Validity, Concurrent

Concurrent validity is a logical inference from which results of a new measure or test share comparable results as some other previously validated measure or test. The type of validity testing belongs to the category of criterion validity, which more or less accurately predicts the same outcome as a previously validated measure or test. The extent to which new test results correspond with results from a previously validated measure is the extent to which concurrent validity may be argued. The higher the degree of similarity in function (e.g., high correlation) between the two tests—one new and one previously validated—the more concurrent validity becomes established. Concurrent validity, therefore, is the simultaneous accuracy of measurement evidenced by comparison with results from a previously validated test.
