Detecting feigned cognitive impairment using pupillometry on the Warrington Recognition Memory Test for Words.

OBJECTIVE: Pupillometry provides information about physiological and psychological processes related to cognitive load, familiarity, and deception, and it is outside of conscious control. This study examined pupillary dilation patterns during a performance validity test (PVT) among adults with true and feigned impairment of traumatic brain injury (TBI). PARTICIPANTS AND METHODS: Participants were 214 adults in three groups: adults with bona fide moderate to severe TBI (TBI; n = 51), healthy comparisons instructed to perform their best (HC; n = 72), and healthy adults instructed and incentivized to simulate cognitive impairment due to TBI (SIM; n = 91). The Recognition Memory Test (RMT) was administered in the context of a comprehensive neuropsychological battery. Three pupillary indices were evaluated. Two pure pupil dilation (PD) indices assessed a simple measure of baseline arousal (PD-Baseline) and a nuanced measure of dynamic engagement (PD-Range). A pupillary-behavioral index was also evaluated. Dilation-response inconsistency (DRI) captured the frequency with which examinees displayed a pupillary familiarity response to the correct answer but selected the unfamiliar stimulus (incorrect answer). RESULTS: All three indices differed significantly among the groups, with medium-to-large effect sizes. PD-Baseline appeared sensitive to oculomotor dysfunction due to TBI; adults with TBI displayed significantly lower chronic arousal as compared to the two groups of healthy adults (SIM, HC). Dynamic engagement (PD-Range) yielded a hierarchical structure such that SIM were more dynamically engaged than TBI followed by HC. As predicted, simulators engaged in DRI significantly more frequently than other groups. Moreover, subgroup analyses indicated that DRI differed significantly for simulators who scored in the invalid range on the RMT (n = 45) versus adults with genuine TBI who scored invalidly (n = 15). CONCLUSIONS: The findings support continued research on the application of pupillometry to performance validity assessment: Overall, the findings highlight the promise of biometric indices in multimethod assessments of performance validity.

Emotion-Focused Psychodynamic Interview for People with Chronic Musculoskeletal Pain and Childhood Adversity: A Randomized Controlled Trial.

Childhood adversity and emotional conflicts are associated with the presence and severity of chronic musculoskeletal pain (CMP), yet common treatments for CMP do not address such risk factors. We developed a single session, emotion-focused psychodynamic interview, based on Emotional Awareness and Expression Therapy and Intensive Short-term Psychodynamic Therapy, and we tested the interview's effects on pain-related outcomes and potential psychological mediators in a randomized, controlled trial. Adults (N = 91; ages 21-70, M = 44.64; 87.9% women) reporting CMP and at least 3 adverse childhood experiences completed measures at baseline and 6-week follow-up. Participants were randomized to immediate interview or waitlist control conditions. The 90-minute interview was conducted via videoconference, and the interviewer elicited disclosure of adversities and conflicts, linked these with pain, and encouraged the experience and expression of adaptive emotions. Analyses indicated that conditions did not differ significantly on change in pain severity; however, compared to control, the interview led to a significantly greater reduction in pain interference (P = .016, ηp2 = .05) and a similar trend for anxiety (P = .058, ηp2 = .04). The interview also significantly changed several potential mediators: pain-related anxiety (P = .008, ηp2 = .06), pain controllability (P = .016, ηp2 = .06), and psychological (P < .001, ηp2 = .15) and brain attributions (P = .022, ηp2 = .05) for pain. Participants viewed the interview as very valuable. We conclude that addressing childhood adversities and conflicts in a psychodynamic interview is beneficial for people with CMP. PERSPECTIVE: This study found that, compared to waitlist control, a 90-minute, remotely-administered, emotion-focused, psychodynamic interview improved pain interference, and anxiety among adults with chronic musculoskeletal pain and childhood adversity. Intensive emotional work can be done in a single session to the benefit of patients with chronic musculoskeletal pain.

Cognitive enrichment and education quality moderate cognitive dysfunction in black and white adults with multiple sclerosis.

OBJECTIVE: To examine the extent to which three sociobehavioral proxies of cognitive reserve-years of education, education quality, and cognitive enrichment-differ in their prediction of cognitive performance among Black and White people with MS (PwMS). METHODS: 82 PwMS (Black n = 41, White n = 41) underwent a neurological examination and a neuropsychological evaluation that included tests of word recognition (Wechsler Test of Adult Reading) as well as measures of verbal memory, visuospatial memory, and processing speed (the Brief International Cognitive Assessment for MS; BICAMS). Participants rated their lifetime engagement in various cognitively-enriching activities (Cognitive Reserve Scale). RESULTS: For the full sample, education quality and cognitive enrichment were more strongly associated with cognitive performance than were years of education. Cognitive enrichment was not associated with cognitive performance among participants with high education quality. In contrast, among participants with low education quality, cognitive enrichment was strongly associated with cognitive performance, suggesting that high engagement in cognitively-enriching activities provided similar protection to high education quality. Furthermore, among Black participants, cognitive enrichment and educational quality moderated the relationship between disability level and cognitive performance. In contrast, among White participants, cognitive enrichment did not provide additional protection beyond the buffering effect of education quality. CONCLUSIONS: PwMS can successfully build reserve through multiple routes, including formal education or informal cognitive enrichment. Treatment for MS should incorporate cognitively-enriching activities to build resilience against cognitive decline, particularly for members of marginalized racial/ethnic groups, who are at greatest risk for poor health outcomes, and for whom years of education may not best reflect education quality.

Experiential training of mental health graduate students in emotional processing skills: A randomized, controlled trial.

Emotional processing interventions for trauma and psychological conflicts are underutilized. Lack of adequate training in emotional processing techniques and therapists' lack of confidence in utilizing such interventions are barriers to implementation. We developed and tested an experiential training to improve trainees' performance in a set of transtheoretical emotional processing skills: eliciting patient disclosure of difficult experiences, responding to defenses against disclosure, and eliciting adaptive emotions. Mental health trainees (N = 102) were randomized to experiential or standard training, both of which presented a 1-hr individual session administered remotely. Before and after training and at 5-week follow-up, trainees were videorecorded as they responded to videos of challenging therapy situations, and responses were coded for demonstrated skill. Trainees also completed measures of therapeutic self-efficacy, anxiety, and depression at baseline and follow-up. Repeated-measures analysis of variance indicated all three skills increased from pre- to posttraining for both conditions, which were maintained at follow-up. Importantly, experiential training led to greater improvements than standard training in the skills of eliciting disclosure (η² = .05, p = .03), responding to defenses (η² = .04, p = .05), and encouraging adaptive emotions (η² = .23, p < .001) at posttraining, and the training benefits for eliciting disclosure were maintained at follow-up. Both conditions led to improved self-efficacy. Trainees' anxiety decreased in the standard training, but not in the experiential. One session of experiential training improved trainees' emotional processing therapy skills more than didactic training, although more training and practice likely are needed to yield longer lasting skills.

Incremental validity of brief and abbreviated neuropsychological tests toward predicting functional outcomes in multiple sclerosis.

OBJECTIVE: This study examined the relationships among functional outcomes and performance on standard-length and abbreviated cognitive screening measures for multiple sclerosis (MS). METHOD: 72 adults with MS underwent neurological examination and cognitive screening. They completed standard-length and abbreviated versions of tests from the Minimal Assessment of Cognitive Function in MS (MACFIMS), the abbreviated aMACFIMS, and the Brief International Cognitive Assessment for MS (BICAMS). Functional outcomes included neurological disability, physical and psychological dysfunction, and employment status. RESULTS: Concordance of impairment classifications was examined between standard-length and abbreviated tests using logistic regression and ROC curve analyses. Overall, the abbreviated test versions showed a broad range of concordance with impairment classifications made using the full-length tests. Processing speed was the strongest correlate of neurological disability and employment status; immediate recall was the strongest predictor of subjective physical dysfunction. Test performance provided unique value toward predicting neurological disability and employment status, but not physical and psychological dysfunction. CONCLUSIONS: The findings replicate some support for abbreviated tests in MS assessment, although caveats regarding loss of validity associated with abbreviation remain. The findings extend prior research showing that abbreviated tests of processing speed and immediate recall can provide unique predictive information regarding objective functional outcomes.

Barriers to driving and psychosocial outcomes after traumatic brain injury.

OBJECTIVE: Examine considerations and perceived barriers to return to driving, and their association with psychosocial outcomes among adults with traumatic brain injury (TBI) who were not driving. METHODS: 174 adults with moderate-to-severe TBI enrolled in the TBI Model System participated in this cross-sectional study. All participants were drivers prior to their TBI. Outcome measures included the Barriers to Driving Questionnaire, Disability Rating Scale, Patient Health Questionnaire-9, General Anxiety Disorder-7, and Satisfaction With Life Scale. Descriptive analyses examined considerations and barriers to driving, including differences associated with demographic characteristics. Moderation analyses investigated the extent to which disability moderated the relationship between barriers and psychosocial outcomes. RESULTS: Social barriers were the most strongly endorsed domain, whereas physical barriers were endorsed least. The profile of endorsements differed for men and women, and for Black and White participants, on both theoretical considerations in returning to drive and experiences of barriers in doing so. Disability level moderated the relationship between barriers to driving and depression and life satisfaction, but not anxiety. CONCLUSION: The experience of barriers to driving is differentially associated with psychosocial outcomes among nondriving adults with TBI. Adults with low disability appear to be at risk for distress, even compared to other nondrivers.

Was the COVID-19 Pandemic Associated with Gender Disparities in Authorship of Manuscripts Submitted to Clinical Neuropsychology Journals?

OBJECTIVE: The COVID-19 pandemic exacerbated gender disparities in some academic disciplines. This study examined the association of the pandemic with gender authorship disparities in clinical neuropsychology (CN) journals. METHOD: Author bylines of 1,018 initial manuscript submissions to four major CN journals from March 15 through September 15 of both 2019 and 2020 were coded for binary gender. Additionally, authorship of 40 articles published on pandemic-related topics (COVID-19, teleneuropsychology) across nine CN journals were coded for binary gender. RESULTS: Initial submissions to these four CN journals increased during the pandemic (+27.2%), with comparable increases in total number of authors coded as either women (+23.0%) or men (+25.4%). Neither the average percentage of women on manuscript bylines nor the proportion of women who were lead and/or corresponding authors differed significantly across time. Moreover, the representation of women as authors of pandemic-related articles did not differ from expected frequencies in the field. CONCLUSIONS: Findings suggest that representation of women as authors of peer-reviewed manuscript submissions to some CN journals did not change during the initial months of the COVID-19 pandemic. Future studies might examine how risk and protective factors may have influenced individual differences in scientific productivity during the pandemic.

Crash Risk Following Return to Driving After Moderate-to-Severe TBI: A TBI Model Systems Study.

OBJECTIVE: To examine motor vehicle crash frequency and risk factors following moderate-to-severe traumatic brain injury (TBI). SETTING: Eight TBI Model Systems sites. Participants: Adults ( N = 438) with TBI who required inpatient acute rehabilitation. DESIGN: Cross-sectional, observational design. MAIN MEASURES: Driving survey completed at phone follow-up 1 to 30 years after injury. RESULTS: TBI participants reported 1.5 to 2.5 times the frequency of crashes noted in the general population depending on the time frame queried, even when accounting for unreported crashes. Most reported having no crashes; for those who experienced a crash, half of them reported a single incident. Based on logistic regression, age at survey, years since injury, and perception of driving skills were significantly associated with crashes. CONCLUSION: Compared with national statistics, crash risk is higher following TBI based on self-report. Older age and less time since resuming driving were associated with lower crash risk. When driving was resumed was not associated with crash risk. These results do not justify restricting people from driving after TBI, given that the most who resumed driving did not report experiencing any crashes. However, there is a need to identify and address factors that increase crash risk after TBI.

Utility of WAIS-IV Digit Span indices as measures of performance validity in moderate to severe traumatic brain injury.

Objective: The addition of Sequencing to WAIS-IV Digit Span (DS) brought about new Reliable Digit Span (RDS) indices and an Age-Corrected Scaled Score that includes Sequencing trials. Reports have indicated that these new performance validity tests (PVTs) are superior to the traditional RDS; however, comparisons in the context of known neurocognitive impairment are sparse. This study compared DS-derived PVT classification accuracies in a design that included adults with verified TBI. Methods: Participants included 64 adults with moderate-to-severe TBI (TBI), 51 healthy adults coached to simulate TBI (SIM), and 78 healthy comparisons (HC). Participants completed the WAIS-IV DS subtest in the context of a larger test battery. Results: Kruskal-Wallis tests indicated that all DS indices differed significantly across groups. Post hoc contrasts revealed that only RDS Forward and the traditional RDS differed significantly between SIM and TBI. ROC analyses indicated that RDS variables were comparable predictors of SIM vs. HC; however, the traditional RDS showed the highest sensitivity when approximating 90% specificity for SIM vs. TBI. A greater percentage of TBI scored RDS Sequencing < 1 compared to SIM and HC. Conclusion: In the context of moderate-to-severe TBI, the DS-derived PVTs showed comparable discriminability. However, the Greiffenstein et al. traditional RDS demonstrated the best classification accuracy with respect to specificity/sensitivity balance. This relative superiority may reflect that individuals with verified TBI are more likely to perseverate on prior instructions during DS Sequencing. Findings highlight the importance of including individuals with verified TBI when evaluating and developing PVTs.

Time and money: Exploring enhancements to performance validity research designs.

INTRODUCTION: The study examined the effect of preparation time and financial incentives on healthy adults' ability to simulate traumatic brain injury (TBI) during neuropsychological evaluation. METHOD: A retrospective comparison of two TBI simulator group designs: a traditional design employing a single-session of standard coaching immediately before participation (SIM-SC; n = 46) and a novel design that provided financial incentive and preparation time (SIM-IP; n = 49). Both groups completed an ecologically valid neuropsychological test battery that included widely-used cognitive tests and five common performance validity tests (PVTs). RESULTS: Compared to SIM-SC, SIM-IP performed significantly worse and had higher rates of impairment on tests of processing speed and executive functioning (Trails A and B). SIM-IP were more likely than SIM-SC to avoid detection on one of the PVTs and performed somewhat better on three of the PVTs, but the effects were small and non-significant. SIM-IP did not demonstrate significantly higher rates of successful simulation (i.e., performing impaired on cognitive tests with <2 PVT failures). Overall, the rate of the successful simulation was ∼40% with a liberal criterion, requiring cognitive impairment defined as performance >1 SD below the normative mean. At a more rigorous criterion defining impairment (>1.5 SD below the normative mean), successful simulation approached 35%. CONCLUSIONS: Incentive and preparation time appear to add limited incremental effect over traditional, single-session coaching analog studies of TBI simulation. Moreover, these design modifications did not translate to meaningfully higher rates of successful simulation and avoidance of detection by PVTs.

Driving patterns, confidence, and perception of abilities following moderate to severe traumatic brain injury: a TBI model system study.

OBJECTIVE: Describe driving patterns following moderate-to-severe traumatic brain injury (TBI). Participants: Adults (N = 438) with TBI that required inpatient acute rehabilitation who had resumed driving. DESIGN: Cross-sectional, observational design. SETTING: Eight TBI Model System sites. MAIN MEASURES: A driving survey was completed at phone follow-up. RESULTS: Most respondents reported driving daily, although 41% reported driving less than before their injury. Driving patterns were primarily associated with employment, family income, sex, residence, and time since injury, but not injury severity. Confidence in driving was high for most participants and was associated with a perception that the TBI had not diminished driving ability. Lower confidence and perceived loss of ability were associated with altered driving patterns. CONCLUSION: Most people with moderate-to-severe TBI resume driving but perhaps not at pre-injury or normal levels compared to healthy drivers. Some driving situations are restricted. The relationship between low confidence/perceived loss of ability and driving patterns/restrictions suggests people with TBI are exhibiting some degree of caution consistent with those perceptions. Careful assessment of driving skills and monitoring during early stages of RTD is warranted, particularly for younger, male, and/or single drivers who express higher levels of confidence.

Detecting simulated versus bona fide traumatic brain injury using pupillometry.

Objective: Pupil dilation patterns are outside of conscious control and provide information regarding neuropsychological processes related to deception, cognitive effort, and familiarity. This study examined the incremental utility of pupillometry on the Test of Memory Malingering (TOMM) in classifying individuals with verified traumatic brain injury (TBI), individuals simulating TBI, and healthy comparisons. Method: Participants were 177 adults across three groups: verified TBI (n = 53), feigned cognitive impairment due to TBI (SIM, n = 52), and heathy comparisons (HC, n = 72). Results: Logistic regression and ROC curve analyses identified several pupil indices that discriminated the groups. Pupillometry discriminated best for the comparison of greatest clinical interest, verified TBI versus simulators, adding information beyond traditional accuracy scores. Simulators showed evidence of greater cognitive load than both groups instructed to perform at their best ability (HC and TBI). Additionally, the typically robust phenomenon of dilating to familiar stimuli was relatively diminished among TBI simulators compared to TBI and HC. This finding may reflect competing, interfering effects of cognitive effort that are frequently observed in pupillary reactivity during deception. However, the familiarity effect appeared on nearly half the trials for SIM participants. Among those trials evidencing the familiarity response, selection of the unfamiliar stimulus (i.e., dilation-response inconsistency) was associated with a sizeable increase in likelihood of being a simulator. Conclusions: Taken together, these findings provide strong support for multimethod assessment: adding unique performance assessments such as biometrics to standard accuracy scores. Continued study of pupillometry will enhance the identification of simulators who are not detected by traditional performance validity test scoring metrics.

Return to Driving After Moderate-to-Severe Traumatic Brain Injury: A Traumatic Brain Injury Model System Study.

OBJECTIVE: Describe who is able to return to driving (RTD) after moderate-to-severe traumatic brain injury (TBI), when this occurs, who maintains that activity, and the association with outcome. DESIGN: Cross-sectional descriptive study. SETTING: Eight follow-up sites of the TBI Model Systems (TBIMS) program. PARTICIPANTS: 618 participants enrolled in the TBIMS and 88 caregivers (N=706). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: A survey was completed from 1-30 years postinjury focusing on RTD. Descriptors included demographic information, injury severity, and current employment status. Outcome was assessed at the time of the interview, including depression, quality of life, functional status, and community participation. RESULTS: Of 706 respondents, 78% (N = 552) RTD, but 14% (N = 77) of these did not maintain that activity. Of those who RTD, 43% (N = 192) did so within 6 months of the injury and 92% did so within 24 months postinjury. The percentage of people driving after TBI did not differ significantly based on age at time of injury or follow-up. There were significant differences between drivers and nondrivers with respect to severity of injury, seizures, race, education, employment, rural vs urban setting, marital status, and family income. We performed a multivariate logistic regression to examine the association between driving status and demographic variables, adjusting for other variables in the model. The strongest associations were with current employment, family income, race, seizures, and severity of injury. Driving was associated with greater community participation, better functional outcomes, fewer symptoms of depression, and greater life satisfaction. CONCLUSIONS: Over a span of 30 years, three-quarters of people experiencing moderate-to-severe TBI return to driving a personal vehicle, although not everyone maintains this activity. Employment, race, family income, and seizures are strongly associated with RTD.

Pain anxiety and rehabilitation outcomes after acquired brain injury.

Purpose: The purpose of this study was to examine pain anxiety after acquired brain injury (ABI) and its relationship to rehabilitation outcomes.Materials and Method: Participants consisted of 89 adults with an ABI participating in outpatient rehabilitation therapy. They completed a battery of neuropsychological tests at baseline along with surveys of mood, health-related self-efficacy, and pain anxiety. Separately, occupational therapists assessed basic and instrumental activities of daily living (ADLs) as well as therapy engagement across treatment after the sixth session.Results: Individuals who reported high pain anxiety had fewer years of formal education, lower self-efficacy, and more emotional distress than those with low pain anxiety. Although Blacks were about half (56%) of the study sample, they comprised the majority (73.1%) of individuals in the high pain anxiety group. Pain anxiety was negatively related to therapy engagement. Moderation analysis using linear regression indicated that pain anxiety moderated the influence of self-efficacy on basic ADLs.Conclusions: Pain anxiety, particularly when high, is negatively associated with rehabilitation outcomes for individuals with ABI. Among those with high pain anxiety, health-related self-efficacy is an important resilience characteristic to improve functional outcomes. In rehabilitation therapy, pain anxiety provides a novel intervention target to enhance ABI recovery.

Effects of a Sexual Health Interview among Arab American Women: An Experimental Disclosure Study.

Although sexuality is an important aspect of peoples' health and well-being, many people-professionals and patients alike-find sexuality uncomfortable to discuss. In Arab culture, certain sexual thoughts and behaviors are taboo, particularly for women, and it is not known whether an interview in which Arab American women disclose their sexuality to a health professional would be well-received and beneficial or upsetting and harmful. This experimental study tested whether engaging in a disclosure-oriented sexual health interview affects Arab American women's sexual and psychological health. A sample of 134 Arab American women, ages 18-35 years (M = 20.6), completed self-report measures of sexual health and attitudes and psychological symptoms, and then were randomized to an interview or control (waitlist) condition. The 60-min disclosure interview inquired about sexual attitudes, experiences, and conflicts. Five weeks later, all participants completed follow-up measures. Post-interview reports suggest that participants responded favorably to the interview and generally benefited from participation. Analyses of covariance (controlling for baseline levels of the outcome measure) indicated that the interview led to significantly greater sexual satisfaction and less discomfort with sexual self-disclosure at 5-week follow-up, compared to controls; the two conditions did not differ on follow-up sexual self-schema, sexual self-esteem, or psychological symptoms. Moderation analyses revealed that participation in the interview differentially improved the sexual self-schema of women with no past sexual experience, compared to women with sexual experience. These experimental findings suggest the value, rather than the risk, of clinicians encouraging Arab American women to openly disclose and discuss their sexual experiences and attitudes in a confidential, empathic setting.

Performance validity assessment using response time on the Warrington Recognition Memory Test.

OBJECTIVE: The present study tested the incremental utility of response time (RT) on the Warrington Recognition Memory Test - Words (RMT-W) in classifying bona fide versus feigned TBI. METHOD: Participants were 173 adults: 55 with moderate to severe TBI, 69 healthy comparisons (HC) instructed to perform their best, and 49 healthy adults coached to simulate TBI (SIM). Participants completed a computerized version of the RMT-W in the context of a comprehensive neuropsychological battery. Groups were compared on RT indices including mean RT (overall, correct trials, incorrect trials) and variability, as well as the traditional RMT-W accuracy score. RESULTS: Several RT indices differed significantly across groups, although RMT-W accuracy predicted group membership more strongly than any individual RT index. SIM showed longer average RT than both TBI and HC. RT variability and RT for incorrect trials distinguished SIM-HC but not SIM-TBI comparisons. In general, results for SIM-TBI comparisons were weaker than SIM-HC results. For SIM-HC comparisons, classification accuracy was excellent for all multivariable models incorporating RMT-W accuracy with one of the RT indices. For SIM-TBI comparisons, classification accuracies for multivariable models ranged from acceptable to excellent discriminability. In addition to mean RT and RT on correct trials, the ratio of RT on correct items to incorrect items showed incremental predictive value to accuracy. CONCLUSION: Findings support the growing body of research supporting the value of combining RT with PVTs in discriminating between verified and feigned TBI. The diagnostic accuracy of the RMT-W can be improved by incorporating RT.

Engagement in rehabilitation therapy and functional outcomes among individuals with acquired brain injuries.

Purpose: The purpose was to examine the role of therapy engagement as a potential mediator for the relationship between neuropsychological performance and functional outcomes. Materials and method: Participants were 94 adults with medically documented ABI recruited from three outpatient rehabilitation clinics at the start of occupational therapy. Participants (57% men) ranged from 18 to 82 in age, with the majority (81%) having completed 12 or more years of education. They completed a comprehensive neuropsychological assessment at baseline. Separately, occupational therapists (OTs) assessed functional independence and disability at baseline and follow up. The OTs also rated the participants' therapy engagement. Results: Therapy engagement predicted functional outcomes and mediated the relationship between neuropsychological performance and outcomes. Moreover, therapy engagement accounted for unique variance in functional outcome, even after accounting for education, comorbid health conditions, emotional distress, apathy, and baseline functional ability. Conclusions: Engagement in therapy is a crucial patient characteristic in successful rehabilitation outcome. Cognitive deficits associated with ABI undermine full engagement in rehabilitation therapy, which in turn diminishes potential gains made in therapy and functional recovery. Neuropsychological assessment can enhance rehabilitation outcomes by identifying characteristics that underlie therapy engagement, which can ultimately be used to maximize the effectiveness of individualized treatment plans. Implications for rehabilitation Neuropsychological assessment can identify cognitive abilities that are strongly related to functional outcomes during occupational therapy for acquired brain injury. Therapy engagement is an important pathway by which neuropsychological impairment predicts functional outcomes after acquired brain injuries.

Detecting feigned traumatic brain injury with eye tracking during a test of performance validity.

OBJECTIVE: Eye-tracking is a promising technology to enhance assessment of performance validity. Research has established that ocular behaviors are reliable biomarkers of (un)conscious cognitive processes, and they have distinguished deceptive from honest responding in experimental paradigms. This study examined the incremental utility of eye-tracking on a clinical performance validity test (PVT) in distinguishing adults with verified TBI from adults coached to feign cognitive impairment. METHOD: Participants were 49 adults with moderate-to-severe TBI (TBI), 47 healthy adults coached to simulate TBI (SIM), and 67 healthy comparisons providing full effort (HC). A PVT linked to eye-tracking was completed in the context of a full neuropsychological battery. RESULTS: Kruskal-Wallis tests revealed that eye-tracking indices did not differ among the groups during presentation of stimulus items but did differ during forced-choice trials. Compared to TBI and HC, SIM had significantly more transitions, fixations, and time spent looking at correct and incorrect response options. Logistic regressions and ROC curve analyses showed that accuracy was the best predictor of SIM versus HC. For SIM versus TBI, eye-tracking indices exceeded accuracy in distinguishing the groups. Eye-tracking added incremental predictive value to accuracy for both SIM-HC and SIM-TBI discriminations. CONCLUSION: Eye-tracking indicated that persons feigning TBI showed multiple signs of greater cognitive effort than persons with verified TBI and healthy comparisons. In the comparison of greatest interest (SIM vs. TBI) eye-tracking best predicted group status and yielded excellent discrimination when combined with accuracy. Eye-tracking may be an important complement to traditional accuracy scores on PVTs. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Resilience and well-being after traumatic brain injury.

Purpose: This study examined the extent to which resilience is associated with well-being outcomes after traumatic brain injury, and whether those relationships are independent of global personality traits, such as affectivity.Materials and methods: Sixty-seven adults with complicated-mild to severe traumatic brain injury participated. Measures included the Connor-Davidson Resilience Scale, Modified Cumulative Illness Rating Scale, Disability Rating Scale, SF-12 Health Survey, Satisfaction with Life Scale, and Community Integration Measure.Results: Objective physical health and disability showed modest relation to resilience, indicating that adverse health conditions and disability decreased with increasing resilience. The three measures of subjective well-being showed modest-to-strong positive relation to resilience. These correlations between resilience and well-being generally remained significant after accounting for negative and positive affectivity. Results also suggest that the influence of resilience on well-being has a threshold effect: a greater influence on outcome among people with low or inadequate resilience than among people with average or high resilience.Conclusion: The experience of brain injury does not diminish the positive influence resilience may have on long-term well-being. Resilience may function as a buffer to trauma even in the challenging context of cognitive insult. Routine assessment of resilience might be beneficial to the rehabilitation team.Implications for rehabilitationResilience is positively associated with subjective and objective well-being among adults with moderate-to-severe traumatic brain injury, and it appears to function among adults with traumatic brain injury similarly to adults without cognitive disabilities.Resilience overlaps with overarching trait personality constructs such as affectivity; yet, it has unique characteristics and unique value in understanding well-being.The adverse effects of low resilience show stronger influence on well-being than do the positive effects of high resilience.Routine assessment of resilience might be beneficial to the rehabilitation team in understanding patients and their families, especially in discharge planning, where beliefs about personal capabilities to rebound from adversity shape likely future behavior.

Characteristics of Adults With Unrecognized Hearing Loss.

Purpose Early detection of hearing loss is important for providing support and intervention for adults with age-related hearing loss. However, many older adults have hearing loss that is unidentified. Because they do not present the problem at health care settings, there is a dearth of research on people with unrecognized hearing loss (URHL). This study elucidates differences between older adults with normal hearing, adults with recognized hearing loss (RHL), and adults with URHL. Method Participants included 130 adults, ages 55-85 years. Of these, 39 had hearing in the normal range (HNR), 61 had RHL, and 30 reported HNR but failed a hearing screen (i.e., URHL). Participants completed the Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988 ) and a battery of neuropsychological tests. Results The URHL group reported more positive affectivity than the HNR and RHL groups on the PANAS. In addition, the URHL group was significantly older and more likely to be male compared to the HNR group. Importantly, age was not significantly correlated with PANAS. Positive affectivity accounted for unique variance in group membership even after accounting for age, gender, physical health, and cognitive health. Conclusions Older adults with URHL have more positive affectivity than older adults with HNR or RHL. This group may be prone to downplaying their difficulties; consequently, they may need to experience larger hearing deficits before seeking help. The findings highlight the need for research investigating the effectiveness of psychoeducation on the importance of formal hearing assessment verses relying on self-assessment in facilitating early and effective intervention among people with URHL.
