An investigator has developed a new assay to detect precance

An investigator has developed a new assay to detect precancerous lesions of the eyeball. The new test is much less expensive and can be done during a simple eye exam while the older, gold standard test requires that a small scraping from the eyeball be taken. By comparing the new assay to the gold standard, what is the investigator assessing?

Select one:

Criterion-related validity

Content validity

Stability

Equivalency

Internal consistency

Construct validity

Solution

Comparing the test with an established measure is known as criterion related valitidy. Thus, here the investigator should choose criterion related validity.
