use is likely to take place spontaneouslyrather than deliberately and consciously planned.

Recently Leroy et al. (2008) tested if the Theory of Planned Behavior (TPB) predicts exit behavior of entrepreneurs: liquidation or transfer. He added the purchasers view to the TPB: firm viability and intangible assets. We retested Leroy et al. hypotheses on a more refined dataset of 136 firms in another country. Our study confirms the finding of Leroy et al.. We find though that the firm’s viability, the intangible assets and the client base are better predictor than intentions from the TPB.

Reducing food waste at the consumer level is a critical component of the U.N. sustainable development goals, yet consumer behavior in this domain remains complex and multifaceted. This study extends the Theory of Planned Behavior (TPB) to develop a comprehensive model of food waste behavior in a developed economy, integrating both cognitive and structural factors that influence consumer decisions. Using survey data from 309 U.S. households, we empirically test the impact of retail strategies, perceived utilitarian food waste benefits, and holiday habits on food waste behavior. The findings reveal that retail strategies, such as promotions and packaging tactics, encourage over-purchasing, contributing to increased waste. Additionally, consumers who perceive benefits in discarding food–such as making space for fresher items or avoiding the effort of meal planning–exhibit higher food waste tendencies. Seasonal consumption patterns further amplify waste, as holiday-related shopping habits drive excessive food acquisition. These results underscore the need for interventions that address both individual decision-making processes and broader market-driven influences. By integrating structural and habitual determinants into the TPB framework, this study enhances the theoretical understanding of food waste behavior and offers practical implications for policymakers and retailers seeking to reduce consumer-level food waste.

A cornerstone of inclusive education is teacher’s readiness to respond adequately to different educational needs of students in their diverse classroom. Differentiated instruction, referring to the process by which teachers carefully monitor students’ needs and progress, and adapt their instruction according to these differences, is a means to meet the needs of students of different levels. High-quality differentiated instruction is a complex process for teachers which needs careful preparation. This makes teachers’ intentions relating to differentiated instruction particularly relevant. In this article we compare two theoretical models to explain teachers’ intentions to differentiate: the Theory of Planned Behavior (TPB) and Self-determination theory (SDT). Secondary school teachers (n = 180) responded to a questionnaire in which we measured their intentions and predictor variables relating to both of the theoretical models. Linear regression showed that both the TPB as well as the SDT model significantly predicted teachers’ intentions (p < .01), but that the TPB model showed a better fit with the data (48 versus 32% explained variance). We conclude that in addition to the factors included in the TPB, autonomy might be a relevant factor in explaining teachers’intentions.

The hospitality industry contributes significantly to global climate change through its high resource consumption and emissions due to travel. As public pressure for hotels to develop sustainability initiatives to mitigate their footprint grows, a lack of understanding of green behavior and consumption of hotel guests hinders the adoption of effective programs. Most tourism research thus far has focused on the ecotourism segment, rather than the general population of travelers, and while research in consumer behavior shows that locus of control (LOC) and guilt can influence guests’ environmental behavior, those factors have not been tested with consideration of the subjective norm to measure their interaction and effect on recycling behavior. This study first examines the importance of internal and external LOC on factors for selecting hotel accommodation and the extent of agreement about hotel practices and, second, examines the differences in recycling behavior among guests with internal versus external LOC under levels of positive versus negative subjective norms and feelings of low versus high guilt.

BACKGROUND: Older adults want to preserve their health and autonomy and stay in their own home environment for as long as possible. This is also of interest to policy makers who try to cope with growing staff shortages and increasing health care expenses. Ambient assisted living (AAL) technologies can support the desire for independence and aging in place. However, the implementation of these technologies is much slower than expected. This has been attributed to the lack of focus on user acceptance and user needs.OBJECTIVE: The aim of this study is to develop a theoretically grounded understanding of the acceptance of AAL technologies among older adults and to compare the relative importance of different acceptance factors.METHODS: A conceptual model of AAL acceptance was developed using the theory of planned behavior as a theoretical starting point. A web-based survey of 1296 older adults was conducted in the Netherlands to validate the theoretical model. Structural equation modeling was used to analyze the hypothesized relationships.RESULTS: Our conceptual model showed a good fit with the observed data (root mean square error of approximation 0.04; standardized root mean square residual 0.06; comparative fit index 0.93; Tucker-Lewis index 0.92) and explained 69% of the variance in intention to use. All but 2 of the hypothesized paths were significant at the P<.001 level. Overall, older adults were relatively open to the idea of using AAL technologies in the future (mean 3.34, SD 0.73).CONCLUSIONS: This study contributes to a more user-centered and theoretically grounded discourse in AAL research. Understanding the underlying behavioral, normative, and control beliefs that contribute to the decision to use or reject AAL technologies helps developers to make informed design decisions based on users' needs and concerns. These insights on acceptance factors can be valuable for the broader field of eHealth development and implementation.

Industrial Symbiosis Networks (ISNs) consist of firms that exchange residual materials and energy locally, in order to gain economic, environmental and/or social advantages. In practice, ISNs regularly fail when partners leave and the recovery of residual streams ends. Regarding the current societal need for a shift towards sustainability, it is undesirable that ISNs should fail. Failures of ISNs may be caused by actor behaviour that leads to unanticipated economic losses. In this paper, we explore the effect of these behaviours on ISN robustness by using an agent-based model (ABM). The constructed model is based on insights from both literature and participatory modelling in three real-world cases. It simulates the implementation of synergies for local waste exchange and compost production. The Theory of Planned Behaviour (TPB) was used to model agent behaviour in time-dependent bilateral negotiations and synergy evaluation processes. We explored model behaviour with and without TPB logic across a range of possible TPB input variables. The simulation results show how the modelled planned behaviour affects the cash flow outcomes of the social agents and the robustness of the network. The study contributes to the theoretical development of industrial symbiosis research by providing a quantitative model of all ISN implementation stages, in which various behavioural patterns of entrepreneurs are included. It also contributes to practice by offering insights on how network dynamics and robustness outcomes are not only related to context and ISN design, but also to actor behaviour.

In elite sports, a case is increasingly made for the structural inclusion of what we label as planned disruptions. These are structured and deliberate training activities whereby athletes are exposed to increased and/or changing demands under controlled circumstances. Despite the growing body of evidence in support of planned disruptions (Sarkar & Fletcher, 2017), there is a lack of knowledge on which strategies coaches use in an applied context and why they use them. The present study, therefore, aimed at exploring the different types of planned disruptions high-performance coaches use and the desired outcomes of these disruptions. To this end, thematic analysis (Braun, Clarke, & Weate, 2016) was used to analyze semistructured interviews with 9 talent development and elite-level coaches (M age = 42.9, SD = 8.3; 6 male, 3 female). Results indicated that coaches use a combination of 9 types of planned disruptions (i.e., location, competition simulation, punishments and rewards, physical strain, stronger competition, distractions, unfairness, restrictions, and outside the box). These strategies were used to familiarize athletes to pressure, create awareness, develop or refine personal resources, and promote team processes. Three additional themes emerged, namely, the surprise use of planned disruptions, periodization, and the impact on personal relationships. The findings in the present study can guide further applied and theoretical explorations of the use of planned disruptions.

After the integration of research activities, universities of applied sciences (UASs) have formulated organisational strategies to foster connections between research and education (Daas et al., 2023). Scholars stated that the behaviour of employees within UASs influences ‘the direction and tempo in which the proposed aims are reached or resisted in the wider organisation’ (Griffioen & De Jong, 2017, p. 454). Thus, employees within UASs, such as academics and lower-level managers, play a key role in establishing research-education connections (Jenkins & Healey, 2005; Van der Rijst, 2009). A recent study has shown that academics and lower-level managers connect research and education through three types of behaviours: by involving aspects of research in education, by involving aspects of education in research, and by involving aspects of research and education equally, with the first type mentioned most often (Daas & Griffioen, in review). Similar patterns are observed in previous studies highlighting how education benefits from research rather than vice versa (Taylor, 2007). However, the beliefs underpinning this behavioural focus still remain unclear. Scholars have reported factors that could influence employees in connecting research and education, such as career stages, personal abilities and the availability of resources influencing how academics combine research and teaching tasks (Coate, Barnett & Williams, 2001; Shin, 2011), and research productivity and teaching beliefs influencing how academics integrate research in teaching (Hu et al., 2015; Magi & Beerkens, 2016). Despite the important value of these insights, these studies all focus on one (set of) behaviour(s) in connecting research and education instead of considering factors influencing behaviours in connecting research and education holistically. Moreover, most of these studies consider academics instead of managers. Therefore, the purpose of this study is to investigate the beliefs underpinning the behaviour of academics and lower-level managers in UASs in connecting research and education.To study the underpinning beliefs we applied the Theory of Planned Behaviour (TPB; Ajzen, 1991) as a theoretical lens. According to the TPB, a person’s behavioural intentions are shaped through three determinants (Ajzen, 1991). Behavioural beliefs (1) refer to a person’s conceptions about the expected positive/negative outcomes of practicing the behaviour. Normative beliefs (2) consist of a person’s conceptions about whether others approve/disapprove of practicing the behaviour. Control beliefs (3) are a person's conceptions about the presumed factors that could enable/hinder in practicing the behaviour. The research question is: Which behavioural, normative and control beliefs underpin the behaviour of academics and lower-level managers in connecting research and education?
