Utility of the Personality Assessment Inventory in detecting feigned Attention-Deficit/Hyperactivity Disorder (ADHD): The Feigned Adult ADHD index

Abstract

New validity measures were compared to existing PAI validity indicators and performed better than many of them in this study. The algorithms developed in this study of ADHD simulators and genuine ADHD cases have adequate sensitivity and good specificity and appear to function differently than other PAI symptom validity scales.
