Construct-related validity assesses what aspect of a test?

Construct-related validity is primarily concerned with the extent to which a test accurately measures the theoretical traits or constructs it is intended to measure. This involves demonstrating that the test is not only consistent and reliable but also aligns with the specific attributes that it claims to evaluate. For instance, if a test is designed to measure intelligence, construct-related validity examines whether the test truly captures various dimensions of intelligence as defined by psychological theories.

This aspect of validity is often supported by correlational studies, factor analyses, and comparisons with other established measures of the same construct, thus providing evidence that the test is substantively related to what it purports to assess. This is crucial in ensuring that test scores can be interpreted meaningfully in the context of the constructs they are intended to reflect.
