Measures of validity and their definitions for simulation-models

Type of Validity	Definition
Face validity	Measures the extent that the simulation represents its real-life model
Content validity	Measures the ability for the model to meet its training objectives
Concurrent validity	Compares the model to gold standards in ability to measure the same behaviors
Discriminant validity	Discerns the ability for a model to produce results different from another validated test (if it is intended to do so)
Predictive validity	Evaluates if the simulator accurately or positively correlates with performance in a non-simulated environment
