O artigo descreve o processo de busca de evidências de validade de conteúdo e de estrutura interna do modelo da Teoria do Comportamento Planejado (TCP) (Ajzen, 1991) aplicado à predição da intenção de compra de alimentos orgânicos no contexto brasileiro. O artigo apresenta o efeito que as atitudes, as normas subjetivas e o controle comportamental percebido exercem sobre a intenção de compra de alimentos orgânicos. A pesquisa seguiu o delineamento de levantamento online com amostragem por conveniência. A amostra contou com 705 consumidores brasileiros, maiores de idade e responsáveis ou parcialmente responsáveis pela compra de alimentos em suas residências. Na análise de dados foram utilizadas as técnicas de análise fatorial exploratória, confirmatória e de regressão linear múltipla hierárquica. O modelo da TCP explicou 58% da variação da intenção de compra de alimentos orgânicos. As atitudes (β=0,42), as normas subjetivas (β=0,30) e o controle comportamental percebido (β=0,35) são preditores da intenção de compra de alimentos orgânicos. Os resultados são relevantes para as organizações públicas e privadas envolvidas na cadeia de produção, de alimentos orgânicos que buscam subsídios teóricos e evidências científicas para justificar o desenvolvimento de mensagens voltadas à promoção da compra de alimentos orgânicos. As evidências encontradas corroboram a eficácia da TCP como modelo preditivo e apresentam resultados significativos que contribuem para o entendimento da formação da intenção de compra de alimentos orgânicos no contexto brasileiro.ABSTRACTThe article describes the search process for evidence of content validity and internal structure of the Theory of Planned Behavior model (TPB) (Ajzen, 1991) applied to the prediction of the intention to purchase organic food in the Brazilian context. The article presents the effect that attitudes, subjective norms and perceived behavioral control have on the intention to purchase organic foods. The research followed the design of an online survey with convenience sampling. The sample included 705 Brazilian consumers, of legal age and who are responsible or partially responsible for the purchase of food at their homes. In the data analysis, the techniques of exploratory and confirmatory factor analysis and hierarchical multiple linear regression were used. The TBP model explained 58% of the variation in the intention to purchase organic food. Attitudes (β = 0.42), subjective norms (β = 0.30) and perceived behavioral control (β = 0.35) are predictors of the intention to purchase organic foods. The results are relevant for public and private organizations involved in the organic food production chain that seek theoretical subsidies and scientific evidence to justify the development of messages aimed at promoting the purchase of organic foods. The evidence found corroborates the effectiveness of TPB as a predictive model and presents significant results that contribute to the understanding of the formation of the intention to purchase organic food in the Brazilian context.

This study extends the theory of planned behavior by taking communication factors into account to examine the determinants of pro-environmental behavioral intention in haze mitigation. Unlike other theory of planned behavior (TPB) extension studies, we shift the focus of inquiry from examining the mediating role of TPB variables to investigating the moderating role in promoting pro-environmental behavior. Using an online survey in China, the results indicated that attitude, subjective norms, perceived behavioral control, and attention to haze-related efficacy messages were positively associated with pro-environmental behavioral intention. Notably, attention to haze-related threat messages had no significant relationship with behavioral intention. Moreover, moderation analyses revealed that the interaction effects between attention to efficacy messages and attention to threat messages on behavioral intention vary among people with different attitude, subjective norms, and perceived behavioral control. Theoretically, this study contributes to the literature of the TPB by analyzing its moderating role in promoting behavior change. Findings from this study suggest the importance of disseminating distinctive media messages to audiences with different personality traits, which is beneficial for practitioners to tailor specific messages in environmental campaigns.

The purpose of this study was to examine the utility of the theory of planned behavior (TPB) in explaining employers’ hiring intentions of people who are blind or visually impaired (B/VI). Participants were 388 hiring managers who completed an online survey that included the four TPB construct measures (attitudes, subjective norms, behavioral control, and intent to hire). Confirmatory factor analysis (CFA) was used to determine the suitability of the measurement model, and structural equation modeling was used to test the structural model. The proposed TPB structural model provided good data fit; attitudes about productivity, subjective norms, and perceived behavioral control accounted for more than 61% of the variance in intent to hire people who are blind. Attitudes about productivity of a blind employee had the strongest relationship with intent to hire, followed by subjective norms and perceived behavioral control. Rehabilitation professionals who work with B/VI individuals should educate employers about how this population can perform the employers’ jobs to improve attitudes about productivity. They should consider employers’ subjective norms and perceived behavioral control, which could be influenced by providing disability awareness presentations to company employees and maintaining a relationship with employers, thus enabling employers to have access to qualified applicants.

Using the extended theory of planned behavior, this study examined individuals’ cognitive and psychological determinants of their intentions to donate to nonprofit organizations (NPOs) with either a positive or negative chief executive officer (CEO) reputation. With the use of online survey data (n = 371), the similarities and differences in the relationships between the determinants were analyzed for the two NPO CEO reputations. To verify the hypotheses, multiple regression was used to analyze the data. The results reveal that for NPOs with positive CEO reputations, subjective norms, perceived behavioral control, moral norms, past behavior, and identification had positive effects on the intention to donate. In contrast, for NPOs with negative CEO reputations, subjective norms and identification had positive effects on the intention to donate. Attitude toward the NPO was not related to donation intentions regardless of the CEO’s reputation. These findings suggest the need for strategies to increase the public’s intentions to donate to problematic NPOs with negative reputations. Additionally, a strategy to further strengthen the intention to donate in the case of a positive CEO reputation is proposed. Theoretical and managerial implications of the results are also discussed, highlighting important considerations for CEO reputations and NPO management in the short and long terms.

Graduate students have become the driving force of scientific research at Chinese universities. Therefore, further work is needed to understand what influences postgraduate students' academic integrity. Using the theory of planned behavior, this study investigated the relationships between postgraduates' attitude toward academic integrity, social norms (subjective, descriptive, and moral), perceived behavioral control, and intentions, and examined the moderating role of social identity in the relationship between social norms and intentions. We conducted a survey with 1,256 Chinese biomedical postgraduate students, and analyzed the data with structural equation modeling. The results show that attitude, subjective norms, descriptive norms, and perceived behavioral control influenced students' academic integrity-related behavioral intentions. The model explained over half of the variance in intentions, indicating that attitude, subjective norms, descriptive norms, and perceived behavioral control were the main variables influencing academic integrity-related behaviors. The theory of planned behavior can be applied in research on postgraduates' academic integrity.

Purpose This paper aims to examine travelers` behavioral intention of traveling in the period of coronavirus by employing the theory of planned behavior. The framework incorporates attitude, subjective norms, perceived behavioral control and a very crucial construct, i.e. perceived risk, as per the current critical scenario of COVID-19. Design/methodology/approach Data was collected using a survey instrument on the internet by posting the questionnaire link over social network web pages of online traveling websites. The data was analyzed using structural equations modeling with AMOS 22.0 and SPSS software, and the proposed hypotheses were statistically tested. The sample under consideration constitutes 417 responses. Findings Empirical findings suggest that attitude, perceived behavioral control and perceived risk are significant for predicting behavioral intention while subjective norms do not. And these variables explained about 35 percent of the variance in behavioral intention of traveling in the period of coronavirus. Research limitations/implications This study can benefit travelers, tourism and hospitality industry, governments, aviation industry and other relevant organizations as this paper offers the latest updates and essential information regarding traveler`s intention of traveling in the period of coronavirus. The study mainly focuses on India, so the generalizations of results to other countries are unwanted. Originality/value The primary value of this paper is that it tested the theory of planned behavior by incorporating perceived risk in the context of COVID-19. To the best of authors’ knowledge, in Indian context, there is no study which has tested the TPB by adding perceived risk in explaining the Indian citizens’ behavioral intention of traveling in the period of Coronavirus.

The purpose of this paper is to investigate the entrepreneurial intention of university students using the Theory of Planned Behavior (TPB) and parents' occupation. A questionnaire based survey was employed for the data collection. A total of 1244 students participated in the survey. The sample was a convenience one given that the resources available were limited. The size of the sample allows us to proceed with reliable statistical analyses and produce valid conclusions. The findings of our research showed that perceived behavioral control, subjective norms, attitude and parents' occupation are important variables influencing entrepreneurial intention. The variable that affects entrepreneurial intention the most is attitude. The findings led support to the theory and the hypotheses proposed. These findings indicate that the recommended model can be used to explain a large part of variation in entrepreneurial intention. This study, contributes to the entrepreneurial intention literature providing empirical evidence to help formulate policies encouraging university students' entrepreneurship practices, attracting the interest of both educators and policy makers. This evidence will become increasingly important, as research in the field of entrepreneurship continues to place models of entrepreneurial intentions at the center of our understanding of the entrepreneurial process. Future studies could investigate the validity of the findings reported here, in different contexts using more variables, not included in this study and inquire the potential existence of latent variables which may be confounding the relationships discussed in this paper.
