Construct validity is the degree to which a measure accurately assesses the theoretical construct it is intended to measure. It asks whether the operational measure represents the intended concept rather than a related or unintended phenomenon. section 6.3.2 section 6.4
Assess construct validity after establishing that measures are reliable, and use it to support meaningful, trustworthy results for stakeholder decisions. Distinguish it from content or face validity, which examines coverage of a concept, and criterion validity, which examines association with similar measures. section 6.3.2 section 6.4
Use these questions when evaluating a measure:
- Does the measure correspond to the theoretical construct it claims to represent? section 6.3.2
- Does it produce results that reflect the phenomenon being investigated and justify stakeholder confidence? section 6.4
