I am using technology adoption as a dependent variable and need a reliable survey instrument. My literature review includes Socio-Technical Systems Theory, TAM, TAM2, Theory of Planned Behavior, Unified Theory of Acceptance and Use of Technology.
I advise that you adequately study the UTAUT2 model and see how it fits into your study. I am not sure of the constructs you are using. However, In addition to the construct relationships proposed in the original UTAUT, hedonic motivation and price value can determine behavioral intention. Habit can influence both behavioral intention and usage behavior. Again, facilitating conditions can affect behavioral intention.
For example, the model can be used to determine the intention of use (for mobile banking), by making these hypothesis:
Performance expectancy positively influences people’s behavioral intention to adopt mobile banking.
Effort expectancy positively influences people’s behavioral intention to adopt mobile banking.
Social influence positively influences people’s behavioral intention to adopt mobile banking.
Facilitating conditions positively influence people’s behavioral intention to adopt mobile banking.
Facilitating conditions influence people’s adoption of mobile banking.
Hedonic motivation positively influences people’s behavioral intention to adopt mobile banking.
Price value positively influences people’s behavioral intention to adopt mobile banking.
