ISRI - Information Systems Research Indicators

Construct: Efficacy

Description
Indicators

Note 1: Following are presented the definitions found for the construct in the used references, together with the theory/model.
Note 2: The same construct can be present in more than one theory/model.
Note 3: If the construct was not proposed in the original theory/model, it is identified as "Additional to theory/model".

Definition: An individual's self-confidence in his/her ability to perform a behavior.

Theory/model: DTPB
Reference: (Taylor & Todd, 1995b)

Note 1: This list contains all the indicators (measuring variables) as defined by the authors when proposing/using/applying a theory/model in a context. It also includes the scales used to measure the variables.
Note 2: Some of the indicators are context-dependent.
Note 3: The same construct can be present in more than one theory/model.

Indicator	Scale	Context	Theory/Model	Reference(s)
I would feel comfortable using the CRC on my own.	Scale 0 to 7	Computing Resource Center (CRC)	DTPB	(Taylor & Todd, 1995c)

For me, feeling comfortable using a service on my own is: (unimportant/important).	Scale 0 to 7	Computing Resource Center (CRC)	DTPB	(Taylor & Todd, 1995c)

If I wanted to, I could easily operate any of the equipment in the CRC on my own.	Scale 0 to 7	Computing Resource Center (CRC)	DTPB	(Taylor & Todd, 1995c)

For me, being able to easily operate equipment on my own is: (unimportant/important).	Scale 0 to 7	Computing Resource Center (CRC)	DTPB	(Taylor & Todd, 1995c)

I would be able to use the equipment in the CRC even if there was no one around to show me how to use it.	Scale 0 to 7	Computing Resource Center (CRC)	DTPB	(Taylor & Todd, 1995c)

For me, being able to use equipment even if there is no one around to show me how to use it is: (unimportant/important).	Scale 0 to 7	Computing Resource Center (CRC)	DTPB	(Taylor & Todd, 1995c)

If I wanted to, I could easily operate a VCR-Plus+TM on my own: (unlikely/likely).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)

Being able to operate a product on my own is: (unimportant/important).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)

I know enough to buy a VCR-Plus+TM on my own: (unlikely/likely).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)

Knowing enough to buy a product is: (unimportant/ important).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)

I would feel comfortable buying a VCRPlus+TM on my own: (unlikely/likely).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)

Being comfortable buying a product on my own is: (unimportant/important).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)

I would be able to use the VCR-Plus+TM even if there is no one around to tell me how to use it: (unlikely/likely).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)

Being able to use a product even if no one is around to tell me how to use it is: (unimportant/important).	Scale -3 to +3	VCR Plus and TM	DTPB	(Taylor & Todd, 1995b)
