Testing for ADHD
The Test of Variables of Attention (T.O.V.A.®)
An FDA-cleared, computerized, and objective measure of attention and inhibitory control normed by gender for ages 4 to 80+.
ABOUT THE T.O.V.A.
The T.O.V.A. provides healthcare professionals with objective measurements of attention and inhibitory control. The visual T.O.V.A. aids in the assessment of, and evaluation of treatment for, attention deficits, including attention-deficit/hyperactivity disorder (ADHD). The auditory T.O.V.A. aids in the assessment of attention deficits, including ADHD. T.O.V.A. results should only be interpreted by qualified professionals.
The T.O.V.A. is a culture- and language-free, sufficiently long computerized test that requires no left/right discrimination or sequencing. Responses to visual or auditory stimuli are recorded with a unique, highly accurate (±1 ms) microswitch. The T.O.V.A. calculates response time variability (consistency), the response time (speed), commissions (impulsivity), and omissions (focus and vigilance). These calculations are then compared to a large age- and gender-matched normative sample, as well as to a sample population of individuals independently diagnosed with ADHD. These comparison results are used to create an immediately available, easy-to-read report.
The T.O.V.A. provides information that is not available through self-report or the report of others. It is used along with a clinical interview and subjective measures (such as behavior ratings) for a more comprehensive picture of academic, social, and personal performance and impairment. T.O.V.A. results should only be interpreted by qualified healthcare professionals.
