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.

Theory/model: Additional to TPB
Reference: (Pavlou & Fygenson, 2006)

Note 2: Some of the indicators are context-dependent.
Note 3: The same construct can be present in more than one theory/model.
