This unique continuous performance test, which combines visual and auditory stimuli, assesses impulsivity, inattention, and hyperactivity in individuals from age 5 through adulthood in just 13 minutes. The client is instructed to click the mouse only when he or she sees or hears a "1" and not to click when he or she sees or hears a "2". Administration and scoring are fully automated, test instructions are presented both visually and aurally by the computer, and results are available immediately to the examiner.
The IVA produces quotient scores for impulsivity and inattention. These identify performances outside the norm. In addition, it gives you a separate scale of fine motor hyperactivity based on impulsive and off-task behavior with the mouse. Twenty-two other scale scores help you pinpoint differences in auditory and visual processing related to impulsivity, attention, focus, stamina, motivation, consistency, speed, and learning problems. Normative information is based on a sample of 781 individuals from 5 to 90 years of age, screened to rule out attention, learning, neurological and psychological problems as well as medication. Norms are separated by sex and age, with about 30 people in each sex/age group, up to age 55.
IVA has demonstrated 92% sensitivity (i.e., an 8% rate of false negatives) and 90% specificity (i.e., a 10% rate of false positives) in differentiating ADHD and normal children. Also, recent research has shown the test 71% accurate in the differential diagnosis of individuals with mild traumatic brain injury from normals (with age and education controlled).Hardware requirements: IBM PC or compatible (386 or higher) with 1 MB RAM (2 MB RAM for portable) and 4 MB hard drive space, DOS 5.0 or higher, graphics monitor (CGA, EGA, VGA), mouse, 3.5" disk drive, Soundblaster Card or 100% compatible card, and headphones or external speakers.
