Twelve Key Features of the MeSA
- Comprehensive multi-study research-based norms corrected for the person’s exact age and education level – Click here for MeSA-AE norms and here for MeSA-IE.
- Integration of MeSA and IVA-2 test results in IVA-2 reports – Click here.
- Step-by-step guidance in providing easy-to-learn standardized test administration steps.
- Less judgmental non-verbal corrective feedback (i.e., a buzzer).
- Computerized timing and error scoring.
- Standardized scoring for easy comparison to IVA-2 and IQ test results – Click here.
- Research based guidance for assessing the possibility of malingering.
- The ability to differentiate in a relevant clinical way the different cognitive skills assessed by Test A (Attention Control) and Test B (Cognitive Flexibility) rather than using idiosyncratic ratio or difference scores based on raw test completion times – Click here.
- A normative research-based standard score of overall test performance which is based on the combined time of Test A and B (Executive Control) – Click here.
- The availability of alternative equivalent test forms for retesting.
- Standard and in-depth clinical interpretative reports that can be easily customized.
- Freedom to administer MeSA tests at multiple locations using an iPad.
The IVA-2 is a test of attention like all CPTs. The fact that the IVA-2 was found to significantly correlate with both QEEG and fMRI measures of attention provides validation that it truly measures what it was designed to measure (i.e., attentional functioning). Both QEEG and fMRI measures of attention have been found in various research studies to be useful in identifying individuals with ADHD and differentiating them with clinical efficacy.In light of the value of QEEG, the FDA approved a new QEEG based test last year after determining that it had sufficient clinical accuracy to be medically appropriate for use in helping clinicians in their diagnostic process when evaluating ADHD symptoms. This test was based in part of the research completed over 15 years ago by Dr. Joel Lubar and Dr. Vince Monastra, who identified the clinical sensitivity of QEEG analysis in classifying individuals with ADHD.
Thus, the IVA-2 test’s validity as a useful tool in the diagnostic process of clinicians is partly based on the fact that it is an accurate measure of the underlying psychophysiological processes of attention confirmed by independently completed research studies.
