A Scale to Evaluate Trust in Industrial Human-Robot Collaboration
This is the most up-to-date version of this scale.
Construct Summary
The authors aim to measure trust specifically in the context of industrial human-robot collaboration (HRC). They identify two main factors - robot performance and robot’s physical attributes - that play a role in trust in industrial HRC contexts.
Rating = 85%
| 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? |

Final Scale Items (10 total):
The way the robot moved made me uncomfortable
The speed at which the gripper picked up and released the components made me uneasy
I trusted that the robot was safe to cooperate with
I was comfortable the robot would not hurt me
The size of the robot did not intimidate me
I felt safe interacting with the robot
I knew the gripper would not drop the components
The robot gripper did not look reliable
The gripper seemed like it could be trusted
I felt I could rely on the robot to do what it was supposed to do
