Neuroimaging as a biomarker in symptom validity and performance validity testing

Abstract: How neuropsychological assessment findings are deemed valid has been a topic of numerous articles but few have addressed any role that neuroimaging studies could provide. Within military and various clinical samples of individuals undergoing neuropsychological evaluations, high levels of failure on measures of symptom validity testing (SVT) and/or performance validity testing (PVT) have been reported. Where 'failure' is defined as a below cut-score performance on some pre-determined set-point on a SVT/PVT meas… Show more

“…The current state of human brain imaging has just started to use this type of research to identify potential biomarkers for psychiatric illnesses. For instance, one could use brain imaging to test symptom or performance validity (Bigler, ). Accurate modeling of relationships between brain function and behavior is key in this effort but needs much more work (Rigoux & Daunizeau, ).…”

“…Especially, concerns have been raised about the potential influence of apathy on PVTs. An apathetic patient may not be able to invest sufficient effort into testing, and consequently be wrongfully classified by the PVT as noncredible (Bigler, 2015).…”

“…The above statement indicates an inability of the ImPACT test to consistently align healthy asymptomatic patients with no cognitive impairments (and vice versa) and suggests that the ImPACT test results likely must be considered in terms of physiological impairments (Talavage et al ., ; Fox, ; Iverson et al ., ; Kontos et al ., ; Bigler, ). Moreover, there are other concussion management practices which rely on balance testing pre‐ and post‐injury (Guskiewicz, ).…”
