Abstract Objective Intra-individual variability (IIV) has been associated with cognitive dysfunction and traumatic brain injury (TBI) severity. This study examined IIV in physical medicine and rehabilitation patients grouped by TBI severity and performance validity. Method Participants (N = 213) were 32% female and 90% white with average age and education of 42 (SD = 13) and 14 (SD = 2) years, respectively. Participants completed an outpatient evaluation using a flexible battery of up to 33 common neuropsychological measures. Participants were grouped by TBI severity and validity: mild (32%), moderate (14%), severe (32%), and questionable performance validity (QPV; 22%). QPV was determined on the basis of embedded and freestanding validity measures. Test battery scores were converted to T scores. Cases with four or more scores below 36 T were identified as impaired. Measures of IIV were calculated including overall test battery mean (OTBM), test battery standard deviation (SD), kurtosis, skew, range, and unbiased coefficient of variation (UCV). IIV measures were compared across groups. Results Groups were significantly different in OTBM (p < .001), kurtosis (p < .03), and UCV (p < .001). In valid cases, TBI severity was associated with OTBM (rho = −.31), SD (.19), kurtosis (−.16), and UCV (.33). Impaired and unimpaired cases were significantly different in OTBM (p < .001), SD (p < .001), range (p < .01), and UCV (p < .001). QPV cases were similar to impaired cases on measures of IIV. Conclusions IIV measures have potential clinical utility in characterizing cognitive deficits in TBI and warrant further study.

Abstract Objective Studies on Performance Validity Tests (PVTs) for tele-neuropsychology (TeleNP) are sparse. Verbal PVTs appear to better translate to TeleNP, so the primary objective of this study was to provide initial data on two well-established, verbal PVTs administered via TeleNP for research participants with traumatic brain injury (TBI). Methods This secondary analysis of the Veterans Affairs TBI Model Systems data included 53 participants enrolled in a PVT module study (3/01/2020–09/20/2020) with documented moderate-to-severe TBI per Glasgow Coma Score (M = 6.5, SD = 4.4), posttraumatic amnesia duration (M = 42.7 days, SD = 47.1), and/or time to follow commands (M = 10.5 days, SD = 16.3). Participants completed two PVTs—Reliable Digit Span (RDS) and the 21-Item Test (21-IT)—alongside telephone-based cognitive assessment 1–7 years after TBI. Descriptive analyses were performed to compare PVT performances to previously established cut scores. Chi square analyses were employed to examine 21-IT and RDS as dichotomous outcomes (pass/fail) at selected cutoffs. Results RDS ranged from 5 to 16 (M = 10.5, SD = 2.4). 21-IT ranged from 7 to 21 (M = 16.4, SD = 3.1). For RDS, 9.8% were invalid with a cutscore of ≤7 and 19.6% using a cutscore of ≤8. For the 21-IT, 7.8% were in invalid using a cutscore of ≤11, and 13.7% using a cutscore of ≤12. Conclusion(s) Using previously established cut scores, telephone-administered RDS and 21-IT resulted in relatively low rates of invalid performance among individuals with moderate-to-severe TBI. These findings provide preliminary support for the RDS and 21-IT in TeleNP.

Abstract Objective The number of women veterans seeking Veterans Health Administration services has substantially increased over the past decade. Neuropsychology remains an understudied area in the examination of gender differences. The present study sought to delineate similarities and differences in men and women veterans presenting for neuropsychological evaluation in terms of demographics, referral, medical conditions, effort, and outcome diagnosis. Method A database collected from an outpatient VA neuropsychology clinic from 2013 to 2019 was analyzed (n = 232 women, 2642 men). Additional analyses examined younger (n = 836 men, 155 women) and older (n = 1805 men, 77 women) age cohorts. Results Women veterans were younger and more educated than men, whereas men had higher prevalence of vascular risk factors. Both groups were most often referred from mental health clinics and memory was the most common referral question. Although men performed worse on performance validity measures, clinicians rated women as evidencing poorer effort on a cumulative rating based on formal and embedded performance validity measures, behavioral observations, and inconsistent test patterns. Older women reported more depressive symptoms than older men and were more commonly diagnosed with depression. Conclusions This exploratory study fills a gap in the understanding of gender differences in veterans presenting for neuropsychological evaluations. Findings emphasize consideration for the intersection of gender with demographics, medical factors, effort, and psychological symptoms by VA neuropsychologists. A better understanding of relationships between gender and these factors may inform neuropsychologists’ test selection, interpretation of behavioral observations, and diagnostic considerations to best treat women veterans.
