Which statement describes content validity?

• A. Does the test cover the full domain of the construct being measured
• B. Does the test correlate with a gold standard
• C. Does the test yield identical results on retest
• D. Is the test easy to administer

Answer: (A)

Content validity asks whether a test’s items collectively represent all facets of the construct it intends to measure. The best description is that the test covers the full domain of the construct being measured, ensuring that important aspects are included and unrelated items are kept out. This is typically established through expert judgment and by mapping the test items to a content outline or framework of the construct. It differs from other concepts: correlating with a gold standard speaks to criterion validity, a test yielding identical results on retest relates to reliability (stability over time), and how easy the test is to administer concerns practicality rather than validity.
