Construct Summary

The authors define trust in automation as:

“the attitude of a user to be willing to be vulnerable to the actions of an automated system based on the expectation that it will perform a particular action important to the user, irrespective of the ability to monitor or to intervene.” (p. 4)

Check? Guideline Item
✓ Is the construct defined?
✖ Does the final version of the items capture the construct as it has been defined by the authors?
✓ Is the item generation process discussed (e.g., literature review, Delphi method, crowd-sourcing)?
✖ Person to items 10:1 for the initial set of items?
✓ Did they perform an EFA, PCA, Rasch, or similar test to determine the item to factor relationship?
✓ Did they describe how they determined number of factors?
✖ Did they report the full initial set of items?
✓ Did they provide loadings (EFA) or item fits (Rasch) of all items?
✓ Is there a description of the item removal process (e.g., using infit/outfit, factor loading minimum value, or cross-loading values)?
✖ Did they list the final items included in the scale?
✖ Did they include a factor structure test (e.g., second EFA, CFA, DIF, test for unidimensionality when using Rasch, or similar)?
✓ Was a measure of reliability (e.g., Cronbach’s alpha, McDonalds Omega_h or Omega_t, Tarkkonen’s Rho) reported?
✓ Was a test of validity (e.g., predictive, concurrent, convergent, discriminant) reported?

Comments The authors added two items after the whole analysis. Therefore, checks given for item and scale development guideline criteria does not include these additional items.
