A series of studies was conducted to systematically assess the impact of additions to the UTAUT model in the form of trust, social and cognitive ability variables. The overall aim was to establish a model usable for all types of technologies, including devices, services or interfaces. Starting with the well-known measures of TA and current lifestyle technology, multiple studies were carried out with participants mainly from the UK. The first study focused on E-Reader technology, and included classic TA measures as well as measures of technology trust and social aspects. These were, in parts, shown to be significant predictors of technology acceptance operationalized as Intention to Use (ITU). Based on the results from this study, TabletPC technology was examined in Study 2, confirming the established model using confirmatory factor analysis (CFA) and structural equation modelling (SEM). The focus was then shifted to cognitive aspects, which have so far been rather underrepresented in classic TA research. The new approach introduced in this research showed comparable benefits to significantly longer measures used in existing literature. The trust and social related variables did not add significantly to the model in the third study, focussing on the use of computers. The cognitive ability variables however significantly improved the model. In order to confirm initial findings regarding 'trust' related variables, a fourth study was carried out focusing on online social networks and the role that trust plays in the user interaction. This confirmed the structure of the constructs for the technology that they were initially designed for. The fifth and final study was a confirmatory study testing the established model on workplace technology. This was designed to finalize the confirmatory approach this research has been guided by: starting with workplace technology and a seemingly universal model, introducing new variables to enhance the model and allow it to predict non-workplace technology use, and finally testing it on workplace technology for its universality. The results showed that the inclusion of social variables added significantly to the amount of variance accounted for by the model. Furthermore, the structure of the resulting LTAM model showed links with previous hypotheses regarding latent links between Perceived Ease of Use and Perceived Usefulness.
