IQ Test Profiles Frequently Associated with ADHD

Intelligence Test (Author) / ADHD Profile (Study Notes/Authors)
Differential Ability Scales (DAS; Elliott, 1990) / Relative to normal controls, low scores on the Sequential and Quantitative Reasoning, and Recall of Digits subtests (Note: subjects, 63% combined type; Gibney, McIntosh, Dean, & Dunham, 2002).
Cognitive Assessment System (CAS; Naglieri & Das, 1997) / Relative to general education students, significantly lower Planning Scale scores (Note: subjects, students referred for ADHD evaluation; Naglieri, Salter, & Edwards, 2004).
Kaufman Assessment Battery for Children (KABC-II; Kaufman & Kaufman, 2004) / Relative weakness on the Hand Movements subtest (Note: test used, KABC; Barkley, 2006).
Stanford-Binet Intelligence Scale-Fifth Edition (SB-V; Roid, 2003) / Relative to normal controls, significantly lower Working Memory factor scores (Note: subjects, combined type; Blashko, 2006).
Universal Nonverbal Intelligence Test (UNIT; Bracken & McCallum, 1998) / Memory Quotient score on average 10 points lower than Reasoning Quotient score (Pendley, Myers, & Brown, 2004).
Wechsler Intelligence Scale for Children (WISC-IV; Wechsler, 2003) / Relative to Full Scale IQ, 84% have significant Processing Speed + Freedom from Distractibility weakness (Notes: subjects, inattentive subtype; test used, WISC III; Calhoun & Mayes, 2005).
Woodcock-Johnson Test of Cognitive Abilities (WJ-III Cog; Woodcock, McGrew, & Mather, 2001) / Relative to children without ADHD, significantly lower Processing Speed scores (Note: subjects, all but one combined type; Penny, Waschbusch, Carrey, & Drabman, 2005).
