concurrent validity

— Concurrent validity examines whether a measure is measuring what it intends to measure by exploring its relationship with an established measure, administered at the same time point. 

Full explanation:

Concurrent validity is demonstrated when a new measure highly correlates with a known measure of the concept of interest when both measures are administered at the same time. For example, the Beck Depression Inventory is an established measure of depression. To demonstrate the concurrent validity of a new measure of depression, when administered at the same time point, you would expect scores on the two measures to be highly correlated. Concurrent validity is a form of criterion validity (how well the measure accurately measures the outcome it was designed to measure).
