This paper presents the findings of two studies that replicate previous work by Fred Davis on the subject of perceived usefulness, ease of use, and usage of information technology. The two studies focus on evaluating the psychometric properties of the ease of use and usefulness scales, while examining the relationship between ease of use, usefulness, and system usage. Study 1 provides a strong assessment of the convergent validity of the two scales by examining heterogeneous user groups dealing… 
Re-examining perceived ease of use and usefulness
Recently, Adams, et al. (1992) presented the results of two studies designed to replicate previous work by Fred Davis (1989) regarding perceived usefulness, ease of use, and their influence on the
Individual Differences, Perceived Ease of Use, and Perceived Usefulness in the E-Library Usage
This study examines the usage of e-library among students in a public university in Malaysia using the Technology Acceptance Model and shows that individual differences had a significant positive relationship with perceived ease of use.
A Replication of Perceived Usefulness and Perceived Ease of Use Measurement
The results of the construct measurement for perceived usefulness and ease of use in this research are quite consistent with the results reported in recent research with minor variations.
Results show that perceived usefulness is more important in determining intention to use than perceived enjoyment, and that perceived ease of use has no direct impact on intention, but still has a strong indirect effect.
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.
The Relative Importance of Perceived Ease of Use in IS Adoption: A Study of E-Commerce Adoption
The basic proposition of this study is that this varying importance of PEOU may be related to the nature of the task.
The Influence of Framing Effects on Perceived Ease of Use, Perceived Usefulness, and Behavioral Intention in Information Technology Systems
Abstract : Every year the Department of Defense spends millions of dollars on the purchase of new computer equipment. There is some question as to the necessity of the amount of this spending. This

Support is found for the hypothesis that the reliability and validity stemmed not from item grouping but from the constructs of perceived usefulness and perceived ease-of-use being clearly defined, and the items used to measure each of these constructs clearly capturing the essence of the construct.


Perceived Usefulness, Perceived Ease of Use, and User Acceptance of Information Technology
Regression analyses suggest that perceived ease of use may actually be a causal antecdent to perceived usefulness, as opposed to a parallel, direct determinant of system usage.
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,
A theoretical assessment of the user-satisfaction construct in information systems research
For nearly two decades, the user-satisfaction construct has occupied a central role in behavioral research in Information Systems IS. In industry, the construct has often been used as a surrogate for
Development of an Instrument to Measure the Perceptions of Adopting an Information Technology Innovation
The development of an instrument designed to measure the various perceptions that an individual may have of adopting an information technology IT innovation, comprising eight scales which provides a useful tool for the study of the initial adoption and diffusion of innovations.
Reducing social context cues: electronic mail in organizational communication
It is argued that electronic mail does not simply speed up the exchange of information but leads to the exchangeof new information as well, and much of the information conveyed through electronic mail was information that would not have been conveyed through another medium.
Toward a “Critical Mass” Theory of Interactive Media
A “critical mass” explanation for the diffusion of interactive media, such as telephone, paper mail systems, electronic mail, voice messaging, or computer conferencing, within communities is proposed.

An experiment is presented that explores if and how different users of the same decision-support system (DSS) differ in their perceptions of system restrictiveness. Subjects used three DSSs and
Trying to Consume
An important but relatively neglected area of consumer behavior--the pursuit of goals--is addressed. Two recent modifications of the Fishbein model are discussed, and an extension is introduced to
Diffusion of Innovations
Diffusion is the process by which an innovation is communicated through certain channels over time among the members of a social system by concerned with the spread of messages that are perceived as new ideal.
A basis for analyzing test-retest reliability
Lower bounds to the reliability coefficient that can be computed from but asingle trial are developed, to avoid the experimental difficulties of making two independent trials.
