Valid measurement scales for predicting user acceptance of computers are in short supply. [] Key Method Definitions of these two variables were used to develop scale items that were pretested for content validity and then tested for reliability and construct validity in two studies involving a total of 152 users and four application programs. The measures were refined and streamlined, resulting in two six-item scales with reliabilities of .98 for usefulness and .94 for ease of use. The scales exhibited hgih…

A Model of the Antecedents of Perceived Ease of Use: Development and Test†

Data from three experiments supported the hypothesis that an individual's perception of a particular system's ease of use is anchored to her or his general computer self-efficacy at all times, and objective usability has an impact on ease-of- use perceptions about a specific system only after direct experience with the system.

On the Test-Retest Reliability of Perceived Usefulness and Perceived Ease of Use Scales

Adams, et al. (1992) replicated the work of Davis (1989) on the test-retest reliability of the perceived usefulness and perceived ease of use scales and found both scales to have the same validity and reliability characteristics as the study.

Perceived Usefulness, Ease of Use, and Usage of Information Technology: A Replication

Two studies that replicate previous work by Fred Davis on the subject of perceived usefulness, ease of use, and usage of information technology focus on evaluating the psychometric properties of the ease ofUse and usefulness scales, while examining the relationship between ease ofuse, usefulness, and system usage.

Perceived Usefulness, Perceived Ease of Use, and Social Influence: Intention to Use e-Wallet

Research on the acceptance of the use of information technology often uses the Technology Acceptance Model (TAM) and the Unified Theories of Acceptance and Use of Technology (UTAUT) model, which

Determinants of Perceived Ease of Use: Integrating Control, Intrinsic Motivation, and Emotion into the Technology Acceptance Model

This work presents and tests an anchoring and adjustment-based theoretical model of the determinants of system-specific perceived ease of use, and proposes control, intrinsic motivation, and emotion as anchors that determine early perceptions about the ease ofuse of a new system.

The role of satisfaction and participation in technology acceptance

The Technology Acceptance Model (TAM) suggests that two factors predict computer acceptance behaviour: perceived ease of use, and perceived usefulness. User participation is also believed to

Technology Acceptance Measure for Teachers:T-TAM

Investigation of technology acceptance theories and factor structures of scales based on these theories resulted in Teacher Technology Acceptance Measure (T-TAM) scale’s statistical model, which was thoroughly investigated through parsimonious statistical procedures.

Predicting Users' Continuance Intention Toward E-payment System: An Extension of the Technology Acceptance Model

This paper synthesized the technology acceptance model (TAM), to explain and predict the users' intentions to continue using e-payment system, and revealed correlation among perceived usefulness and attitude to use, perceived ease of use and perceived usefulness, perceived eased use and attitude, and enjoyment and continuance intention.

Modeling the Determinants of Perceived Ease of Use

Test extensions of the Technology Acceptance Model (TAM) aimed at predicting senior consumers’ acceptance and use of self-service banking technologies (SSBTs) indicated that selfefficacy, technology discomfort, perceived risk and personal contact were determinants of perceived ease of use and perceived usefulness.



User Acceptance of Computer Technology: A Comparison of Two Theoretical Models

Computer systems cannot improve organizational performance if they aren't used. Unfortunately, resistance to end-user systems by managers and professionals is a widespread problem. To better predict,


This study investigates organizational factors related to user involvement in information system development and perceived system usefulness. Using a sample of 118 usermanagers in 34 companies, the


The perceived usefulness of information is an important construct for the design of management information systems. Yet an examination of existing measures of perceived usefulness shows that the

An empirical study of the impact of user involvement on system usage and information satisfaction

The results demonstrate that user involvement in the development of information systems will enhance both system usage and the user's satisfaction with the system.

Development of an instrument measuring user satisfaction of the human-computer interface

Frequent and sophisticated PC users rated MDA more satisfying, powerful and flexible than CLS, and future applications of the QUIS on computers are discussed.

Alternative Measures of Systems Effectiveness: Associations and Implications

The relationship between user perceived effectiveness measures (user satisfaction) and behavioral measures of system effectiveness (system use) is examined and the effect of system sophistication on MIS effectiveness is examined.

Training End Users: An Exploratory Study

A conceptual model of how training can impact the acceptance of information systems within the organization and an extensive field study of 100 middle- and upper-level managers indicate that a positive relationship exists between the computer-related training an individual receives and his/her computer- related ability.

Early Diagnosis of MIS Implementation Failure: Promising Results and Unanswered Questions

The results strongly suggest that users who hold realistic expectations prior to implementation are more satisfied with the system and use it more than users whose pre-implementation expectations are unrealistic.
