Unified Theory of Acceptance and Use of Technology (UTAUT) which was extended from TAM with seven others (theory of reasoned action, motivational model, theory of planned behaviour and model of PC utilization) have been used by few researchers to predict acceptance.
UTAUT which was validated by [46] has been applied in a number of studies.
It should not be forgotten that Yang and Huang's study was conducted in Taiwan, and this obviously implies cultural differences not explored in the UTAUT model.
The UTAUT (Venkatesh et al., 2003) consists of four determinants: performance expectancy, effort expectancy, social expectance and facilitating conditions.
The relevance of the Unified Theory of Acceptance and Use of Technology (UTAUT) model for the suggested diffusion strategy is threefold; one is that it consolidates many of the research models and theories related to the acceptance and use of technologies and innovations; two, is that it illustrates the connection between expectancies about, intention towards, and actual usage of a technology; and three, research results indicate that time and experience with a technology serve to increase perceived values and reduce perceived complexities.
It is equally important to know that the commonly used models in technology adoption studies and specifically in cloud computing adoption studies are TAM, TOE, UTAUT, and DOI (Al-Jabri, 2014; Alharbi, 2012; Cao et al., 2013; Coursaris et al., 2013; Li & Chang, 2012).
Several models have been applied to evaluate the acceptance of technology, with the ones mostly used being the Theory of Reasoned Action (TRA) by Fishbein and Ajzen (1975), which served as a basis for other models such as The Theory of Planned Behavior (TPB) (AJZEN, 1991), the Technology Acceptance Model (TAM) by Davis, Bagozzi and Warshaw (1989), the Model of the Information Technology Diffusion Process (STRAUB, 1994), The Theory of Decomposed Planned Behavior (Taylor and Todd, 1995) the Unified Theory of Acceptance and Use of Technology (UTAUT) (VENKATESH et al., 2003) and the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2) (VENKATESH; THONG; XU, 2012).
Guo and Barnes (2012) used the unified theory of acceptance and use of technology (UTAUT) model to show that effort expectancy, performance expectancy, perceived enjoyment, and general achievements such as, performance improvement and personalization have effects on purchase intentions and that the purchase intentions and habits influence purchase behaviors [3].
To gain a comprehensive understanding of users' intention to purchase tablet computer applications, we employed an extended version of the unified theory of acceptance and use of technology (UTAUT; Venkatesh, Morris, Davis, & Davis, 2003).
