Integrated Visual and Auditory (IVA) Test
The Integrated Visual and Auditory (IVA) Continuous Performance Test (CPT) is a screening tool used in conjunction with other diagnostic procedures (parent and teacher behaviour rating scales, QEEG, TOVA) to assist in the screening of individuals with Attention Deficit Hyperactivity Disorder (ADHD).
The Integrated Visual and Auditory (IVA) Continuous Performance Test (CPT) was developed by John Sandford (psychologist) and Anne Turner (physician). It was designed to discriminate ADHD populations from individuals with Conduct Disorder and without behaviour problems and is based on the research of Chee (1989) and Connors (1994). It can also be used to monitor the effectiveness of neurofeedback/EEG biofeedback training or medication.
The IVA test is a 13 minute computerised test which combines two types of CPTs for both visual and auditory modalities. An objective test like the I.V.A. provides useful data to help clinicians in documenting the presence or absence or response control and attentional problems that support making a clinical, differential diagnosis of ADD/ADHD.
