Which validity type concerns whether a measure covers the full range of dimensions of a concept?

• A. Content validity
• B. Face validity
• C. Criterion validity
• D. Measurement validity

Answer: (A)

Content validity is about whether a measure includes items that represent all the relevant facets of the concept being measured. If any important dimensions are missing, the instrument may fail to capture the full construct, limiting its usefulness for drawing accurate conclusions. Experts map the domain of the concept and evaluate whether each key dimension is covered by the items, ensuring the measure is comprehensive. Face validity looks at whether the measure appears to assess the right thing on the surface, which can be misleading about actual coverage. Criterion validity asks how well the measure relates to external standards or outcomes. The term measurement validity is not specific enough to describe coverage of a construct’s dimensions.
