ISRI - Information Systems Research Indicators

Construct: Disconfirmation

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: Not defined.

Theory/model: Additional to TAM
Reference: (Bhattacherjee & Lin, 2015)

Definition: The extent to which subjects’ preusage expectation of technology usage is contravened during actual usage experience

Theory/model: Additional to TTF
Reference: (Sun & Fang, 2016)

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.
