Meta-analysis of driving behavior studies and assessment of factors using structural equation modeling

The aim of this paper is to understand the factors that influence unsafe driving practices by examining published studies that utilized the Theory of Planned Behavior (TPB) to predict driving behavior. To this end, it reviews 42 studies published up to the end of 2021 to evaluate the predictive utility of TPB by employing a meta-analysis and structural equation model. The results indicate that these studies sought to predict 20 distinct driving behaviors (e.g., drink-driving, use of cellphone while driving, aggressive driving) using the original TPB constructs and 43 additional variables. The TPB model with the three original constructs is found to account for 32% intentional variance and 34% behavioral variance. Among the 43 variables researchers have examined in TPB studies related to driving behavior, this study identified the six that are commonly used to enhance the TPB model’s predictive power. These variables are past behavior, self-identity, descriptive norm, anticipated regret, risk perception, and moral norm. When past behavior is added to the original TPB model, it increases the explained variance in intention to 52%. When all six factors are added to the original TPB model, the best model has only four variables (perceived risk, self-identity, descriptive norm, and moral norm); this model increased the explained variance to 48%. The influence of the TPB constructs on intention is modified by behavior category and traffic category. The findings of this paper validate the application of TPB to predict driving behavior. It is the first study to do this through the use of meta-analysis and structural equation modeling.

Predicting perceived exclusive breastfeeding behavior among higher education female students in Saudi Arabia: Application of the theory of planned behavior using structural equation modeling.

The decision for infant feeding behaviors is often made early in life, based on the socio-cultural context. Thus, exploring this issue and its influencing factors can create Exclusive Breastfeeding (EBF) culture among future mothers. This study aimed to predict EBF behavior among female higher education students in Saudi Arabia through the application of the Theory of Planned Behavior (TPB) using Structural Equation Modeling (SEM). This descriptive exploratory research was conducted on three university campuses in three cities (Dammam, Jeddah, and Abha). A multistage cluster random sampling was employed to select 600 female students using a digital survey containing three sections: Personal Data and Previous BF Exposure, EBF Knowledge Scale, and The TPB constructs for the EBF scale (attitude, Subjective Norms/SN, Perceived Behavioral Control/PBC, intention, and Perceived Behavior). The results showed that the highest percent of the participants had moderate BF exposure (63.8%) and knowledge (65.7%), positive attitude (85.8%), high SN (66.2%), moderate PBC (75.8%), high intention (55.2%), and positive perceived behavior (55.2%). The SEM had acceptable fit indices were χ2/df ratio=3.817, GFI=0.935, RMSEA=0.044, NFI=0.942, CFI=0.951, PCFI =0. 924. It showed that the EBF attitude (β=0.607), SN (β=0.123), and PBC (β=0.158) were significant positive and direct predictors of the EBF intention (P <0.001). Both intention (β=0.213) and PBC (β=0.226) were significant positive and direct predictors of the perceived behavior (P <0.001). It accounted for 49.5% of the variance in EBF intention and 70.0% for the behavior. The BF exposure and knowledge were significant positive predictors of EBF intention (β=0.158, β= 0.237) and behavior (β=0.140, β= 0.207) (P=0.000). Thus, the TPB has a good predictive ability for EBF intention and behavior among the studied Saudi female university students. Thus, it can be employed for efficient health promotion and the development of EBF-friendly policies.

Urban tourists' intention towards visiting national parks: an exertion of theory of planned behaviour and expectancy theory

PurposeThis study aims to evaluate the key factors affecting the behavioural intention of urban tourists towards visiting national parks by integrating the theory of planned behaviour (TPB) and expectancy theory (ET).Design/methodology/approachData were collected from urban tourists using an online questionnaire developed through Google forms. A total of 489 valid online questionnaires were considered for this study. The proposed research model was empirically evaluated using the structural equation modelling method.FindingsAccording to the results of this research, TPB constructs are significantly and positively associated with the behavioural intention of urban tourists towards visiting national parks in India and out of ET constructs, only expectancy and valence are significantly and positively associated with behavioural intention while instrumentality does not.Research limitations/implicationsThis study manifests the behaviour of urban tourists towards national parks and contributes to academics by incorporating existing literature. The findings of this study also help policymakers in formulating innovative strategies for national parks. It presents an integrated framework that lays the platform for a new study domain on urban tourists' intentions to visit national parks, which will be useful to urban managers, officials and the tourism sector. Furthermore, as the scope of this study is confined to assessing the intentions of urban tourists toward visiting national parks, it is difficult to generalize the findings.Originality/valueTo the best of the authors' knowledge, this is the first research of its kind to provide an understanding of the behavioural intention of urban tourists towards visiting the national parks in India by optimizing the TPB and ET.

Expanding the Theory of Planned Behavior to Explain Energy Dense Food Intentions among Early Adolescents in Indonesia

The aim of this study is to examine an extended model of the Theory of Planned Behavior (TPB) and increase insight into the intentions to consume energy-dense food among adolescents in Indonesia. This study included 411 adolescents from private schools who reported their intentions to consume energy-dense food the next day and the next week, as well as attitudes, subjective norms, descriptive norms, and perceived behavioral control regarding energy-dense food consumption. Linear regression analyses (in R) were conducted to examine associations of TPB determinants (model 1), TPB determinants plus descriptive norms (model 2), and interactions between determinants (model 3) with the intention to consume energy-dense food the (1) next day or (2) next week. Attitudes and subjective norms were positively associated with both the ‘next day’ and ‘next week’ energy-dense food intentions (model 1), although associations for the ‘next day model’ appeared to be stronger. Descriptive norms, compared to subjective norms, were more strongly associated with ‘next week intentions’, whereas both norms (descriptive and subjective) did not differ in how strongly they were associated with ‘next day’ intentions (model 2). Significant interactions between TPB constructs were found for the model predicting ‘next day’ intentions (i.e. subjective norms × attitude and attitude × PBC) (model 3). Our study provides important information about proximal food intentions among collectivistic cultures specifically, which may have crucial implications for future preventive interventions.

Determinants of halal food purchase decisions for Go Food and Shopee Food users

Indonesia is one of the world’s biggest halal food product and service consumers. The halal industry will continue to expand as the Muslim community’s needs grow. Therefore, application development for online halal food providers through the Go Food and Shopee Food platforms is in high demand. This paper aims to analyze the determinants of Go Food and Shopee Food users’ halal food purchase decisions. The theory of planned behavior (TPB), the theory of consumer behavior, and the unified theory of acceptance and utilization of technology (UTAUT2) were used. The research sample consists of Go Food and Shopee Food users chosen randomly from a pool of 104 respondents. The data were collected using a questionnaire developed from previous studies and the theories applied (TPB and UTAUT2). Respondents received questionnaires online via Google Forms. Path analysis was used in this study. The findings show that TPB constructs can adequately explain halal food purchase behavior. The attitude toward the purchase of halal food and subjective norms affect the user’s intentions to purchase halal food. The coefficients are 0.291 and 0.379, with a p-value &amp;amp;lt; 0.001. The user’s intention determines the positive decision to purchase halal food with a coefficient of 0.843 and a p-value &amp;amp;lt; 0.001. Halal awareness is a powerful predictor with a coefficient of 0.206 and a p-value of 0.014. However, perceived behavioral control, halal literacy, religious commitment, financial literacy, and UTAUT2 constructs (price value, hedonic motivation, and habit) were not found to determine the intention to purchase halal food.

Intention to drink alcohol among rural natives of Sarawak: An application of the Theory of Planned Behavior

The use of alcoholic beverages is increasing worldwide, and it is the reason for the increase in mortality as well as health consequences. The rare explorations on alcohol consumption (AC) among Sarawak Natives indicated that risky drinking among the target ethnicities is higher compared to that of other ethnic groups. This study aims to identify the predictors of alcohol consumption (AC) among Sarawak Natives. The theory of planned behavior (TPB) was applied in this study to predict the intention to drink among the rural adult community in Malaysia. A cross-sectional study was conducted among rural natives of Sarawak. The sample of this study consists of 293 rural adult communities who completed an adapted and reliable survey questionnaire assessing the constructs of TPB. Study factors such as attitudes (ATT), subjective norms (SNs), and perceived behavioral control (PBC) were proximal in predicting the intention to drink alcohol. Using the path analysis, the strongest proximal predictor of intention was ATT. The results of this study revealed that study factors namely ATT, SNs, and PBC have a direct and significant effect on the intention to drink among Malaysian rural adults. Therefore, policymakers have to launch an awareness campaign to increase the knowledge about the risk of drinking alcoholic beverages and enlighten people about the danger and health problems they might face if they continue to drink alcohol. Keywords: Alcohol consumption, attitudes, intention, social factors, subjective norms, theory of planned behavior.

Willingness to receive and provide resources in Europe's non‐remunerated and remunerated collaborative consumption

AbstractRooted in theory of planned behavior (TPB) supplemented with self‐determination theory (SDT), this study explores determinants of willingness to receive and provide resources in Europe's non‐remunerated and remunerated collaborative consumption (CC). The exploration was conducted within a single research model by assessing the role of (a) TPB constructs reflecting attitude towards participation in CC, perceived social pressure to engage, and perceived level of difficulty that engagement requires and (b) SDT constructs of environmental, social, and economic motives for participation. The data were collected through an online questionnaire, and the structural relationships were analyzed using structural equation modeling. Willingness to consume in non‐remunerated and remunerated CC was positively directly influenced by social pressure to engage in CC and participation being perceived as pleasant, negatively by the level of difficulty that engagement requires, as well as positively indirectly influenced by environmental concern and sociability. Additionally, environmental concern had positive direct effect on willingness to consume only in the remunerated context. Willingness to provide in non‐remunerated CC was positively directly influenced by perceiving participation as pleasant and indirectly by environmental concern and sociability. Resource provision in remunerated CC was not explained by any of the determinants.

Application of the theory of planned behaviour to HIV management and prevention in sub-Saharan Africa: a systematic review

ABSTRACT Around 70% of global Human Immunodeficiency Virus (HIV) diagnoses are in sub-Saharan Africa (SSA), where sexual transmission remains the primary mode of HIV transmission. Poor outcomes among persons living with HIV (PLHIV) in SSA are linked to delayed diagnosis, poor linkage to HIV care and suboptimal adherence to antiretroviral therapy (ART). This study is a systematic review of published articles on the application of the theory of planned behaviour (TPB) to HIV prevention and management in SSA. A systematic search was conducted in Google Scholar, Embase, Scopus and PubMed and institutional library searches. The search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A study conducted in South Africa in 2012 revealed that TPB explained 12% of the variance in intention to adhere to ART. This was slightly higher in Tanzania where the TPB constructs explained 14.7% of intention to adhere to ART. Interestingly the variance was much higher in Malawi where attitudes, subjective norms and perceived behavioural control explained 55% of the variance of intention to adhere to ART. Studies conducted in Ghana, Tanzania, Ethiopia and South Africa revealed that attitude towards the behaviour was a predictor of intention to use condoms consistently. Among all the constructs of the TPB, subjective norms and attitudes towards the behaviour were found to have the most influence on the intention to adhere to ART and consistent condom use. Interventions to improve HIV management and prevention in SSA using the TPB should focus on the significant proximal constructs.

Do trust in financial institution and financial literacy enhances intention to participate in stock market among Indian investors during COVID-19 pandemic?

This research aims to investigate the significance of trust in financial institution and financial literacy in the investment decision-making of individual investors during the COVID-19 pandemic and investigates the strength of the theory of planned behavior (TPB) in this framework. This study considered a structured questionnaire to collect data from 460 individual investors of different districts in four states of India. For testing the research hypotheses, SPSS and PLS-SEM were taken into consideration. The findings enlighten that elements of TPB, i.e. attitude (ATT) and subjective norms (SNs), are significantly associated with investment intentions (INT) while perceived behavioral control (PBC) displays an insignificant association with INT. Furthermore, along with the original components of the TPB model, Trust in financial institution (TFI) and Financial Literacy (FL) were also incorporated in the model, which shows a significant affect on investors’ intention to invest in the stock market. The results stated that TFI is the most significant factor that enhances investors’ intention to participate in stock market during COVID-19 pandemic. The study describes that during the phase of uncertainty like COVID-19 pandemic trust is the most important factor that enhances investors’ participation in the stock market. Authors suggest SEBI and other financial institutions should promote trust and trusting behavior in financial institutions as it is significant not only from the perspective of financial development but also to empower the individuals to gain from institutional services as well as to guard them, from possible negative effects (like financial frauds), which are more likely to be present outside of regulatory boundaries. This study is one of the initial attempts in the context of the Indian Stock Market to introduce TFI as a dual (both mediating and moderating) variable between the basic constructs of TPB. Further, the study also examines the importance of trust in financial institution and financial literacy in enhancing investors’ intention to participate in stock market during COVID-19 pandemic.

Seat belt use among rural non-drivers: the role of demographic and traffic-related variables.

The rate of seat belt use in rural societies is less than in urban societies. The present study aimed to determine the effect of demographic and traffic-related variables on seat belt use among rural non-drivers based on the theory of planned behavior (TPB). This study was conducted among 450 non-drivers in the rural areas of Hashtroud district in Iran. For collection of data, a questionnaire containing questions about demographic characteristics and general information on traffic-related behaviors of non-drivers, and questions on seat belt use based on constructs of the TPB was used. The lowest seat belt use rate was for non-drivers that sit in the rear seat of a car on rural roads (22.4 % never, 14.4 % always). Also, the rate of seat belt use among parents of participants on rural roads was lower than on city roads. Adherence to traffic rules and having training about seat belt use had significant effects on the construct of TPB, including attitude, subjective norms, perceived behavioral control, behavioral intention, and behavior of seat belt use. With increasing age, subjective norms about seat belt use have improved. The attitude toward seat belt use among females was better than males. The result indicated that most of rural non-drivers did not adhere to traffic rules. Adherence to the traffic rules and having training on seat belt use had a significant impact on seat belt use behavior. Training seat belt use especially by parents could be effective in improving seat belt use.

Exploring preference and willingness for rural water pollution control: A choice experiment approach incorporating extended theory of planned behaviour

Rural water pollution control (RWPC) is a crucial issue for developing countries, particularly because of its importance for improving ecosystems, promoting sustainable development, and ultimately contributing to the health and well-being of individuals. This study adopted a choice experiment (CE) to explore farmers' preference and willingness for RWPC and to investigate whether socioeconomic and psychosocial factors can explain differences in farmers’ preferences and values governing RWPC. The theory of planned behaviour (TPB) and some additional constructs (risk perception, knowledge, moral norms, and subjective norms) were included in an empirical test that predicts stated choices. The Wei River basin, one of the most water-polluted areas in China, was used as the location for our study. From June to July 2022, we collected the questionnaire responses of 427 farmers who live and work in this area. The results suggested that farmers have significant heterogeneity in their preference for RWPC attributes, but the majority highly value improving water quality through water pollution treatment. The inclusion of TPB and additional constructs in our test explained the behaviour of farmers. Those with high scores tended to already perform RWPC and have a willingness to continue to do so. According to the results of a latent class (LC) model, the average willingness to pay (WTP) per farmer for rural water pollution treatment was 254.69 Chinese yuan (CNY) per year. Excluding biodiversity, the average WTP was 241.55 CNY per year. This study provides a new path for developing countries to promote RWPC and improve local rural environments and the well-being of rural residents.

Application of the extended theory of planned behavior in predicting the behavioral intentions of Iranian local communities toward forest conservation.

Natural forests are the habitat of many plant and animal species and are the main source of genetic reserves. In addition to preserving biodiversity, forests play an important role in the livelihood and income of many indigenous communities. But, in the last few decades, due to the lack of proper management of the beneficiaries, they have been exposed to destruction, so that their protection requires the participation of all members of the society, especially the local people. Therefore, the main goal of this research was to discover the determinant factors on the intention of local communities to protect forests in Iran. An extended theory of planned behavior (TPB) by adding the variables of "risk perception" (RP) and "sense of belonging to place" (SBP) was used as the theoretical framework of the research. This research was done using the questionnaire survey method and with the help of structural equation modeling (SEM). The statistical population of this study included all the rural communities living in the Arasbaran forests (located in the northwest of Iran). The research findings indicated that the original TPB explains 66.9% of the variance of the behavioral intentions of locals toward forest protection. The three main constructs of the original TPB included attitude, perceived behavioral control (PBC) and subjective norms (SN), all of which had positive effects on the intention of local communities. Most importantly, the extended TPB by including RP and SBP increases the ability of the model to explain the intentions of local communities to forest protection by 11.8%. In this study, the variable of RP was identified as the most important factor, so it is suggested to the policy-makers of this field to increase the RP of local communities in relation to forest destruction using communication media. It is also suggested to promote safe behaviors in these natural areas through developing forest protection organizations and properly training locals on the protection of forest areas.

How psychological factors affect speeding behavior: Analysis based on an extended theory of planned behavior in a Chinese sample

Speeding, the most frequent traffic offense, is a key contributor to road crashes. This study explores the psychological factors affecting drivers’ speeding behavior (exceeding the posted speed limit by more than 10%) based on the extended theory of planned behavior (TPB). The scale incorporating TPB constructs and additional variables (Type A personality, risk perception, and driving habit) was developed to collect empirical data, and 945 valid samples were obtained. The reliability and validity of the developed scales were verified, and a structural equation model of drivers’ speeding behavior was established to explore the causal relationship between speeding behavior and psychological characteristics and the interrelationships between TPB variables (speeding intention, attitude, subjective norm, and perceived behavioral control), explicit cognition predictors (risk perception and Type A personality) and implicit habitual factors (driving habit). The results showed that speeding intention and driving habit positively correlated with self-reported speeding behavior. In addition, attitude and risk perception positively correlated with speeding intention. Although Type A personality trait had no significant effects on speeding behaviors, it had significant effects on attitude and risk perception. In addition, the results of the mediation analysis demonstrated that speeding intention, driving habit, and attitude toward speeding are the most influential factors. Attitude and risk perception have a significant indirect effect on speeding behavior mediated by speeding intention. Drivers’ attitudes, driving habits, and risk perception played a mediating role in the relationships between Type A personality traits and speeding behavior. The findings yield insights into useful information and directions for designing road safety interventions, developing driver education and training programs, and strengthening social messaging aimed at the general public.

Risk-Taking, Financial Knowledge, and Risky Investment Intention: Expanding Theory of Planned Behavior Using a Moderating-Mediating Model

This research examines the impact of financial knowledge on risky investment intention via the lens of the theory of planned behavior (TPB). The research developed a comprehensive model to test the mediation effect of the three TPB antecedents on the link between financial knowledge and risky investment intention. The research investigates the moderating effect of risk-taking on the link between three TPB constructs and risky investment intention. For these purposes, we used a pre-tested survey, was directed to senior university students in public universities in Saudi Arabia. The findings of SmartPLS showed a significant positive influence of financial knowledge on attitudes towards risky investment, subjective norms (SNs), and perceived behavioral control (PBC). Both SNs and PBC have a significant positive influence on risky investment intention. Nonetheless, the personal attitude of students failed to have a significant direct or mediating influence on risky investment intention. Additionally, risk-taking did not have a moderating effect on the link between personal attitude and risky investment intention. Students belong to a risk-adverse culture, which could justify the insignificant impact of their personal attitudes on risky investment intention. On the other side, SNs and PBC have a mediating effect on the link between financial knowledge and risky investment intention. Risk-taking has a moderating effect on the link between SNs, PBC, and risky investment intention. The research extends the use of TPB by validating its assumptions about driving the investment intention of university graduates.

Understanding Pro-Environmental Behaviors and Intentions in Visitors to a Zoo-Based Seal Encounter

Increasing pro-environmental behavior may combat environmental deterioration and promote animal and human welfare. Using the Theory of Planned Behavior (TPB), we investigated how an Australian zoo-based seal encounter influenced participants’ pro-environmental intentions and behavior at 1-month follow-up. Participants were 113 seal encounter visitors, with n = 29 providing 1-month post-encounter data. Pre-encounter, participants reported past and intended pro-environmental behaviors, and TPB constructs (attitudes, perceived behavioral control, subjective and moral norms). Post-encounter, participants rated their experience and future pro-environmental intentions. At 1-month follow-up, participants again reported their pro-environmental behaviors. The model explained past pro-environmental behaviors and future behavioral intentions (but not plastic use specifically), with subjective norms being the most important. Unlike past research, moral norms were not significant, perhaps due to the zoo-based research context. Importantly, participants reported a decrease in plastic use 1-month post-encounter. These findings provide suggestions for zoos to design encounters targeting subjective norms to promote pro-environmental behavior.

Applying a Combination of SEM and fsQCA to Predict Tourist Resource-Saving Behavioral Intentions in Rural Tourism: An Extension of the Theory of Planned Behavior.

How to save resources and protect the environment at destinations is one of the hot issues in tourism. One effective solution is to cultivate tourist resource-saving behavioral intentions (TRSBI). Prior studies mainly use Structural equation modeling (SEM) to explore its antecedents, whereas other potential methods (i.e., fuzzy-set qualitative comparative analysis, fsQCA for short) have been less adopted. This study combines SEM and fsQCA to examine TRSBI in a rural tourism context. Specifically, SEM is executed to investigate how environmental concern influences TRSBI based on the theory of planned behavior (TPB), while fsQCA is applied to uncover the multiple configurations in the TRSBI formation. The findings from SEM indicated that (1) environmental concern positively and directly influenced TRSBI; (2) TPB constructs (i.e., attitudes toward the behavior, subjective norms, and perceived behavioral control) positively and separately mediated the associations of environmental concern with TRSBI. The fsQCA outcomes showed that three configurations result in a high level of TRSBI: (1) high attitudes toward the behavior, subjective norms, and perceived behavioral control, (2) high attitudes toward the behavior, subjective norms, and environmental concern, and (3) high attitudes toward the behavior, perceived behavioral control, and environmental concern. The combined approaches offer a systematic and holistic solution to explore TRSBI in rural tourism.

Applying an extended prototype willingness model to predict back seat safety belt use in China

&lt;abstract&gt; &lt;p&gt;The risk of injury and death in traffic accidents for passengers in the back and front seats can be reduced by utilizing safety belts. However, passengers use back seatbelts far less frequently than those in the front. More investigation is therefore required into the psychological constructs that affect individuals' attitudes toward using back seat belts. In this study, four models were used to analyze individual intentions and actual back seat belt use: the standard theory of planned behavior (TPB); the standard prototype willingness model (PWM); a model that integrates the TPB and PWM constructs; and a model that integrates the TPB construct, PWM constructs, descriptive norms and perceived law enforcement. The results showed that the standard PWM has much more explanatory power than the standard TPB in explaining the variance in behavioral intention and behavior. Incorporating perceived behavioral control (PBC) into the standard PWM did not improve the model fit considerably, while incorporating descriptive norms and perceived law enforcement moderately improved the model fit. Attitude greatly impacted behavioral intention and the use of back seat belts, followed by perceived law enforcement and descriptive norms, while subjective norms, prototype favorability, prototype similarity and PBC had no significant effect.&lt;/p&gt; &lt;/abstract&gt;

The moderating role of individualism/collectivism in predicting male Chinese university students' exercise behavior using the theory of planned behavior

The purpose of this study was to check the moderating role of individualism/collectivism in predicting male Chinese university students’ exercise behavior using the theory of planned behavior (TPB) model. The TPB model was validated through SEM (structure equation model), and the moderating effect of individualism and collectivism was validated through a hierarchical regression and simple slopes analysis using a sample collected from 115 male Chinese university students. The results showed that the product terms of individualism and TPB factors were not able to significantly predict exercise intention after inclusion in the regression equation, nor were the product terms of collectivism and PBC (perceived behavior control) able to do so. However, the product terms of collectivism and attitude, as well as collectivism and SN (subjective norm) were able to significantly predict exercise intention when included in the regression equation. That is, horizontal and vertical collectivism can significantly moderate TPB constructs, primarily by moderating the relationship between attitude-exercise intention and SN-exercise intention. This study found that the predictive validity of exercise attitudes on exercise intentions in TPB constructs is greater only at low levels of horizontal and vertical collectivism and low at high levels. The predictive validity of SN is greater at high levels of horizontal and vertical collectivism and low in the inverse case. This research serves to enrich the theoretical framework for the theory of planned behavior and provides useful information for understanding university students’ exercise intentions and behaviors.

Effect of Educational Intervention Based on Theory of Planned Behavior (TPB) on Doing Breast Self-examination in a Sample of Iranian Women.

Breast self-examination (BSE) is an important part of health care for all women in every stage of life. This study aimed to investigate the effect of theory of planned behavior (TPB) on doing BSE in a sample of Iranian women. A cross-sectional study was carried out to examine the factors affecting the BSE in 400 women. Then, a quasi-experimental study was conducted on 200 subjects (100 in experimental group and 100 in control group). The educational intervention for the experimental group consisted of 8 training sessions. A questionnaire including demographic characteristics, knowledge, and constructs of TPB was used to measure BSE performance before and 6 months after the intervention. Constructs of attitude, subjective norms, and perceived behavioral control predicted the intention to do the BSE. The mean age of the subjects was 31.65 ± 7.59 years. The studied variables predicted 38.7% of behavioral intention (P < .001, odds ratio = 0.387). Six months after the intervention, the experimental group showed a significant increase in the knowledge, attitude, perceived behavioral control, subjective norms, intention, and BSE performance compared with the control group (P < .001). This study showed that educational intervention based on the TPB was effective in promoting breast cancer screening behavior such as BSE. Therefore, it is suggested that health educators and health care planners use educational texts based on these constructs of TPB to increase their influence on individuals via screening behavior for breast cancer.

Mask-Wearing Onboard Airplanes During COVID-19 - Identifying Passenger Segments Using Cluster Analysis

The COVID-19 crisis has had an unprecedented impact on air traffic, but its long-term effect on how people view and conduct air travel could be more significant. While some studies have identified factors that can affect the perception of COVID-19 and behaviors in transportation, few have examined factor impact at the segment level, especially with respect to mask-wearing as a protective measure onboard airplanes during COVID-19. This study fills the research gap by identifying passenger segments with different perceptions of mask use onboard airplanes, and which factor in the theory of planned behavior (TPB) model can be best distinguished in the different segments. Survey data was collected from MTurk for cluster analysis, which considered the comfort of mask-wearing, risk avoidance, and information-seeking jointly as the cluster variates. The analysis led to the formation of three passenger segments: 1) Comfort First – most attention was paid to the comfort of mask-wearing; 2) Risk Avoider – the greatest importance was given to avoiding the risk and searching for information about COVID-19; and 3) Balanced Group – having a balanced view on the importance of the three cluster variables. The multinomial logistic regression analysis showed that the three passenger segments differed most in their attitude toward masks, suggesting that attitude, compared to the other two TPB constructs (subjective norms and perceived behavioral control) can best predict the cluster membership of air travelers with regards to mask-wearing onboard airplanes. The findings provide useful guidance for the airline industry to recover safely and effectively from the COVID-19 pandemic, and may aid in preparations for future pandemics.
