Construct
Definitions Attitude: Individual's

(e.g., using a system). Behavioral
intention: The

anxiety: The degree of an

faced with the possibility of using computers. Computer
playfulness: The degree of cognitive
spontaneity in microcomputer interactions. Computer
self-efficacy: The degree to which
an individual beliefs that he or she has the ability to perform
specific task/job using computer. Effort
expectancy: The
degree of ease associated with the use of the system.Facilitating
conditions: The
degree to which an individual believes that an organizational and
technical infrastructure exists to support use of the system.Image: The
degree to which use of an innovation is perceived to enhance one's
status in one's social system.Job
relevance: Individual's
perception regarding the degree to which the target system is relevant
to his or her job. Objective
usability: A comparison
of systems based on the actual level (rather than perceptions)
of effort required to complete specific tasks. Output
quality: The degree to which an
individual believes that the system performs his or her job tasks
well.Performance
expectancy: The
degree to which an individual believes that using the system
will help him or her to attain gains in job performance.Perceived
ease of use: See
the definition of effort expectancy.Perceived
enjoyment: The extent to which
the activity of using a specific system is perceived to be enjoyable
in it’s own right, aside from any performance consequences
resulting from system use. Perceived
usefulness: See
the definition of performance expectancy.Perception
of external control: See
the definition of facilitating conditions.Result
demonstrability: Tangibility
of the results of using the innovation. Social
influence: The
degree to which an individual perceives that important others
believe he or she should use the new system.Subjective
norm: Person's
perception that most people who are important to him think he should
or should not perform the behavior in question.Voluntariness: The
