Concurrent validity in testing


Concurrent validity is a method of test score validity based on the correlation of two sets of scores obtained at the same time.

Example: A clinician creates a test of anger and hands the test to patients for completion. High scores represent high levels of anger. A different clinician rates the level of anger in the same patients based on interviews and rates the level on a scale of 1-10. Each patient has two sets of anger scores. A researcher can calculate the correlation between the test and the ratings. If the correlation is moderately high and not likely due to chance, then there is evidence for concurrent validity when using the new test under similar situations.
