Feedback:
Construct validity, an instrument's adequacy in measuring the targeted construct, is a hypothesis-testing endeavor. Content validity concerns the sampling adequacy of the content being measured. Expert ratings on the relevance of items can be used to compute a content validity index (CVI). Criterion-related validity (which includes both predictive validity and concurrent validity) focuses on the correlation between an instrument and an outside criterion.
