What are the factors determining user intentions to use AV while impaired?

In this study, we employ the Integrated Choice Latent Variable (ICLV) framework to model the public’s intention of using Autonomous Vehicles (AVs) while impaired under the influence of alcohol, medicine, or fatigue. We identify five latent constructs from psychometric indicators that define respondent’s perception and attitudes towards AVs which are i) perceived benefits, ii) perceived risks, iii) enjoy driving, iv) wheels public transport attitude, and v) rails public transport attitude. We use these latent variables along with explanatory variables to study user intentions regarding delegation of vehicle control from human driving to autonomous driving. The study uses survey data collected from 1,065 Czech residents between 2017 and 2018. Our findings indicate that user intentions are primarily defined by attitudes rather than socio-demographic attributes. However, the inclusion of both types of variables is crucial in evaluating user intentions. Despite a positive outlook towards AVs, people were found to be reluctant in using AVs while impaired which can be attributed to distrust towards the technology. Our analysis shows that with appropriate efforts from policymakers, the public’s attitude can be changed to promote adoption. The efforts will have to be emphasized towards building positive attitudes (such as perceived benefits) and diminishing existing negative attitudes (such as perceived risks).     

The ‘coming of age’ for Southern African psychobiography

This study investigated the effects of perceived values (personal, artistic, and sociocultural) of tourists’ attitude and behavioural intention to visit Africa. Participants were tourists (176 men and 124 women) who visited the Museum of African Art based on Jeju Island in the Republic of Korea. Results, following hierarchical analysis, suggest personal value and sociocultural value rather than artistic value to predict tourists’ attitude and behavioural intention to visit Africa. The findings of this study imply that personal and sociocultural predispositions lead to the tourists’ likely adoption of a tourist destination beyond familiarities with artistic works associated with the destination. Tourism promotion campaigns aimed at promoting African as a destination should customise messages to address the personal and sociocultural predispositions of would-be international tourists.     

Physically active students' intentions and self-efficacy towards healthy eating

This study investigated intentions and self-efficacy of physically active university students towards healthy eating. The application of Planned Behavior theory has shown that attitudes, intention, perceived behavioral control, and subjective norms play an important role in shaping people's behavior. 96 students, who participated in physical activities, voluntarily completed the Questionnaire for the Planned Behavior Model and the Health Behavior Questionnaire. The former examines attitudes, intentions, perceived behavioral control, and the lately added attitude strength, and role identity towards the behavior factors. The latter assesses one's efficacy expectations towards healthy eating. The regression showed strong associations between the examined variables, signifying that attitudes, perceived behavioral control, and role identity could account for one's intention towards healthy eating behaviors. On the other hand, one's self-efficacy for healthy eating could be explained from the attitudes, intention, perceived behavioral control, and attitude strength held. Overall, systematic participation in physical activities appeared to be accompanied with a relatively healthier diet, while self-efficacy had a significant association with maintaining the healthy eating behaviors. Possible interpretations, limitations, and implications for health professionals are discussed.     

Young driving learners’ intention to use a handheld or hands-free mobile phone when driving

This paper presents a survey investigating young driving learners’ intention to use a handheld or hands-free mobile phone when driving. A sample of 164 young driving learners completed a questionnaire based on the theory of planned behavior (TPB), which measured people’s intentions to use mobile phone while driving in handheld condition or hands-free condition, along with their attitudes towards the behavior, subjective norms, perceived behavioral control. The regression analysis models revealed that the TPB was able to explain 43% and 48% variance in hands-free mobile phone use intention and handheld mobile phone use intention, respectively, with perceived behavioral control emerging as the strongest predictor. In addition, TPB components, usage frequency and perceived risk were more dependent on gender than age. These results have several theoretical and practical implications. In particular, interventions should emphasize on the risk of hands-free mobile phone use when driving for young drivers, especially for young male drivers.     

The integrated model of smartphone adoption: hedonic and utilitarian value perceptions of smartphones among korean college students

Abstract This study aims to propose an integrated model of smartphone adoption that incorporates social influences (SIs), perceived technicality, as well as hedonic and utilitarian attitudes into the technology acceptance model. The proposed model was empirically evaluated by using survey data collected from 239 Korean college students to investigate their perception and attitudes toward smartphone adoption intention. Our results show that users' attitudes and their adoption intention are highly influenced by SI and positive self-image. This implies that a smartphone is a symbolic product that can signal affiliation and enhance the users' status in a group. The results also indicate that hedonic enjoyment is equally important as utilitarian usefulness in predicting the adoption intention, and the two variables mediate the relationships between SI, positive self-image, perceived technicality, and the intention to use. Consequently, the results reveal that smartphones are convergent media that can be viewed as both task-oriented and entertainment-oriented devices.     

Self-protection and growth as the motivational force behind majority group members' cultural adaptation and discrimination: A parallel mediation model via intergroup contact and threat

What motivates majority group members to adapt to or reject cultural diversity? Considering the relevance of personal values on our attitudes and behaviours, we inspected how self-protection and growth predict levels of discriminatory behavioural and cultural adaptation intentions towards migrants via intergroup contact and perceived intergroup threats, simultaneously (i.e., parallel mediation). Specifically, positive contact between groups is known for reducing prejudice through diminishing perceived intergroup threats. Yet current research emphasises the role of individual differences in this interplay while proposing a parallel relationship between perceived intergroup threats and contact. Also by inspecting cultural adaptation and discriminatory behavioural intentions, the present study examined more proximal indicators of real-world intergroup behaviours than explored in past research. Using data from 304 US Americans, structural equation modelling indicated a good fit for a parallel mediation model with growth relating positively to cultural adaptation intentions and negatively to discriminatory behavioural intentions through being positively associated with intergroup contact and negatively with perceived intergroup threats, simultaneously. The reverse was found for self-protection. These findings stress that personal values constitute a relevant individual difference in the contact/threats-outcome relationship, providing a motivational explanation for majority group members' experience of cultural diversity in their own country.     

Making the planet green again: The interplay of attitudes and group norms in the conversion to organic farming

Attitudes and social norms are key social psychological concepts that have often been considered as independent determinants of human behavior. However, questions about the interplay between the two are somewhat of a blind spot in social psychology. In the present research, we test the hypothesis that when an important change in norms is involved, behavioral intentions will be shaped by a discrepancy between personal attitudes and the perceived group norm, that is the perception of other group members’ attitudes. This proposition is tested and supported across three studies in a context of the conversion to organic farming, a behavior indicative of a significant societal and behavioral change. Farmers who did convert to organic farming were those who perceive other farmers to hold less positive attitudes toward this environmentally-friendly practice compared to their own (Study 1a & 1b, N = 1,023). Among conventional farmers, the intention to convert to organic farming is also predicted by a discrepancy between personal attitudes and the perceived group norm (Study 1b). Finally, among agricultural colleges’ students (Study 2, N = 280), the intention to become an organic farmer was influenced by an interaction between attitudes and perceived group norm and not only by independent effects of these two variables. The theoretical and practical implications of these findings for a better understanding of behavioral adaptation in times of social change are discussed.     

Antecedents of consumer loyalty in ride-hailing

The rise of the sharing economy has remarkedly shifted consumers’ traffic behaviour, which gave rise to successful start-up businesses, such as Uber and Grab, that offer innovative transport alternatives through car and ride sharing. This study investigates consumers’ traffic attitudes and behavioural responses to on-demand ride-hailing. Using structural equation modelling, our survey findings showed that price consciousness, perceived usefulness, ease of use, safety risk and customer value exert significant influences on word-of-mouth (WOM), a manifestation of attitudinal loyalty towards ride-hailing. Contrary to findings in previous studies, our study found insignificant effects of personal innovativeness, subjective norm and perceived privacy security on WOM. In addition, although environmental consciousness is a predictor of WOM, its significant effect on WOM is negative. WOM is found to significantly impact purchase intention which is an indicator of behavioural loyalty. By identifying the antecedents of consumer loyalty in ride-hailing, this study provides recommendations for the ride-hailing ecosystem to generate more sustainable urban transport solutions.     

Development and Psychometric Evaluation of the Social Justice Scale (SJS)

The study describes the development of the Social Justice Scale (SJS). Practitioners, educators, students, and other members of the community differ on their attitudes and values regarding social justice. It is important to assess, not only individuals' attitudes and values around social values, but also other constructs that might be related to social justice behaviors. The implication of Ajzen in Organizational Behavior and Human Decision Processes 50:179-211, (1991) theory of planned behavior suggests that attitudes, perceived behavioral control, and social norms predict intentions, which then lead to behaviors. A scale was designed to measure social justice-related values, attitudes, perceived behavioral control, subjective norms, and intentions based on a four-factor conception of Ajzen's theory. Confirmatory factor analysis and analyses for reliability and validity were used to test the properties of the scale.     

The influence of personal and public health and smart applications on biking behavior in South Korea

Bicycling is an important form of active transport that contributes to sustainability mobility as a result of its role in personal and public health and emissions reduction. The significance of which has grown since the COVID-19 pandemic outbreak. However, biking studies have neglected, in theoretical terms, developing an understanding of why consumers bike. Therefore, this research designs and verifies an extended theory of planned behavior adding personal and public health and a moderator of perceived smart application usage to help explain such consumer behavior. This study is based on a digital survey of South Koreans who biked for leisure, tourism, and/or work, utilizing partial least squares-structural equation modeling with multi-group analysis and Fuzzy-set Qualitative Comparative Analysis. Results revealed that personal health is most important to cyclists, followed by public health, attitude, and subjective norm. Interestingly, people with perceived high usage of smart applications for biking show stronger relationships between public health and attitude and perceived behavioral control and behavioral intention than low users. In contrast, individuals with perceived low usage of smart applications for biking reveal a stronger relationship between attitude and behavioral intention than high users. The high and low user groups of smart applications also distinctively differ in levels of cycling behavior. Consequently, this work offers several theoretical and managerial implications for research and practice.     

Positive and negative behavioural intentions towards immigrants: A question of ethnic categorisation or worldview conflict?

Anti-immigrant attitudes are often explained in terms of ethnic boundaries in which a categorical distinction between the ethnic ingroup and immigrant outgroup is made. However, these attitudes might also result from contrasting cultural worldviews. We examined the importance of ethnic categorisation and perceived cultural worldview difference in explaining behavioural intentions towards immigrants. Using an experimental survey design with a national sample of ethnic Dutch respondents (N = 832), we studied two positive and two negative behavioural intentions towards either immigrants with a contrasting cultural worldview or co-ethnics with such as worldview. Our findings indicate similar behavioural intentions towards both target groups. Furthermore, except for “the intention to learn” there were no differences in behavioural intentions towards both target groups for respondents with lower and higher authoritarian dispositions. Overall, this pattern of findings is theoretically most in line with a worldview conflict perspective rather than an ethnic boundary perspective.     

Sustainable mobility choices: Exploring the impact of consumers' values,attitudes, perceived behavioural control and subjective norms on the likelihood to choose sustainable mobility options

This study explores consumers' behaviour regarding sustainable mobility options. A mixed-methods approach was adopted to examine the impact of bio-altruistic values, egoistic values, environmental attitudes, attitudes regarding sustainable mobility, perceived behavioural control and subjective norms on the likelihood of choosing sustainable mobility options. To collect the data, an online survey was applied to a sample of 645 Portuguese consumers, which included one single non-mandatory open-ended question to understand which factors could contribute to increase respondents' likelihood to choose more sustainable transport modes. As most studies in the mobility field are quantitative, combining both quantitative and qualitative data provided a greater in-depth analysis with richer findings. Firstly, findings revealed that attitudes towards sustainable mobility, subjective norms, perceived behaviour control, and egoistic values influence the likelihood of choosing sustainable mobility options. However, environmental attitudes, altruistic and biospheric values do not impact this choice. Secondly, consumers highlight that the existence of a broad public transport network, safe bicycle lanes, and accessible prices would contribute to their likelihood of adopting more sustainable mobility behaviours. The content analysis of 402 answers allowed to discover new dimensions that influence sustainable mobility behaviour, such as safety, respect towards bicycle users, mindset adjustment, willpower, and especially physical efforts associated with long distances, bad weather, orography, and the difficulty to transport materials or other people. Based on both quantitative and qualitative findings, the paper provides key recommendations for politicians, urban planners, and transport organisations, that according to respondents, would contribute to increase their use of sustainable mobility.     

Differences in smoking attitudes of adolescents and young adults

This study employed the Theory of Planned Behavior to examine the differences between adolescent (n = 182) and young adults (n = 209) in their intention to smoke and examined possible differences. Analysis showed that young adults had more positive self-reported attitudes toward smoking than adolescents, had higher intentions to smoke, lower perceived behavioral control over smoking and perceived they were more informed about smoking. The Theory of Planned Behavior provided good prediction of intention for both young adults (R2 = .70, attitudes, information, and past behavior significant) and adolescents (R2 = .68, attitudes, past behavior significant). For both samples attitudes were the strongest predictor of intentions to smoke. Implications for understanding intention toward smoking between adolescents and young adults are discussed.     

Factors influencing car use for commuting and the intention to reduce it: A question of self-interest or morality?

Car use for commuting contributes to various environmental and traffic problems, such as pollution and congestion. Policies aimed at reducing commuter car use will be more effective when they target important determinants of car use and willingness to reduce it. This study examined whether variables reflecting self-interest (from the theory of planned behavior [Ajzen, I. (1985). From intentions to actions: A theory of planned behavior. In J. Kuhl & J. Beckmann (Eds.), Action control: From cognition to behavior (pp. 11–39). Berlin: Springer]) and variables reflecting moral considerations (from the norm-activation model [Schwartz, S. H. (1977). Normative influences on altruism. In L. Berkowitz (Ed.). Advances in experimental social psychology (Vol. 10, pp. 221–279). New York: Academic Press]) were able to explain self-reported car use for commuting and intentions to reduce it in a sample of Canadian office workers. Car use for commuting was mostly explained by variables related to individual outcomes (perceived behavioral control and attitudes) whereas the intention to reduce car use was mostly explained by variables related to morality (personal norms). The study also found that perceived behavioral control moderated the relation between personal norms and behavioral intentions: stronger personal norms were associated with stronger behavioral intentions, but only when perceived behavioral control was low. Some issues evoked by these results are discussed.     

A Comparison of Health Behavior Constructs: Social Psychological Predictors of AIDS-Preventive Behavioral Intentions

The present study focused on predicting AIDS-preventive behavioral intentions (i. e., intentions to discuss AIDS-related information and to use condoms) from constructs taken from the health belief model, the theory of reasoned action/planned behavior, and social cognitive theory. Questionnaire data were collected from 124 undergraduates using scales from previously published work as well as some new measures designed for this study. Perceived behavioral control, perceived risk, attitudes, self-efficacy, subjective norms, negative expected outcomes, and perceived severity of HIV infection were correlated with at least one intention measure; but regression analyses showed that perceived behavioral control was the strongest independent predictor of condom use intentions and of intentions to discuss AIDS information with a partner. Implications for theory and application are discussed.     

Majority versus minority influence and prediction of behavioral intentions and behavior

Two experiments examined the effects of majority and minority influence on attitude-consistent behavioral intentions. In the first experiment, when attitudes were changed via minority influence there was a greater likelihood to engage in an attitude-consistent behavioral intention than when attitudes were changed via majority influence. This suggests that minority influence leads to stronger attitudes (based on systematic processing) that are more predictive of behavioral intentions, while attitude change via majority influence is due to compliance through non-systematic processing. Further support for this interpretation comes from the finding that the amount of message-congruent elaboration mediated behavioral intention. When there was no attitude change, there was no impact on behavioral intention to engage in an attitude-consistent behavior. Experiment 2 explored the role of personal relevance of the topic and also included a real behavioral measure. When the topic was of low personal relevance, the same pattern was found as Experiment 1. When the topic was of high personal relevance, thus increasing the motivation to engage in systematic processing, attitudes changed by both a majority and minority source increased behavioral intention and actual behavior. The results are consistent with the view that both majorities and minorities can lead to different processes and consequences under different situations.
