This paper focuses on plastic waste sorting intentions to address municipal solid waste challenges in developing countries. This study also adapts the theory of planned behavior (TPB) in evaluating the determinants of plastic waste sorting intentions among Nigerian students. Nine hundred and thirty-nine respondents participated through questionnaire surveys. Findings of structural equation modelling depict that perceived behavioral control had the highest impact on the respondents’ plastic waste sorting intentions, followed by subjective norms; however, attitude was found to be insignificant and TPB explained 77% of the variance in waste sorting intentions. The importance of other influencing factors is also considered such as environmental awareness, volunteering, and study program in evaluating plastic waste sorting intentions and these factors were found to be statistically significant. Therefore, the results from this study add to the limited body of information on the application of TPB and other influencing factors in the study of plastic waste sorting in Nigeria. The findings also provide suggestions to current and prospective policymakers on the relevance of introducing waste sorting management practices such as recycling bins in Nigerian university premises and campaigns for waste sorting and recycling activities.

AbstractTo research the influencing factors of college students' blood donation behavior intention and propose intervention strategies to improve the repeated blood donation rate of college students. Questionnaire survey was used to research and analyze the influencing factors of behavior intention. Amos 21.0 software was used to establish structural equation modeling and perform confirmatory factor analysis. SPSS 20.0 was used for statistic. The model was proved with highly adaptability, with χ2/df = 2.956 < 3. Factors influencing college students' intention of repeat blood donation behavior can be summarized into four: attitude, external motivation, advice-taking, and perceived behavioral control. Among them, attitude and perceived behavioral control have a great direct impact on behavioral intention, while the external motivation and recommendation acceptance have an indirect impact by influencing the other two factors. In view of those evaluation items with high path coefficient in each factor, we can develop recruitment strategies to influence college students’ repeated blood donation behavior and provide scientific suggestions for improving their repeated blood donation rate.

<p>The study examined factors affecting Behavioral Intention (BI) regarding students’ choice of educational administration as their major. Samples were taken from Indonesian students. The process was begun with the adaptation of survey instruments from previous studies validated through content validity. In testing the normality, Skewness and Kurtosis values were computed. Reliability assessment was applied through Cronbach’s alpha. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were both conducted for the constructs. In examining the relationship, Structural Equation Modeling (SEM) analysis using AMOS 23.0 was applied to 257 responses. The findings informed that two relationships were significant while the other two are insignificant. Perceived Behavioral Control (PBC) and Attitude (AT) significantly predicted BI, while Subjective Norm (SN) and Facilitating Condition (FC) did not significantly predict BI. The current study can expand an in-depth contribution and reference for further researchers as a basis of the empirical evidence in relation to the validated survey questionnaire. Access to the questionnaire may contribute to educational stakeholders establishing policies to improve students’ interests in studying in an educational administration study program.</p>

Green residence is the future of urban development, it is also an attempt to implement the green business model in the residential business field. The key to the success of a green business model is that a wide range of customers can accept its green value proposition and react to it through their purchase decisions. This study aims to develop a theory of a planned behavior (TPB) research model to predict individuals’ intention to purchase green residence. This study took steel structure residence as an example, which was widely recognized as one emerging type of green residence. The samples were selected in Baotou city of Inner Mongolia, P.R. China. Data analysis was performed using the structural equation modeling (SEM) with data obtained from a survey of 208 respondents using SPSS19.0 and AMOS17.0. The results found that the individuals’ intention to purchase green residence was significantly affected by attitude, subjective norm, and perceived behavioral control. Moreover, the empirical evidence showed that these influences differed between different gender groups. Specifically, women responders had a stronger effect on the path attitude impact on purchase intention than men. These findings can provide implications for practicing the green business model of real estate enterprise.

AbstractGrounded in Interpersonal Acceptance-Rejection Theory (IPARTheory), this exploratory study investigated the associations among perceived intimate partner rejection, intimate partner control, psychological maladjustment, and marital adjustment. Perceived behavioral control in intimate partner relationships has been under-researched within the context of IPARTheory. Although the role of behavioral control in child/adolescent-parent relationships has been well-established, insufficient exploration of the phenomenon in marriage relationships calls for new empirical findings. The conveniently selected sample consisted of 624 (360 female, 264 male) married individuals living in big cities of Turkey. Intimate Partner Acceptance-Rejection/Control Questionnaire, Personality Assessment Questionnaire, Dyadic Adjustment Scale, and Demographic Form were utilized to gather data. Structural Equation Modeling was utilized as the primary analysis to test the proposed sequential mediational model of the study. The results indicated that intimate partner behavioral control was significantly and indirectly associated with marital adjustment through the mediating effects of intimate partner rejection and psychological maladjustment. Moreover, intimate partner rejection had direct effects on psychological maladjustment and marital adjustment. The indirect effect of intimate partner rejection on marital adjustment via the mediation of psychological maladjustment was found to be significant. Lastly, the sequential mediation by intimate partner rejection and psychological maladjustment in the relationship between intimate partner control and marital adjustment was also significant. This study adds to the existing literature on IPARTheory by showing that perceived intimate partner behavioral control is quite negatively related to marital adjustment. Results underscore how perceived behavioral control by a spouse triggers rejection and diminishes the psychological adjustment of the controlled partner.

Abstract Introduction The physicians are responsible for prescribing medicine rationally. Physician's awareness of prescribing guidelines can lead to the selection of the most effective, appropriate and effective measures to the improved prescription. This study aim is to determine the factors influencing drug prescribing behaviour in family physicians. Methods This cross-sectional study was conducted in 2016 on a case study including 150 family physicians from Shiraz City who were selected by systematic random sampling method. A questionnaire related to the behaviour of prescribing physicians was used based on the theory of planned behaviour to collect data. The validity of the questionnaire was confirmed by the experts' opinion and its reliability was confirmed by calculating the Cronbach's alpha. The data were analyzed using structural equation modelling (SEM) by SPSS and Smart PLS software. Results It was specified that 39.3% of Shiraz family physicians have prescribed medicines for their most patients (61-70%) during the last month. Furthermore, 60% of physicians have prescribed for about 20% of their patients without any examination. In addition, 63% of doctors have repeated prescription for about 20% of patients with chronic disease. Based on the obtained results of the Research Structural Equation Model, none of the four considered variables explains changes in physicians' behaviour regarding prescribing. Although, “mental and perceived behavioural control” explain 30.2% of the changes in the intention of prescribing medication of family physicians in Shiraz. Conclusions The family physicians' behaviour in prescribing medicine shows the impact of factors such as the patient's request, as well as the role of the patients and colleagues pressure for prescribing medicine as a quality criterion for their practice. norms of mental and perceived behavioural control are effective in explaining the purpose of prescribing. Key messages Policymakers should implement policies to develop physicians’ behavior and logical prescription by education, financial incentives; consequently. Mental and perceived behavioral control are effective in explaining the purpose of prescribing.

Whistleblowing is a psychological process that involves the calculation of risks and benefits. While there exists a broad range of research on whistleblowing in the public sector, previous studies have not examined its entire process due to the limited focus on either whistleblowing intention or whistleblowing behavior. This study aims to fill this gap by applying the theory of planned behavior (TPB) to the whistleblowing context. Specifically, we examine how individual beliefs about the likely consequences of whistleblowing (attitude toward whistleblowing), others’ expectations about whistleblowing (subjective norm), and the capability of blowing the whistle (perceived behavioral control) influence public employees’ actual whistleblowing by way of their intention to report wrongdoings. A series of structural equation models are tested using data from the 2010 Merit Principles Survey. The findings show that the more the employees perceive that the consequences of whistleblowing are important, the more the key referents support whistleblowing, and the more the protections for whistleblowers are available, the more likely are their intentions to disclose wrongdoings and then actually engage in whistleblowing behavior. We conduct additional analyses for internal and external whistleblowers separately and find that there are both meaningful similarities and differences between the two groups. This study provides support for the validity of TPB as a theoretical framework for better understanding and explicating the psychological process of bureaucratic whistleblowing.

The purpose of this study is to apply the conceptual framework of the theory of planned behavior (TPB) to explain the consumption of sustainable produced fish in Sweden. We seek to understand the moderating role of food product involvement and environmental awareness as extensions of traditional constructs such as attitudes, social norms, and perceived behavioral control. The data were derived from a representative sample of 1974 Swedish consumers. Structural equation modeling was applied to test the relationships between constructs and evaluate the reliability and the validity of the constructs. Attitudes had a significantly positive effect on intention to consume fish in general and sustainably produced fish in particular. Social norms had significantly positive effect on intention to consume fish in general, but no effect on intention to consume sustainably produced fish. Behavioral control had no effect on behavioral intention. Interestingly, involvement negatively moderated the effect of attitudes on both intention to consume more fish and to consume more sustainably produced fish. Environmental awareness also negatively moderated the effect of attitudes on intention to consume more sustainably produced fish. It seems that attempts to create food product involvement and environmental awareness among consumers may have the opposite effect—a boomerang effect—than what conventional wisdom and much of the research on fish consumption indicates. Theoretical and practical implications of the findings are discussed.

Introduction: There is no universal scale for assessing waterpipe tobacco (WT) dependence. We examined the factorial structure and psychometric properties of the Waterpipe Dependence Scale-11 (LWDS-11) among Egyptian WT smokers. Methods: We administered the LWDS-11 during face-interview questionnaires in two cross-sectional surveys among 1490 current WT smokers recruited via purposive quota sampling. Exploratory factor analysis was performed on half of the sample. Confirmatory factor analysis of the resulting model was done using structural equation modelling on the other half. Scale reliability was examined. We assessed convergent construct validity using regression models to examine the association between the adapted dependence scale and factors conceptually expected to be associated with WT dependence. Results: Exploratory factor analysis of the scale yielded eight items (E8-LWDS) supporting a three-factor structure: physical dependence (three items); psychological dependence (three items); and psychological craving (two items). Cronbach’s α were 0.635 for the total scale and 0.823, 0.654, and 0.785 for the three subscales. E8-LWDS was confirmed to have good model fit (comparative fit index = 0.995; root mean squared error of approximation = 0.027). E8-LWDS was independently associated with daily WT smoking, rural residence, being a skilled worker, non-exclusive WTS, smoking ≥ eight WT hagars/day, and measures of perceived behavioral control (self-reported addiction to WT, perceived ability to quit, and previous quit attempts). Conclusion: E8-LWDS showed adequate psychometric properties among this sample of Egyptian current WT smokers, which makes it appropriate for use by researchers and practitioners. Adding items related to perceived behavioral control might enhance the scale robustness.

Innovations in food packaging, such as active and intelligent ones, improve food safety and lower household food waste by extending product shelf life and providing information about food quality, respectively. The consumer adoption of such innovations could contribute to reaching one of the Sustainable Development Goals which calls for halving the per capita global food waste by 2030. Thus, this paper aims to investigate the consumers’ willingness to purchase active and intelligent packaging to reduce household food waste using a sample of 260 Italian consumers and a modified Theory of Planned Behavior (TPB) model. Using a structural equation model, findings show that respondents are more willing to purchase intelligent packaging rather than active packaging to reduce their wastes at home. Finally, attitudes, perceived behavioral control, awareness, and planning routines are the most important drivers of the intention to reduce household food waste.
