Criterion validity

In psychometrics, criterion validity is a measure of how well one variable or set of variables predicts an outcome based on information from other variables, and will be achieved if a set of measures from a personality test relate to a behavioral criterion on which psychologists agree.[1] A typical way to achieve this is the extent to which a score on a personality test can predict future performance or behavior. Another way involves correlating test scores with another established test that also measures the same personality characteristic.[1]

Criterion or concrete validity is the extent to which the measures are demonstrably related to concrete criteria in the "real" world. This type of validity is often divided into "concurrent" and "predictive" sub-types of validity. The term "concurrent validity" is reserved for demonstrations relating a measure to other concrete criteria assessed simultaneously. In Standards for Educational & Psychological Tests, it states, "concurrent validity reflects only the status quo at a particular time." Although concurrent and predictive validity is similar, it is cautioned to keep the terms and findings separated. "Concurrent validity should not be used as a substitute for predictive validity without an appropriate supporting rationale." [2] "Predictive validity" refers to the degree to which any measure can predict future or independent past events.
