Variance In Intention Research Articles

What factors influence the individual’s behavior in engaging in income tax evasion? An investigation using SEM and fsQCA

PurposeThe substantial rise in tax evasion raises concerns about its adverse impact on the tax system’s integrity. This article aims to empirically investigate the factors affecting income tax evasion behavior among individuals in India’s National Capital Region (NCR).Design/methodology/approachA cross-sectional design was applied to gather primary data from (N = 548) taxpayers using a “self-administered survey questionnaire.” The hybrid “partial least squares structural equation modeling (PLS-SEM) and fuzzy-set qualitative comparative analysis (fsQCA)” approach was applied to analyze the data.FindingsThis research presents a comprehensive model that explains 53.4% of the variance in behavioral intention and accounts for 51.4% in the actual behavior of individuals who participate in income tax evasion. The outcomes show that high tax burden, corruption and complexity of the tax system significantly influence behavioral intention. On the contrary, digitalization and tax morale insignificantly influence behavioral intention. Notably, behavioral intention is significantly associated with the actual behavior of individuals engaging in income tax evasion.Practical implicationsThe outcomes offer valuable implications for practitioners, including policymakers, governments and tax authorities, to effectively curb income tax evasion behavior and help them make informed decisions.Originality/valueThe innovative research model enhances prevailing knowledge by providing empirical insights into the effect of income tax evasion behavior among individuals in India. This study also contributes methodologically by combining PLS (linear) and fsQCA (nonlinear) techniques, demonstrating that both methodologies offer a deeper comprehension of the factors affecting individual behavior to engage in income tax evasion.

The Influence of Performance Expectancy, Effort Expectancy, And Social Influence on Use Behavior with Behavioral Intention as A Mediator (A Case Study of Cash on Delivery (COD) System Users in Marketplaces)

Online shopping has gained significant popularity due to the numerous conveniences it offers. Several marketplaces provide various premium services, including the Cash on Delivery (COD) payment system, which has become a prominent feature in Indonesia. COD caters to individuals who prefer traditional payment methods and are skeptical about online transactions. This payment method allows customers to mitigate concerns about potential fraud, such as non-delivery of goods or receiving empty packages, thereby offering a sense of security and trust in their purchases. This study aims to investigate the relationships between the variables of Performance Expectancy, Effort Expectancy, Social Influence, Behavioral Intention, and Use Behavior. The sample comprises individuals who have shopped on a marketplace using the COD payment system, with a total of 348 respondents. This research employs a quantitative approach, utilizing nonprobability sampling and data collection facilitated by the G-Power application. Data analysis was conducted using Smart-PLS version 4 software. The findings reveal a positive and significant impact of performance expectancy on behavioral intention, a positive and significant effect of effort expectancy on behavioral intention, and a positive and significant influence of social influence on behavioral intention. Furthermore, behavioral intention positively and significantly affects use behavior. Additionally, performance expectancy, effort expectancy, and social influence positively and significantly impact use behavior through behavioral intention.

From Online Learning to Clinical Practice: An Investigation on the Factors Influencing Training Transfer Among Physicians.

Introduction: Massive Open Online Courses (MOOCs) are an agile context for workplace training, which can provide physicians with needed knowledge and skills related to their clinical practice. From an organisational standpoint, their effectiveness can be assessed on physicians' intention to transfer what they learn through them in the workplace. Despite the Theory of Planned Behaviour (TPB) standing among the more solid models in explaining individuals' behavioural intention, its adoption in investigating the training transfer process among physicians is notably underdeveloped, limiting its contribution to enhancing the transfer rates of MOOCs content. Method: Based on such a consideration, the present study adopted an extended TPB model to investigate the potential psychosocial factors affecting the intention to transfer knowledge and skills learned through MOOCs in the workplace among 217 Italian physicians who completed an online self-report questionnaire. Results: Hierarchical regression analyses were performed, showing that among the TPB variables, perceived behavioural control and attitude significantly predicted transfer intention. The inclusion of training satisfaction and job autonomy in the model significantly increased the explained variance in intention. Conclusions: These findings have valuable implications for human resource development (HRD) in healthcare as they suggest the need to design MOOCs based on a flexible competency model in order to promote physicians' engagement and commitment to adopting new knowledge and skills. Finally, interventions aimed at recognising physicians' efforts in transferring learned content as well as empowering their ability to shape how they perform their professional duties could further enhance the impact of workplace training.

The Influence of Product Quality on Buying Interest in Tourist Souvenir Shops on the Island of Lombok

This study explores the effect of product quality on the buying interest of tourists in souvenir shops in Lombok through a quantitative research approach. Structured questionnaires were administered to a stratified random sample of 100 tourists, evaluating product quality, buying interest, service quality, store ambiance, pricing, and promotional efforts. Data collection occurred both in person and online, and the relationship between product quality and buying interest was examined with control variables like service quality and pricing. Descriptive statistics summarized the demographics, and multiple regression analysis tested the hypotheses, with reliability and validity confirmed by Cronbach's alpha and factor analysis. Ethical considerations included obtaining informed consent and maintaining anonymity. Despite potential limitations such as response bias and the specificity of findings to Lombok, the study validated the questionnaire and showed high reliability. Regression analysis indicated that product features, social influence, personal innovativeness, effort expectancy, and attitude significantly impact purchase intention. The model accounted for a substantial portion of the variance in purchase intention, offering valuable insights for local entrepreneurs and enhancing the understanding of tourism and consumer behavior.

Intention to khat chewing among youths in Raya-Azebo district, southern zone of Tigray, Ethiopia: application of the theory of planned behavior.

Khat chewing has become a global phenomenon, resulting in significant physical and mental health issues as well as socioeconomic crises. However, evidence is scarce on Ethiopian youths' behavioral intentions toward khat chewing, particularly in the Raya-Azebo district of the southern zone of the Tigray region. As a result, this study aimed to assess the intention to chew among youths in Raya-Azebo district, Southern Tigray, Ethiopia. A community-based cross-sectional survey was conducted among 627 youths in northern Ethiopia's Raya-Azebo district. Data were collected using a structured, interviewer-administered questionnaire. A multivariable linear regression model was used to predict the contribution of independent variables and identify variables strongly associated with chewing among youths. A considerable proportion, 192 (30.62%) of youths, had the intention to chew khat in the next 6 months. The component of the theory of planned behavior independently explained the variance in intention to chew by 83%. The strongest predictors of intention to chew were attitude (β = 0.35, p < 0.001), subjective norm (β = 0.297, p < 0.001), and perceived behavioral control (β = 0.15, p = 0.01). Behavioral intention toward khat chewing was a function of attitude, subjective norm, and perceived behavioral control toward khat chewing. Strategies to empower youths to change a positive attitude toward khat chewing, programs targeted at resisting social pressures, and increasing self-efficacy to combat chewing are needed.

The push-pull-mooring model of consumer service switching: a meta-analytical review to guide future research

PurposeFor nearly 2 decades, the push-pull-mooring (PPM) model has been used frequently by scholars to explain consumers’ service switching intention and behavior. However, heterogeneity and incomparability between PPM model studies are prevalent issues: The chosen predictor variables, their categorization, their measurement, reported effect sizes, and effect directions vary considerably. By addressing these issues, the present meta-analytical review enables future researchers applying the PPM model to identify relevant variables and use valid measurements.Design/methodology/approachBased on 148 empirical studies employing the PPM model, the variables used to predict consumers’ service switching intention and behavior, their frequency of use, their categorization into push, pull, and mooring factors, and their measurement are assessed. The effect sizes and directions of the relationships between these variables and consumers’ service switching intention and behavior are analyzed using meta-analytic structural equation modeling. Additionally, the predictive capacity of this model and the influence of moderators are assessed.FindingsAmong the 148 empirical studies, 382 different independent variables were used. The three most frequently used and distinctly categorized independent variables are dissatisfaction (push), alternative attractiveness (pull), and switching costs (mooring). Overall, 152 unique sources were cited to measure these variables and the dependent variables. Dissatisfaction and alternative attractiveness increase switching intention, which positively affects switching behavior, while switching costs decrease switching intention. The model explains 30% of the variance in switching intention and 31% of the variance in switching behavior.Originality/valueThis study provides the first meta-analytical review of the PPM model to guide future research systematically.

Unearthing the determinants of digital innovation adoption in the agricultural sector: The role of food security awareness and agricultural experience.

Extant research has widely acknowledged the role of digital innovation as a facilitator of digital transformation, presenting solutions for various challenges in various industries. However, prior research demonstrates inadequate discussions on the determinants of digital innovation adoption for digital transformation in developing countries, particularly in the agricultural sector. To address this gap, this study investigates the effect of food security awareness, innovation characteristics, and the moderating role of agricultural experience on behavioral intention to adopt digital innovation in the agricultural sector. A dyadic model based on diffusion innovation theory and the technology acceptance model is proposed to investigate the phenomenon. This study employed a cross-sectional quantitative approach to investigate the phenomenon based on survey data collected from 207 study participants in Ghana's agricultural sector and the partial least square structural equation modeling technique. The study's findings revealed that personal innovativeness significantly affects food security awareness (β=0.574; p<0.000), relative advantage (β=0.699; p<0.000), compatibility (β=0.687; p<0.000), and complexity (β=0.312; p<0.000). In addition, food security awareness (β=0.336; p<0.000), compatibility (β=0.257; p<0.000), and agricultural experience (β=0.238; p<0.003) significantly affect behavioral intention to adopt digital innovation. Furthermore, the study revealed that agricultural experience (β=-0.145; p<0.036) moderates the relationship between compatibility and behavioral intention. Together, these variables explain 78.9% of the variance in behavioral intention to adopt digital innovation in the agricultural sector in Ghana. The study contributes to the literature on digital innovation adoption in the agricultural sector in developing countries and proffers actionable insights for practitioners.

Health literacy and online pharmacy adoption by Saudi population using UTAUT

The field of online pharmacies is expanding rapidly and has become a crucial component in delivering pharmaceutical services across Saudi Arabia. This study aims to explore the factors influencing the adoption of online pharmacies by the Saudi population, utilizing an enhanced version of the Unified Theory of Acceptance and Use of Technology (UTAUT) framework. This study employed a cross-sectional design, utilizing an online questionnaire that was pre-validated and shared via social media channels between August 2024 and October 2024. The study focused on Arabic-speaking individuals aged &gt;18 years. The gathered data were examined through structural equation modeling (SEM) using AMOS software (v.22.0). The study found that the UTAUT model demonstrates strong applicability in explaining the adoption of online pharmacies, accounting for 62.4% (R² = 0.624) of the variance in behavioral intention. Among the key factors, effort expectancy (p &lt; 0.001) emerges as the most influential predictor of behavioral intention, followed by facilitating conditions (p &lt; 0.001) and health literacy (p &lt; 0.001). However, the analysis reveals that perceived risk (p &gt; 0.05) and personal innovativeness (p &gt; 0.05) do not have a statistically significant impact on behavioral intention. The study results would help formulate more effective strategies for establishing online pharmacy operations in developing nations like Saudi Arabia. This study contributes to enhancing the traditional UTAUT model through the integration of additional factors such as health literacy, personal innovativeness, perceived risk, and perceived trust. These variables introduce new dimensions to the existing literature on online pharmacies.

Bandung presents renowned culinary tourism known throughout Indonesia for its rich variety of culinary delights, captivating visitors and encouraging return visits. Hence, this research aims to investigate the influence of physical environment on revisit intention through perceived value at famous culinary spots in Bandung. This study employs descriptive and verificative analysis methods, utilizing questionnaires as the data collection instrument. A total of 175 respondents participated in this research. The findings reveal the presence of an influence between the physical environment variable and the revisit intention variable, with perceived value acting as a mediator.

College students’ disciplinary expertise and their entrepreneurial intentions: an exploratory study based on foreign language majors with experience in innovation and entrepreneurship training programs

Taking foreign language majors with experience in innovation and entrepreneurship training program (IETP) as samples, this study investigates the influence of disciplinary expertise on entrepreneurial intention. Based on the theory of planned behavior (TPB), a model was designed to examine the relationships among entrepreneurial intentions, perceived behavioral control, attitude toward entrepreneurship, subjective norms, IETP experience, foreign language self-efficacy and cultural intelligence. The data were collected through questionnaires and Partial least squares structural equation modeling (PLS-SEM) was adopted to test the hypotheses. The results show that: (1) perceived behavioral control and attitude toward entrepreneurship are sound predictors of entrepreneurial intentions but the influence of subjective norms on entrepreneurial intentions is insignificant; (2) IETP experience is directly related with perceived behavioral control and indirectly related with entrepreneurial intentions; (3) indicators of participants’ disciplinary expertise such as foreign language self-efficacy and cultural intelligence are directly related with IETP experience and indirectly related with entrepreneurial intentions. These six variables included in the research model account for 53.4% of the variance of entrepreneurial intentions.

Predictors of intention to stay in the profession among novice nurses: a cross-sectional study

Abstract Background Preserving new graduate nurses in the profession is an essential step for addressing the nursing shortage and sustaining the future of the profession. This study aimed to examine the relationship between employment characteristics and job satisfaction of novice nurses and their willingness to stay in the nursing profession in the next 5 years. Methods Novice nurses’ intention to stay in the profession was assessed, considering demographics, employment characteristics, and components of job satisfaction. Among the sample of 216 novice nurses (93% response rate), four components of job satisfaction were extracted and included in the multivariable logistic regression model with the intention to stay in the profession as a dependent variable. Results Professional self-accomplishment was significantly and positively associated with the intention to stay in the profession, with an elevation of one standard deviation in this component associated with more than a two-fold increase in the odds of staying (OR = 2.3, 95% CI 1.3–3.9). This component contributed 10% to the variance in intention to stay. Independently, managerial support also contributed 10% to the variance and was significantly associated with willingness to stay (OR = 1.9, 95% CI 1.2–3.0). Overall, self-accomplishment, managerial support, and healthier organizational culture were significantly associated with novice nurses’ intention to stay, whereas work conditions and rewards were not. The multivariable analysis model explained 38.0% of the variance in the intention to stay in the profession. Conclusions This study found that novice nurses’ intention to stay in the profession is highly associated with their self-accomplishment and better managerial support. Thus, to enhance the retention of novice nurses, managers must establish an environment that fosters professional development and support. This involves providing engaging work assignments, facilitating the seamless integration of novice nurses into the team, and offering managerial support and guidance.

A Model of Bystander Helping to Prevent Suicide: Examining and Extending the Theory of Planned Behavior

Research documents alarmingly high suicidal behavior risk among adolescents and young adults in the United States. A related concern is similarly high rates of exposure to the self-directed violence (SDV) of others. The current study examined how components of the Theory of Planned Behavior explain factors related to helping social network members engaging in SDV. Baseline data ( N = 4,982) from the longitudinal study, Project Lift Up, were analyzed cross-sectionally. Young people, ages 13 to 22, were recruited through social media platforms; sexual and gender minority youth were oversampled. Participants answered questions about exposure to other people’s SDV and measures of key constructs related to the Theory of Planned Behavior for helping reduce SDV including perceptions of what others think about helping and behavioral control. Three outcomes were assessed: Intent to help someone, proactive behavior to promote the other person’s mattering, and proactive behavior to prevent SDV. Measures showed adequate reliability and validity (Cronbach’s alphas above .70). Overall, regression analyses across the three outcomes partially supported the Theory of Planned Behavior. Attitudes and confidence explained variance in intent to help and proactive behavior outcomes, whereas intent and social norms showed more mixed associations with the three outcomes. While the Theory of Planned Behavior is useful to explain gatekeeper outcomes for suicide prevention, specific significant factors within the model vary by the specific outcome being examined. Further research to unpack nuances in gatekeeper behaviors is needed and may help design prevention strategies.

Measuring The Level of Cybersecurity Awareness of Social Media Users Among Students

The role of social media is increasingly important and easily accessible through mobile phones, slowly replacing conventional mass media. The development of Internet technology has made many users forget the importance of cybersecurity awareness, which impacts social media activities. As a result, cyber-attacks on social networks are now more frequent because many users still need help understanding cybersecurity well. Based on data BSSN, cyberattacks in Indonesia increased significantly from 290.3 million in 2019 to 495.3 million in 2020, representing a 41% rise. Social media users need to understand cybersecurity, a technology that protects data, networks, and programs from illegal access or digital attacks, known as cybercrime. Eighty-four respondents participated in the study. This study aims to measure the level of cybersecurity awareness and contribute to the existing literature by providing empirical insights into the level of cybersecurity awareness among university students. This study can also help raise awareness among the public, particularly young users, about the importance of protecting privacy and security while engaging in the digital world. This behaviour is measured using the five TPB variables: attitude, subjective form, perceived behaviour control, intention, and behaviour. Variables from TPB are then processed using SEM-PLS tools with the help of SmartPLS. Based on the study's results, it is concluded that the attitude and subjective form variables do not significantly affect the intention variable. In contrast, the perceived behaviour control variable significantly affects the intention variable, and the behaviour variable significantly affects intention.

Consumer Attitude and Purchase Intention towards Organic Food in Kritipur, Kathmandu

This study examined the relationship between consumer attitudes and purchase intentions toward organic products in Kritipur, Kathmandu. Using a 5-point Likert scale survey, data from 57 respondents were analyzed through correlation and regression techniques. The results reveal a considerable positive impact of consumer attitudes, specifically health concerns and environmental care, on purchase intention, with an unstandardized coefficient of 0.854 (p &lt; .001). Consumer attitudes explained 64.7% of the variance in purchase intention, confirming the critical role of favorable attitudes in promoting organic product purchases. However, contrary to the hypothesis, subjective norms had a negative influence on purchase intention (β = -0.261, p = .004), indicating that social pressures may decrease consumer willingness to buy organic products. The findings suggest that marketers should focus on increasing consumers' trust in organic products and emphasize the health and environmental benefits to increase sales. This study expands existing theoretical models by incorporating health concerns and environmental care as crucial factors influencing consumer attitudes towards organic food.

E-WOM across digital channels: A comparison of e-commerce and social media impact on consumer purchase intentions

This study analyzed by comparing the effect of e-WOM (electronic word-of-mouth) virtual shopping websites and e-WOM from respondents on social networks on users’ smartphone buying intentions. A research frame is established based on four e-WOM components: e-WOM source credibility, e-WOM source quality, e-WOM source attitude, and e-WOM source format toward the purchase intention of a smartphone. The effect of the independent variables was empirically tested using multiple regression analysis on the dependent variable of customer buying intention. The research was conducted in Uttar Pradesh, a province in India, with 362 respondents administering a questionnaire. Descriptive statistics, ANOVA (analysis of variance), and regression analysis were applied to interpret the source data. The results of regression factors had a strong statistical influence with a probability value of .000 and R2 of .358 according to the outcomes, suggesting that the framework described 35.8 proportion of the variance and that all the factors were major antecedents of buying intention. This study assists digital businesses in determining consumer buying trends through e-WOM on digital platforms. This study proposes a novel concept to understand how e-WOM affects customers’ buying intent from social networks and e-commerce portals. AcknowledgmentThis study is supported via funding from Prince Sattam bin Abdulaziz University project number PSAU/2024/R/1445.

According to the coefficient of determination, the independent variables accounted for 53.2% of the variability in purchase intention, with the remainder being influenced by unexamined factors. The implications of this study indicate that live streaming-based marketing strategies and the provision of online customer reviews are effective in increasing buying interest on social media, especially on the TikTok Shop platform. This research supports the importance of utilizing interactive features to strengthen consumer trust and product attractiveness in the e-commerce market.

Restoranlarda balık tüketimi: Planlı davranış teorisi ve yiyecek neofobisi üzerine bir araştırma

In this study, consumers' intention to consume fish in restaurants was explored by expanding Ajzen's (1985) theory of planned behavior (TPB). The food neophobia (FN) variable was added to the variables of attitude, subjective norm (SN) and perceived behavioral control (PBC), which are the main independent variables of the TPB, and the moderator role of the variable of FN between the variables of attitude and intention to consume fish was also controlled. A questionnaire was used to reach a total of 517 participants in Antalya/Türkiye. For the analysis of the obtained data, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and multiple linear regression analyses were performed using SPSS and Lisrel package programs. It was found that the variables of attitude, SN and PBC have a significant and positive effect on consumers' intention to consume fish in restaurants. Also, the FN variable had a significant and negative effect on consumers' intention to consume fish in restaurants. Finally, FN variable had a significant moderator effect between the variables of attitude and intention to consume fish. In short, individuals with high FN may not translate a positive attitude toward eating fish into a strong intention to consume it, while those with low neophobia may do so more effectively. FN alters the link between attitude and intention, highlighting its role in shaping fish consumption decisions. This research offers key insights for public health and the food industry. Findings can guide healthy eating campaigns, marketing strategies, product development, and efforts to promote sustainable fish consumption, while also considering the impact of social norms within behavioral economics.

User and Gratifications Theory in Knowing Donation Intentions During Live Streaming

This study investigates the factors that influence viewers' donation intentions to content creators in the context of live streaming in Indonesia by applying the Uses and Gratifications Theory (UGT). This research framework focuses on four independent variables, namely entertainment, escapism, social interaction, and social identity, which influence the dependent variable of donation intention. This quantitative study involved 189 respondents through a purposive sampling technique, with data collected using an online questionnaire and analyzed using regression analysis. The results show that the research model explains 52.7% of the variance in donation intention, with all independent variables contributing statistically significant (p &lt; 0.05). Entertainment is the factor with the largest influence (β=0.829), followed by social interaction (β=0.358), social identity (β=0.178), and escape (β=0.141). These findings emphasize the importance of entertainment value, emotional connection, and community identity in motivating financial support from audiences. This research provides important insights for content creators and digital platforms to increase audience engagement and monetization through content strategy management.

Effects of Resilience and Personal Accomplishment on the Relationship Between Quality of Work Life and Turnover Intention Among Newly Employed Nurses.

Turnover among newly employed nurses is an indicator of workforce stability in healthcare organizations. The factors influencing turnover intention in this group are complex and differ by generation. The relationships among variables including work-life quality, personal accomplishment, resilience, and turnover intention have been explored separately. However, a knowledge gap exists in terms of scholarly understanding regarding the respective impacts of perceived personal accomplishment and resilience on the relationship between work-life quality and turnover intention. This study was designed to explore the respective effects of resilience and personal accomplishment on the relationship between work-life quality and turnover intention. A cross-sectional approach was used, and 387 newly employed nurses who had worked for just 1 month at six medical centers in Taiwan were enrolled as participants. The following four instruments were used for data collection: Quality of Nurse Work-life Scale, Connor-Davidson Resilience Scale, the personal accomplishment subscale of the Maslach Burnout Inventory, and Turnover Intention Scale. Hayes PROCESS analysis method was used to analyze the influence of resilience and personal accomplishment on the relationship between work-life quality and turnover intention. There was a positive correlation among work-life quality, resilience, and personal accomplishment, and a negative correlation was found between all three variables and turnover intention. Resilience was found to negatively mediate the relationship between work-life quality and turnover intention ( B = -.032, p < .001). The moderating effect of work-life quality on personal accomplishment was significant ( B = .012, p < .05). Work-life quality and sense of personal accomplishment explained 61% of the variance in resilience. Work-life quality and resilience explained 50.5% of the variance in turnover intention. Furthermore, sense of personal accomplishment moderated the mediating effect of resilience on the relationship between work-life quality and turnover intention. Resilience mediates the relationship between work-life quality and turnover intention, whereas personal accomplishment may moderate the mediating effect of resilience in the relationship. Administrators should provide strategies to improve professional competence and improve psychological capacity in new nurses to increase their sense of personal accomplishment and resilience to decrease turnover intention.

A064: An Experimental Study on PE Teachers' Motivational Style Change on Adolescents' Physical Activity

Research background: Realistic demands: The decline of adolescents' physical health has been the focus of global attention. Current needs: Youth physical activity needs to be improved. Key issue: The interest and motivation of adolescents to participate in physical activity are generally low. Ways to improve: physical education can effectively promote the physical activity of teenagers in their leisure time. It is of great theoretical and practical value to study the integration of planned behavior theory and self-determination theory to explain adolescents' leisure time physical activity behavior to promote physical activity level using physical activity interventions. Research method: Mainly through the experimental method, 8 classes, 4 experimental classes and 4 control classes in the first grade of junior middle school were selected, with 40.32 students in each class. The proportion of males and females in the experimental group was 50.2% and 49.8% respectively. In the control group, the proportion of males and females was 51.0% and 49%. By changing the teacher's motivation style, this paper explored the influence of the social situation provided by PE teachers on the youth's leisure time physical activity. Research result: There were gender differences in the variables of high-intensity physical activity and behavioral intention in leisure time. Male students had higher high-intensity physical activity during leisure time than female students, with the mean value 37.90 vs. 26.27, t(448) =5.82, p &lt; 0.01, and the mean value of behavioral intention was 3.90 vs 3.42, t(448) =3.58, p &lt; 0.01. In univariate analysis of variance, students with different family social status had significant differences in the variables of subjective norm (F(2,447) =4.31, p &lt; 0.05) and high-intensity physical activity during leisure time (F(2,447) =3.87, p &lt; 0.05). There were no differences in the 8 index variables of student origin and BMI. Research conclusion: The change of PE teacher's motivation style can improve the level of teenagers' demand support perception and autonomous motivation, and obviously improve students' physical activity cognition and actual participation.
