This Paper aims to review IT adoption literature concerning validation and development of Unified Theory of Acceptance and Use of Technology (UTAUT). UTAUT was introduced as an accumulation of various research efforts represented in different models and theories of Technology Acceptance. The UTAUT is considered as a trial to unify terminology of variables of different models and theories of Technology Acceptance.
The theory was established on four theoretical constructs representing determinants of Use Behavior or the Intention to Use, which play essential roles as surrogates of Technology Acceptance. These constructs are: Performance Expectancy, Effort Expectancy, Social Influence, and Facilitating Conditions. In addition to these variables the theory considers also Moderating Factors which moderate the relations between various constructs and Intention to Use. The Moderators are Gender, Age, Experience, and Voluntariness of use.
It has been a decade since UTAUT was first introduced. Since then numerous studies either empirically validate or theoretically contribute to the theory. Some of them empirically validate the theory (either in western countries or across different cultures) or even replicate results of originating article. Theory validation and adaptation to be applied in different settings are briefly discussed. A literature review revealed three major trends of theoretical contributions to the theory: suggestion of New Constructs, suggestion of new Moderating Factors, and Finally Theory Extensions and Integration with other theories and models. These research trends are addressed in this Paper.
