The unified technology-acceptance measure consolidating eight earlier models into four core determinants of intention and use.
| Construct measured | Technology acceptance (performance expectancy, effort expectancy, social influence, facilitating conditions) |

| Number of items | About 4 items per construct (the validated core model uses 4 items each for PE, EE, SI, FC plus 3 behavioral-intention items) |
| Response format | 7-point agreement scale (1 = Strongly disagree to 7 = Strongly agree), items adapted to the focal technology |
Construct reliabilities are commonly reported above .80, often above .90, in the original longitudinal studies and later applications.
Items were selected from eight predecessor models and validated longitudinally across organizations, explaining substantially more variance in intention than any single prior model; an enormous replication literature (and citation record) supports the nomological network, with UTAUT2 extending it to consumer settings.
Organizational technology users originally; UTAUT2 targets consumers; used globally across e-government, m-banking, health IT, education and more.
