Which assessment tool includes validity scales such as Malingering, Defensiveness, and Under-Reporting of Substance Abuse?

• A. WAIS
• B. PAI
• C. WISC
• D. SDQ

Answer: (B)

Understanding validity scales is key: they tell you about how the person might be responding, not about their symptoms. The Personality Assessment Inventory includes dedicated validity scales to detect different response styles, including Malingering (faking bad), Defensiveness (downplaying problems), and Under-Reporting of Substance Abuse (not admitting substance use). These scales help clinicians decide whether the test results are trustworthy or if the person might be shaping answers to look better or to avoid disclosure. This is why this option is the best choice: the tool specifically designed with these three validity indicators is the one that includes them. Other instruments listed are focused on intelligence or general behavioral screening and don’t embed these exact validity scales for malingering, defensiveness, or under‑reporting of substance abuse.
