Overview User trust is a measure of whether the user believes the system will act appropriately in a given situation, and can be useful for predicting how the user will interact (or not) with a system. The Test Science team at IDA has developed and is the process of validating one scale for measuring trust in automated systems, The Trust in Automated Systems Test (TOAST[RYS1] [GEA2] ). References for additional scales which are worth considering are also included. Planned future updates to the Validated Scales Repository will expand this section.
