Who Are the Invalids on Continuous Performance Tests?
O'Laughlin, Elizabeth M.; Cerny, Jerome A.; Kirby, Edward A.
The percent and characteristics of children who produced invalid profiles on two different continuous performance tests (CPTs) tasks were examined. Sixty-one children referred for attention deficit hyperactivity disorder (ADHD) assessment and 24 non-clinical control children (all children ages 5-16) were given the Test of Variables of Attention (TOVA) and the Intermediate Visual and Auditory Continuous Performance Test (IVA) as part of a larger assessment battery. Results revealed that 19 percent of all subjects produced an invalid profile on the TOVA and 24 percent of subjects yielded an invalid profile on the visual and/or auditory scales on the IVA. The majority of invalid profiles on the IVA were produced by children diagnosed with ADHD. On the TOVA, a similar number of ADHD and control children produced invalid results in the second half of the test due to excessive anticipatory errors. Children under the age of 7 and those with an estimated IQ of less than 85 were more likely to produce invalid profiles on the IVA. Results suggest that a significant number of children referred for ADHD assessment are likely to produce invalid scales on these two commonly used CPT measures, indicating that CPT manuals and research should address this problem.
