Development of an Instrument to Measure the Perceptions of Adopting an Information Technology Innovation

Abstract: This paper reports on the development of an instrument designed to measure the various perceptions that an individual may have of adopting an information technology IT innovation. This instrument is intended to be a tool for the study of the initial adoption and eventual diffusion of IT innovations within organizations. While the adoption of information technologies by individuals and organizations has been an area of substantial research interest since the early days of computerization, research efforts to date have led to mixed and inconclusive outcomes. The lack of a theoretical foundation for such research and inadequate definition and measurement of constructs have been identified as major causes for such outcomes. In a recent study examining the diffusion of new end-user IT, we decided to focus on measuring the potential adopters' perceptions of the technology. Measuring such perceptions has been termed a "classic issue" in the innovation diffusion literature, and a key to integrating the various findings of diffusion research. The perceptions of adopting were initially based on the five characteristics of innovations derived by Rogers 1983 from the diffusion of innovations literature, plus two developed specifically within this study. Of the existing scales for measuring these characteristics, very few had the requisite levels of validity and reliability. For this study, both newly created and existing items were placed in a common pool and subjected to four rounds of sorting by judges to establish which items should be in the various scales. The objective was to verify the convergent and discriminant validity of the scales by examining how the items were sorted into various construct categories. Analysis of inter-judge agreement about item placement identified both bad items as well as weaknesses in some of the constructs' original definitions. These were subsequently redefined. Scales for the resulting constructs were subjected to three separate field tests. Following the final test, the scales all demonstrated acceptable levels of reliability. Their validity was further checked using factor analysis, as well as conducting discriminant analysis comparing responses between adopters and nonadopters of the innovation. The result is a parsimonious, 38-item instrument comprising eight scales which provides a useful tool for the study of the initial adoption and diffusion of innovations. A short, 25 item, version of the instrument is also suggested.

Managerial Fads and Fashions: The Diffusion and Rejection of Innovations

Abstract: Reviews indicate that the dominant perspective in the diffusion of innovation literature contains proinnovation biases which suggest that innovations and the diffusion of innovations will benefit adopters. As a result, it is difficult to either address or begin answering the questions: when and how do technically inefficient innovations diffuse? or when and how are technically efficient innovations rejected? This article has two goals: (1) to develop a typology that focuses attention on three less dominant perspectives that can be used to guide research on these questions and (2) to suggest how organizational scientists can develop more encompassing theories of innovation diffusion and rejection by using the theoretical tensions that exist between the dominant perspective and the three perspectives developed in this article. These resolutions are important because they indicate that processes which prompt the adoption of efficient innovations may coexist with processes that prompt the adoption of ineffici...

Innovation and reinvention in state policymaking: theory and the evolution of living will laws.

Abstract: Most research on the diffusion of policy innovations focuses on the date of adoption and its correlates. This research examines an aspect of innovation which has received little attention: policy reinvention during the initial diffusion process and through amendment. The central proposition is that even though a set of laws or policies may be grouped into one broad, general category, states create substantively different policies through reinvention, which has important consequences for groups affected by the legislation. Hypotheses concerning the relationship between date of adoption and policy content and the effect of particular controversial policy provisions on reinventions are examined. The study has general implications for the study of the diffusion of innovations and policy in state politics.

Diffusion of geographic information innovations

Abstract: Appropriate diffusion of geographic information technologies is hampered by lack of systematic research on factors and processes affecting diffusion, utilization and impact assessment of the technologies and by a variety of conceptual and methodological problems. Diffusion of innovation principles developed in other fields, in combination with methods developed within the field of management information systems, provide an important beginning for improved understanding. This paper focuses on gaps in knowledge which might be addressed within the geographic information field by analysis techniques and research methodologies used in the diffusion of innovations.

Diffusion of Technologies and Social Behavior

Abstract: The diffusion of innovations is at the core of the dynamic processes that underlie social, economic, and technological change. Diffusion phenomena are not limited to the spread of new process technologies and the market penetration of new products but extend also to changes in the forms of social organization and transformations in the social fabric and cultural traits. This book is the outcome of the diffusion of the concept of diffusion as a fundamental process in society. Originating from biology, diffusion research is now carried out in many disciplines including economics, geography, history, technological change, sociology, and management science. The book illustrates the progress that has been made in understanding the nature of diffusion processes and their underlying driving forces. The contributions by leading scholars provide a novel interdisciplinary perspective and span a wide range of modeling and empirical research backgrounds.

Diffusion of Innovations Under Conditions of Uncertainty: A Stochastic Approach

Abstract: The diffusion of innovations is at the core of the pattern of technological change. Many attempts to explain and describe this process have been undertaken during the last decade and a vast bibliography of publications on this subject is presented in Rogers, 1962 and 1983; and Rogers and Shoemaker, 1971. The theory of innovation is an important part of economic and social science, and is both conceptual and formal. Their unity is a necessary premise for the success of any scientific theory.

Mathematical Models for the Diffusion of Innovations

Abstract: Models for the diffusion of innovations belong to the wider class of mathematical models for the spread of rumors and infections [1].

Finding stable support for computing in psychology: Lessons from innovation diffusion in organizations

Abstract: We present the steps that the Psychology Department, the Academic Computing Center (ACC), and the central administration at St. Olaf College have taken to integrate computing support into the operating budget of the college. In hindsight, we also propose a model of the diffusion of innovations into an organization as a theoretical guide to stabilizing support for computing in academic departments. The theoretical framework highlights the commonality between our particular adaptations and those that would most help at other institutions.
