What is construct validity?

• A. A measure of random chance in testing
• B. A type of reliability assessment
• C. An evaluation of whether a test measures a theoretical construct accurately
• D. A comparison between different test formats

Answer: (C)

Construct validity refers to the degree to which a test accurately measures a theoretical construct or trait that it is intended to measure. This concept is essential in psychological testing and educational assessment because it determines whether the tool being used effectively captures the underlying concept it is purported to measure, such as intelligence, motivation, or anxiety. When testing for construct validity, researchers often use various methods, including correlational studies with other tests (known as convergent and discriminant validity) to see if the test aligns with related constructs and diverges from those that it should not be related to. This thorough evaluation ensures that the test provides meaningful results by aligning with theoretical frameworks that define the construct in question. Other options do not capture the essence of construct validity. For instance, measuring random chance in testing does not reflect the focus on theoretical constructs, while reliability assessment pertains to the consistency of a measure, not its accuracy in measuring constructs. Lastly, comparing different test formats does not address whether a particular test accurately measures its intended construct. Hence, the understanding of construct validity is crucial for establishing the integrity and utility of an assessment tool.
