Theory Of Planned Behavior Variables Research Articles

Application of the theory of planned behavior to understand physical activity intentions and behavior among Korean breast cancer survivors.

The purpose of this study was to apply the theory of planned behavior (TPB) to understand physical activity intentions and behaviors among Korean breast cancer survivors. A total of 286 Korean breast cancer survivors (Mage52.3 ± 8.3) completed a self-reported survey administered face to face by a trained interviewer. The survey assessed the physical activity frequency and intensity in a typical week after breast cancer diagnosis, demographic factors, and theory of planned behavior variables including attitude, subjective norm, perceived behavioral control (PBC), planning, and intentions to participate in physical activity. We used structural equation modeling to examine the direct and indirect effects of the TPB variables on physical activity intentions and behavior. Covariates included age, cancer stage, and clinical treatment. Confirmatory factor analyses indicated a satisfactory model fit. We observed direct effects for instrumental attitude (ß = 0.34, p < 0.001), subjective norm (ß = 0.12, p < 0.05), and PBC (ß = 0.57, p < 0.001) on physical activity intentions. PBC (ß = .17, p < 0.01) and physical activity intentions (ß = 0.46, p < 0.01) had direct effects on planning. PBC (ß = 0.28, p < 0.01) and planning (ß = 0.22, p < 0.01) had direct effects on physical activity behavior. The TPB was a useful model for understanding Korean breast cancer survivors' physical activity intentions and behavior. Interventions that can enhance attitudes, subjective norm, PBC, intention, and planning may facilitate physical activity intentions and behaviors in this population.

Abstract As the rates of sexually transmitted infections among Brazilian youth rise, college students present with low rates of condom use. Understanding which factors affect preventive behaviours may assist in promoting them. This study aimed to test the Theory of Planned Behaviour (TPB) as a model of condom use behaviour among young university students. Data on sexual behaviour, TPB, and personality variables were collected online with 343 sexually active students aged between 18 and 29. Seventy participants also provided follow-up data after 30 days. Structural equation models and ordinal regressions were used to analyse the effects of TPB variables on condom use behaviour. Attitude was the main predictor of behavioural intention in the cross-sectional and longitudinal models. Being in a relationship and lower age at sexual debut were also associated with less frequent condom use behaviour in the cross-sectional analysis. Behavioural intention and perceived control were associated with condom use behaviour.

AN EMPIRICAL INVESTIGATION TO EXTEND THE THEORY OF PLANNED BEHAVIOR IN THE ORGANIC FOOD CONTEXT

The study aims to utilize the extended model of the theory of planned behavior (TPB), to test the impact on organic food consumption in Pakistan. Despite having an increased awareness about the benefits of organic food, the translation of favorable attitude and positive purchase intention into actual buying behavior remains quite low. A final sample of 778 was taken from Karachi through an online medium by using the purposive sampling technique. The data was analyzed by implementing the partial least squares structural equation modeling (PLS-SEM) technique through SmartPLS software. Findings of the study suggested that all the variables of TPB had a significant positive relationship, whereas the additional variables, including food safety concern, health consciousness, and environmental concern, also had a significant impact on consumers’ attitudes towards organic food. However, the moderating effect of trust between attitude-purchase intention as well as price consciousness between purchase intention-buying behavior relationship appeared to be insignificant. Thus, marketers can utilize the findings of the study to create appealing promotional messages by highlighting the benefits of organic food related to environmental sustainability, food safety as well as on consumers’ well-being. Further, government and policymakers can take actions to create awareness about the organic food consumption among locals to promulgate its usage in Pakistan. Keywords: Organic food, theory of planned behavior, trust, price consciousness.

The intention to get COVID-19 vaccine and vaccine uptake among cancer patients: An extension of the theory of planned behaviour (TPB).

The psychosocial impact of coronavirus disease 2019 (COVID-19) on human life is well-known. Although vaccine protection represents an effective way to control the spread of the virus, vaccination hesitancy may decrease individuals’ willingness to get vaccinated, including among cancer patients. Therefore, the objective of the current study was to examine the predictors of cancer patients’ intentions to receive COVID-19 vaccinations and vaccine uptake, using and integrating the theory of planned behaviour (TPB) and the health belief model (HBM). A sample of 276 Italian cancer patients (54% female and 46% male) ranging from 19 to 85 years (M = 49.64, SD = 11.53) was recruited by administering an online questionnaire. The current study results showed that cancer patients with higher trust in health authorities tended to have vaccine-positive subjective norms, perceived that vaccination was under their control, and viewed COVID-19 vaccines positively. On the other hand, the perceived risk of COVID-19 was related to subjective norms but not to perceived behavioural control or attitudes towards COVID-19 vaccination. The current study reveals that TPB variables can function effectively as mediators between perceived risk, trust, and intention to vaccinate but at different levels. Together, these findings suggest that effective interventions (both public health messaging and personal medical communications) should focus on enhancing trust in health authorities, while at the same time endeavouring to highlight subjective norms that are vaccine-positive.

How Does Personality Trait Affect Online Financial Service Use of College Students in China?

Online financial service is an essential part of consumption services provided by companies in modern society. It is vital to figure out the underlying mechanisms that influence online financial service use of college students in China, which is seldom explored. Drawing on the theory of planned behavior (TPB), this study explores the effect of personality traits (i.e., materialism) and its joint effect with attitude on online financial service use of college students. Moreover, we examined the interaction effects of key variables in TPB in the context of online financial services. The results indicated that the materialism value of Chinese college students has no direct effect on their intention to use online financial services but exerts an indirect effect through their attitude toward online financial services. College students' attitudes and perceived behavioral control are associated with their subjective norms, and in turn, affect their use intention of online financial services. In addition, perceived risk and perceived usefulness of online financial services also affect use intention through attitude and perceived behavioral control. The discussion of key findings, implications, and conclusions are provided.

A Rule-Generation Model for Class Imbalances to Detect Student Entrepreneurship Based on the Theory of Planned Behavior

Abstract The ability to identify the entrepreneurial potential of students enables higher education institutions to contribute to the economic and social development of a country. Current research trends regarding the detection of student entrepreneurial potential have the greatest challenge in the unequal ratio of datasets. This study proposes a rule-generation model in an imbalanced situation to classify student entrepreneurship based on the Theory of Planned Behavior (TPB). The result is a ruleset that is used for the early detection of student entrepreneurial potential. The proposed method consists of three main stages, namely preprocessing data to classify data based on TPB variables, generating a dataset by clustering and selecting attributes by sampling to balance the data, and finally generating a ruleset. Furthermore, the results of the detecting ruleset have been evaluated with actual data from the student tracer study as ground truth. The evaluation results show high accuracy so that the ruleset can be applied to the higher education environment in the future.

Prediction of urban cyclists’ intentions to ride on the pedestrian lane and against the traffic flow: A sociodemographic and psychosocial approach

Unsafe riding behaviors among urban cyclists compromise road safety and encourage a negative perception of cycling mobility. This study evaluates the influence of sociodemographic and psychosocial variables (attitude, subjective norm and perceived behavioral control) associated to the Theory of Planned Behavior (TPB) about cyclists’ intentions to ride on the pedestrian lane (RPL) and to ride against the traffic flow (RATF), to identify significant predictors. An online survey was applied among 200 urban cyclists (52 females and 148 males), in a mexican city with emerging cycling culture, in October 2020. A descriptive statistical analysis was conducted, and intention prediction models were built through hierarchical regression analyses. The three TPB variables were found to be the most significant predictors of the cyclists’ intentions towards RPL and RATF, above the sociodemographic variables considered. Perceived behavioral control was the strongest predictor. Findings, provide an empirical precedent in predictorś study on RPL and RATF in the context of emerging urban cycling environment. On the other hand, could guide road education policies focused on the found predictorś hierarchy. A variety of strategies could range from broad promotion of cycling mobility regulations and enforcement to awareness campaigns about the real adverse effects on safety and road coexistence, derived from RPL and RATF.

State defense internalization in a university: Theory of planned behavior approach

Universitas Pembangunan Nasional “Veteran” Jawa Timur (UPNVJT) is a university with state defense education’s characters. In practice, those character did not cover the academic field as a whole. Through the theory of planned behavior (TPB), the research carried out the process of internalizing state defense values in thesis writing as a form of character graduates. The research was conducted using a quantitative approach involving stakeholders at UPNJT, namely LP3M and head of department. Data were analyzed using partial least squares structural equation modeling (PLS-SEM) software. The results found that two TPB variables, namely attitudes and subjective norms in the organization, had an influence on the intention in implementing state defense values. The intention in implementing state defense values will influence perceived self-efficacy of state defense values. Meanwhile, the subjective norms of the perpetrators and the perception of behavioral control in accordance with the state defense values have no influence on the intention in implementing the state defense values.

Antecedents of public participation intention in waste incineration power projects: an empirical study from China

To fully investigate the antecedents of public participation intention, a holistic framework was developed by integrating theory of planned behavior (TPB) and norm activation model (NAM), coupling with corporate social responsibility (CSR), community organizational support (COS), and channel availability (CA). Data was collected from questionnaire surveys conducted with nearby residents of three waste incineration power (WIP) projects in China, and was analyzed using structural equation modeling. The results indicated that all variables of TPB and NAM, except perceived behavioral control, were validated to positively affect participation intention. Moreover, CSR was found to have a positive effect on participation intention, while CA played a negative role. The positive moderating effect of COS on the relationship between CSR and participation intention was also supported. By comprehending the factors motivating participation in WIP projects, the findings contribute to developing participation intervention policies and addressing Not-In-My-Back-Yard issues of the projects referring to environmental hazard.

Examining consumer's purchasing behavior of energy-efficient appliance through the lenses of theory of planned behavior and environmental factors

PurposeThis study investigates consumer purchases of energy-efficient appliances (EEAs). The adoption of EEA would reduce the detrimental impact of the environment from the consumer behavioral perspective.Design/methodology/approachThis study evaluates consumer purchase of EEA based on the theory of planned behavior (TPB), environmental factors, and consumer energy-efficient behavior (EEB). Applying partial least square structural equation modeling (PLS-SEM), 412 household respondents within the five regions in Malaysia were analyzed.FindingsFindings depicted that EEB has a significant influence on intention to purchase and subsequently purchasing behavior of EEA. Similarly, the TPB variables were significant predictors of EEB and intention to purchase except for attitude. Meanwhile, among the environmental factors, only environmental awareness was significant.Research limitations/implicationsImplications include integrating educational programs through formal and informal measures. The former includes infusing within the mainstream educational system. On the other hand, the latter is through effective and captivating media communication.Originality/valueThe integration of EEB towards consumers' intention and behavior of purchasing EEAs.

Behavior Model Analysis of Pedestrians and Cyclists Mode Selection Base on Active Transportation on Universitas Jember Tegalboto Campus

Abstract The University of Jember as one of the campuses that have a high traffic volume is trying to realize a “Green Campus” through the “Ring the Bell” program. However, this vision has not been implemented optimally because there are still many campus residents who do not use active modes of transportation (walking &amp; cycling) even though sidewalk facilities are available. This indicates that the behavioral preferences for choosing active transportation modes for the residents of the Jember University campus are still unclear. Therefore, this study aims to analyze the behavioral model of pedestrian and cyclists mode selection based on active transportation at the Tegalboto Campus, Jember University. The primary data collection of residents’ preferences was obtained through the TPB (Theory Of Planned Behavior) questionnaire. SEM model (Structural Equation Model) was applied in the behavioral analysis process to determine the interaction between the independent variables of TPB as a whole. The results of behavioral modeling show that intention is the variable that most influences the behavior of campus residents in using active transportation modes, while attitude is the variable that most influences intentions than subjective norms and perceptions of behavioral control.

Improving Sleep Among Teachers: an Implementation-Intention Intervention

BackgroundInsufficient sleep is common among teachers and is associated with diverse health risks. This study aimed to predict intention and sleep duration by applying the Theory of Planned Behavior (TPB) and to examine the effectiveness of an implementation-intention intervention to improve sleep duration and quality.MethodSixty-nine teachers (M = 36.8 years, SD = 10.4) were assigned to an active control group (CG) or intervention group (IG). At baseline, TPB variables were assessed and participants of the IG received instructions to develop implementation intentions to reach the goal of sleeping 8 h on average. During a 3-week intervention period, all participants wore an activity tracker (Fitbit Charge HR) to measure sleep duration and kept diaries to assess sleep quality, physical activity, and stress. After 1 month, a 1-week follow-up, including a booster for the IG, was conducted.ResultsForty-two percent of variance in sleep duration were explained by control variables, past behavior, perceived behavioral control, and intention. Mixed ANOVAS with baseline covariates found a large main effect with longer sleep duration in the IG. A time x group interaction suggested that only the IG slept significantly longer in the follow-up period compared to the intervention period. For sleep quality, a medium-sized main effect for study group was found and a time x group interaction indicated higher sleep quality in the IG for week 3 and the follow-up.ConclusionThe TPB was effective in predicting sleep intention and duration. Implementation intentions accompanied by daily monitoring and a booster appear to be promising for improving sleep.

Comparing the Relative Importance of Predictors of Intention to Use Bicycles.

The use of bicycles for active commuting is an important target to reach because of the importance of increasing physical activity among the population and improving the air quality in cities. Among the models that have been utilized in previous studies, the Theory of Planned Behavior (TPB) has shown good results in terms of the total variance obtained. However, establishing the relative importance of the TPB variables is difficult. In the present study, which was carried out in the Italian context, the authors sought to establish the weight of the proposed variables based on the dominance analysis approach. Considering the initiatives, which the Italian government carries out, and the particular period in which the study was developed, the authors included two variables in addition to the classical factors: financial incentives and daily commuting habits. A survey was administered to 294 Italians (222 females and 72 males, from 18 to 77 years old) through social networks from July to September 2020. The results have shown how the main predictor of bicycle use was use habits, followed almost at the same level by financial incentives and attitude, while norms and perceived behavioral control (PBC) present low relative importance among the variables considered. Limits of the study have been discussed, and suggestions for future research have been proposed.

Determining intention, fast food consumption and their related factors among university students by using a behavior change theory

BackgroundToday, with the advancement of science, technology and industry, people’s lifestyles such as the pattern of people’s food, have changed from traditional foods to fast foods. The aim of this survey was to examine and identify factors influencing intent to use fast foods and behavior of fast food intake among students based on the theory of planned behavior (TPB).MethodsA cross-sectional study was conducted among 229 university students. The study sample was selected and entered to the study using stratified random sampling method. Data were collected using a four-part questionnaire including Participants’ characteristics, knowledge, the TPB variables, and fast food consumption behavior. The study data were analyzed in SPSS software (version 16.0) using descriptive statistics (frequencies, Means, and Standard Deviation) and inferential statistics (t-test, Chi-square, correlation coefficient and multiple regressions).ResultsThe monthly frequency of fast food consumption among students was reported 2.7 times. The TPB explained 35, 23% variance of intent to use fast food and behavior of fast food intake, respectively. Among the TPB variables, knowledge (r = .340, p < 0.001) and subjective norm (r = .318, p < 0.001) were known as important predictors of intention to consume fast foods - In addition, based on regression analyses, intention (r = .215, p < 0.05), perceived behavioral control (r = .205, p < 0.05), and knowledge (r = .127, p < 0.05) were related to fast food consumption, and these relationships were statistically significant.ConclusionsThe current study showed that the TPB is a good theory in predicting intent to use fast food and the actual behavior. It is supposed that health educators use from the present study results in designing appropriate interventions to improve nutritional status of students.

Employing the theory of planned behaviour to design an e-cigarette education resource for use in secondary schools

BackgroundAn extended version of the theory of planned behaviour (TPB) was used to inform the design of a framework for an educational resource around e-cigarette use in young people.MethodsA sequential exploratory design was employed. In Phase 1, elicited behavioural, normative and control beliefs, via 7 focus groups with 51 participants, aged 11–16 years, identified salient beliefs around e-cigarette use. These were used to construct a questionnaire administered to 1511 young people aged 11–16 years, which determined predictors of e-cigarette use and ever use. In Phase 2, sociodemographic variables, e-cigarette knowledge, access, use, marketing and purchasing of e-cigarettes and smoking behaviour were also gathered. The composite findings from Phase 1 and 2 informed the design of a post primary educational resource in Phase 3 around e-cigarette use.ResultsCurrent e-cigarette use was 4%, with almost 23% reporting ever use, suggesting current use is stable but experimentation may be increasing in this cohort. Sociodemographic variables, knowledge of e-cigarettes, smoking behaviour and TPB variables (direct and indirect measures of attitudes, subjective norm, and perceived behavioural control) accounted for 17% of the variance in current e-cigarette use, with higher intentions to use e-cigarettes within the next month, having the strongest impact on use (p < 0.001), followed by self-efficacy (p = 0.016). Sociodemographic and TPB variables accounted for 65% of the variance in intentions to use e-cigarettes in the next month; current e-cigarette use (p < 0.001), more positive attitudes (p < 0.001), stronger social influence (p < 0.001), higher self-efficacy (p < 0.001), higher control beliefs (p < 0.001) and greater motivation to use e-cigarettes (p < 0.001) were the main predictors of intentions. Phases 1 and 2 informed the mapping of key predictors of intentions and use of e-cigarettes onto the Theoretical Domains Framework, which identified appropriate intervention functions and behaviour change techniques.ConclusionsThis paper is the first to bridge the theoretical-practice gap in an area of significant public health importance through the development of a framework for a novel theory driven school-based educational resource aimed at reducing experimentation and uptake of e-cigarette use in young people.

Extracting Travelers’ Preferences toward Electric Vehicles Using the Theory of Planned Behavior in Lahore, Pakistan

The high use of gasoline and diesel vehicles results in environmental pollution and loss of natural resources. The use of electric vehicles can be socially beneficial and reduce air pollution. In this research study, the main aims are to identify the potential of Electric Vehicles (EVs) in Pakistan using a Stated Preferences (SP) survey. An SP questionnaire was designed using the theoretical framework of the Theory of Planned Behavior (TPB). This questionnaire consisted of travelers’ personal and travel characteristics and various statements designed to address the variables of TPB such as Attitudes Towards the Electric Vehicles, Subjective Norms (SN), Perceived Behavioral Control (PBC), and Behavioral Intentions (BI). The behavior items were designed in the context of travelers’ willingness to buy and use EVs. Confirmatory Factor Analyses (CFAs) were conducted to validate the designed hypotheses related to the variables of TPB. The cross-analysis revealed that there are variations in responses across different occupations, trip distances, travel modes, and vehicle ownership. The developed structural models showed that the Attitudes and PBC have a positive influence on BI and PBC, which also have a direct impact on travelers’ willingness to use EV. The SN, PBC, and Attitudes are significant predictors of behavioral intentions in the willingness to buy EV and PBC is not a direct predictor of travelers’ willingness to buy an EV. The BI acts as a mediator to explain the indirect effects of Attitudes, SN, and PBC on willingness to purchase and use an EV. In the end, a framework is also proposed for the behavior-related interventions to promote the EVs considering the socio-economic context of Pakistan.

The Effect of Social Norms on Physicians' Intentions to Use Liver Cancer Screening: A Cross-Sectional Study Using Extended Theory of Planned Behavior.

BackgroundLiver cancer is a globally acknowledged threat to public health, and there is a critical and urgent need to determine factors associated with the use of liver cancer screening and to further promote its use.PurposeTo examine whether the extended theory of planned behavior (TPB) incorporating social norms predicts physicians’ intentions to use liver cancer screening and to identify the associated factors quantitatively, using contrast-enhanced ultrasound (CEUS) as an example.MethodsA research framework was established by adding social norms to the TPB, based on which the questionnaire for this study was developed. Through multistage random sampling, a cross-sectional questionnaire survey was conducted among 292 physicians in Fujian and Jiangxi provinces. Due to the multicollinearity problem of the data, ridge regression was applied to determine the influencing factors of physicians’ intentions to use CEUS.ResultsMost participants (87.30%) reported that they were willing to use liver cancer screening in their clinical practice. The scores of TPB variables were generally higher than those of social norms variables. Ridge regression results indicated that the proposed model was explanatory, which has accounted for 73.5% of the total variance in physicians’ intentions. Analyses also illustrated the significant role of TPB variables (attitude and perceived behavioral control) and social norms variables (personal norms, organizational norms, and industrial norms) on physicians’ intentions to use CEUS.ConclusionThe study extended the TPB by including the concepts of social norms, which is not only conducive to expanding the knowledge of factors associated with physicians’ intentions to use liver cancer screening, but also provides implications for developing strategies to promote the use of certain health services or products, such as playing the role of core members, holding panel meetings, and establishing information push systems.

Tracking the Path of the Green Consumer: Surveying the Decision-Making Process from Self-Transcendent Values to Supportive CSR Intentions

This paper examines the relationship between individual traits and values of consumers and their decision-making process pertaining to purchasing green products from companies with a strong commitment to corporate social responsibility (CSR). Guided by the theory of planned behavior (TPB), the main goal of this online survey (N = 463) is to understand the relationship between self-transcendent values, environmentalism, attitudes, norms, perceived behavioral control, intentions, and purchase frequency to better understand how consumers make green purchasing decisions. A structural equation model shows support for our predictions that self-transcendent values significantly and positively predict environmentalism, which in turn predicted the TPB variables. Interestingly, only attitudes towards purchasing green products were significantly predictive of purchasing products from companies with strong commitments to CSR, which subsequently predicted actual purchase frequency. We hope that our research will benefit scholars and practitioners by contributing to the work in CSR and environmental communication.

Predicting Intention to Take a COVID-19 Vaccine in the United States: Application and Extension of Theory of Planned Behavior

PurposeThis study aims to apply and extend the theory of planned behavior (TPB) to predict intention to take a COVID-19 vaccine.DesignCross-sectional.SettingOnline.SampleAdult US residents recruited from Amazon Mechanical Turk (n = 172).MeasuresIntention to take a COVID-19 vaccine (outcome variable), demographic variables (predictors), standard TPB variables (perceived behavioral control, attitude, and subjective norm; predictors), and non-TPB variables (anticipated regret, health locus of control, and perceived community benefit; predictors).AnalysisHierarchical linear regression predicting intention to take a COVID-19 vaccine, with demographic, standard TPB, and non-TPB variables entered in regression models 1, 2, and 3, respectively.ResultsThe extended TPB model accounted for 72.5% of the variance in vaccination intention (p < .001), with perceived behavioral control (β = .29, p < .001), attitude (β = .23, p = .043), and perceived community benefit (β = .23, p = .020) being significant unique predictors.ConclusionDespite the relatively small and non-representative sample, this study, conducted after COVID-19 vaccines were widely available in the USA, demonstrated that perceived behavioral control was the most robust predictor of intention to take a COVID-19 vaccine, suggesting that the TPB is a useful theoretical framework that can inform effective strategies to promote vaccine acceptance.

Pro-environmental purchase intention towards eco-friendly apparel: Augmenting the theory of planned behavior with perceived consumer effectiveness and environmental concern

ABSTRACT The textile industry has emerged as a major pollution source owing to a rise in carbon footprint, the spike in greenhouse gas emission, and increasing landfill waste. Sustainable fashion has become a new style statement and industries are shifting their orientation towards environment-friendly manufacturing. The theory of planned behavior (TPB) model was employed with environmental concern, personal moral norms, and perceived consumer effectiveness to better predict the eco-friendly apparel purchase intention of educated Indian youths. Variance-based partial least square-structural equation modeling (PLS-SEM) was applied to evaluate the hypothesized model. Findings indicated that perceived behavioral control has a strong significant positive influence on purchase intention followed by personal moral norms, attitude, and perceived consumer effectiveness. Environmental concern was found to have an indirect effect on purchase intention through three primary TPB variables and personal moral norms. Multi-group analysis (MGA) was performed to examine the moderating effect of perceived consumer effectiveness on an attitude–intention relationship. The highly perceived consumer effectiveness group was shown to have a more consistent attitude-purchase intention relationship as compared to the low-perceived consumer effectiveness group. The study promulgates insights to professionals and policymakers to formulate sustainable marketing strategies and policies to cope with the indigenous market conditions.
