Can someone suggest me any research/study on using the Kaufman Brief Intelligence Test to assess Trauma Brian Injury (TBI)? And particularly, is the unusual large discrepancy between verbal and non-verbal scores in K-BIT indicative of TBI? or does it just raised concerns about general cognitive abilities that need further assessment? Thanks
Titel: Validity of the Kaufman Brief Intelligence Test (K-BIT) in children with traumatic brain injury

Relatively, it is good specificity per se but sensitivity is poor, specially in child age groups.
The Kaufman Brief Intelligence Test is part of the brief intelligence tests that are useful in a screening process. Only serves to estimate overall level of intellectual Functioning in conditions similar to those used in the validation, and the test performance may signal the need for a thorough assessment with neuropsychological measures
We can´t interpret the unusual large discrepancy between verbal and non-verbal scores in K-BIT as indicative of TBI, because the test validity do not provide sufficient evidence for diagnosis, and the estimation of these discrepancies in a short test can lead to an increase in estimation error. You can find people without TBI are presenting large discrepancies or people with TBI who has no.
In these cases, I recommend to do a complete neuropsychological assessment, regardless of whether there is discrepancy between verbal and non-verbal scores.
