Criterion validity is the degree to which the scores of a PRO measure are an adequate reflection of a “gold standard.” There are two types of criterion validity: (1) Concurrent validity is demonstrated when the outcomes of the instrument are highly correlated with those of the criterion. (2) Predictive validity is demonstrated when the outcomes of the instrument are highly correlated with those of the criterion that can only be assessed at some point in the future (i.e. after the instrument has been administered). The criterion validity is only as good as the validity of the gold standard being compared against.
