Due to increased concern about malingered self-report of symptoms of attention-deficit/hyperactivity disorder (ADHD) in college students, there is a need for instruments that can detect feigning. The present study provided further validation data for a recently developed validity scale for the Conners’ Adult ADHD Rating Scale (CAARS), the CAARS Infrequency Index (CII). The sample consisted of 139 undergraduate students; 21 individuals with diagnoses of ADHD, 29 individuals responding honestly, 54 individuals responding randomly (full or half), and 35 individuals assigned to malinger. The CII demonstrated modest sensitivity to malingering (.31-.46) and excellent specificity to ADHD (.91-.95). Sequential application of validity scales had correct classification rates of honest (93.1%), ADHD (81.0%), malingering (57.1%), half random (42.3%), and full random (92.9%).
