Re-examining the Unified Theory of Acceptance and Use of Technology (UTAUT): Towards a Revised Theoretical Model

YesBased 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

Developing a Theoretical Model to Examine Consumer Acceptance Behavior of Mobile Shopping

Part 3: Adoption and DiffusionInternational audienceMobile activity is increasing in popularity with Smartphones and Tablets being used for a variety of daily online activities. However, the number of mobile users utilizing mobile devices for the purpose of shopping is relatively low and there has been limited theoretical research examining the acceptance behavior of consumers in the UK. This research aims to develop a theoretically grounded adoption model to examine UK consumers’ mobile shopping acceptance behavior. Through consideration into findings from existing research, a theoretically grounded model is developed by extending UTAUT2 with perceived risk, trust, mobile affinity and innovativeness. This theoretical model can subsequently be empirically tested with data gathered from the UK
