The IVA-QS Continuous Performance Test (CPT) is a psychological screening test for assessing visual and auditory attention and impulse control. It is designed to help health professionals in their evaluation of attention and general cognitive functioning. The use of the IVA-QS requires that it be administered in accordance with the specified test guidelines under the supervision of a qualified licensed health care professional. The test by itself is not to be used as a stand-alone instrument in making a diagnosis, but provides data that can be helpful to clinicians as part of their comprehensive evaluation.
