Construct validity addresses the question of whether the measure accurately reflects the underlying construct or concept being studied. This requires clear and well-defined conceptual boundaries, which is the most basic form of measurement validity. Discriminant validity is concerned with whether the measure is able to distinguish between the construct being studied and other constructs, while convergent validity is concerned with whether different measures of the same construct are related. Criterion validity is concerned with whether the measure is able to predict some external criterion, such as a behavior or outcome. None of these fully address whether the measure accurately reflects the construct being studied, which is the focus of construct validity.
