Which type of validity assesses whether a test measures its intended construct?

• A. Criterion validity
• B. Content validity
• C. Construct validity
• D. Face validity

Answer: (C)

Construct validity is crucial for determining whether a test accurately measures the theoretical construct it is intended to assess. This type of validity involves both the empirical and theoretical evaluation of the relationships between the test scores and the outcomes related to that construct. When a test demonstrates strong construct validity, it indicates that the test is effectively capturing the underlying characteristic or concept it aims to measure, including the various facets and dimensions of that construct.

In general, test developers utilize various methods, such as factor analysis and correlational studies, to establish construct validity. This ensures that the test is not only measuring relevant attributes but is also distinct from other constructs, reinforcing its appropriateness and usefulness in psychological or educational assessments. Construct validity thus plays a vital role in helping researchers and practitioners trust the results derived from their assessments.
