Detection of malingering in mild traumatic brain injury with the Conners' Continuous Performance Test-II.
Classification accuracy for the detection of malingered neurocognitive dysfunction (MND) in mild traumatic brain injury (TBI) is examined for two selected measures from the Conners' Continuous Performance Test-II (CPT-II) using criterion-groups validation. Individual and joint classification accuracies are presented for Omissions and Hit Reaction Time Standard Error across a range of scores comparing mild TBI malingering (n = 27), mild TBI not-malingering (n = 31), and moderate-to-severe (M/S) TBI not-malingering (n = 24) groups. At cutoffs associated with at least 95% specificity in both mild and M/S TBI, sensitivity to MND in mild TBI was 30% for Omissions, 41% for Hit Reaction Time Standard Error, and 44% using both indicators. These results support the use of the CPT-II as a reliable indicator for the detection of malingering in TBI when used as part of a comprehensive diagnostic system.
