ADHDtesting.org, A real look at TOVA (test of variables in attention) and ADD/ADHD

This testing method is a 21.6 minute computerized Continuous Performance Test (CPT) with claims that professionals can use it to “diagnose as well as monitor treatment of ADD/ADHD in children and adults.” Ablechild has recently been receiving reports that parents are being told by certain “professionals” that there is a test that will tell if their child has this diagnosis. They describe it as a flashing or blinking light on a computer screen. This test we know to be the TOVA.

"A computerized test that requires no use of language, no right-left discrimination, nor recognition of letters or numerals. Rather, the two visual stimuli are a large box containing a smaller box that is adjacent to the top or bottom edge of the larger box (see example). The stimulus of the inner box adjacent to the top edge is the designated target. The T.O.V.A. presents two 11-minute test conditions that involve frequent and infrequent presentation of targets".

Example of target and non-target stimuli for the T.O.V.A.

To be simply put, one is labeled ADHD by being too slow on where the image is - top, bottom, left or right sides.

FACT: There is NO valid test for ADD/ADHD. The TOVA is not exempt from this statement. The TOVA is not a valid test and does not prove that a child has ADD/ADHD.

The TOVA is the latest trendy and popular gimmick testing method that is being misrepresented to parents worldwide. When looking into this we have discovered websites selling an at home version “Do it yourself Diagnosis Using the Home TOVA.” Many of these sites claim this version isn’t as “accurate” as a clinical version TOVA, but is much more cost conducive for parents. What is important to know here is that the term “accurate” clearly misleads the person that reads these claims, by implying that the TOVA itself is an accurate testing method to determine the diagnosis ADD/ADHD.

Buyer Beware! Terms are important and claims that “it is an accurate indicator of ADD/ADHD” are just not ACCURATE!

If you are one of the ones that have been told that the TOVA will tell you that your child has ADD/ADHD always remember this:

FACT: The TOVA has been determined to be unreliable as an indicator of ADD/ADHD. No State or Local Government, or Federal Government Agency (NIH, CDC, FDA, DHE&W) has approved, certified, authenticated or validated this test as being able to determine the presence of ADD/ADHD in life or at autopsy. Nor has the test Manufacturer provided us with a US Government Certificate of Compliance proving the tests validity and or acceptance.

This is what someone in the computer field had to add about the TOVA as well, proving more inconsistencies and further invalidating it as a “testing” method:

“I spent 25 years in the computer field and I know everyone's keyboard and CPU and monitor all offer different "response" times so if any of those response times VARY the end TEST results furnished by TOVA will include that variance and that will skew the over-all results. TOVA doesn't tell the end user this and ALL children's TOVA test results are based on the Child’s RESPONSE TO the questions asked by the computer. This makes any accuracy "variable" and hardware dependent.”

Are parents informed of this potential for inaccuracy? More importantly are the parents INFORMED OF THIS IN ADVANCE TO CHILD TESTING?
