Which statement best reflects the relationship between content validity and construct validity?

• A. Content validity assesses domain coverage; construct validity assesses the theoretical relationships between constructs.
• B. They are the same concept.
• C. Content validity ensures reliability.
• D. Construct validity ensures timing.

Answer: (A)

The main idea here is distinguishing what each type of validity is checking. Content validity is about domain coverage: do the items in the measure represent all facets of the construct we intend to assess? It’s usually judged by experts who map items to the different dimensions of the construct to ensure nothing important is left out. Construct validity is about how the measure fits the theory: do the results relate to other variables and constructs in ways the theory predicts, and do the internal relationships among items reflect the expected structure (for example, through construct- or factor-based relationships, convergent and discriminant validity).

That’s why the best choice says content validity assesses domain coverage and construct validity assesses the theoretical relationships between constructs. The other statements miss the essential distinction: they imply the two are the same, or tie content validity to reliability, or attach timing to construct validity, which isn’t what these concepts address.
