Table 2 Measures of validity and their definitions for simulation-models

From: Systematic review of three-dimensional printing for simulation training of interventional radiology trainees

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
