This study aims to examine the research pattern and growth trends of published research on a unified theory of acceptance and use of technology 2 (UTAUT2) from 2012 to 2019. The study also examines the research scope of UTAUT2 for future researchers.

This study has adopted a bibliometric approach followed by a structured literature review analysis to synthesize the research on UTAUT2 since 2012. In total, 163 documents were analyzed for type of studies, theories and frameworks, methodologies, author wise collaboration, organizations that contributed to the body of knowledge in the UTAUT2 research and journals that published studies in this domain. VOSviewer and Tableau were used for the data visualization, whereas TCCM, which means theory (T), context (C), characteristics (C) and methodology (M) framework is used to propose the future research directions.

The findings reveal research on UTAUT2 is growing. The structured literature analysis of the top 15 cited articles further analyzed the parsimony of new models in detail. In addition, the study highlights the inception by and promoters of UTAUT2 in a separate section. The data for this study was collected by searching the title, abstract and keywords of documents in the Scopus database.

This study is based on research papers, published in the UTAUT2 research area, that have been extracted from the Scopus database by keywords only. Future studies can also perform a meta-analysis of various clusters generated by bibliometric analysis.

This study is useful for practitioners to devise strategies for increasing technology acceptance, adoption and utilization in the times to come.

To the best of the authors’ knowledge, this study is one of the very few and early studies, which examined patterns and growth trends of the UTAUT2 studies with the TCCM framework, to suggest scope for future research studies.

This paper investigated the extent to which the predictive power of the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) was robust against cultural variations and to what extent its predictive power could be improved by including face-valid individual differences (i.e. perceived risk and personal innovativeness) and cultural factors (i.e. individualism and uncertainty avoidance).

Data were collected from web surveys of Chinese, American and Belgian mobile Internet users (total n = 1,068).

The authors found that the UTAUT2 model was less predictive in the country where the adoption of mobile payment service (MPS) is high (i.e. China). In contrast, the UTAUT2 model was more predictive in countries where the adoption of MPS is lower (i.e. the United States and Belgium). The authors did not find additional variance explained by individual differences. Regarding the cultural variables, the authors found that individualism moderated the effect of social influence on behavioral intention to use MPS, such that the effect was more substantial among people with individualistic cultural traits. However, the authors found no moderation effect of uncertainty avoidance.

This research contributes to existing work on technology acceptance by exploring whether it is helpful to introduce individual and cultural factors into the UTAUT2 model when predicting technology adoption in different cultures. This research further examines the moderating role of cultural factors in predicting the adoption of MPS. The authors conclude that the UTAUT2 model is generally robust and appears to capture the predictive of face-valid individual and cultural factors.

The Internet of Things (IoT) offers substantial potential for improving efficiency and effectiveness in various applications, notably within the domain of smart construction. Despite its growing adoption within the Architecture, Engineering, and Construction (AEC) industry, its utilization remains limited. Despite efforts made by policymakers, the shift from traditional construction practices to smart construction poses significant challenges. Consequently, this study aims to explore, compare, and prioritize the determinants that impact the acceptance of the IoT among construction practitioners.

Based on the integrated model of Unified Theory of Acceptance and Use of Technology (UTAUT2), Task-Technology Fit (TTF), and perceived risk. A cross-sectional survey was administered to 309 construction practitioners in China, and the collected data were analyzed using structural equation modeling (SEM) to test the proposed hypotheses.

The findings indicate that TTF, performance expectancy, effort expectancy, hedonic motivation, facilitating conditions, and perceived risk exert significant influence on construction practitioners’ intention to adopt IoT. Conversely, social influence and habit exhibit no significant impact. Notably, the results unveil the moderating influence of gender on key relationships – specifically, performance expectancy, hedonic motivation, and habit – in relation to the behavioral intention to adopt IoT among construction practitioners. In general, the model explains 71% of the variance in the behavioral intention to adopt IoT, indicating that the independent constructs influenced 71% of practitioners’ intentions to use IoT.

These findings provide both theoretical support and empirical evidence, offering valuable insights for stakeholders aiming to gain a deeper understanding of the critical factors influencing practitioners’ intention to adopt IoT. This knowledge equips them to formulate programs and strategies for promoting effective IoT implementation within the AEC field.

This study contributes to the existing literature by affirming antecedents and uncovering moderators in IoT adoption. It enhances the existing theoretical frameworks by integrating UTAUT2, TTF, and perceived risk, thereby making a substantial contribution to the advancement of technology adoption research in the AEC sector.

To better understand continuities and changes in consumer behaviour, it is also important to examine the original antecedents of unified theory of acceptance and use of technology 2 (UTAUT2). Studying Generation Y is crucial for developing competitive online marketing strategies, as Generation Y plays a substantial role in online purchases. Therefore, this study aims to examine the actual use of small business websites based on the UTAUT2 among Generation Y.

A total of 375 valid questionnaires were collected via a systematic sampling among Generation Y in Canada. All participants in the study had at least a high school education, were internet and computer literate, and had purchased a good/service from the retail websites of Canadian small businesses.

The results show performance expectancy, hedonic motivation, social influence and habit have significant effects on behavioural intentions. The habit and behavioural intentions also have significant effects on actual usage of small businesses’ retail websites. Additionally, this study supported the significant difference between male and female UTAUT2 models.

The study examines how small retail businesses can attract and retain Generation Y customers by improving their website’s performance. Performance expectancy, hedonic motivation and social influence are significant factors in determining behavioral intention. Small businesses can enhance their website usability, design and content to increase customer satisfaction and loyalty. Hedonic motivation is crucial for Generation Y customers, who seek pleasure and excitement when visiting websites. Social influence is crucial for male customers, whereas performance expectancy, hedonic motivation and habit are more important for female customers. The study also suggests that Canadian governments should encourage online purchasing to increase the usage of small retail business websites.

This study provided few valuable insights into small businesses’ retail websites behavioural intentions and actual usage between males and females in Canada.

With the increasing mobile activity of the Generation Z market (born after 1994), marketers’ interest in this social group is rising. This research paper aims to uncover the relatively unknown attitudes and behaviour of the youth market in an emerging market, South Africa, towards branded mobile applications (apps). Previous studies on mobile marketing have focused on Generation X and Generation Y and generally with a quantitative focus.

This study is based on the theoretical framework of the unified theory of acceptance and use of technology model 2. The study used a qualitative framework with stratified focus groups, aged between 18 and 21 years old at a private tertiary institution in South Africa.

The findings indicate that these South African Gen Z participants mainly used WhatsApp, Instagram, Facebook, Uber and Snapchat. The participants had more positive than negative attitudes towards mobile apps. The findings also showed that privacy was a major concern for the participant’s attitudes and behaviour towards mobile apps. The findings supported the UTAUT2 model, but also discovered new themes. As a recommendation, the issue of privacy and its effect on mobile app adoption is a factor to be researched in the future. The research also provides recommendations for marketers and app developers.

This study was of a qualitative nature, and thus, the sample size was smaller than that of a quantitative study. Future research could add to this study by increasing the sample size and adding a quantitative method such as surveys.

Marketers of mobile apps targeted towards the Gen Z market should aim to be convenient for their users, as well as be entertaining, functional, time-efficient while avoiding excessive in-app adverts, being honest upfront about their pricing strategy, incorporate an element of connectivity into the app and respect their privacy. This paper also provides practical recommendations for mobile app developers (targeted towards Gen Z users) including minimising notifications and updates within the app, developing a mobile app that requires less usage of data (due to the high expense of data in South Africa for the price-conscious Gen Z market) as well as less usage of memory space on the phone and incorporating universal symbols within the mobile app.

This study supported the UTAUT2 model effects of performance and effort expectancy, social influence, facilitating conditions, hedonic motivation, price value and habit on the behavioural intention of users towards a new technology, i.e. GenZ students’ attitudes and behaviour towards branded mobile apps in South Africa. However, an additional condition was discovered in this study, i.e. privacy and its impact on the attitudes and behaviour of GenZ mobile app users. Therefore, this study extends the UTAUT2 model framework. Furthermore, this study uses a qualitative design, which has not been used in previous studies, with a focus on the under-researched Gen Z market, and in particular in an emerging market, such as South Africa.

This paper aims to analyse the unified theory of acceptance and use of technology (UTAUT) and UTAUT2 constructs used in research on information and communication technology (ICT) adoption and use among micro, small and medium enterprises (MSMEs) in non-organisation for economic co-operation and development (OECD) countries. It also investigates the areas of ICT adoption along the value chain in studies using these constructs.

Systematic literature review (SLR) was conducted, where 910 studies were retrieved manually in five academic databases. Forty-eight studies were finalised after four filtration levels.

Majority of the studies were published within the past six years, and 85.42% were studies in the form of journal papers. UTAUT constructs more researched compared to UTAUT2 constructs. More than half of the studies investigated ICT application in value chain boundaries, while 16 studies were organisation-wide studies.

With developments in MSMEs’ technology, the UTAUT2 model must be expanded to internal company operations including finance and infrastructure maintenance. To boost competitiveness and productivity, non-OECD authorities should focus on the cost and user-centric characteristics of MSMEs’ technology adoption.

Although SLRs on UTAUT and UTAUT2 constructs have been attempted previously, this study contributes to the body of knowledge by focusing analysis on the application of those constructs on MSMEs in non-OECD countries and also by situating ICT adoption along the value chain of enterprises.

This study aims to determine the factors that influence the actual behavior of Islamic digital banking customers based on the users’ perspectives during the recovery from the COVID-19 pandemic crisis.

This study used a causal exploratory method with quantitative and qualitative approaches presented in two parts. The first study (Study 1) was empirical testing of the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) used WARP-partial least square by modifying the variables of customer trust and satisfaction. A. Hayes’s PROCESS procedures were applied to examine the moderating effects of age, gender and experience. The second study (Study 2) explored the obstacles and solutions to improve digital banking services. The survey was conducted on 897 Islamic bank customers throughout Indonesia.

The results showed that all the hypotheses about the direct effect of the modification of the UTAUT2 model were supported empirically except for the effect of price value and hedonic motivation on behavioral intention, and there was just one moderating effect in this study. The other results show that 35 factors became obstacles to using digital banking.

This study had limited qualitative data collection techniques that were less deep and comprehensive. This happened because respondents were given complete confidence to fill in the open questions without any follow-up to customer answers. For further research, an in-depth interview method can be added to crucial information from the customer and expert side to get in-depth and complementary data regarding constraints and solutions. This study only used a sample of customers of Islamic banks; further research is expected to use customers of Islamic banks and conventional banks to compare their preferences for digital banking.

This study offered seven strategies that could encourage increased digital banking transactions to accelerate crisis management, mitigate cybercrime and communicate the positive impact of digital banking effectively and efficiently.

This study offered seven strategies that could encourage increased transactions using digital banking to accelerate crisis management, mitigate cybercrime and communicate the positive impact of digital banking effectively and efficiently.

Most of the existing studies focused on the modification model of the UTAUT2 model. The study is unique because it has proposed the obstacle and solution to improve digital banking service in Islamic Bank in Indonesia.

Wearable health devices (WHDs) have demonstrated significant potential in assisting elderly adults with proactive health management by utilizing sensors to record and monitor various aspects of their health, including physical activity, heart rate, etc. However, limited research has systematically explored older adults’ continued usage intention toward WHD. By utilizing the extended unified theory of acceptance and use of technology (UTAUT2), this paper aims to probe the precursors of elderly adults’ continuance intention to use WHD from an enabler–inhibitor perspective.

The research model was developed based on UTAUT2 and examined utilizing the partial least squares technique (PLS). The research data were collected through in-person meetings with older people (n = 272) in four cities in China.

Results reveal that performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic values and perceived complexity are the positive predictors of elderly adults’ continuance intention to use WHDs. Technology-related anxiety and usage cost negatively influence the formation of older people’s continuance intention.

This work is an original empirical investigation that draws on several theories as guiding frameworks. It adds to the existing literature on the usage of wearable technologies and offers insights into how the elderly’s intentions to continue using WHDs can be developed. This study broadens the scope of the UTAUT2 application and presents an alternative theoretical framework that can be utilized in future research on the usage behavior of wearable devices by individuals.

This research empirically studies consumers' continued intention to use mobile food delivery applications (apps) during the post-pandemic era in Saudi Arabia.

Using the unified theory of adoption and use of technology 2 (UTAUT2) as a theoretical model, this study collected data from a survey of 304 Saudi Arabian consumers. Structural equation modelling (SEM) was used to examine the proposed model and its hypotheses.

Social influence and performance expectancy (PE) had the strongest effects on the intention to continue using mobile food delivery apps in the post-pandemic era. In addition, effort expectancy (EE) significantly influenced PE regarding the adoption of food delivery apps. Meanwhile, EE was not an important predictor of the continued intention to use mobile food delivery apps in Saudi Arabia.

This study enriches the literature on consumers' continued intention to use food delivery apps in the post-pandemic era, a subject that has rarely been studied. In addition, this study expands the theoretical potential of the UTAUT2 model by examining the role of trust in continued intention and the effect of PE on EE in the adoption of food delivery apps during the post-pandemic era in Saudi Arabia.

This study examines the main factors influencing banking customers' behavior toward smart banking services (SBS) adoption in Pakistan. This study extends the unified theory of acceptance and use of technology (UTAUT2) by integrating information privacy concern and big brother effect into an overarching conceptualization.

This study adopts theoretical constructs from the related literature and develops hypotheses. An analysis of 385 banking customers was performed using partial least squares structural equation modeling (PLS-SEM).

The results show that most predictors of behavioral intention, including facilitating conditions, effort expectancy, habit, performance expectancy, hedonic motivation (except for social influence and price value), big brother effect and perceived information privacy concern are significant. Indeed, all predictors of use behavior are also significant. Gender and age differences between individuals further moderate the relationship between UTAUT2 constructs. Moreover, information privacy concern mediates the relationship between big brother effect and behavioral intention.

This cross-sectional study focused only on Pakistan as a developing country, which limits the generalizability of the results.

The roles of social influence and price value must be strengthened by employing marketing strategies and personalized communication. Banks should offer incentives and rewards to customers who recommend SBS to friends and family members. In addition, banks must consider the price factor when offering these services to increase their market share.

This study contributes to the field of technology adoption by providing a unique perspective of SBS adoption in Pakistan. This empirical study is the first to extend the UTAUT2 model by integrating information privacy concern and big brother effect to assess SBS acceptance and use behavior. This study examines SBS adoption issues at the national level, especially in Pakistan.
