Abstract
OBJECTIVES To determine the association between self-reported emotional and cognitive symptoms and participation outcomes in chronic traumatic brain injury (TBI) and to explore the relative contribution of self-reported versus performance-based cognition to participation outcomes. SETTING Community. PARTICIPANTS Community-dwelling adults ( n = 135) with a lifetime history of mild to severe TBI. DESIGN Secondary analysis of a cross-sectional study on neurobehavioral symptoms in chronic TBI. MAIN MEASURES Behavioral Assessment Screening Tool (BAST) (Negative Affect, Fatigue, Executive Dysfunction, Impulsivity, Substance Abuse subscales) measured self-reported neurobehavioral symptoms; Participation Assessment with Recombined Tools (Productivity, Social Relations, and Out and About) measured self-reported participation outcomes; and Brief Test of Adult Cognition by Telephone (BTACT) measured performance-based cognition (Episodic Memory and Executive Function summary scores) in a subsample ( n = 40). RESULTS The BAST Executive Dysfunction was significantly associated with less frequent participation and had the strongest effect on participation in all participation domains. No other BAST subscales were associated with participation, after adjusting for all subscale scores and age, with the exception of BAST Impulsivity, which was associated with more frequent Social Relationships. Exploratory analysis in the sample including the BTACT revealed that, after accounting for subjective Executive Dysfunction using the BAST, performance-based Executive Function was associated with Productivity and Working Memory was associated with Social Relations, but neither was associated with being Out and About; the BAST Executive Dysfunction remained significant in all models even after including BTACT scores. CONCLUSIONS Self-reported Executive Dysfunction contributed to participation outcomes after mild to severe TBI in community-dwelling adults, whereas self-reported emotional and fatigue symptoms did not. Performance-based cognition measures may capture different variability in participation after injury.

Abstract
Cognitive outcome for mild traumatic brain injury (mTBI) with positive brain imaging (complicated mTBI) was compared with that for mTBI with normal imaging (uncomplicated mTBI) and with moderate to severe TBI, using meta-analysis. Twenty-three studies utilizing objective neurocognitive tests were included in the analysis. At less than 3 months post-injury, complicated mTBI was associated with poorer cognitive outcomes than uncomplicated mTBI, but deficits were not comparable to those with moderate-severe TBI. After 3 months post-injury, a similar pattern was detected. Beyond 3 months, deficits in complicated mTBI relative to those with uncomplicated mTBI were present in processing speed, memory, executive function, and language, although the latter may be the result of reduced semantic fluency. The effect size of deficits in these domains was more marked in moderate-severe TBI. The available data support the use of complicated mTBI as a distinct classification in the prediction of cognitive outcome. The extent of cognitive deficit in complicated mTBI was small and unlikely to cause significant disability. However, patients with complicated mTBI constitute a broad category encompassing individuals who may differ markedly in the nature and extent of intracranial imaging abnormality, and further studies are warranted. Limitations of the available studies include small, selected samples; variations in TBI severity classification; absence of validity ("effort") testing; differing imaging methodology; and lack of long-term follow-up.

Abstract
BACKGROUND/OBJECTIVES The objective was to assess the relationships between neuropsychological impairments, functional outcome and life satisfaction in a longitudinal study of patients after a severe traumatic brain injury (TBI) (PariS-TBI study). PATIENTS Out of 243 survivors, 86 were evaluated 8 years post-injury. They did not significantly differ from patients lost-to-follow up except for the latter being more frequently students or unemployed before the injury. METHODS Outcome measures included the Glasgow Outcome Scale-Extended (GOS-E), a functional independence questionnaire, employment, mood, fatigue and satisfaction with life. Neuropsychological outcome was assessed by two ways: performance-based outcome measures, using neuropsychological tests and patient and relative-based measures. RESULTS Neuropsychological measures were not significantly related to initial injury severity nor to gender, but were significantly related to age and education. After statistical correction for multiple comparisons, cognitive testing and cognitive questionnaires were significantly correlated with most outcome measures. By contrast, satisfaction with life was only related with patient-rated questionnaires. A regression analysis showed that the Trail-Making-Test-A was the best predictor of functional outcome, in addition to education duration. CONCLUSIONS Cognitive measures, particularly slowed information processing speed, were significant indicators of functional outcome at a long-term post-injury, beyond and above demographics or injury severity measures.

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.

Assessment of Executive Function in Patients with Traumatic Brain Injury with the Wisconsin Card-Sorting Test. Brain Sci 2020; 10:brainsci10100699.

Abstract
This review aimed at providing a brief and comprehensive summary of recent research regarding the use of the Wisconsin Card-Sorting Test (WCST) to assess executive function in patients with traumatic brain injury (TBI). A bibliographical search, performed in PubMed, Web of Science, Scopus, Cochrane Library, and PsycInfo, targeted publications from 2010 to 2020, in English or Spanish. Information regarding the studies’ designs, sample features and use of the WCST scores was recorded. An initial search eliciting 387 citations was reduced to 47 relevant papers. The highest proportion of publications came from the United States of America (34.0%) and included adult patients (95.7%). Observational designs were the most frequent (85.1%), the highest proportion being cross-sectional or case series studies. The average time after the occurrence of the TBI ranged from 4 to 62 years in single case studies, and from 6 weeks up to 23.5 years in the studies with more than one patient. Four studies compared groups of patients with TBI according to the severity (mild, moderate and/or severe), and in two cases, the studies compared TBI patients with healthy controls. Randomized control trials were seven in total. The noncomputerized WCST version including 128 cards was the most frequently used (78.7%). Characterization of the clinical profile of participants was the most frequent purpose (34.0%). The WCST is a common measure of executive function in patients with TBI. Although shorter and/or computerized versions are available, the original WCST with 128 cards is still used most often. The WCST is a useful tool for research and clinical purposes, yet a common practice is to report only one or a few of the possible scores, which prevents further valid comparisons across studies. Results might be useful to professionals in the clinical and research fields to guide them in assessment planning and proper interpretation of the WCST scores.

Abstract
Rapport is an important component of neuropsychological test administration; however, there is a lack of psychometrically sound measures of rapport in the context of neuropsychological assessment. The purpose of this study was to explore adapting measures of the psychotherapeutic alliance specifically to neuropsychological test administration and investigate their feasibility and construct validity. College students (N = 126) were administered a brief battery of neuropsychological tests in either a high-rapport or low-rapport condition. Participants in the high-rapport condition rated rapport as being higher, suggesting that the items captured the nature of the interpersonal interaction between examiner and examinee. The results suggest the feasibility of adapting items from measures of the psychotherapeutic alliance for measuring rapport in neuropsychological testing. This article introduces the Barnett Rapport Questionnaire, a measure of rapport in the context of neuropsychological assessment.

Abstract
Objective: The purpose of this critical review was to evaluate the current state of research regarding the incremental value of neuropsychological assessment in clinical practice, above and beyond what can be accounted for on the basis of demographic, medical, and other diagnostic variables. The focus was on neurological and other medical conditions across the lifespan where there is known risk for presence or future development of cognitive impairment.Method: Eligible investigations were group studies that had been published after 01/01/2000 in English in peer-reviewed journals and that had used standardized neuropsychological measures and reported on objective outcome criterion variables. They were identified through PubMed and PsychInfo electronic databases on the basis of predefined specific selection criteria. Reference lists of identified articles were also reviewed to identify potential additional sources. The Grades of Recommendation, Assessment, Development and Evaluation Working Group's (GRADE) criteria were used to evaluate quality of studies.Results: Fifty-six studies met the final selection criteria, including 2 randomized-controlled trials, 9 prospective cohort studies, 12 retrospective cohort studies, 21 inception cohort studies, 2 case control studies, and 10 case series studies. The preponderance of the evidence was strongly supportive with regard to the incremental value of neuropsychological assessment in the care of persons with mild cognitive impairment/dementia and traumatic brain injury. Evidence was moderately supportive with regard to stroke, epilepsy, multiple sclerosis, and attention-deficit/hyperactivity disorder. Participation in neuropsychological evaluations was also associated with cost savings.Conclusions: Neuropsychological assessment can improve both diagnostic classification and prediction of long-term daily-life outcomes in patients across the lifespan. Future high-quality prospective cohort studies and randomized-controlled trials are necessary to demonstrate more definitively the incremental value of neuropsychological assessment in the management of patients with various neurological and other medical conditions.

Abstract
The objectives were to investigate the frequency of return-to-work (RTW) one year after severe traumatic brain injury (sTBI: Glasgow Coma Scale, GCS 3-8) and to identify which demographic and injury-related characteristics and neurocognitive factors are associated with RTW. This study is part of a prospective national study on sTBI conducted in all four Norwegian Trauma Referral Centres, including patients aged >15 years over a period of three years (n = 378). For the purpose of this study, only pre-employed individuals of working age (16 to 67 years) were investigated for RTW (n = 143), and of these, 104 participants underwent neuropsychological testing. Measures of acute injury severity, neuropsychological composite scores (Memory, Processing Speed, Executive Functions) at the one-year follow-up, and the Behaviour Rating Inventory of Executive Functions (patient- and relative reports) were explored as predictors of RTW. The frequency of RTW was 54.5%. Multivariate logistic regression analyses identified younger age, shorter length of stay in intensive care, better Processing Speed scores, and lower levels of metacognitive difficulties as rated by relatives as significant predictors of RTW. Findings support the importance of neuropsychological measures in predicting long-term RTW and highlight the need to address neurocognitive and behavioural difficulties to improve RTW after sTBI.

Abstract
INTRODUCTION The apolipoprotein E (APOE) ε4 allele associates with memory impairment in neurodegenerative diseases. Its association with memory after mild traumatic brain injury (mTBI) is unclear. METHODS mTBI patients (Glasgow Coma Scale score 13-15, no neurosurgical intervention, extracranial Abbreviated Injury Scale score ≤1) aged ≥18 years with APOE genotyping results were extracted from the Transforming Research and Clinical Knowledge in Traumatic Brain Injury Pilot (TRACK-TBI Pilot) study. Cohorts determined by APOE-ε4(+/-) were assessed for associations with 6-month verbal memory, measured by California Verbal Learning Test, Second Edition (CVLT-II) subscales: Immediate Recall Trials 1-5 (IRT), Short-Delay Free Recall (SDFR), Short-Delay Cued Recall (SDCR), Long-Delay Free Recall (LDFR), and Long-Delay Cued Recall (LDCR). Multivariable regression controlled for demographic factors, seizure history, loss of consciousness, posttraumatic amnesia, and acute intracranial pathology on computed tomography (CT). RESULTS In 114 mTBI patients (APOE-ε4(-)=79; APOE-ε4(+)=35), ApoE-ε4(+) was associated with long-delay verbal memory deficits (LDFR: B = -1.17 points, 95% CI [-2.33, -0.01], p = .049; LDCR: B = -1.58 [-2.63, -0.52], p = .004), and a marginal decrease on SDCR (B = -1.02 [-2.05, 0.00], p = .050). CT pathology was the strongest predictor of decreased verbal memory (IRT: B = -8.49, SDFR: B = -2.50, SDCR: B = -1.85, LDFR: B = -2.61, LDCR: B = -2.60; p < .001). Seizure history was associated with decreased short-term memory (SDFR: B = -1.32, p = .037; SDCR: B = -1.44, p = .038). CONCLUSION The APOE-ε4 allele may confer an increased risk of impairment of 6-month verbal memory for patients suffering mTBI, with implications for heightened surveillance and targeted therapies. Acute intracranial pathology remains the driver of decreased verbal memory performance at 6 months after mTBI.
