What is T.O.V.A?

T.O.V.A
(Test of Variables of Attention)

The Tests of Variables of Attention, T.O.V.A., is an objective, standardized and highly accurate continuous performance test, (CPT) that is used to assess attention. It is a non-language based, sufficiency long computerized test that require no left-right discrimination or sequencing and have no appreciable practice effects. Responses are recorded with the specially design, highly accurate (+/- 1msec) electronic Micro-switch.

An initial interview is required to investigate the background of the client, to make sure if a T.O.V.A would cement understandings for the client. Medical and other reports, e.g. school, life behaviors are taken into account. The T.O.V.A is individually administered. The client is to sit for 21.6 minutes, facing a screen and is to trigger for the target, (or ignore the non-target), depending on which is displayed at one time.

T.O.V.A
• Assess attention in neuropsychological and neuropsychiatric evaluations.
• Screen for disorders of attention, (ADD, AHDH, Processing problems).
• Key components in the diagnosis of disorders of attention.
• Measure medication response.
• Titrate dosage of medication if needed.
• Monitor treatment over time.

T.O.V.A is designed to measure attention and impulse control separately. This is important, as behavioral rating scales can only subjectively rate behaviors correlative to attention but cannot objectively measure attention. Behavioral ratings scales can rate impulse control, but they cannot measure impulse control in relationship to attention processing due to their design.
