Which of the following is NOT a component of the Technology Acceptance Model?

• A. Clinical Decision Support
• B. Perceived Ease of Use
• C. Perceived Usefulness
• D. Usage Behavior

Answer: (A)

Technology Acceptance Model centers on how people come to accept and use technology. The model focuses on two belief-based constructs: Perceived Usefulness, which is the idea that using the system will improve job performance, and Perceived Ease of Use, which is about how effortless the system is to learn and operate. These beliefs shape attitude toward use and influence the intention to use, ultimately leading to Actual System Use (often called usage behavior).

Clinical Decision Support refers to a type of clinical tool or feature, not a construct described in TAM. That’s why it isn’t part of the model. The other terms are core parts of TAM: Perceived Ease of Use and Perceived Usefulness are the key beliefs, and Usage Behavior represents the actual use that TAM aims to explain after those beliefs drive intention and attitude.
