Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent models, (2) empirically compare the eight models and their extensions, (3) formulate a unified model that integrates elements across the eight models, and (4) empirically validate the unified model. The eight models reviewed are the theory of reasoned action, the technology acceptance model, the motivational model, the theory of planned behavior, a model combining the technology acceptance model and the theory of planned behavior, the model of PC utilization, the innovation diffusion theory, and the social cognitive theory. Using data from four organizations over a six-month period with three points of measurement, the eight models explained between 17 percent and 53 percent of the variance in user intentions to use information technology. Next, a unified model, called the Unified Theory of Acceptance and Use of Technology (UTAUT), was formulated, with four core determinants of intention and usage, and up to four moderators of key relationships. UTAUT was then tested using the original data and found to outperform the eight individual models (adjusted R 2 of 69 percent). UTAUT was then confirmed with data from two new organizations with similar

One result of the increasing sophistication and complexity of MIS theory and research is the number of studies hypothesizing and testing for 1 V. Sambamurthy was the accepting senior editor for this paper. Carte & Russell/Moderation Errors RESEARCH ESSAY moderation effects. A review of the MIS and broader management literatures suggests researchers investigating moderated relationships often commit one or more errors falling into three broad categories: inappropriate use or interpretation of statistics, misalignment of research design with phenomena of interest, and measurement or scaling issues. Examples of nine common errors are presented. Commission of these errors is expected to yield literatures characterized by mixed results at best, and thoroughly erroneous results at worse. Procedures representing examples of best practice and reporting guidelines are provided to help MIS investigators avoid or minimize these errors.

The turn of the century has seen a rapidly graying population concurrently with increasingly ubiquitous IT. The elderly population being less familiar with IT implies that issues pertaining to their acceptance of information systems (IS) deserve special attention. However, the IS and gerontology literatures seldom explore IS acceptance among the aged. Attempting to address this gap, a research model is developed by integrating relevant antecedents from previous literature and empirically tested in the context of an e-Government service tailored for senior citizens. Our findings reveal that consistent with previous technology acceptance studies, senior citizens ’ use intention is driven by their perceived usefulness and perceived ease of use of the service. Additionally, their Internet safety perception impacts the acceptance of this online financial service. Furthermore, resource savings and self-actualization determine senior citizens ’ usefulness perception, whereas computer anxiety and computing support are antecedents of perceived ease of use. Of these antecedents, self actualization and computer anxiety appear particularly relevant for the elderly as compared to younger working professionals in most previous literature for whom these antecedents have not been important. The study contributes by providing an integrative model of IS acceptance among the aged, which may facilitate theory development and practice. Keywords: E-Government, information systems acceptance, senior citizens, perceived usefulness, perceived ease of use 1 1.

Association (IRMA) Conference. Both conferences were held in Philadelphia, PA. The current version of the study provides additional data analysis and implications. Forthcoming in Data Base for Advances in Information Systems In this paper, I examine how and why the situated knowledge and lived experiences of working-class African American women shape their standpoint on information technology (IT). Using the biblical metaphor of the exodus and narratives of ascent, these women view IT access and training as part of a strategy for escaping poverty and despair. Whereas most of the extant gender and IT research provides rich insights into the marginalization of women, the women in this study felt empowered by IT. This contradictory outcome has three implications for the study of gender and IT. First, researchers must consider the multiple identities such as gender, race, ethnicity, socio-economic status, and sexuality that shape and are shaped by women’s engagement with IT. Second, the notion of IT workforce should take into account not only the highly skilled IT workers who design and build IT artifacts, but should also consider the lower skilled workers who indirectly use IT. Third, IT training programs that serve working-class women must go beyond the transfer of IT skills to individuals. They must also redress the persistent structural barriers of poverty, spatial isolation, illiteracy, sporadic work, and racial and ethnic discrimination that systematically limit women’s ability to compete for jobs that provide higher incomes, greater safety, more security, full-time hours, increased benefits, higher status, and less stressful work environments.

This paper addresses ways in which theorizing gender may be important in forming an understanding of the topic of emancipation which is central to the new critical information systems based on Habermas’s thinking. After briefly introducing current research on gender and IS and arguing that we need to look towards feminist philosophy for appropriate theory in order to understand foundational issues such as emancipation, the paper reflects on the reasons why technical disciplines may find feminist theory threatening. The development of feminist philosophy and epistemology is introduced. Habermas’s ‘ideal speech situation ’ is problematized in relation to feminist writing on male and female communication juxtaposed with recent research in computer mediated communications. The paper continues by exploring the concept of emancipation through feminist epistemology and closes by analysing how these concerns may be applied to critical IS. 1.

In this exploratory study, Internet adoption decisions are examined from an organizational perspective. We postulate that when the technology considered for adoption demands a shift of paradigm, involves support of a corporate-wide infrastructure, and/or nascent skills of technology developers, individual-based technology adoption models may lack explanation power. This study identifies eight factors that may facilitate or inhibit technology adoption. Results from the interviews of top managers reveal that Internet technologies indeed demand the considerable deliberation in adoption decisions since Internet technologies requires a re-examination of existing business models and strategies. Yet, interestingly, this same technology was adopted with very different reasoning logic, ranging from using the Internet as an additional channel for promotion and advertisement to being pressured from competitors to adopt (the “we gotta have one, too ” syndrome). A wide range of research on technology adoption has been published during the last decade. Many of these studies have either adapted Davis’s Technology Acceptance Model (TAM) [6] by adding distinct variables [11,18] or have tested the TAM under different conditions [20,22]. The findings of these studies have furthered our understanding of the technology adoption and acceptance process. However, the issue of technology adoption has primarily focused on the understanding of individual behavior, not the adoption behavior of an entire organization. As new technology may require new infrastructure and nascent skills that are beyond individual control, it becomes necessary that researchers investigate the decisions made by those in a position to influence technology adoption for an entire organization. In addition to determining what factors influence an organization’s decision to adopt a new

Internet banking is an information intensive business and becomes a major trend in the financial marketplace. It is important to understand what factors will impact the actual use of internet banking. Therefore, this paper is aimed at analyzing the determinants of internet banking usage behavior in Korea. This study compares two models that predict an individual’s intention: Theory of Reasoned Action(TRA) and Theory of Planned Behavior(TPB). The results show that internet banking users ’ attitude and their perceived behavioral control play a vital role in influencing the behavioral intention of internet banking. However, intention is not formed by users ’ subjective norm in both TRA and TPB. In addition, attitude, subjective norm, and perceived behavioral control is, in turn, influenced by attitudinal belief structures, normative belief structures, control belief structures, respectively. Both TRA and TPB predict behavioral intention to use the internet banking quite well, with TPB having a slight empirical advantage. 1.

Information technology (IT) is fundamentally altering the way in which healthcare is delivered to consumers, and offers the promise of improving patient safety, reducing medical errors, improving efficiency, and increasing the reach of health delivery programs. The aim of this research is to examine the factors affecting the adoption and post-adoption of a significant IT innovation in healthcare: online health intervention programs that provide technology-mediated guidance and aid individuals in self-managing their health care. A key challenge confronting health program providers is that of motivating initial enrollment and subsequent continued participation in these interventions. Limited prior work in the information systems and health informatics literature has examined the uptake of technology-mediated health intervention programs. Using data from an online healthcare portal site, this study proposes and empirically tests relationships between the determinants and participation in online health intervention programs.
