The MSI-R includes how many validity scores?

• A. One
• B. Three
• C. Two
• D. None

Answer: (C)

Understanding validity scores in assessment means recognizing checks built into the test to protect you from drawing conclusions based on biased or faulty responding. The MSI-R has two validity scores, designed to catch two different kinds of response patterns. One indicator flags unlikely or random responding, helping you spot carelessness or inconsistent answering. The other indicator looks for defensiveness or impression management, catching attempts to present oneself in a more favorable light. Together, these two validity scores give a quick sense of data quality and help determine how much weight to place on the rest of the profile. Choices suggesting a single validity score, three, or none don’t fit because this instrument specifically includes two distinct validity indicators.
