Project description:BackgroundDue to the absence of a vaccine of SARS-CoV-2 virus pandemic, the most effective way to reduce transmission of the virus is by applying social distancing practices. Exploring factors that determine whether people adopt social distancing measures is, therefore, critical to reducing the spread of the virus. This study aimed to investigate people's intentions to socially distance based on the extended Theory of Planned Behavior.MethodsA questionnaire was distributed to the sample population and collected through social media online and WhatsApp groups from March 26, 2020 to March 29, 2020. There were 823 analyzed out of 1870 responses. The extended TPB variables and risk perception were measured using a 7-point scale (scored from 1 to 7). Data were analyzed using the partial least squares (PLS) structural equation modeling method.ResultsStudy found that the factors influencing the intention to perform social distancing were subjective norms and perceived behavior control. Risk perception affected attitudes, subjective norms, and perceived behavioral control. Media exposure was found to determine attitudes, subjective norms, and risk perceptions. The relationship between attitudes and intentions, and media use and perceived behavior control were not significant. The better and effective risk communication that can change the level of risk perception, raise family and religious leader as well as increase to control behavior are the keys to people's perform social distancing. Results from a multigroup analysis revealed that younger individuals showed a stronger relationship between the influence of risk perception and PBC and media use on risk perception. The predictive strength of subjective norms from risk perception and risk perception from media use was more strongly associated with rural populations.ConclusionsThe results of study provide an initial understanding of the level of the public's risk perception to reduce the spread of SARS-CoV-2. Findings also revealed the role of media use in determining risk perception, attitudes and subjective norms and, in turn, change people's intention to socially distance. This study may add to the literature of behavioral changes in pandemic and provide a framework for both policymakers and practitioners to formulate effective interventions in the future.

Project description:BackgroundChildbearing is the most important determinant of population fluctuations, and its study is more important than other population phenomena. Owing to the lack of a valid questionnaire based on the extended theory of planned behavior, this mixed-method study was conducted to determine the validity and reliability of a questionnaire designed to examine related belief-based factors on the intention to bear children in Iranian society.MethodsThis study was conducted in two phases in Hamadan city, western Iran, in 2021. Phase 1 consisted of an extensive literature review and a qualitative study using a directed content analysis approach to generate an item pool. Psychometrics were measured in phase 2, including content, face, and construct validity. Reliability was assessed based on internal consistency and stability. The collected data were analyzed using IBM SPSS and AMOS ver. 24.0.ResultsMean content validity ratio and content validity index were 0.7 and 0.85, respectively. Exploratory factor analysis of the 32 items identified an eight-factor solution. These factors jointly accounted for 79.1% of the observed variance in the outcome variables. Confirmatory factor analysis indicated a good fit for the data. The internal consistency based on Cronbach's α was 0.85 (0.71-0.93). In addition, stability was confirmed using the test-retest method and intraclass correlation coefficient (0.74-0.94).ConclusionThe designed questionnaire is a valid and reliable instrument for evaluating related belief-based factors on the intention and behavior of childbearing among married men and women in Iran.

Project description:This study proposed an extended theory of planned behavior (TPB) to examine the factors that influence pre-service teachers' intention to use technology-enabled learning, using constructivist pedagogical beliefs (CPB) and information and communication technologies (ICT) competencies as antecedent variables for attitudes, subjective norms (SNs), and perceived behavioral control. An online study was conducted with a random sample of pre-service teachers from 7 universities in China, and 811 validated questionnaires were obtained. The results showed that the extended TPB model explained 75% of the variance in intention; attitude, SNs, and perceived behavioral control had a positive and significant effect on intention. Furthermore, SNs had a positive and significant effect on attitude and perceived behavioral control. CPB were the antecedent variables for attitude, SNs, perceived behavioral control, and ICT competencies. ICT competencies were the antecedent variable for SNs and perceived behavioral control. Additionally, through multi-group analysis, this study found significant differences in path relationships between the lower and higher-grade groups. The effect of perceived behavioral control on intention diminished with increased grade level. The effect of SNs on perceived behavioral control reduced. The effect of CPB on attitude and perceived behavioral control on intention diminished. The effect of SNs on attitude increased. This study verified that adding the relationship between antecedent variables of theoretical factors and theoretical factors is an effective way to expand TPB and provided a reference for future studies to focus on the related intention of pre-service teachers. Furthermore, it recommends that Chinese universities should eliminate the hindering influence of CPB, ICT competencies, attitudes, SNs, and perceived behavioral control in the process of preparing pre-service teachers. They should also pay attention to the individual differences of students in different grades and the problems that arise in the existing training.

Project description:IntroductionAside from personal beliefs, young adults' intention to uptake the COVID-19 vaccine can be influenced by their fear of COVID-19 and perceived infectability of COVID-19. The present study incorporated fear of COVID-19 and perceived infectability with the theory of planned behavior (TPB) to form an expanded TPB to analyze factors affecting Pakistani young adults' intentions to uptake the COVID-vaccine in Pakistan.MethodsA cross-sectional study was conducted and recruited participants from Pakistani social media users. The proposed extended TPB model was examined by using structural equation modeling.ResultsA total of 1034 individuals replied to the survey. The three factors of the original theory of planned behavior and the fear of COVID-19 were positively related to their intention to uptake COVID-19 vaccination (r = 0.25-0.66). Moreover, the perceived infectability positively influenced the three theories of planned behavioral factors and the fear of COVID-19 (r = 0.27-0.60), also affecting the participants' intentions to uptake COVID-19 vaccination.ConclusionsPerceived infectability was positively related to the participants' intentions to uptake COVID-19 vaccination, and perceived behavioral control was the strongest mediator. More evidence-based information concerning treatments and COVID-19 vaccination are needed to encourage individuals to uptake the vaccine.

Project description:ObjectivesTheory of planned of behavior (TPB) constructs have been linked to health behavior intentions. Intentions to try mindfulness-based stress reduction (MBSR), a first-line therapy for chronic low back pain (cLBP), have been less studied. This study aimed to identify which TPB constructs could inform strategies to improve adoption of MBSR.MethodsPeople with cLBP (n = 457) read a description of MBSR then completed survey items assessing TPB constructs: attitudes, norms, self-efficacy, perceived control, and intentions to try MBSR training.ResultsStructural equation modeling showed self-efficacy/control (coefficient: 0.564), norms (0.245), and attitudes (0.131) were all positively associated with intentions to try mindfulness trainings.ConclusionsResults suggest self-efficacy/control may be the most strongly related TPB construct with intentions to try MBSR. Dissemination of MBSR for cLBP could focus on adapting the intervention to increase accessibility and improving available resources to overcome logistical barriers (online formats, drop-in classes).Supplementary informationThe online version contains supplementary material available at 10.1007/s12671-022-02022-2.

Project description:A study in Nigeria examined the psychological factors affecting face mask disposal behavior (DB) during the COVID-19 pandemic. The Theory of Planned Behavior (TPB) was used, with awareness of consequences and institutional barriers added. 1183 respondents completed an online survey, and structural equation modeling was used to analyze the data. The original TPB model revealed that attitudes, perceived behavioral control, and subjective norms explained 65% of the variance in respondents' behavior. Behavioral intention and perceived behavioral control accounted for 59.3% of the variance in DB. The extended TPB model, which included awareness of consequences and perceived institutional barriers, improved the model's explanatory power by 12.8%. Both TPB models adequately predicted face mask (FM) disposal behavior, with implications for policymakers and waste management authorities to design interventions to promote proper FM disposal behavior.

Project description:ObjectiveAdherence to adjuvant endocrine therapy (AET) in breast cancer survivors is suboptimal. Using the theory of planned behavior (TPB), this study aimed to identify the strongest predictors from the TPB of AET intentions and past behavior and assessed whether ambivalence and anticipatory emotions increased the predictive capacity of TPB.MethodsTwo hundred eighty women diagnosed with hormone positive (HR+) breast cancer who filled at least one prescription of AET responded to a survey measuring TPB constructs, attitudinal ambivalence, and anticipatory emotions. The outcomes were intentions to adhere to AET and past medication adherence (previous 2 weeks).ResultsThe TPB explained 66% of intentions to adhere to AET (P < 0.001). Ambivalence did not improve the TPB model's predictive value. When emotions were included with TPB, the model explained 70% of adherence intentions F11,226 = 52.84, P < 0.001 (R2c = .70). This increase of 4% in predictability was statistically significant (ΔR2 = 0.04), F6, 226 = 7.90, P < 0.001. Women who self-reported nonadherence in the past 2 weeks differed significantly in the TPB variables, ambivalence, and anticipatory emotions from adherent women. Nonadherent participants reported lower-future intentions to adhere F1, 236 = 5.63, P = 0.018.ConclusionsResults suggest key concepts, such as anticipatory positive emotions that should be addressed in future interventions to enhance AET adherence and survivorship.

Project description:BackgroundInfluenza remains a significant public health challenge in low- and middle-income countries (LMICs) like Bangladesh, where vaccine uptake remains low despite the substantial disease burden. Physicians play a vital role in promoting vaccination, yet their intentions and influencing factors are not well understood.MethodsWe conducted a cross-sectional study from June to October 2022 across four tertiary-level hospitals in Bangladesh using a questionnaire grounded in the Theory of Planned Behavior (TPB). Hierarchical logistic regression was employed to identify factors associated with vaccine recommendation intentions.ResultsAmong 972 physicians with an average age of 32.1 years, 40.1% intended to recommend and administer the influenza vaccine. Most (85.3%) agreed vaccination reduces risk, 65.5% desired vaccination for self-protection, 63.5% would vaccinate if available at work, and 85.3% anticipated Ministry of Health support. Male (OR = 1.9, 95% CI: 1.5-2.3) and married (OR = 1.5, 95% CI: 1.1-1.9) physicians were more likely to recommend vaccination. Each unit increase in attitude score doubled the likelihood of recommending the vaccine (OR = 2.0, 95% CI: 1.4-3.0).ConclusionsPhysicians' influenza vaccine recommendations in Bangladesh are suboptimal, influenced by gender, marital status, and attitudes. Targeted educational interventions addressing attitudinal barriers and leveraging institutional support could improve recommendation practices.

Project description:This study constructed a robust theoretical model aimed at elucidating the determinants that shape college EFL teachers' research intentions by integrating the tenets of Self-Determination Theory (SDT) with Theory of Planned Behavior (TPB). This model was empirically validated using data from 271 EFL teachers from eight colleges in China, selected through stratified sampling and collected via paper questionnaires, then analyzed using structural equation modeling. The findings underscore the instrumental roles of both autonomous and controlled motivations in driving research-related behaviors, thereby reinforcing the foundational concepts of SDT. Additionally, this study provides intricate insights into the mechanisms wherein motivation steers immediate determinants of research intention, encompassing attitudes, subjective norms, and perceived behavioral control. This melding of SDT and TPB offers an all-encompassing perspective on the multifaceted nexus between motivation and research intentions. Consequently, this refined model not only marks a pivotal stride in advancing teacher education theory but also establishes a guiding framework for forthcoming research and interventions, accentuating the imperative of fostering research intentions among college EFL educators.

Project description:Low-speed driving is an underestimated dangerous behavior that may cause safety issues, such as speed dispersion and traffic flow bottlenecks. To investigate the influence mechanism of low-speed driving behavior, this study constructed the low-speed specific model (LSSM) by extending theory of planned behavior (TPB). The LSSM incorporated two factors, namely, risk perception and behavior habit, into the standard TPB components (attitude, subjective norm, perceived behavioral control, and behavior intention). Web-based questionnaires were used to collect data from a valid sample of 374, of which males accounted for 50%. The participants were aged from 18 to 65 years (M = 35.40, SD = 0.88). The structural equation model was applied to calculate and validate the interrelationships among the components of LSSM. Results showed that the LSSM could explain the variance in low-speed driving behavior and behavior intention by 46% and 76%, respectively. Meanwhile, attitude (β = 0.52, p < 0.001) and behavior habit (β = 0.48, p < 0.001) had the strongest positive influence and prediction power over low-speed driving behavior, respectively, whereas subjective norm (β = 0.05, p > 0.01) and perceived behavioral control (β = -0.12, p > 0.01) showed few significant in influencing the intention. LSSM also showed that people who were sensitive to driving risk perception would avoid low-speed driving behaviors and attitudes. Our findings may provide theoretical support for interventions on low-speed driving behavior.
