This study explores the factors influencing the use of YouTube for English as Second Language (ESL) learning among Malaysian Lower secondary students. The rapid growth of digital platforms has altered the way students access real-world language input, yet little is known about how YouTube contributes to their learning. This research paper is guided by the Theory of Planned Behaviour (TPB), the research examines the role of attitudes, subjective norms and perceived behavioural control in shaping student’s intentions to use YouTube for learning English. A qualitative research approach was implied, with semi-structured interviews conducted with nine students from both urban and rural schools. Data were analysed using thematic analysis of Braun and Clarke’s (2006) framework. The findings resulted that students use YouTube to develop listening, vocabulary and pronunciation skills, while social influences and accessibility strongly affect their engagement. The study concludes that YouTube functions as a supplementary tool for English Learning, connecting formal classroom instruction with real-world language exposure.

The implementation of Withholding Tax (WHT) in Indonesia confronts multifaceted challenges encompassing both internal taxpayer factors—including staff understanding, motivation, and capacity—and external factors such as transaction complexity, administrative procedures, and limited system digitalization. Risks of incorrect withholding, tax avoidance, and sectoral compliance variations underscore the necessity for integrated strategic interventions. This study aims to analyze WHT challenges, identify opportunities, and examine strategies based on Tax Compliance Theory, considering taxpayers' attitude, subjective norms, and perceived behavioral control. The research employs a systematic literature review methodology, analyzing 50 peer-reviewed journals (Q1-Q3 international and S2-S3 national publications) published within the last decade. Literature selection followed rigorous inclusion criteria: studies specifically addressing WHT implementation, containing challenge and opportunity analyses, and demonstrating methodological rigor. The analytical framework utilized thematic synthesis to identify patterns across internal and external compliance factors, subsequently evaluated through the Tax Compliance Theory lens. Findings indicate that effective strategies include system digitalization, staff training, taxpayer education, incentive-penalty mechanisms, regulatory harmonization, and real-time monitoring and auditing. Notably, this study contributes novel insights by synthesizing WHT compliance challenges within the globalization context, particularly addressing cross-border digital transactions and fintech sector implications previously underexplored in Indonesian taxation literature. The integrated strategic framework proposed bridges theoretical understanding with practical implementation, offering evidence-based policy recommendations. Implementing these integrated strategies is expected to enhance voluntary compliance, minimize withholding errors, and strengthen WHT effectiveness across all sectors, including MSMEs and fintech.

The promotion and utilization of agricultural organic waste derivatives represent a critical pathway toward achieving green agricultural transformation and efficient resource recycling. Drawing upon the TPB and NAM theories, this study develops a dual-path integrated behavioral model that encompasses both rational decision-making and moral motivation. Based on 661 valid survey responses collected in the Xinjiang region of China, the study employs SEM and DEMATEL method to systematically examine the influence mechanisms of subjective norms, behavioral attitude, perceived behavioral control, personal norms, consequence perception, and responsibility attribution on consumers' willingness to consume and their actual consumption behavior of agricultural organic waste derivatives. It further identifies the causal relationships and hierarchical structure among these key variables. The findings reveal that: (1) Subjective norms, behavioral attitude, and personal norms significantly and positively influence consumer willingness, thereby promoting actual consumption behavior. Perceived behavioral control not only directly enhances willingness but also facilitates behavioral conversion; (2) Consequence perception, responsibility attribution, and subjective norms indirectly influence consumer willingness by activating personal norms, while consequence perception also enhances willingness via improvements in behavioral attitude, thus validating the mediating role of the morally-driven pathway; (3) Consequence perception, subjective norms, and perceived behavioral control emerge as the core factors within the causal structure. Their enhancement directly strengthens consumers' green consumption willingness and behaviors, while also indirectly activating other psychological mechanisms. Accordingly, the study recommends enhancing science popularization and demonstration projects to raise awareness of the ecological benefits of agricultural organic waste utilization, establishing regulations and fostering social norms to encourage green consumption, leveraging grassroots organizations to improve product accessibility, and using education and incentives to promote ethically driven, stable consumption of agricultural organic waste derivatives.

The fashion industry has grown rapidly and become one of the world’s most influential economic sectors, yet its expansion has intensified environmental problems through excessive production and large volumes of textile waste. Growing awareness of these issues has encouraged consumers to seek more sustainable alternatives, including the purchase of secondhand clothing. This shift is especially visible among younger generations who value affordability, unique styles, and environmentally responsible choices. Although the popularity of secondhand clothing continues to rise globally, insights from other countries cannot simply be applied to Indonesia due to differences in cultural norms, lifestyles, and perceptions of used goods. This study examines the factors that shape Indonesian consumers’ intentions to purchase secondhand clothing by integrating the SOR model with TPB. Environmental concern and perceived price serve as the external stimuli that influence attitudes, subjective norms, and perceived behavioral control, which subsequently determine purchase intention. Using a quantitative approach, data collection was collected by distributing questionnaire of 253 respondents across Indonesia via Whatsapp and Instagram. SEM was utilized to examine how the variables influence one another, both directly and through indirect pathways.. The findings reveal that environmental concern and price significantly shape the three TPB components, which in turn drive consumers’ intention to buy secondhand clothing. These results highlight that Indonesian consumers consider not only economic value but also sustainability aspects when making their purchasing decisions. The research results offer valuable guidance for marketing practitioners, policymakers, and future researchers, particularly in designing sustainability-oriented strategies, national awareness campaigns, and further investigations into responsible consumption behavior. Keywords: Purchase Intention, Theory of Planned Behavior, Stimulus Organism Response Model, Secondhand Clothing.

Restoring the environmental quality of lakes is essential to encourage sustainable tourism and maintain the ecological balance of conservation areas. This study has explored the dynamics of collaboration between local communities and stakeholders in managing environmental restoration in lake conservation areas in Indonesia, emphasizing the intention and support for community collaboration. By applying the Theory of Planned Behavior (TPB) as a guiding framework, this study has examined the influence of attitudes, subjective norms, perceived behavioral control, and behavioral intentions on community participation in restoration efforts. A cluster random sampling method has been utilized to survey local communities in the Lakeshore region. The study findings have revealed that positive attitudes and strong subjective norms significantly encourage collaboration intentions, while perceived behavioral control moderates’ community support and restoration initiatives. These findings highlight the necessity of aligning local perceptions with conservation goals to enhance collaborative efforts and ensure the success of sustainable lake management. This study has contributed to the understanding of community-based environmental management and provided policymakers with some applicable insights to encourage effective collaboration and sustainable tourism development.

Vietnamese national parks are ecologically sensitive areas facing increasing environmental pressures due to rising tourism activities. These parks, rich in biodiversity and cultural heritage, are vulnerable to habitat degradation, waste accumulation, and overuse of resources. Promoting pro-environmental behavioral intentions (PEBI) among visitors is crucial for ensuring sustainable tourism and conservation. While the theory of planned behavior (TPB) has been widely used to explain environmental actions, it often overlooks internal motivational factors such as personal responsibility and control beliefs. This study addresses this gap by integrating TPB with internal environmental locus of control (IELOC) factors to understand better the psychological drivers of PEBI in the Vietnamese national park context. An online survey was conducted with 360 Vietnamese participants, and Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed to test the proposed hypotheses. The results revealed that while a green consumer identity did not significantly influence environmental attitudes, other IELOC dimensions, including activism, advocacy, and recycling, had a positive impact on attitudes toward the environment. TPB constructs, including subjective norms and perceived behavioral control, significantly influenced attitudes and behavioral intentions. Attitude toward the environment also mediated several relationships between IELOC and TPB constructs and PEBI. These findings contribute to the literature by highlighting the importance of internal control beliefs and social influences in shaping sustainable behaviors in national park settings. Practical implications include targeted interventions to foster environmental stewardship among park visitors.

This study explores the key factors influencing the adoption of E-learning systems among undergraduate students in Saudi Arabia by extending the Technology Acceptance Model (TAM) with multi-level external variables. These include individual-level factors (self-efficacy, enjoyment, computer anxiety), cultural-level (subjective norms, experience), and system-level (content quality). Furthermore, the study examines the moderating effect of accessibility on the relationships between perceived usefulness, perceived ease of use, and intention to use Blackboard as a representative E-learning platform. Data collected from 400 undergraduate students at Shaqra University and analyzed using PLS-SEM. The findings indicated that self-efficacy significantly predicts perceived ease of use but not perceived usefulness. Subjective norms positively influenced only perceived usefulness. Enjoyment and experience positively affected both perceived ease of use and usefulness, while computer anxiety negatively impacts ease of use alone. Content quality demonstrates a strong positive effect on both core TAM constructs. Accessibility moderates the relationship between ease of use and intention to use Blackboard. Aligned with Saudi Vision 2030’s educational goals, these findings highlight the importance of digital infrastructure, skill development, and inclusive access in shaping students’ adoption of E-learning technologies.

Purpose This study aims to expand the theory of planned behavior (TPB) by incorporating place attachment as a mediating variable and word-of-mouth (WOM) as a moderating variable and utilizing a mediation–moderation analytical framework to explore tourists’ behavioral intention in marine leisure contexts. Design/methodology/approach This study used anonymous questionnaires and face-to-face data collection as the main survey methods and investigated water sports and marine leisure activities to explore visitors’ views when they participated in marine recreational activities. First, we used JASP to analyze the confirmatory factor analyses with all measures to determine whether the hypothesized construct model fit the data well. Second, structural equation modeling was utilized to explore the interactions of the latent variables in relation to the mediating effects. Findings This research identifies and confirms the important mediating role of place attachment and destination image in the TPB model. Additionally, considering the prevalence of internet technology, this study introduces word-of-mouth (WOM) as a moderating effect, confirming its important reinforcing function in place attachment, destination image and behavioral intention. Practical implications Practically, tourism managers should design experiential interventions – such as storytelling tours, marine heritage events or ecologically themed festivals – that cultivate emotional connection (place attachment) while reinforcing positive destination imagery. This alignment of emotional branding with tourists’ behavioral triggers informed by the TPB offers a strategic roadmap for increasing loyalty, revisit intention and social sharing behaviors, especially through WOM amplification. Originality/value The findings confirm and extend the TPB framework by demonstrating that emotional constructs, specifically place attachment, mediate the influence of TPB variables (attitudes, subjective norms and perceived behavioral control) on behavioral intention. The findings suggest that rational decision-making models can be enhanced by incorporating affective bonds to better predict behavior, aligning with recent theoretical advancements that emphasize integrated emotion–cognition models.

Binge drinking (BD) refers to repeated switches between intense and short intoxication as well as periods of abstinence. Subjective norms, drinking identity and social and enhancement motives are found to be the most dominant determinants of BD in college students. Targeting these psychosocial factors could be of public health interest in this population, in which up to one out of five students would practice BD. The purpose of our study is to evaluate the efficacy of brief BD determinants-focused procedures, namely, hypocrisy induction (HI), social identity mapping (SIM) and motivational modeling (MM) as add-on interventions to motivational interviewing (MI), compared to MI alone, in preventing BD in college students. Two hundred and forty healthy college students (University of Caen Normandy, France) will be randomized in one of three one-meeting intervention experimental arms (i.e., MI combined with HI, SIM or MM) or in one control arm (i.e., MI alone). BD scores will be collected through ecological momentary assessment (EMA) and will be used to assess the primary outcome, i.e., the decrease of self-reported BD intensity at one-month post-intervention. Secondary endpoints include self-reported alcohol drinking norms, identity, motives, frequency and craving, as well as readiness to change one's alcohol-related behaviors. Assessments are scheduled at pre-intervention as well as at one and six-month follow-up. The purpose of this study is to evaluate the complementary efficacy of HI, SIM or MM-based intervention combined with MI in an innovative prevention program aiming to target BD specific determinants and subsequently lower BD in college students.

Cesarean delivery rates have risen in recent years, often influenced by misconceptions and negative attitudes rather than medical necessity. To address this issue, the present study examined the impact of an educational intervention based on the Theory of Planned Behavior (TPB) on delivery method choice among primiparous women in Firouzabad, Iran (2024-2025). This quasi-experimental study was conducted on 100 primiparous women covered by health centers in Firouzabad County, Fars Province, Iran, from 2024 to 2025. Sampling combined cluster and simple random methods to intervention (n = 50) and control (n = 50) groups. The intervention group received six 60-minute in-person educational sessions at health centers over two months. Data were collected using a standardized TPB-based questionnaire completed by both groups before and two months' post-intervention. Data were analyzed in SPSS-27 using paired t-tests, independent t-tests, chi-square, and Fisher's exact tests. Independent t-tests showed no significant differences in mean scores of knowledge (p = 0.842), attitude (p = 0.456), subjective norm (p = 0.215), perceived behavioral control (p = 0.751), or behavioral intention (p = 0.612) between groups before the intervention. Post-intervention, however, the intervention group demonstrated significantly higher mean scores across all TPB constructs compared to the control group (p < 0.001), indicating the effectiveness of the educational program. The results of the present study demonstrated that the educational intervention based on the TPB was effective in establishing behavioral intention for selecting natural delivery type among primiparous women. This research revealed that TPB-based education, through identifying misconceptions and addressing incorrect social norms, successfully promoted behavioral intention in primiparous women, enabling them to choose the optimal delivery method according to their circumstances.

ObjectiveCardiac arrest is a leading cause of global mortality, for which timely cardiopulmonary resuscitation (CPR) is a critical intervention. However, public competence in CPR remains low. Grounded in the Theory of Planned Behavior (TPB), this study investigated the factors influencing CPR implementation among college freshmen by examining their behavioral intention.MethodsA cross-sectional study was conducted among college freshmen undergoing a basic entrance physical health screening at Fuzhou First General Hospital between September 2 and 9, 2024. Participants were randomly selected to complete an electronic questionnaire, which included a general information sheet and the validated Public Behavior Intention Scale for Performing CPR, adapted with input from emergency medicine experts. Statistical analyses included correlation, regression, and mediation analysis.ResultsAmong 4,929 valid questionnaires analyzed, a higher willingness to perform CPR was associated with undergraduate enrollment, good personal and family health status, prior CPR performance, and no history of transient loss of consciousness. Multiple linear regression identified behavioral attitude (β = 0.439), subjective norm (β = 0.272), CPR knowledge (β = 0.027), and perceived behavioral control (β = 0.070) as significant predictors of CPR behavioral intention (all P < 0.01). Mediation analysis further revealed that CPR knowledge influenced behavioral intention primarily through its effects on behavioral attitude (79.43% of the total effect), subjective norm (61.31%), and perceived behavioral control (43.67%).ConclusionBehavioral attitude serves as the principal pathway through which CPR knowledge translates into intention to act. These findings underscore that targeted CPR training in universities should address both knowledge and psychosocial factors to strengthen students’ willingness to act.

Premarital sexual behavior among adolescents remains a sensitive public health concern in conservative societies, where cultural and religious norms strictly regulate sexuality. Despite these limitations, risky behaviors persist and are influenced by environmental, familial, and media factors. This review aimed to identify and synthesize factors related to premarital sexual behavior among adolescents in conservative societies using the Theory of Planned Behavior (TPB) as a guiding framework. A scoping review was conducted according to The 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Review (PRISMA-ScR) guidelines. Relevant studies were identified in PubMed, Scopus, Cochrane, and EBSCOhost, focusing on adolescents aged 10-24 years in conservative settings. The data were analyzed thematically based on the following TPB components: attitudes, subjective norms, and perceived behavioral control. Twenty-three studies met our inclusion criteria. The factors influencing premarital sex include religiosity, peer pressure, exposure to pornography, parental supervision, and substance use. Religiosity and family communication act as protective factors, whereas exposure to pornography and peer influence increases risk. Premarital sexual behavior among adolescents in conservative societies is shaped by individual attitudes, social norms, and perceived control. Culturally sensitive sex education programs, digital literacy, and family involvement are recommended to promote safer behaviors.

The current study sought to explore the predictors of green investment behaviour among employees of star-rated hotels based on the theory of planned behaviour. This study employed the correlational cross-sectional questionnaire-based research design. In total, 374 samples were obtained through a purposive sampling technique. The measurement model and proposed research model were evaluated using partial least square’s structural equation modelling. The findings support the application of the theory of planned behaviour in understanding green investment behaviour among employees of star-rated hotels. Behavioural intention positively influences green financial behaviour, reinforced by strong effects from perceived behavioural control and subjective norms. Additionally, it offers a fresh perspective on how particular green investment knowledge influences attitudes, perceived control and subjective norms related to environmentally friendly financial behaviours. These findings suggest that interventions aimed at enhancing employees’ attitudes towards green investments and improving their perceived control over financial decisions can effectively promote green financial behaviours in star-rated hotels. Training programmes focused on increasing green investment knowledge and fostering supportive social norms could further encourage sustainable financial practices among hotel employees. Implementing these strategies may lead to more environmentally responsible financial decisions within the hospitality industry.

Background Adequate fruit and vegetable (F&amp;amp;V) intake is a key component of a healthy diet and is influenced by both psychological and environmental factors. Aim to explore determinants of F&amp;amp;V consumption among Saudi adult women, applying an extended Theory of Planned Behavior (TPB) model. Methods A cross-sectional survey recruited 476 Saudi adult women aged 18–59 across all five regions of Saudi Arabia. Data were collected using a validated online questionnaire assessing TPB constructs, socio-demographics, lifestyle behaviors, and dietary patterns. Structural equation modeling (SEM) was used to test both the original and extended TPB models. Results Participants held positive attitudes but demonstrated low adherence, consuming a mean of 3.33 F&amp;amp;V servings daily. In the original TPB model, intention, and perceived behavioral control (PBC) significantly predicted behavior (R 2 = 31%), while attitude, subjective norms, and PBC predicted intention (R 2 = 75%). The extended model explained 45% of the variance in behavior, with PBC as the sole direct significant predictor. Knowledge and family meal frequency positively influenced attitudes, while F&amp;amp;V purchasing, and a healthy diet were associated with higher PBC. Conclusion PBC emerged as the only direct predictor of behavior in the extended model. Moreover, this study highlighted the crucial role of PBC in translating intention into the actual consumption of fruits and vegetables among Saudi women. Family-centered strategies that strengthen women's confidence and skills in healthy meal planning may effectively bridge the intention–behavior gap.

This study utilizes the Theory of Planned Behavior (TPB) framework to examine the elements affecting Chinese consumers' intention to ‎adopt electric vehicles (EVs). This research systematically applies TPB's core psychological variables to the EV (electric cars) adoption ‎context in China's unique market environment. This study aims to examine the relationships between attitude, subjective norm, perceived ‎behavioral control, and intention to adopt EVs among Chinese consumers. It makes a theoretical contribution by validating the applicability of ‎TPB in China's cultural and market context characterized by collectivism, strong policy orientation, and price sensitivity. From a practical ‎perspective, the investigation furnishes policymakers and marketers with valuable information to promote the advancement of more efficient ‎strategies for EV adoption in the Chinese market. Most existing research on EV adoption has been conducted in Western con‎texts, with limited systematic examination of psychological dimensions in China's distinct cultural and market environment. While existing ‎studies focus predominantly on economic and technological factors, further development of the psychological dimension and renewable energy ‎research in the Chinese market is needed. The objective of the investigation is to address this disparity by offering empirical evidence of ‎TPB's effectiveness in predicting Chinese consumers' intention to adopt EVs.

A cognitively-sensitized stigma model of help-seeking inhibition in generalized anxiety disorder: A conceptual framework illustrated in the Chinese cultural context.

IntroductionBehavioural intention is a strong predictor of actual behaviour; however, many health interventions fail among individuals with a high intention to adopt healthy behaviours. This discrepancy, known as the intention-behaviour gap, remains a critical challenge in health promotion. The purpose of this study is to present a protocol designed to explore the predictability of perceptual factors that hinder the conversion of intention into weight loss behaviour among young adults.Methods and analysisThis study employs a sequential explanatory mixed-methods design, comprising two distinct phases. In the first phase, a quantitative cross-sectional survey with a descriptive-analytical approach will be conducted to assess the frequency of behavioural intention to lose weight and weight loss behaviours. A multistage cluster sampling method will recruit young individuals aged 18–29 years with a body mass index of ≥25 kg/m² in Malekan County, Iran. Data will be collected using a structured questionnaire that includes sociodemographic information, physical activity measurements, a dietary adherence questionnaire and items assessing subjective norms, attitudes, perceived behavioural control and behavioural intention based on the Theory of Planned Behaviour. In the second phase, a qualitative study will be conducted using a purposive sampling strategy to select participants who can provide insights into the quantitative findings. Data collection in this phase will primarily involve in-depth individual interviews. A grounded theory approach will be used to develop a comprehensive understanding of the factors that impede the conversion of intention into behaviour among young individuals.Ethics and disseminationThis protocol has been approved by the Ethics Committee of Tabriz University of Medical Sciences (IR.TBZMED.REC.1403.646). Written informed consent will be obtained from all participants. Findings will be disseminated through peer-reviewed publications, conference presentations and reports to relevant health authorities.

This study investigates the socio-psychological factors influencing Malaysian hikers’ intentions to adopt Leave No Trace (LNT) practices at Gunung Tahan, Peninsular Malaysia’s highest national park peak. Utilizing the Theory of Planned Behavior (TPB) as the guiding framework, this study examines the role of attitude, subjective norm, and perceived behavioral control in predicting hikers’ intentions to practice LNT behaviors. A quantitative survey was carried out to 278 hikers using a validated questionnaire. Findings reveal varying levels of awareness and misconceptions regarding specific LNT principles. While many respondents showed alignment with land management recommendations on several practices (M &lt; 2.62), significant gaps were observed in understanding waste disposal and considerate behavior. Specifically, 55% of hikers incorrectly perceived leaving food scraps for wildlife as appropriate (M = 4.64), and 61% considered taking breaks along the trail edge as suitable (M = 5.48). MANOVA results indicate that demographic factors—gender, hiking experience, and climber skills—significantly influence attitudes, subjective norms, perceived behavioral control, and behavioral intentions. Hiking experience showed the strongest effect (η² = .21–.26), followed by gender (η² = .24–.25), and climber skills (η² = .14). Interaction effects among these factors were also significant, indicating that these demographic characteristics collectively shape hikers’ environmentally responsible behaviors. Stepwise multiple regression analysis confirmed that attitude (β = .377, p &lt; .001), subjective norm (β = .139, p &lt; .001), and perceived behavioral control (β = .240, p = .004) together explained 53.8% of the variance in behavioral intention (R² = .538). The results underscore the importance of integrating social influence, personal agency, and demographic tailoring into LNT education strategies. These findings offer practical insights for environmental educators, park managers, and policymakers seeking to enhance environmental stewardship among Malaysia’s growing outdoor recreation community.

BackgroundBody donation remains crucial for medical education and research, yet donor shortages persist worldwide, often due to limited awareness and cultural barriers. The Theory of Planned Behavior (TPB) offers a robust framework to understand and influence donation intentions. This study evaluates the efficacy of a culturally sensitive, TPB-based educational intervention aimed at enhancing behavioral determinants related to body donation among adults in India.MethodsA quasi-experimental pre-post design was employed with 163 adult participants. The multi-component intervention included multimedia educational materials, peer discussions, motivational media, and practical guidance on registration. Participants completed a validated, bilingual TPB questionnaire assessing knowledge, attitudes, subjective norms, perceived behavioral control, and behavioral intentions immediately before and after the intervention. Statistical analyses involved paired-sample t-tests to compare pre- and post-intervention scores, multiple linear regression to identify predictors of behavioral intention, and subgroup analyses examining sociodemographic influences.ResultsPost-intervention assessments revealed statistically significant improvements across all TPB constructs (all p < 0.001). Knowledge increased markedly from a mean score of 2.7 to 3.8 (on a 0–4 scale), corresponding to a large effect size (Cohen’s d = 1.25). Attitude, subjective norms, and perceived behavioral control all showed medium effect sizes (d = 0.65–0.70). Multiple regression indicated that attitude (β = 0.40, p < 0.001), subjective norms (β = 0.32, p < 0.01), and perceived behavioral control (β = 0.26, p < 0.01) were independent predictors of post-intervention intention, jointly explaining 52% of the variance (R² = 0.52). Notably, willingness or intention to donate increased to 66% post-intervention, with higher readiness observed among participants with prior knowledge, urban residence, male gender, higher education, and older age.ConclusionThe TPB-based, culturally tailored educational intervention effectively enhanced knowledge and psychosocial determinants of body donation intention among Indian adults. These findings underscore the potential of theory-driven, culturally adapted programs to increase readiness for body donation, offering scalable strategies to address donor shortages in diverse cultural contexts globally.Supplementary InformationThe online version contains supplementary material available at 10.1186/s12889-025-25544-5.

Numerous studies have demonstrated that improving factors like family and social support, subjective norms, and attitudes—key elements of the BASNEF model—can greatly influence individuals’ health behaviors. This study evaluated whether an educational intervention based on the BASNEF model improves university students’ quality of life. It used a quasi-experimental design with 60 participants in each of the intervention and control groups. Data were collected using three questionnaires—demographics, BASNEF constructs, and quality of life—and analyzed in SPSS. In the intervention group, most dimensions of quality of life improved from pre- to post-intervention, except vitality and emotional role functioning. Significant changes were also seen in intention, subjective norms, attitude, and enabling factors. Notably, enabling factors and attitude emerged as the strongest predictors of quality of life, suggesting that future health programs should prioritize these elements. Overall, health educators and healthcare professionals can deploy the BASNEF model as a practical, cost-effective framework for modifying lifestyle behaviors and promoting positive health-related quality of life outcomes through educational interventions.
