The Relationship Between the Self-Report BASC-2 Validity Indicators and Performance Validity Test Failure After Pediatric Mild Traumatic Brain Injury

Abstract Objective The present study explored both embedded symptom (SVT) and performance (PVT) validity test scores within a post-9/11 veteran sample to elucidate the degree to which there is concordance between validity indicators, as well as how frequently one SVT and four PVT indicators were failed in screened mild traumatic brain injury (mTBI) and diagnosed posttraumatic stress disorder (PTSD). Method A total of 114 post-9/11 veterans were evaluated utilizing the Neurobehavioral Symptom Inventory (NSI) Validity-10, four embedded PVTs, mTBI screening, and a diagnostic interview for PTSD. Results While we found concordance between embedded PVTs and the NSI Validity-10 at select cutoffs (i.e., ≥13, ≥19), symptom and performance validity indicators were clinically dissociable in that only SVT significantly predicted diagnosed PTSD and screened mTBI. Conclusions Dissociation between symptom and performance validity may be clinically useful when interpreting neuropsychological evaluation findings in post-9/11 veterans with a history of mTBI or PTSD.

The Relationship ◽

Serum Bdnf

Brain-derived neurotrophic factor (BDNF) helps restore neuronal function following mild traumatic brain injury. BDNF levels can be obtained in blood serum and more recently in saliva. However, the relationship between serum and salivary BDNF is poorly understood—especially in relation to alterations in BDNF levels following mild traumatic brain injury. In this study, serum and salivary BDNF were collected from a sample of 42 collegiate student athletes. Half of the participants were recently cleared by a physician and/or an athletic trainer to return-to-play after experiencing a sports-related concussion. The other half had not experienced a concussion within the past year and were matched by age, sex, sport, and time of sample. Results suggest that incidences of depression, anxiety, and stress were all elevated in the concussion group, relative to the control participants. When controlling for stress-related negative affect, serum BDNF was elevated in the concussion group. However, there was no difference in salivary BDNF. Serum and salivary BDNF were uncorrelated across the entire sample. Yet, these measures of BDNF were correlated in the concussion group, but not the control group. In sum, serum BDNF is elevated in concussion post return-to-play; however, further research is needed to explore the utility of salivary BDNF following concussion.

The Relationship

Abstract Objective This study aimed to determine the relationship between symptom self-report accuracy and objective cognitive functioning in multiple cognitive domains for varying neurocognitive impairment (NCI) subsequent to Traumatic Brain Injury (TBI). Specifically, the discrepancy between self-report and objective findings among participants with mild, moderate, and severe NCI was examined within the cognitive domains of Attention, Executive Functioning, Learning/Memory, and Speech/Language. Method The sample included archival data consisting of neuropsychological scores and self-reported Ruff Neurobehavioral Inventory (RNBI) results of 135 adult TBI patients with mild, moderate, or severe NCI who received neuropsychological assessment at a private practice. Patients were grouped based on level of impairment using Halstead Impairment Index criteria. Results No main effect was found for Attention. Patients with severe NCI had greater discrepancies in Executive Functioning (p = 0.015), Learning/Memory (p = 0.015), and Speech/Language (p < 0.001) function, when compared to those with mild NCI. Additionally, patients with severe NCI demonstrated greater discrepancies in Speech/Language (p < 0.001) function when compared to those with moderate NCI. Conclusion These findings indicate as severity of neurocognitive impairment increases for TBI patients, self-reported cognitive symptomatology—specifically executive functioning, learning/memory, and speech/language—will become less accurate. Clinically, these findings suggest that when working with patients who have severe neurocognitive deficits subsequent to TBI, it is important to consider objective testing as self-reporting may not be accurate. Understanding patient’s genuine deficits will foster patient awareness and acceptance of TBI-related cognitive deficits with increased investment in treatment and improved neurorehabilitation outcomes.
