Neurocognitive Variables Underlying Group Performance on a Measure of Effort: The Medical Symptom Validity Test (MSVT)
This study utilized the Medical Symptom Validity Test (MSVT) and a set of standard neuropsychological instruments to determine the underlying construct of the MSVT that accounts for effort in mild traumatic brain injury (mTBI) patients by comparing/contrasting mTBI with dementia and an analog simula...
