A SHORT-TERM LONGITUDINAL STUDY ON MULTIDIMENSIONAL OUTCOMES FOLLOWING MILD TRAUMATIC BRAIN INJURY IN MULTI-ETHNIC MALAYSIA

This is a short-term longitudinal study of physical, cognitive, psychological and functional outcomes following mild traumatic brain injury (mTBI) in adults, caused by road traffic accident (RTA). Outcome measures were the Montreal Cognitive Assessment (MoCA), the Neuropsychological Assessment Battery Screening Module (S-NAB), the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder 7 (GAD-7) scale. Functional outcomes included returning to working/academia and driving, lifestyle changes, financial claims and litigation status. A total of 285 individuals were diagnosed with mTBI, involving young male motorcyclists (90%): uncomplicated mTBI, n=201; complicated mTBI, n=84. Ethnic distribution consisted of 204 Malays, 58 Indians and 23 Chinese. MoCA detected cognitive deficits (mean=23.11, SD=3.41) within 72 hours of injury. At two weeks, somatic manifestations, physical injuries, cognitive deficits and psychological symptoms were detected. At three months of injury, the language domain was persistently impaired, with a lower score on most cognitive domains in the complicated mTBI category than the uncomplicated mTBI. Psychological and somatic symptoms had improved. Almost 50% of patients had returned to a functional baseline within two weeks of injury and a further 24% within three months. A small proportion of patients made active lifestyle changes (<25%), financial injury claims (38%) and were involved in litigation (11%). In conclusion, mTBI in multi-ethnic Malaysia has multifaceted deficits and outcomes. Early management of symptoms may promote maximum recovery.

The neuropsychological assessment battery (NAB) is a valuable tool for evaluating neuropsychological outcome after aneurysmatic subarachnoid hemorrhage

BackgroundDetecting and treating neuropsychological deficits after aneurysmatic subarachnoid hemorrhage (aSAH) play a key role in regaining independence; however, detecting deficits relevant to social and professional reintegration has been difficult and optimal timing of assessments remains unclear. Therefore, we evaluated the feasibility of administering the Neuropsychological Assessment Battery screening module (NAB-S) to patients with aSAH, assessed its value in predicting the ability to return to work and characterized clinical as well as neuropsychological recovery over the period of 24 months.MethodsA total of 104 consecutive patients treated for aSAH were recruited. After acute treatment, follow up visits were conducted at 3, 12 and 24 months after the hemorrhage. NAB-S, Montreal Cognitive Assessment (MoCA) and physical examination were performed at each follow up visit.ResultsThe NAB-S could be administered to 64.9, 75.9 and 88.9% of the patients at 3, 12 and 24 months, respectively. Moderate impairment of two or more neuropsychological domains (e.g speech, executive function, etc.) significantly correlated with inability to return to work at 12 and 24 months as well as poor outcome assessed by the extended Glasgow Outcome Scale (GOSE) at 3, 12 and 24 months. The number of patients with favorable outcomes significantly increased from 25.5% at discharge to 56.5 and 57.1% at 3 and 12 months, respectively, and further increased to 74.1% after 24 months.ConclusionThe NAB-S can be administered to the majority of patients with aSAH and can effectively detect clinically relevant neuropsychological deficits. Clinical recovery after aSAH continues for at least 24 months after the hemorrhage which should be considered in the design of future clinical trials.

Validation of the Neuropsychological Assessment Battery Screening Module (NAB-SM) in patients with traumatic brain injury

This study cross-validates the screening module of the Neuropsychological Assessment Battery (NAB-SM) with a battery of well validated neuropsychological tests (Convergent Validity Test Battery: CVTB) in a Traumatic Brain Injury (TBI) population. Forty-four participants with “mild-complicated” to “severe” TBI were recruited from a cohort of patients attending an outpatient clinic at a UK major trauma center. The NAB-SM Total Index score and an abbreviated short-form, from which a TBI Index was derived, both showed good classification accuracy in predicting impairment as measured by the CVTB mean score. These indices also accurately identified impairment as defined by the base rate of low scores across individual CVTB indices measuring mental processing speed, working memory, memory and executive functioning. The NAB-SM and its derived TBI index therefore have significant utility as a cognitive screening tool for use in either inpatient (acute) or outpatient TBI populations.

S75. PERFORMANCE IN WORKING MEMORY AND EXECUTIVE FUNCTIONS AS IT RELATES TO THEORY OF MIND ABILITIES IN A NONCLINICAL SAMPLE OF INDIVIDUALS WITH SCHIZOTYPAL TRAITS

BackgroundIn recent decades, research in the treatment of schizophrenia has shifted to early detection and intervention. Unfortunately, the development of psychosis is still poorly understood, making such an endeavour more challenging. Cognitive models of psychosis suggest that neurocognitive deficits place an individual at greater risk of developing metacognitive deficits. Such deficits in metacognition have been shown to contribute to the development of positive symptomatology. A large body of literature supports that patients with schizophrenia exhibit impairments across nearly all domains of neurocognition, as well as metacognition. Theory of mind (ToM) is one of the most widely studied components of metacognition, which includes both cognitive (i.e., understanding what another person is thinking) and affective (i.e., understanding what another person is feeling) processes. Research indicates patients with schizophrenia demonstrate deficits in cognitive and affective ToM, and these deficits are associated with delusional symptomatology. If ToM is involved in the development of positive symptoms, it is expected that this deficit would be present prior to the onset of a first episode psychosis. It is unclear from current research findings if this is the case, however. Additionally, research examining the role of neurocognition as it relates to ToM is lacking. While some research has examined these variables in clinically-high-risk (CHR) groups, little research has examined nonclinical samples at risk for psychosis. Thus, this study sought to examine the relationship between ToM and neurocognition in a nonclinical sample with schizotypal traits, as research suggests these individuals may be at risk of developing a psychotic illness. It was hypothesized that lower performance in working memory and executive functioning would be related to poorer performance in cognitive and affective ToM, which would subsequently be associated with subsyndromal delusions. It was further predicted that schizotypal traits would moderate the relationship between neurocognitive performance and ToM abilities.MethodsUndergraduate students (N = 99) completed self-report measures of personality and psychosocial functioning, including the Schizotypal Personality Questionnaire, Beck Depression Inventory-II, Launay-Slade Hallucination Scale-Revised, and 21-Item Peters Delusions Inventory. Participants also completed the Neuropsychological Assessment Battery Screening Module, which is a screening measure for neurocognitive dysfunction. Finally, they completed the Recognition of Faux Pas Test, a task-based measure that evaluates cognitive and affective ToM.ResultsData collection is complete, and the data will be analysed using partial least squares structural equation modeling. This is a regression-based path analysis designed for exploratory models. This statistical method is better able to handle non-normally distributed data and smaller sample sizes when compared to covariance-based structural equation modeling.DiscussionStudy findings will be discussed in the context of cognitive models for the development of psychosis. The ways in which these findings, and cognitive models more broadly, can facilitate early detection of schizophrenia will be discussed, along with how such models can be used to inform psychosocial interventions for the illness.

Validity and reliability of the Neuropsychological Assessment Battery – Screening Module (S-NAB) in a subset of Malaysian population with mild traumatic brain injury (mTBI)

This study assessed the validity (construct validity) and reliability (internal consistency) of the Neuropsychological Assessment Battery Screening Module (S-NAB) in detecting mild cognitive deficit/alteration in multicultural, multilingual, and multiethnic mild traumatic brain injury (mTBI) population of Malaysia. S-NAB and Montreal Cognitive Assessment (MoCA) data from 114 patients with mTBI (93 males; 21 females) aged 18 to 60 years old were obtained at University Malaya Medical Center, Malaysia. The mean age was 28.17 ± 8.57 years and mean education years was 12.40 ± 2.01. Convergent validity was assessed between S-NAB domain scores and MoCA total scores by using Pearson’s correlation and internal consistency was assessed using Cronbach’s alpha. Acceptable internal consistency (α ≥ .70) was found for Attention, Language, and Memory domains but weak internal consistencies (α < .50) were found for Spatial and Executive Function domains. There were positive but weak correlations between S-NAB and MoCA. These findings provide some support for the application of S-NAB in assessing mild cognitive deficits of mTBI population in a Malaysian setting.

A-72 Cross Validation of the Automated Neuropsychological Assessment Metrics (ANAM) Performance Validity Measure in Active Duty Service Members

Abstract Objective The Automated Neuropsychological Assessment Metrics (ANAM) is the currently mandated Neurocognitive Assessment Tool (NCAT) for the Department of Defense for pre-deployment baseline testing and is the recommended tool for post-concussion evaluation and return to duty decision making. An ANAM performance validity measure has undergone initial validation (Roebuck-Spencer, Vincent, Gilliland, Johnson and Cooper, 2013). However, cross validation in other samples is warranted, particularly in order to establish cut-points for utilization in the evaluation of mTBI/concussion. The current study retrospectively examined the operating characteristics of the ANAM PVI relative to a more established performance validity test (PVT) in a sample of active duty Service Members referred for neurocognitive screening postconcussion in an Army brain injury clinic. Method Retrospective review of 172 US Service Members referred for neurocognitive screen for possible mild traumatic brain injury/concussion on average 3.8 years post injury (range = 8 days to 27 years) and administered the ANAM, Word Memory Test (WMT), and Neuropsychological Assessment Battery Screening Module (NAB-S). Results Utilizing the WMT as the criterion measure, ROC analysis was significant with AUC = 0.894 (p &lt; 0.001). At 90.09% specificity (95% CI = 83.0% - 94.9%), the optimal cut-point was ANAM PVM ≥ 6, and resulted in 67.21% sensitivity (95% CI = 54.0% - 78.7%). Conclusions The standard ANAM PVI clinical report utilizes a cut-point of 14; however, the current data indicate a cut-point of ≥ 6 may be better suited for patients with mTBI/concussion.

Predictive Validity of the Neuropsychological Assessment Battery-Screening Module for Assessing Real-World Disability in Patients with Mild Traumatic Brain Injury

The present study set out to examine the ecological validity of the Neuropsychological Assessment Battery-Screening Module (NAB-S) and to examine more specifically, whether performance on this test battery is related to real-world disability status in patients who have sustained a mild traumatic brain injury (mTBI) as a consequence of a motor vehicle collision (MVC). Seventy-nine patients were recruited from a random sample of litigating patients who incurred an mTBI and were referred for a neuropsychological examination due to subjective complaints of cognitive function. Of the total sample, 54 patients were categorized into the non-disabled group and 25 patients were categorized into the disabled group using the 4th edition of the American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment (AMA; 1993). A multivariate analysis of variance revealed that performance on the NAB-S significantly differed between the two groups, and that memory and attention domains provided a more discriminative index of disability than general neuropsychological functions. In addition, discriminant function analyses revealed that the NAB-S correctly classified 73% of patients according to their group membership. The current findings provide evidence for the ecological validity of the NAB-S as a reliable index of real-world disability status as defined by the AMA Guides.

The Development and Psychometric Evaluation of a Supplementary Index Score of the Neuropsychological Assessment Battery Screening Module that is Sensitive to Traumatic Brain Injury.

This study examines the validity of the NAB Screening Module (screening module of the neuropsychological assessment battery, S-NAB) in an acute traumatic brain injury (TBI) inpatient population and provides psychometric evaluation of an original index sensitive to TBI impairment. The utility of the S-NAB as a TBI screen was examined using a between groups design. One-hundred and four patients with mild complicated to severe TBI were recruited from a consecutive cohort of patients admitted as inpatients to a UK Major Trauma Centre. Ninety-eight control participants were selected from the S-NAB normative sample. All TBI patients completed the S-NAB during their inpatient stay. Control participants scored significantly higher than TBI participants on the Total Screening index (t=3.626, p<0.01), The Attention index (t=7.882, p<0.01), and the Executive index (t=5.577, p<0.01). A briefer TBI Impairment index of six subtests was constructed which accurately discriminated TBI patients from normative controls (t=9.9, p<0.01; Cohen's d=1.54). The TBI index had excellent classification accuracy (AUC=0.83), superior to that of the standard S-NAB indices. The TBI Index, Attention Index, and Total Screening Index demonstrated increasing impairment with increased severity of injury. The S-NAB TBI index is a robust, reliable screening index for use with acute TBI patients, which is sensitive to the effects of acute TBI. It affords a briefer cognitive screen than the S-NAB and demonstrates a dose response relationship to TBI severity.

Performance validity test and neuropsychological assessment battery screening module performances in an active-duty sample with a history of concussion

ABSTRACTThe current retrospective investigation sought to replicate previous findings demonstrating the significant impact of performance validity test (PVT) performance and evaluation context on neuropsychological testing. We examined differences on performance validity testing between active-duty service members undergoing neurocognitive screening for concussion who were seen in a clinical context and those who were seen in a disability-seeking context, as well as the overall impact of PVT performance on a neurocognitive screening battery. Overall, 38.2% of the sample failed the Word Memory Test (WMT). Of those involved in a disability evaluation, the failure rate was 51.9%, which was significantly higher than the 36.8% failure rate among those evaluated in a clinical context. The effect size of WMT performance on a cognitive screening measure was also large. The current retrospective analysis served to replicate previous work.

C-34 * Does a Dose-Response Relationship Exist between Traumatic Brain Injury Severity and Outcome in a Compensation Setting?

Objective: Research has suggested that traumatic brain injury (TBI) severity is one of the most robust predictors of outcome following a TBI, yet there have been few investigations within a compensation setting. The current study examined whether a similar dose-response relationship between severity and neuropsychological and psychological outcomes exists in a litigation sample with credible neuropsychological test scores. Method: Participants (n = 66) referred for compensation-related reasons following a TBI were retrospectively categorized as mild complicated-moderate (n = 39) or severe (n = 27) based on their Glasgow Coma Scale ratings and neuroimaging findings. Participants with a history of psychiatric and neurological conditions or failure on multiple standardized performance validity tests were excluded. Participants completed the Neuropsychological Assessment Battery – Screening Module (NAB-SM), Beck Depression Inventory II (BDI-II), and Beck Anxiety Inventory (BAI). Age- and educated-adjusted norms were used. Results: Hierarchical regression analysis revealed that injury severity did not significantly predict overall NAB-SM scores (R2 = .01, F(1, 64) = .62, p = .43) or any of the domains. However, severity was a significant predictor of BDI-II (R2 = .13, F(1, 42) = 6.04, p = .02) and BAI scores (R2 = .20, F(1, 42) = 10.45, p < .01), with higher levels of depression and anxiety endorsed for mild complicated-moderate TBI than severe TBI groups. Conclusion(s): Individuals with less severe injuries examined in a compensation setting endorsed more emotional symptoms, but TBI severity was not predictive of neuropsychological performance in a litigation population.

Neuropsychological Assessment Battery-Screening Module (S-NAB): Performance in treatment-seeking cocaine users

Background: Cocaine use is associated with cognitive impairments, which can have a negative effect on treatment retention and drug use. Thus, there is an increasing demand for a screening cognitive battery can be used by clinicians to detect such impairments in cocaine patients so that treatment can be adapted to patients’ specific cognitive strengths and deficits. The Neuropsychological Assessment Battery-Screening Module (S-NAB) test for adults takes approximately 35–45 min to administer, and assesses attention, language, memory (verbal and visual), visual spatial reasoning, and executive functioning. Objective: The purpose of this descriptive study was to present S-NAB score results for a sample of treatment seeking adult cocaine users to determine its potential utility for detecting cognitive impairments in this population. Methods: In the present sample, 145 adult cocaine users participated in screening to enroll in an intervention to decrease cocaine use (59% male; 73.1% African American); screening included the S-NAB and self-report questionnaires. Results: A substantial proportion of the sample (44%) met criteria for impairment, i.e. composite scores of one or more standard deviations below the mean. Furthermore, memory scores were significantly lower than language and spatial scores (p < 0.007). Conclusions: The impairments detected by the S-NAB were generally consistent with those previously observed in samples of cocaine users completing other batteries, as well in other substance abusing samples completing the S-NAB. This suggests that the S-NAB can be considered an additional appropriate battery, as an alternative to other existing batteries, for assessment of the cognitive functioning of adult cocaine users.

Ecological validity of the screening module and the Daily Living tests of the Neuropsychological Assessment Battery using the Mayo-Portland Adaptability Inventory-4 in postacute brain injury rehabilitation.

The assessment of ecological validity of neuropsychological measures is an area of growing interest, particularly in the postacute brain injury rehabilitation (PABIR) setting, as there is an increasing demand for clinicians to address functional and real-world outcomes. In the current study, we assessed the predictive value of the Screening module and the Daily Living tests of the Neuropsychological Assessment Battery (NAB) using clinician ratings from the Mayo-Portland Adaptability Inventory-4 (MPAI-4) in patients with moderate to severe traumatic brain injury. Forty-seven individuals were each administered the NAB Screening module (NAB-SM) and the NAB Daily Living (NAB-DL) tests following admission to a residential PABIR program. MPAI-4 ratings were also obtained at admission. Linear regression analysis was used to examine the association between these functional and neuropsychological assessment measures. We replicated prior work (Temple at al., 2009) and expanded evidence for the ecological validity of the NAB-SM. Furthermore, our findings support the ecological validity of the NAB-DL Bill Payment, Judgment, and Map Reading tests with regards to functional skills and real-world activities. The current study supports prior work from our lab assessing the predictive value of the NAB-SM, as well as provides evidence for the ecological validity for select NAB-DL tests in patients with moderate to severe traumatic brain injury admitted to a residential PABIR program.

Validity of the Montreal Cognitive Assessment (MoCA) as a Screening Test for Mild Cognitive Impairment (MCI) in a Cardiovascular Population

While rates of mild cognitive impairment (MCI) are relatively high in populations with cardiovascular diseases and risk factors, screening tests for MCI have not been evaluated in this patient group. This study investigated the sensitivity and specificity of the Montreal Cognitive Assessment (MoCA) tool for detecting MCI in 110 patients (mean age 67.9 + 11.7 years; 60% female) recruited from hospital cardiovascular outpatient clinics. Mean MoCA performance was relatively low (22.8 + 3.8) in this group, with 72.1% of participants scoring below the recommended cutoff for cognitive impairment (<26). The presence of MCI was determined using the Neuropsychological Assessment Battery Screening Module (NAB-SM). Both amnestic MCI and multiple-domain MCI were identified. The optimum MoCA cutoff for detecting MCI in this group was <24. At this cutoff, the MoCA's sensitivity for detecting amnestic MCI was 100% and for multiple-domain MCI it was 83.3%. Specificity rates for amnestic MCI and multiple-domain MCI were 50.0% and 52% respectively. The poor specificity of the MoCA suggests that it will have limited value as a screening test for MCI in settings where the overall prevalence of MCI is low.

Neuropsychological Assessment Battery (NAB): Performance in a Sample of Patients with Moderate-to-Severe Traumatic Brain Injury

The Neuropsychological Assessment Battery (NAB; Stern & White, 2003) is a comprehensive test battery that assesses five cognitive domains (Attention, Language, Memory, Spatial, and Executive Functions). The purpose of the current descriptive study was to present data on the index and primary test scores from the five main NAB cognitive modules in a sample of patients with moderate-to-severe traumatic brain injury (TBI) admitted to a residential postacute rehabilitation program. Twenty patients were administered all five main NAB modules upon recommendation from the NAB Screening module. The sample performed significantly worse than normal on tests that assess selective and divided attention, psychomotor speed, verbal memory, and cognitive flexibility. The largest proportion of patients performing below an established impairment cutoff (10th percentile) occurred on the Numbers and Letters, List Learning, Story Learning, Daily Living Memory, and Categories Tests. Significant performance decrements were not observed on any indices or tests from the Language or Spatial cognitive domain modules. The pattern of performance on the NAB demonstrated by the current sample is consistent with the neuropsychological profile observed in postacute patients with moderate-to-severe TBI without focal deficits (e.g., aphasia), demonstrating its relative sensitivity in this patient population. A comparison between the current study sample and a related clinical sample from the NAB standardization data is discussed.

Influence of poor effort on self-reported symptoms and neurocognitive test performance following mild traumatic brain injury

When considering a diagnosis of postconcussion syndrome, clinicians must systematically evaluate and eliminate the possible contribution of many differential diagnoses, comorbidities, and factors that may cause or maintain self-reported symptoms long after mild traumatic brain injury (MTBI). One potentially significant contributing factor is symptom exaggeration. The purpose of the study is to examine the influence of poor effort on self-reported symptoms (postconcussion symptoms and cognitive complaints) and neurocognitive test performance following MTBI. The MTBI sample consisted of 63 referrals to a concussion clinic, evaluated within 5 months post injury (M = 2.0, SD = 1.0, range = 0.6–4.6), who were receiving financial compensation from the Workers' Compensation Board. Participants completed the Post-Concussion Scale (PCS), British Columbia Cognitive Complaints Inventory (BC-CCI), selected tests from the Neuropsychological Assessment Battery Screening Module (S-NAB), and the Test of Memory Malingering (TOMM). Participants were divided into two groups based on TOMM performance (15 fail, 48 pass). There were significant main effects and large effect sizes for the PCS (p = .002, d = 0.79) and BC-CCI (p = .011, d = 0.98) total scores. Patients in the TOMM fail group scored higher than those in the TOMM pass group on both measures. Similarly, there were significant main effects and/or large effect sizes on the S-NAB. Patients in the TOMM fail group performed more poorly on the Attention (p = .004, d = 1.26), Memory (p = .006, d = 1.16), and Executive Functioning (p > .05, d = 0.70) indexes. These results highlight the importance of considering the influence of poor effort, in conjunction with a growing list of factors that can influence, maintain, and/or mimic the persistent postconcussion syndrome.

Reliability and Validity of the Neuropsychological Assessment Battery-Screening Module (NAB-SM) in a Sample of Patients with Moderate-to-Severe Acquired Brain Injury

The Screening module from the Neuropsychological Assessment Battery (NAB-SM; Stern & White, 2003) is a comprehensive cognitive screening measure that assesses five domains (Attention, Language, Memory, Spatial, and Executive Functions). The construct validity of the NAB-SM in comparison to established neuropsychological (NP) measures in individuals with moderate-to-severe brain injury has yet to be investigated. Participants were 42 individuals with acquired brain injury admitted to a post-acute residential rehabilitation program. The NAB-SM cognitive domain index scores demonstrated weak internal consistency, whereas internal consistency for the NAB-SM total index score was satisfactory. In demonstrating construct validity, the NAB-SM cognitive domain index scores and individual subtest scores maintained several significant relationships with other NP tests that shared test structure and content or not. These relationships were limited or absent for the NAB-SM Executive Functions subtests and the NAB-SM Shape Learning subtest. Our findings provide preliminary support for the reliability and validity of the NAB-SM in a sample of patients with moderate-to-severe brain injury.

Ecological validity of the neuropsychological assessment battery screening module in post-acute brain injury rehabilitation

Primary objective: To assess the ecological validity of the Screening Module of the Neuropsychological Assessment Battery (NAB-SM) using the Functional Independence Measure (FIM).Method: Seventy individuals with moderate-to-severe traumatic brain injury at a residential post-acute rehabilitation facility were administered the FIM instrument and the NAB-SM upon admission. Hierarchical regression analysis was used to examine the relationship between the variables from these two assessment measures.Results: Hierarchical models revealed that (1) the NAB-SM Total score was significantly associated with the FIM instrument Total score as well as the Motor and Cognition sub-scale scores, above and beyond the contribution of demographic variables, (2) the NAB-SM Language, Memory and Spatial domain scores were significantly associated with of the FIM instrument Cognition sub-scale score and (3) the NAB-SM Spatial domain score was significantly associated with of the FIM instrument Total and Motor sub-scale scores.Conclusions: The current findings support previous research and provide strong evidence for the ecological validity of the NAB-SM with regard to functional abilities as assessed by the FIM instrument.

Rapid cognitive screening of patients with substance use disorders.

To date, there has not been a time-efficient and resource-conscious way to identify cognitive impairment in patients with substance use disorders (SUDs). In this study, we assessed the validity, accuracy, and clinical utility of a brief (10-min) screening instrument, the Montreal Cognitive Assessment (MoCA), in identifying cognitive impairment among patients with SUDs. The Neuropsychological Assessment Battery-Screening Module, a 45-min battery with known sensitivity to the mild to moderate deficits observed in patients with SUDs, was used as the reference criterion for determining agreement, rates of correct and incorrect decision classifications, and criterion-related validity for the MoCA. Classification accuracy of the MoCA, based on receiver operating characteristic (ROC) analysis, was strong, with an area under the ROC curve of 0.86, 95% confidence interval [0.75, 0.97]. The MoCA also showed acceptable sensitivity (83.3%) and specificity (72.9%) for the identification of cognitive impairment. Using a cutoff of 25 on the MoCA, the overall agreement was 75.0%; chance-corrected agreement (kappa) was 41.9%. These findings indicate that the MoCA provides a time-efficient and resource-conscious way to identify patients with SUDs and neuropsychological impairment, thus addressing a critical need in the addiction treatment research community.
