Abstract
This study investigates the impact of the perceptions of antisocial behaviour on the use of the social media platform Twitter. We extend the Unified Theory of Acceptance and Use of Technology (UTAUT) with the Perception of Antisocial Behaviour as a risk factor, and two supporting constructs: Strategic Self-Presentation and Protective Self-Presentation. We call this extended model Technology Acceptance and Use under Risk (TAUR). We investigate two groups via an online questionnaire, contrasting Anglophone countries (the UK, USA, and Canada, 200 responses), with Saudi Arabia (540 responses). In both cases the data shows that the Perception of Antisocial Behaviour impacts Twitter use, but not directly, rather it negatively impacts the influence of other factors such as Behavioural Intention - it also shows that this affects Anglophones more than Saudis. This indicates that future work should differentiate between different cultural groups, and different solutions may be needed to assuage users' fears in different parts of the world.
