What is one way to determine whether a measure is valid?

Criterion-Related Validity

We can think of these outcomes as criteria. We want our measures to properly predict these criteria. To assess criterion-related validity, we correlate our measure with a criterion using the correlation coefficient r. The higher the correlation, the higher the criterion validity.

How do you test for validity?

Validation begins with identifying construct definitions by looking at theories, prior research, observation, and/or analysis of relevant behavior. Test items are then arranged to suit construct definitions. Empirical item analysis occurs when the items that are the most valid are selected from the pool of test items.
