The Integrated Visual and Auditory (IVA) continuous performance test (CPT) is a computer test used to assess attention in individuals with suspected attention difficulties such as Attention Deficit Hyperactivity Disorder (ADHD). It can also be used to monitor the effectiveness of medication.
Like all CPT’s the IVA is designed to be mildly boring but at the same time demanding of sustained attention. The computer tracks performance such as missing targets, responding impulsively to nontargets, reaction time changes, among others. Research studies have shown that the IVA-CPT correctly identifies the presence or absence of ADHD with about 92% accuracy.
When combined with other tools to make a differential diagnosis, the IVA is an important tool in establishing a solid diagnosis of ADHD. Along with direct measures of attention, we use numerous objective tests completed by parents and teachers to determine a proper diagnosis, ruling out such factors as depression and anxiety that may be affecting attention. We also offer psychoeducational testing in order to rule out any learning issues that may be affecting academic performance.
