Theory constructs and annotations

• Behavioural intention A self-conscious plan to engage or not engage in a given behaviour [ BCIO:006016 (Behavioural intention) 73 , BCIO:050228 (Mental plan) 73 1 66 14 59 46 72 23 77 69 52 81 74 79 80 3 24 18 ]
• Use behaviour The extent to which one uses available systems [ BCIO:036027 (Object-using behaviour) 73 ]
• Perceived ease of use Beliefs about the level of effort required to use the technology [ BCIO:050589 (belief about effort required for a behaviour) 73 ]
• Perceived usefulness Beliefs about whether or not using the technology will enhance one’s performance [ BCIO:050648 (Evaluative belief about the positive consequences of a behaviour) 73 28 57 32 60 78 16 3 ]
• Objective usability A comparison of systems based on actual [as opposed to perceived] amount of effort needed to perform a task [ BCIO:006086 (Behavioural opportunity) 73 25 1 32 11 4 60 67 65 59 8 74 66 41 5 77 56 9 12 79 ]
• Computer self-efficacy One’s perception of whether one is capable of performing a task using the technology [ BCIO:006154 (Self-efficacy belief for a behaviour) 73 56 54 66 14 60 81 82 16 17 4 57 42 80 78 ]
• Perception of external control Beliefs about whether external resources are available to support the behaviour [ BCIO:050591 (Belief about enablers of a behaviour) 73 79 72 ]
• Computer anxiety The level of apprehension or fear felt when faced with the possibility of using technology [ BCIO:050566 (Anxiety about use of technology) 73 ]
• Computer playfulness The level of cognitive spontaneity in interactions with technology; represents the intrinsic motivation associated with using any new system [ BCIO:006136 (Intrinsic motivation) 73 56 ]
• Perceived enjoyment The extent to which engaging in a behaviour is perceived as enjoyable in its own right, regardless of external consequences [ BCIO:050606 (Belief about the positive emotional consequences of a behaviour) 73 ]
• Image The degree to which use of an innovation is perceived to enhance one's status among one's social group and influences [ BCIO:050608 (Belief about the positive social consequences of a behaviour) 73 ]
• Job relevance The perception of how applicable a technology is to one’s job [ MF:0000041 (Belief) 73 72 33 34 1 14 28 30 31 35 42 54 67 79 ]
• Result demonstrability The extent to which the results of using the technology are tangible, allowing for the attribution of improved job performance to technology use [ BCIO:050661 (Feedback on behaviour) 73 ]
• Output quality The perception of how well a technology performs job-relevant tasks [ MF:0000041 (Belief) 73 72 33 34 1 14 28 30 31 35 42 54 67 79 ]
• Subjective norm One’s perception of important others' beliefs about whether or not one should perform the behaviour [ BCIO:006042 (Normative belief) 73 79 35 81 1 3 14 ]
• Experience The extent to which one has previous experience with the system
• Voluntariness The extent to which one perceives the behaviour to be mandatory [ BCIO:050609 (Belief that a behaviour is compulsory) 73 ]
• Adjustments Alterations in judgements following hands-on experience with the new system [ MF:0000006 (Judging) 73 ]
• Anchors General beliefs about technology and technology use [ MF:0000041 (Belief) 73 72 33 34 1 14 28 30 31 35 42 54 67 79 ]
