Which validity type compares results with another instrument whose validity has been previously established?

• A. Concurrent Validity
• B. Internal Consistency
• C. Content Validity
• D. Predictive Validity

Answer: (A)

This question is about how validity is established by comparing a new measure to an already validated standard. Concurrent validity is a form of criterion-related validity where the new instrument is tested against a criterion that has already been shown to be valid, and both measures are collected at roughly the same time. A strong correlation between the two instruments indicates that the new test is measuring the same construct as the established one. For example, a new preschool screening tool would be given at the same time as a well-validated developmental assessment; if its results align with the established tool, that supports concurrent validity. Internal consistency looks at how well the items on a single test hang together, not how the test compares to another instrument. Content validity concerns whether the test covers the full domain of the skill or knowledge area. Predictive validity is about how well the test forecast future performance or outcomes.
