The most comprehensive type of validity that incorporates a gradual accumulation of evidence is __________ validity.

The most comprehensive type of validity that incorporates a gradual accumulation of evidence is __________ validity.

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

Answer: (B)

Construct validity is about whether the test actually measures the intended theoretical construct and is supported by a growing body of evidence gathered from multiple sources over time. This means looking at how the test’s internal structure fits the construct (factor analysis), how it relates to similar constructs (convergent validity), how it differs from dissimilar ones (discriminant validity), and how well it predicts relevant outcomes. Because validity relies on accumulating diverse evidence across studies and contexts, construct validity naturally becomes more robust as more research accumulates, making it the most comprehensive form. Other types, like content validity (just checking domain coverage), criterion validity (relation to external criteria), and face validity (appearance to test-takers), focus on narrower aspects and don’t integrate evidence as broadly.
