Symptom Validity Test

Abstract Objective The purpose of this study was to evaluate the presence of demographic, injury and neuropsychological correlates of distinct patterns of performance validity test and symptom validity test results in persons with mild traumatic brain injury (mTBI). Method One hundred and seventy-eight persons with mTBI completed the Test of Memory Malingering (TOMM; performance validity) and the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF; symptom validity) within 1–12 months postinjury. Four groups were compared: (a) pass both TOMM and MMPI-2-RF validity criteria, (b) pass TOMM and fail MMPI-2-RF, (c) fail TOMM and pass MMPI-2-RF, and (d) fail both TOMM and MMPI-2-RF. Results Compared to Group a, participants in combined Groups b–d were more than twice as likely to be engaged in financial compensation-seeking and about four times less likely to have neuroimaging evidence of an intracranial lesion. The average performance of Group d on an independent test of verbal learning was more than 1.5 standard deviations below that of Group a. Participants in Group b were more likely to have intracranial lesions on neuroimaging than participants in Group c. Conclusion Performance and symptom validity tests provide complementary and non-redundant information in persons with mTBI. Whereas financial compensation-seeking is associated with increased risk of failure of either PVT or SVT, or both, the presence of intracranial findings on neuroimaging is associated with decreased risk of such.

Abstract Objective: This study aimed to examine the predictors of cognitive performance in patients with pediatric mild traumatic brain injury (pmTBI) and to determine whether group differences in cognitive performance on a computerized test battery could be observed between pmTBI patients and healthy controls (HC) in the sub-acute (SA) and the early chronic (EC) phases of injury. Method: 203 pmTBI patients recruited from emergency settings and 159 age- and sex-matched HC aged 8–18 rated their ongoing post-concussive symptoms (PCS) on the Post-Concussion Symptom Inventory and completed the Cogstate brief battery in the SA (1–11 days) phase of injury. A subset (156 pmTBI patients; 144 HC) completed testing in the EC (∼4 months) phase. Results: Within the SA phase, a group difference was only observed for the visual learning task (One-Card Learning), with pmTBI patients being less accurate relative to HC. Follow-up analyses indicated higher ongoing PCS and higher 5P clinical risk scores were significant predictors of lower One-Card Learning accuracy within SA phase, while premorbid variables (estimates of intellectual functioning, parental education, and presence of learning disabilities or attention-deficit/hyperactivity disorder) were not. Conclusions: The absence of group differences at EC phase is supportive of cognitive recovery by 4 months post-injury. While the severity of ongoing PCS and the 5P score were better overall predictors of cognitive performance on the Cogstate at SA relative to premorbid variables, the full regression model explained only 4.1% of the variance, highlighting the need for future work on predictors of cognitive outcomes.
