Abstract

Based on a critical review of the Unified Theory of Acceptance and Use of Technology (UTAUT), this study first formalized an alternative theoretical model for explaining the acceptance and use of information system (IS) and information technology (IT) innovations. The revised theoretical model was then empirically examined using a combination of meta-analysis and structural equation modelling (MASEM) techniques. The meta-analysis was based on 1600 observations on 21 relationships coded from 162 prior studies on IS/IT acceptance and use. The SEM analysis showed that attitude: was central to behavioural intentions and usage behaviours, partially mediated the effects of exogenous constructs on behavioural intentions, and had a direct influence on usage behaviours. A number of implications for theory and practice are derived based on the findings.

Highlights

The acceptance and use of information system (IS) and information technology (IT) innovations has been a major concern for research and practice
: a) attitude was influenced by facilitating conditions and social influence, b) attitude had a direct effect on behavioural intention, which implies that attitude partially mediated the effects of performance expectancy, effort expectancy, facilitating conditions, and social influence, and c) by attitude exerted a direct influence on usage behaviour
We modelled attitude to mediate the effects of exogenous constructs on behavioural intention

Summary

Introduction

The acceptance and use of information system (IS) and information technology (IT) innovations has been a major concern for research and practice. Over the last several decades, a plethora of theoretical models have been proposed and used to examine IS/IT acceptance and usage These include the Theory of Reasoned Action, the Technology Acceptance Model, the Theory of Planned Behaviour, and Model of Personal Computer Utilization (Ajzen 1991; Davis 1989; Davis et al 1989; Fishbein and Ajzen 1975; Thompson et al 1991). These theories offered different explanations of IS/IT acceptance and usage based on different factors such as technology attributes and contextual factors. While the original UTAUT model explained a considerable amount of variance in behavioural intention and usage behaviour, the model theorized some relationships that may not be applicable to all contexts, omitted some relationships that may be potentially important, and excluded some constructs that may be crucial for explaining IS/IT acceptance and use
