The degree to which a measure actually assesses what it claims to assess.

Validity is about whether the test scores support the claim about what the test is supposed to measure. The statement describes the degree to which a measure actually assesses the intended construct, which is construct validity. This means the instrument should align with the theoretical concept it’s meant to capture: evidence would include the test correlating with other measures of the same construct (convergent validity), showing weaker or appropriate relationships with unrelated constructs (discriminant validity), and a factor structure that matches the construct’s theoretical components.

Content validity, by contrast, focuses on whether the items cover all relevant aspects of the domain, not on whether the scores reflect the underlying construct as theory predicts. Consequential validity concerns the outcomes or implications of using the test. So the statement best describes construct validity because it targets whether the measure truly measures the intended construct rather than just covering content or producing acceptable consequences.
