When selecting an assessment tool, which validity type ensures the tool measures what it intends to measure in this setting?

• A. Face validity.
• B. Content validity and construct validity for the specific context.
• C. Reliability.
• D. Predictive validity.

Answer: (B)

Understanding validity in a specific setting means making sure the tool truly measures the intended construct and covers the right content for that context. Content validity checks that the items span the full domain you want to assess, ensuring important facets aren’t missing. Construct validity shows the instrument actually targets the theoretical construct and behaves as theory predicts, demonstrated through expected relationships with related measures and distinctions from unrelated ones. When these validations are tailored to the setting, you’re confirming the tool is appropriate for how it will be used, not just that it looks like it measures something. While face validity focuses on appearance, it doesn’t guarantee measurement accuracy; predictive validity concerns future outcomes, and reliability is about consistency, not whether the instrument measures the right construct in this context.
