Since Davis et al. originally formulated the Technology Acceptance Model (TAM), research on information technology (IT) acceptance has yielded many extended and competing models. Empirical investigation of these models, however, has not consistently supported the mediating role of attitude in predicting user IT adoption, leading some researchers to claim a minimal role of attitude. In this study, we call for attention to the role of attitude in explaining technology acceptance behavior. In developing the research model, we draw on both the concept of attitude strength and previous technology acceptance studies. Empirical examination of our research hypotheses indicates that attitude toward system use fully mediates the effects of salient beliefs on behavioral intention when the attitude is strong, whereas it partially mediates the effects when the attitude is weak. Our findings provide additional insights in predicting technology acceptance behavior. 相似文献

The primary aim of this study is to examine the factors that predict end users’ intention to adopt mobile government (m-government) services in a developing country. The research is based upon a self-administered questionnaire survey of 120 current users’ in the United Arab Emirates (UAE), a leader in m-government development in the Arab world. The study employs advanced statistical techniques to test an extended the Technology Acceptance Model (TAM) by incorporating the determinants of trust, cost, social influence, variety of services, perceived usefulness in information technology and demographic profiles. The findings revealed that trust and social influence are positively associated with end users intention to adopt m-government services in the UAE. By identifying the predictors of users’ adoption of m-government, this study provides several theoretical and practical implications related to m-government service adoption. 相似文献

This study is an exploratory study on the e-government in Malaysia. With the liberalization and globalization, Internet has been used as a medium of transaction in almost all aspects of human living. This study investigates the factors that influencing the intention to use e-government service among Malaysians. This study integrates constructs from the models of Technology Acceptance Model (TAM), Diffusion of Innovation (DOI) which been moderated by culture factor and Trust model with five dimensions. The study was conducted by surveying a broad diversity of citizens in Malaysia community. A structured questionnaire was used to collect data from 195 respondents but only 150 of the respondents with complete answers participating in the study. The result of the analysis showed that trust, perceived usefulness, perceived relative advantage and perceived image, respectively, has a direct positive significant relationship towards intention to use e-government service and perceived complexity has a significant negative relationship towards intention to use e-government service. While perceived strength of online privacy and perceived strength of non-repudiation have a positive impact on a citizen's trust to use e-government service. However, the uncertainty avoidance (moderating factor) used in the study has no significant effect on the relationship between the innovation factors (complexity, relative advantage and image) and intention to use e-government service. Finally in comparing the explanatory power of the entire intention based model (TAM, DOI and Trust) with the studied model, it has been found that the DOI model has a better explanatory power. 相似文献

User acceptance of a digital library system in developing countries: An application of the Technology Acceptance Model 总被引：1，自引：0，他引：1

This study examines the factors that influence people's adoption and use of a digital library system and tests the applicability of the Technology Acceptance Model (TAM) in the context of developing countries. Using data from a survey of 16 institutions in Africa, Asia, and Central/Latin America (N = 1082), a path analysis revealed that perceived ease of use of the library system had a significant impact on perceived usefulness, which ultimately led to behavioral intention to use. In addition, the study examined the similarities and differences in the significant predictors of the digital library acceptance across countries and continents. Further, the current study suggests that external variables that affect perceived ease of use and usefulness need to be considered as important factors in the process of designing, implementing, and operating digital library systems. Such consideration will help decrease the mismatch between system design and local users’ realities, and further facilitate the successful adoption of digital library systems in developing countries. 相似文献

Telehealth can be used to develop innovative healthcare services for promoting medical quality and efficiency. Despite previous research on users’ adoption intention of telehealth, users’ acceptance and resistance have rarely been considered at the same time. This study used a research model based on the dual-factor concepts of “enablers” and “inhibitors” to explain users’ intentions to utilize telehealth. We extended the Technology Acceptance Model and Status Quo Bias with the technology anxiety concept to explain why patients accept or reject the use of telehealth from the perceived enablers and inhibitors of intentions. The experimental results demonstrated users’ ambiguous and indecisive intentions of adopting telehealth. It was also found that availability and perceived usefulness are the main factors that encourage individuals to adopt telehealth services. Technology anxiety and transition costs are the key factors in discouraging people from using telehealth. Technology anxiety could be overcome through the perceived usefulness to promote the adoption of telehealth. 相似文献

The technology acceptance model (TAM) has proven to be one of the most powerful theories to explain user's technology adoption. Among many external variables incorporated into TAM, trust is considered to be an important factor that influences the user's online behavior, especially in the e-commerce context. This study conducts a meta-analysis based on the previous TAM studies in an attempt to make well-grounded statements on the role of trust. Furthermore, the paper examines those TAM studies by considering moderating effects of subject type (students or non-students) and context type (commercial or non-commercial). Results indicate a significant influence of trust on TAM constructs. Moderating effects are found for most pair-wise relationships. The findings yield implications for both researchers and service providers. 相似文献

While improving decisional quality is important to businesses, continued use of DMTs is a critical issue for managerial personnel. This problem mainly concerns the willingness of an individual to participate in the behavior. It can be further defined in a routine-based working behavior. This problem essentially involves three key issues, task fit, technology use, and habit. This study therefore integrates task-technology fit (TTF) model, expectation–confirmation mode (ECM), and habit, to examine the determinants of continued use of DMTs. Prior studies have focused on intention to use DMTs in the first time and only considered part of the three issues for identifying the determinants. 285 respondents from managerial personnel were collected to empirically evaluate this research model. The three issues are all important in influencing continuance use intention of DMTs. In particular, the task-technology fit indicates a direct effect on two factors of the technology use issue, user satisfaction and perceived usefulness, and an indirect effect on continuance use intention. User satisfaction and perceived usefulness, and habit are the key predictors of continuance use intention. 相似文献
