Construct validity evaluates what aspect of a test?

Construct validity is integral to assessing whether a test is truly measuring the theoretical concept it claims to measure. This aspect of validity examines the extent to which the test aligns with the underlying theory and constructs it aims to evaluate.

When a test has strong construct validity, it demonstrates that the test items and their outcomes are representative of the theoretical constructs, rather than unrelated variables or aspects. For example, if a test is designed to measure intelligence, construct validity would help ensure that the test is effectively capturing components such as reasoning, problem-solving, and understanding, rather than extraneous factors.

Other aspects such as external factors impacting test results, how participants perceive the relevance of the test, and the efficiency of the test administration process are important for different types of validity or practical considerations but do not directly relate to the evaluation of construct validity. Thus, the focus on whether a test accurately measures the intended theoretical construct is what makes the first choice the correct one.
