This study aimed at assessing the impacts of the fear of COVID-19 on consumer buying behavior toward dietary supplements. This investigation was a cross-sectional study in which literate adults regardless of gender over the age of 20 were recruited from three pharmacies in three different districts of Wuhan City, China. A total of 598 questionnaires were analyzed after excluding 10 with incomplete information. The current study demonstrated that attitudes, subjective norms, and perceived behavioral control had a positive impact on the intention of purchasing dietary supplements. Fear of COVID-19 was related to an enhanced purchase intention toward dietary supplements. Attitudes, subjective norms, and perceived behavioral control were significant factors that mediated the association between the fear of COVID-19 and the purchase intention of dietary supplements. This study helps provide practical advice for stakeholders in the pharmaceutical and healthcare industries to tailor appropriate strategies for improving product promotion or healthcare-related interventions.

College students are heavy consumers of energy beverages, yet further study is needed to better understand determinants of use. The purpose of this cross-sectional study ( N = 283) was to identify beliefs explaining unsafe consumption practices. A principal components analysis revealed three eigenvalues >1 explaining approximately 55% of the variance (health and appearance, performance and fatigue, and recreation and alcohol). Multiple regression analysis explained 75% of the variance for intent to consume. Standardized beta for attitude and subjective norms was p < .001; perceived behavioral control was p < .05. MANOVA was used to determine the effect of gender on eight dependent variables (Wilks’s lambda = 3.78, p < .001). Attitudes and subjective norms influenced the intent to consume energy beverages, particularly in males. Students viewed energy beverages as useful for managing health and appearance and performance and fatigue, and as a way to enhance recreation and alcohol consumption.

Background: Plagiarism is one of the most common and important misconducts in the educational and research environment. Plagiarism means transcribing the works or ideas of others without authenticating the source and the original author and assigning them to self. Objectives: The current research aimed to investigate the socio-cognitive constructs associated with plagiarism among Kermanshah University of Medical Sciences (KUMS) students using the theory of planned behavior (TPB). Methods: This cross-sectional study was done at KUMS, the west of Iran, among 231 medical university students in 2018, which were selected randomly to participate voluntarily. Students filled out a self-report questionnaire that included the demographics and TPB variables. Data gathered were analyzed by the Statistical Package for Social Sciences (version 16) using a t-test, Pearson correlation, and linear regression. Results: The determinants of attitude, subjective norms (SN), and perceived behavioral control (PBC) accounted for 15% of behavioral intention (BI) to plagiarism. Linear regression showed that SN (beta = 0.229; P = 0.001) and PBC (beta = -0.217; P = 0.001) were the most influential predictors of plagiarism intention. Conclusions: According to the result, it seems that planning programs to increase perceived behavioral control against doing plagiarism and reduce subjective norms encouraging plagiarism may be useful for the prevention and reduction of plagiarism among university students.

In response to global calls for environmental awareness, the Malaysian government enforced restrictions on plastic usage in the Malaysian foodservice industry in 2020. Despite the efforts of public awareness campaigns championing the detrimental effects of traditional plastic usage, the impact of measures taken by food traders remains inadequate. The paper seeks to explore the relationship between subjective norms, perceived behavioral control, attitude, and the intention to use biodegradable straws among food traders. Purposive sampling method, the Structural Equation Model (SEM), and Partial Least Squares (PLS) tools were employed. The sample included 270 respondents. The result found a significant correlation between the four variables, i.e., subjective norms, perceived behavioral control, attitude, and intention to use. Hence, results obtained indicate that conscientious consumers have a significant influence on businesses in their quest to reduce their overall impact on the surrounding environment. Consequently, their socially responsible decisions, i.e., initiatives of using biodegradable products, have advocated mindful consumerism and encouraged positive purchasing behaviors. The results predict increasing demands as an outcome of this accumulated synergy, and this in turn provides more opportunities for food traders and their associated counterparts. The contributions of this study extend toward both theoretical and practical knowledge: (a) better understanding of consumer attitude and how it influences purchase intention, and (b) government regulation and enforcement towards environmental awareness and activities associated with global contributions.

ABSTRACT Objective: women are more likely to give birth at a health facility when their families agree with the birthplace. However, in rural areas of Tanzania, women are often marginalized from decision-making. This study predicted birthplace intention and identified factors to reduce perceptional gaps among pregnant women, husbands and family members. Method: explanatory cross-sectional survey was conducted in three villages in North Eastern Tanzania. Participants were 138 pregnant women and their families who answered the Birth Intention Questionnaire (BIQ), measuring knowledge, attitude, perceived behavioral control, subjective norms and intention for birthplace. Descriptive analysis, ANOVA, Chi-square, and multiple linear regression was used to analyze the data. Results: the regression model showed that knowledge, perceived behavioral control, and subjective norms predicted intention for birthplace (R2 = .28). While 81% of pregnant women thought their husbands were decision-makers for their birth, only 38% of husbands and 37% of family members agreed. Pregnant women had significantly lower scores on the item “I will prepare for childbirth with my family” compared with husbands (p < .01) and other family members (p < .001). Conclusion: providing evidence-based birth preparation and reducing the identified perceptual gaps may enhance women’s intention to deliver at health facilities.

I conducted a survey to examine the impact of subjective norms, behavioral attitude, and perceived behavioral control on ethical purchase intention with 445 consumers selected by random sampling in Wuhan City, China. Results based on a structural equation model showed that behavioral attitude, subjective norms, and perceived behavioral control all significantly influenced ethical purchase intention of the respondents, with subjective norms being the strongest predictor of ethical purchase intention. Furthermore, perceived behavioral control not only significantly and directly influenced ethical purchase intention but also had an indirect influence on ethical purchase intention through behavioral attitude as a mediator.

Abstract Background Cervical cancer is the second most common cancer and the fifth deadliest cancer among women in Iran. Educational interventions based on the proper behavior promoting models can lead to early diagnosis of cervical cancer.This study aimed to investigate the effects of educational intervention on performing Pap smear tests based on the Theory of Planned Behavior among women living in Fasa, Iran. Methods A cross-sectional study was conducted on 700 participants. Thereafter, the educational intervention based on the results of cross-sectional study was conducted in a workshop form for 50 women as the intervention group and 50 women as the control group. Afterward, the data were entered into the SPSS statistical software and then analyzed via logistic regressions analysis, paired t test, independent t test, chi-square test, and McNemar test. Result According to the results, 45.7% of the patients had a history of performing a Pap smear test, and 20.7% of them regularly performed this test. The knowledge, attitude, subjective norms, and perceived behavioral control were the predictors of intention and behavior of Pap smear test among the women (P < 0.05). These components accounted for 57.4% and 31.6% of the intention and behavior variances, respectively. After the intervention, a significant increase was observed in the means of attitude, subjective norms, and perceived behavioral control in the intervention group compared to the control group. The results reveal no significant difference between these two groups regarding the behavioral intention (p = 0.41) and performance of the Pap smear test (p = 0.583). The number of the participants undergone the Pap smear test has increased from 10 to 26 in the intervention group by passing 3 months from the intervention. The results of McNemar test indicated that this difference was statistically significant. Conclusion The results indicated an increase in the women’s performance of the Pap smear screening test by appropriate planning, provision of educational packages based on the women’s needs, and using effective subjective norms.

This study examines some antecedents of the intention and behavior toward buying counterfeit luxury goods among young consumers in Vietnam, an Asian emerging economy. The data was obtained from university undergraduate students in Hanoi, the capital of Vietnam. The results of structural equation modeling show support for most of our hypotheses. The findings indicate that materialism (the centrality component) has positive impact on attitude toward purchase of counterfeit luxury goods. Attitude and subjective norm toward counterfeit luxury goods are found to be positively related to purchase intention, while perceived behavioral control is not found to have a direct impact on purchase intention. In addition, perceived behavioral control and purchase intention are found to be significant predictors of purchase behavior. The research findings are discussed and implications for managers and policy makers are provided.

Abstract Background The present study aimed to develop and test an extended theory of planned behavior (TPB), which includes attitudes, subjective norms and perceived behavioral control, oral health knowledge, and past oral health behavior on the intention to improve oral health behaviors among primary school students in Shanghai, China. Methods A school-based cross-sectional study was conducted with 414 students in the third-grade from 10 classes of Mingqiang Primary School located in Shanghai, China. Participants were recruited in October 2019. Data were collected through self-reported questionnaires, consisting of demographic characteristics, TPB variables, oral health knowledge and past oral health behaviors. Exploratory factor analysis was used to analyze TPB items. Pearson’s correlation and hierarchical regression analyses were conducted to identify the associated factors of intention to improve oral health behaviors. Results The study showed that among students in the third grade, attitudes, subjective norms, perceived behavioral control, and past oral health behaviors were associated with the intention to improve oral health behaviors. In the hierarchical regression analysis, age and sex were entered in Model 1 which significantly explained 3.00% of the variance (F = 6.26, p < 0.01). The addition of Model 2 variables of attitudes, perceived behavioral control, subjective norms, and oral health knowledge revealed that TPB variables explained 26.70% (F = 29.59, p < 0.01). For Model 3, the addition of past oral health behaviors accounted for a further 1% of variance, and the full model has accounted for 28.30% of the variance with the intention to improve oral health behaviors (F = 22.8, p < 0.01). Regression analyses supported that among the significant variables, perceived behavioral control had the largest beta weight, followed by subjective norms and past oral health behaviors. Conclusion The extended TPB model constructed in this study could be used to explain children’s intentions to improve oral health behaviors. Children’s oral health-related perceived behavioral control, subjective norms, and past oral health behaviors may serve as priority intervention targets in oral health promotion practices aimed at children.

Abstract. Background: Worldwide prevalence of peripheral artery disease (PAD) is increasing and peripheral vascular intervention (PVI) has become the primary invasive treatment. There is evidence that multidisciplinary team decision-making (MTD) has an impact on in-hospital outcomes. This study aims to depict practice patterns and time changes regarding MTD of different medical specialties. Methods: This is a retrospective cross-sectional study design. 20,748 invasive, percutaneous PVI of PAD conducted in the metropolitan area of Hamburg (Germany) were consecutively collected between January 2004 and December 2014. Results: MTD prior to PVI was associated with lower odds of early unsuccessful termination of the procedures (Odds Ratio 0.662, p < 0.001). The proportion of MTD decreased over the study period (30.9 % until 2009 vs. 16.6 % from 2010, p < 0.001) while rates of critical limb-threatening ischemia (34.5 % vs. 42.1 %), patients´ age (70 vs. 72 years), PVI below-the-knee (BTK) (13.2 % vs. 22.4 %), and rates of severe TASC C/D lesions BTK (43.2 % vs. 54.2 %) increased (all p < 0.001). Utilization of MTD was different between medical specialties with lowest frequency in procedures performed by internists when compared to other medical specialties (7.1 % vs. 25.7 %, p < 0.001). Conclusions: MTD prior to PVI is associated with technical success of the procedure. Nonetheless, rates of MTD prior to PVI are decreasing during the study period. Future studies should address the impact of multidisciplinary vascular teams on long-term outcomes.

This study focuses on examining the impact of three components of materialism on green purchase intention for urban consumers in Vietnam, an emerging economy. An extended Theory of Planned Behavior (TPB) is applied as the conceptual framework for this study. The hypotheses are empirically tested using survey data obtained from consumers in Hanoi, the capital of Vietnam. The regression results show support for most of our hypotheses. The findings indicate that two out of three facets of materialism are significant predictors of green purchase intention. Specifically, success is found to be negatively related to purchase intention, while happiness is related positively to the intention. All three antecedents in the TPB model, including attitude towards green purchase, subjective norm, and perceived behavioral control are also found to have positive impacts on purchase intention. The research findings are discussed and implications for managers and policy makers are provided.
