RESUMEN
INTRODUCTION/OBJECTIVE: To describe level of awareness, as assessed by the Mayo-Portland Adaptability Inventory-4 (MPAI-4), across physical, cognitive, functional, and emotional domains in individuals with mild, moderate, and severe traumatic brain injury (TBI) participating in a residential rehabilitation program. In addition, this study aimed to examine the relationship between time since injury and awareness. A novel way the MPAI-4 can be used to measure self-awareness is also presented. METHOD: Retrospective analysis of existing data. The MPAI-4 was completed by the patient on admission, as well as by provider consensus within 2 weeks of admission. Level of awareness was determined by discrepancy scores, computed as MPAI-4 provider consensus score minus self-report MPAI-4 score, for the total score and for each index score: Ability, Adjustment, and Participation. PARTICIPANTS: A total of 101 military veterans and active duty service members admitted to a Veterans Affairs community reintegration rehabilitation program. RESULTS: Discrepancies between patient and provider reports of functioning were found among all severities of TBI across the MPAI-4 total score and index domains measuring Ability, Adjustment, and Participation. Interestingly, those with mild TBI endorsed greater impairments than their providers, while those with moderate and severe TBI reported less impairment on the MPAI-4 than providers. The effect of time varied across domains, and those who were more than 1 year postinjury displayed greater self-awareness. CONCLUSION: This study highlights the importance of measuring awareness of functional ability over time and across TBI severity and introduces a novel method for doing so, using the MPAI-4 for comparison between staff and patient reports.

BACKGROUND: Individuals with bipolar disorder often endorse dysfunctional beliefs consistent with cognitive models of bipolar disorder (Beck, 1976; Mansell, 2007). AIMS: The present study sought to assess whether young adult offspring of those with bipolar disorder would also endorse these beliefs, independent of their own mood episode history. METHOD: Participants (N = 89) were young adult college students with a parent with bipolar disorder (n = 27), major depressive disorder (MDD; n = 30), or no mood disorder (n = 32). Semi-structured interviews of the offspring were used to assess diagnoses. Dysfunctional beliefs related to Beck and colleagues' (2006) and Mansell's (2007) cognitive models were assessed. RESULTS: Unlike offspring of parents with MDD or no mood disorder, those with a parent with bipolar disorder endorsed significantly more dysfunctional cognitions associated with extreme appraisal of mood states, even after controlling for their own mood diagnosis. Once affected by a bipolar or depressive disorder, offspring endorsed dysfunctional cognitions across measures. CONCLUSIONS: Dysfunctional cognitions, particularly those related to appraisals of mood states and their potential consequences, are evident in young adults with a parent who has bipolar disorder and may represent targets for psychotherapeutic intervention.

The bilingual experience is believed to impact brain development and, possibly, cognitive performance. Subcortical structures, including the striatum and white matter, are believed related to confrontation naming performance among bilingual individuals with later age of acquisition (AoA) and lower proficiency of a second language (L2). However, these findings are primarily derived from healthy adult samples, although there is clinical significance for the interpretation of naming performance. The present study examined whether striatal and white matter lesions were associated with naming tasks in clinic-referred bilingual veterans (n = 29) and whether L2 AoA moderated this relationship. Clinically rated lesions, without regard for AoA, were not consistently correlated with naming performance. Moderation models (lesion × AoA) were significant across naming tasks (i.e., naming scores were negatively correlated with striatal lesions with increasing AoA). Effect sizes were higher among striatal models as compared to white matter models. Results extend prior neuroimaging findings with healthy bilinguals that AoA moderates the relationship between subcortical lesions and naming performance in bilingual patients, and suggests that clinicians should consider specifics of bilingual experience when interpreting test scores.

Use of multiple performance validity tests (PVTs) may best identify invalid performance, though few studies have examined the utility and accuracy of combining PVTs. This study examined the following PVTs in the Advanced Clinical Solutions (ACS) package to determine their utility alone and in concert: Word Choice Test (WCT), Reliable Digit Span (RDS), and Logical Memory Recognition (LMR). Ninety-three veterans participated in clinical neuropsychological evaluations to determine presence of cognitive impairment; 25% of the performances were deemed invalid via criterion PVTs. Classification accuracy of the ACS measures was assessed via receiver operating characteristic curves, while logistic regressions determined utility of combining these PVTs. The WCT demonstrated superior classification accuracy compared to the two embedded measures of the ACS, even in veterans with cognitive impairment. The two embedded measures (even when used in concert) exhibited inadequate classification accuracy. A combined model with all three ACS PVTs similarly demonstrated little benefit of the embedded indicators over the WCT alone. Results suggest the ACS WCT has utility for detecting invalid performance in a clinical sample with likely cognitive impairment, though the embedded ACS measures (RDS and LMR) may have limited incremental utility, particularly in individuals with cognitive impairment.

OBJECTIVE: Premorbid estimates of intellectual functioning are a key to assessment. This study aimed to compare 3 common measures and assess their accuracy: the Test of Premorbid Functioning (TOPF), Oklahoma Premorbid Intelligence Estimate (OPIE-3), and what is commonly referred to as the Barona equation. We also sought to provide appropriate adjustment considering the Flynn effect. METHOD: The sample consisted of a cross-section of 189 outpatient veterans receiving neuropsychological assessment including the TOPF and Wechsler Adult Intelligence Scale, 4th ed. (WAIS-IV). Paired sample t tests assessed differences between IQ models. Correlations for all models and actual WAIS-IV Full Scale IQ (FSIQ) to establish which model best predicted variance in current IQ. Mean differences were evaluated to establish how closely the models approximated WAIS-IV FSIQ. RESULTS: The Barona equation estimated higher premorbid IQ than TOPF Simple Demographics Model; however, differences between the models were nonsignificant after a Flynn effect correction for the Barona equation (.23 IQ points per year). The OPIE-3 correlated with FSIQ but overestimated the FSIQ, demonstrating the Flynn effect. TOPF performance models (include word reading) characterized the variance of IQ scores best, but the Flynn-adjusted Barona equation had the smallest mean difference from the actual WAIS-IV FSIQ of any prediction model. CONCLUSION: Demographic models for premorbid IQ accurately estimate IQ in adult populations when normed on the test used to measure IQ, or when adjusted for the Flynn effect. A Flynn-corrected Barona score provided a more accurate estimation of WAIS-IV FSIQ than the TOPF or the OPIE-3. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

This study examined the Word Choice Test's (WCT) utility as a performance validity test in a mixed clinical sample of veterans referred for neuropsychological evaluation. Participants completed Green's Word Memory Test (WMT), WCT, and Test of Memory Malingering (TOMM) Trial 1. Using the WMT as the criterion for valid performance, logistic regressions examined the WCT and TOMM's classification accuracy for those with and without cognitive impairment (CI). Receiver operating characteristic curves were used to establish cut scores which maximized the sensitivity/specificity of each measure. In those without CI, both tests showed good classification accuracy (86.7% and 85.0%, respectively). Among those with CI, the TOMM retained good classification accuracy (82.3%), while the WCT's decreased considerably (69.4%). Optimal WCT cut scores differed based on impairment status, with a higher sensitivity/specificity trade-off among those with CI. Successful performance on the WCT appeared to rely more heavily on cognitive processes unrelated to performance validity.

The Department of Veterans Affairs Polytrauma Transitional Rehabilitation Program was established to extend the rehabilitation of veterans and active duty service members past the acute phase and reintegrate them into the community. Effective community reintegration is best achieved with a diverse interdisciplinary team that treats patients' physical, cognitive, and psychological deficits in a collaborative approach. Barriers, such as lack of accurate awareness of functional limitations and premorbid psychosocial stressors, can limit the recovery process. Recovery from polytrauma injuries is often a lifelong process, with the goal of maximizing functional independence and quality of life.

Embedded performance validity tests (PVTs) allow for continuous assessment of invalid performance throughout neuropsychological test batteries. This study evaluated the utility of the Wechsler Memory Scale-Fourth Edition (WMS-IV) Logical Memory (LM) Recognition score as an embedded PVT using the Advanced Clinical Solutions (ACS) for WAIS-IV/WMS-IV Effort System. This mixed clinical sample was comprised of 97 total participants, 71 of whom were classified as valid and 26 as invalid based on three well-validated, freestanding criterion PVTs. Overall, the LM embedded PVT demonstrated poor concordance with the criterion PVTs and unacceptable psychometric properties using ACS validity base rates (42% sensitivity/79% specificity). Moreover, 15-39% of participants obtained an invalid ACS base rate despite having a normatively-intact age-corrected LM Recognition total score. Receiving operating characteristic curve analysis revealed a Recognition total score cutoff of < 61% correct improved specificity (92%) while sensitivity remained weak (31%). Thus, results indicated the LM Recognition embedded PVT is not appropriate for use from an evidence-based perspective, and that clinicians may be faced with reconciling how a normatively intact cognitive performance on the Recognition subtest could simultaneously reflect invalid performance validity.

Objective: Performance validity tests (PVTs) are essential in neuropsychological evaluations; however, it has been questioned how PVTs function in the context of cognitive impairment, and whether cognitive impairment alone is sufficient to cause PVT failure. Further, there is concern that some clinicians will disregard failed PVTs due to their perception that failures represent false-positive errors secondary to cognitive impairment. This study examined patterns associated with cognitively impaired versus noncredible performance across a battery of PVTs and neuropsychological tests. Additionally, the impact of VA service-connection and disability-seeking status on test validity was investigated. Method: A mixed-clinical sample of 103 veterans were administered six PVTs and neuropsychological tests. Performance was compared across three groups: valid-cognitively unimpaired, valid-cognitively impaired, and noncredible. Results: Significant PVT score differences and failure rates emerged across the three groups, with nonsignificant to small differences between valid-unimpaired and valid-impaired groups, and large differences between impaired and noncredible groups. In contrast, there were nonsignificant to small differences on neuropsychological tests between the valid-impaired and noncredible groups, indicating that impaired participants performed significantly better on PVTs despite comparable neurocognitive test scores. Service-connection rating itself was not associated with PVT failure, but an active disability claim to increase and/or establish service connection was associated with worse PVT performance. Conclusion: This study supports the use of multiple PVTs during evaluations of patients with varied cognitive abilities. Results indicated increased risk of PVT failure in patients who were seeking initiation/increase in service-connected payments, and shows that cognitive impairment does not cause PVT failure.

OBJECTIVE: Embedded performance validity tests (PVTs) within the Hopkins Verbal Learning Test-Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT-R) were recently identified. This study aimed to further validate/replicate these embedded PVTs. METHOD: Eighty clinically referred veterans who underwent neuropsychological evaluation were included. Validity groups were established by passing/failing 2-3 well-validated PVTs, with 75% (n = 60) classified as valid and 25% (n = 20) noncredible. Fifty-two percent of valid participants were cognitively impaired. RESULTS: HVLT-R Recognition Discrimination (RD) of ≤5 yielded 67% sensitivity/80% specificity for identifying noncredible performance. Removal of seven valid participants with an amnestic profile who produced a false positive, improved specificity to 92%, which replicated the original findings. Replication efforts failed for BVMT-R Percent Retained; however, significant findings for RD were elucidated. CONCLUSION: Replication efforts were positive for the HVLT-R embedded PVT, corroborating its ability to identify invalid performance in this heterogeneous clinical veteran sample with and without cognitive impairment.

OBJECTIVE: This study cross-validated the Dot Counting Test (DCT) as a performance validity test (PVT) among a mixed clinical veteran sample. Completion time and error patterns also were examined by validity group and cognitive impairment status. METHOD: This cross-sectional study included 77 veterans who completed the DCT during clinical evaluation. Seventy-four percent (N = 57) were classified as valid and 26% as noncredible (N = 20) via the Word Memory Test (WMT) and Test of Memory Malingering (TOMM). Among valid participants, 47% (N = 27) were cognitively impaired, and 53% (N = 30) were unimpaired. RESULTS: DCT performance was not significantly associated with age, education, or bilingualism. Seventy-five percent of the overall sample committed at least one error across the 12 stimulus cards; however, valid participants had a 27% higher rate of 0 errors, while noncredible participants had a 35% higher rate of ≥4 errors. Overall, noncredible individuals had significantly longer completion times, more errors, and higher E-scores. Conversely, those with cognitive impairment had longer completion times, but comparable errors to their unimpaired counterparts. Finally, DCT E-scores significantly predicted group membership with 83.1% classification accuracy and an area under the curve of .87 for identifying invalid performance. The optimal cut-score of 15 was associated with 70% sensitivity and 88% specificity. CONCLUSION: The DCT demonstrated good classification accuracy and sensitivity/specificity for identifying noncredible performance in this mixed clinical veteran sample, suggesting utility as a non-memory-based PVT with this population. Moreover, cognitive impairment significantly contributed to slower completion times, but not reduced accuracy.
