RESUMEN
Objective: Performance below the actual abilities of the examinee can be measured using performance validity tests (PVTs). PVT failure negatively impacts the quality of the neuropsychological assessment. In our study, we addressed this issue by providing a brief corrective statement regarding invalidity to improve test-taking behavior. Methods: This study is a multisite single-blind randomized controlled trial in a consecutive sample of clinically referred adult patients (N = 196) in a general hospital setting. Patients who failed a PVT (n = 71) were randomly allocated to a corrective statement approach (CS; n = 39), in which a brief verbal corrective statement was given by the technician, or received no corrective statement upon indications of invalid performance (NO-CS; n = 32). Both groups (CS and NO-CS) were provided with the same subsequently repeated and newly administered tests. Results: There were no group (CS vs. NO-CS) differences on both the repeated and single-administered PVTs and standard cognitive tests. Furthermore, invalid performing participants benefited significantly less from the repeated test administration compared to the valid performing group. Conclusions: Our study found that a brief corrective within-session statement, to address PVT failure and improve test-taking behavior, did not improve consequent test performance. These results suggest limited value of a brief verbal corrective statement to influence performance below best of capabilities. It highlights the need for more research to identify more effective approaches that can enhance patients test-taking behavior. Ultimately, such efforts are critical in ensuring accurate diagnosis and effective treatment recommendations for patients.
RESUMEN
INTRODUCTION: The use of performance validity tests (PVTs) in a neuropsychological assessment to determine indications of invalid performance has been a common practice for over a decade. Most PVTs are memory-based; therefore, the Groningen Effort Test (GET), a non-memory-based PVT, has been developed. OBJECTIVES: This study aimed to validate the GET in patients with suspected chronic solvent-induced encephalopathy (CSE) using the criterion standard of 2PVTs. A second goal was to determine diagnostic accuracy for GET. METHOD: Sixty patients with suspected CSE referred for NPA were included. The GET was compared to the criterion standard of 2PVTs based on the Test of Memory Malingering and the Amsterdam Short Term Memory Test. RESULTS: The frequency of invalid performance using the GET was significantly higher compared to the criterion of 2PVTs (51.7% vs. 20.0% respectively; p < 0.001). For the GET index, the sensitivity was 75% and the specificity was 54%, with a Youden's Index of 27. CONCLUSION: The GET showed significantly more invalid performance compared to the 2PVTs criterion suggesting a high number of false positives. The general accepted minimum norm of specificity for PVTs of >90% was not met. Therefore, the GET is of limited use in clinical practice with suspected CSE patients.
RESUMEN
INTRODUCTION: Follow-up care after treatment for colorectal cancer (CRC) is increasingly focused on health-related quality of life (HRQoL) and functional outcomes. The Assessment of Burden of ColoRectal Cancer (ABCRC)-tool is developed to measure these outcomes and support patient-oriented care. The tool comprises items assessing burden of disease and lifestyle parameters. It consists of a generic module combined with one of the three CRC specific modules. The objective of this study is to assess the construct validity and reliability of the items of the ABCRC-tool. METHODS: Patients who were receiving follow-up care after surgical CRC treatment were invited to complete the ABCRC-tool together with other validated patient-reported outcome measures (PROMs). Construct validity was assessed by testing expected correlations between items of the ABCRC-tool and domains of other PROMs and by examining predefined hypotheses regarding differences in subgroups of patients. Patients completed the ABCRC-tool twice, with 8 days apart, to evaluate its reliability. RESULTS: In total, 177 patients participated (64% male) with a mean age of 67 years (range 33-88). The colon, rectum and stoma module were completed by subsequently 89, 53 and 35 patients. Most items correlated as expected with anticipated domains of the EORTC QLQ-C30 or EORTC QLQ-CR29 (all p-values <0.05). Furthermore, the ABCRC-tool could discriminate between subgroups of patients. The intraclass correlation coefficient (ICC) was good (>0.70) for most items, indicating good reliability. CONCLUSION: The ABCRC-tool is a valid and reliable instrument that is ready for use in a clinical setting to support personalized follow-up care after CRC treatment.

OBJECTIVE: We investigated how well a visual associative learning task discriminates Alzheimer's disease (AD) dementia from other types of dementia and how it relates to AD pathology. METHODS: 3,599 patients (63.9 ± 8.9 years old, 41% female) from the Amsterdam Dementia Cohort completed two sets of the Visual Association Test (VAT) in a single test session and underwent magnetic resonance imaging. We performed receiver operating curve analysis to investigate the VAT's discriminatory ability between AD dementia and other diagnoses and compared it to that of other episodic memory tests. We tested associations between VAT performance and medial temporal lobe atrophy (MTA), and amyloid status (n = 2,769, 77%). RESULTS: Patients with AD dementia performed worse on the VAT than all other patients. The VAT discriminated well between AD and other types of dementia (area under the curve range 0.70-0.86), better than other episodic memory tests. Six-hundred forty patients (17.8%) learned all associations on VAT-A, but not on VAT-B, and they were more likely to have higher MTA scores (odds ratios range 1.63 (MTA 0.5) through 5.13 for MTA ≥ 3, all p < .001) and to be amyloid positive (odds ratio = 3.38, 95%CI = [2.71, 4.22], p < .001) than patients who learned all associations on both sets. CONCLUSIONS: Performance on the VAT, especially on a second set administered immediately after the first, discriminates AD from other types of dementia and is associated with MTA and amyloid positivity. The VAT might be a useful, simple tool to assess early episodic memory deficits in the presence of AD pathology.
RESUMEN
BACKGROUND: Cognitive problems contribute to decline in work performance. We evaluated (1) the effectiveness of basic self-management and extensive therapist-guided online cognitive rehabilitation on attainment of individually predetermined work-related goals among occupationally active cancer survivors, and (2) whether effectiveness of the programs differed for survivors with and without formal cognitive impairment. METHODS: In a 3-arm randomized controlled trial (NCT03900806), 279 non-central nervous system cancer survivors with cognitive complaints were assigned to the basic program (n = 93), the extensive program (n = 93), or a waiting-list control group (n = 93). Participants completed measurements pre-randomization (T0), 12 weeks post-randomization upon program completion (T1), and 26 weeks post-randomization (T2). Mixed-effects modeling was used to compare intervention groups with the control group on goal attainment, and on self-perceived cognitive problems, work ability, and health-related quality of life. RESULTS: Participants in the extensive program achieved their predetermined goals better than those in the control group, at short- and long-term follow-up (effect size [ES] = .49; P < .001; ES = .34; P = .014). They also had fewer recovery needs after work (ES = -.21; P = .011), more vitality (ES = .20; P = .018), and better physical role functioning (ES = .0.43 P = .015) than controls. At long-term follow-up, this finding persisted for physical role functioning (ES = .42; P = .034). The basic program elicited a small positive nonsignificant short-term (not long-term) effect on goal attainment for those with adequate adherence (ES = .28, P = .053). Effectiveness of the programs did not differ for patients with or without cognitive impairment. CONCLUSIONS: Internet-based therapist-guided extensive cognitive rehabilitation improves work-related goal attainment. Considering the prevalence of cognitive problems in survivors, it is desirable to implement this program.

Performance validity tests (PVTs) are used to measure the validity of the obtained neuropsychological test data. However, when an individual fails a PVT, the likelihood that failure truly reflects invalid performance (i.e., the positive predictive value) depends on the base rate in the context in which the assessment takes place. Therefore, accurate base rate information is needed to guide interpretation of PVT performance. This systematic review and meta-analysis examined the base rate of PVT failure in the clinical population (PROSPERO number: CRD42020164128). PubMed/MEDLINE, Web of Science, and PsychINFO were searched to identify articles published up to November 5, 2021. Main eligibility criteria were a clinical evaluation context and utilization of stand-alone and well-validated PVTs. Of the 457 articles scrutinized for eligibility, 47 were selected for systematic review and meta-analyses. Pooled base rate of PVT failure for all included studies was 16%, 95% CI [14, 19]. High heterogeneity existed among these studies (Cochran's Q = 697.97, p < .001; I2 = 91%; τ2 = 0.08). Subgroup analysis indicated that pooled PVT failure rates varied across clinical context, presence of external incentives, clinical diagnosis, and utilized PVT. Our findings can be used for calculating clinically applied statistics (i.e., positive and negative predictive values, and likelihood ratios) to increase the diagnostic accuracy of performance validity determination in clinical evaluation. Future research is necessary with more detailed recruitment procedures and sample descriptions to further improve the accuracy of the base rate of PVT failure in clinical practice.

PURPOSE: To assess cognitive functioning in occupationally active non-central nervous system cancer survivors with cognitive complaints using neuropsychological tests, and to investigate the association between (1) formally assessed cognitive functioning and self-reported work-related outcomes and (2) self-reported cognitive functioning at work and self-reported work-related outcomes. METHODS: Baseline data of a multicenter, randomized controlled trial (n = 279) were used. Associations between neuropsychological test performance (Amsterdam Cognition Scan) and self-reported cognitive functioning (Cognitive Symptom Checklist-work) with work ability (Work Ability Index) and work functioning (Work Role Functioning Questionnaire) were examined using multivariate linear regression. RESULTS: Thirty percent of cancer survivors had lower than expected performance on neuropsychological tests. Higher overall neuropsychological test performance was associated with better work ability (Cohen's f2 = 0.014) and physical functioning at work (Cohen's f2 = 0.13). Furthermore, higher motor performance was associated with better work ability (Cohen's f2 = 0.018). In addition, self-reported work-related cognitive complaints were associated with self-reported work-related outcomes (Cohen's f2 = 0.13-0.35). CONCLUSIONS: The percentage of cancer survivors with lower than expected performance on neuropsychological tests exceeded the percentage expected in a normal population. This neuropsychological test performance was weakly associated with various aspects of work ability and work functioning. Stronger associations were found between self-reported cognitive functioning at work with self-reported work-related outcomes. IMPLICATIONS FOR CANCER SURVIVORS: A cognitive rehabilitation approach that specifically aims at reducing cognitive symptoms at work could be a valuable part of interventions that aim to improve work-related outcomes. Trial registration The study is registered at ClinicalTrials.gov (NCT03900806) at 03 April 2019 (current status: ongoing), https://clinicaltrials.gov/ct2/show/NCT03900806?term=NCT03900806&draw=2&rank=1.
RESUMEN
OBJECTIVE: There is limited research examining the impact of the validity of cognitive test performance on treatment outcome. All known studies to date have operationalized performance validity dichotomously, leading to the loss of predictive information. Using the range of scores on a performance validity test (PVT), we hypothesized that lower performance at baseline was related to a worse treatment outcome following cognitive behavioral therapy (CBT) in patients with Chronic Fatigue Syndrome (CFS) and to lower adherence to treatment. METHOD: Archival data of 1081 outpatients treated with CBT for CFS were used in this study. At baseline, all patients were assessed with a PVT, the Amsterdam Short-Term Memory test (ASTM). Questionnaires assessing fatigue, physical disabilities, psychological distress, and level of functional impairment were administered before and after CBT. RESULTS: Our main hypothesis was not confirmed: the total ASTM score was not significantly associated with outcomes at follow-up. However, patients with a missing follow-up assessment had a lower ASTM performance at baseline, reported higher levels of physical limitations, and completed fewer therapy sessions. CONCLUSIONS: CFS patients who scored low on the ASTM during baseline assessment are more likely to complete fewer therapy sessions and not to complete follow-up assessment, indicative of limited adherence to treatment. However, if these patients were retained in the intervention, their response to CBT for CFS was comparable with subjects who score high on the ASTM. This finding calls for more research to better understand the impact of performance validity on engagement with treatment and outcomes.

INTRODUCTION: Researchers, policy-makers and healthcare professionals often stress the importance of an early dementia diagnosis. Empirical evidence, however, is scarce leading to a lack of consensus on the necessity of diagnosing dementia early. We emphasise the need for a 'timely' diagnosis, that is, one that occurs at the right moment for a person with memory complaints and his/her significant other. As the optimal timing differs between individuals, the implementation of shared decision making (SDM), preferably by the general practitioner (GP), as the start of a diagnostic trajectory, could help to determine this timely moment. SDM, however, is rarely practised with respect to dementia diagnoses. Therefore, in the context of the Shared Decision-Making regarding Dementia Diagnosis project, a patient decision aid (PtDA) for 'timely' dementia diagnosis in general practice will be developed. This protocol will describe the planned before and after evaluation of its implementation. METHODS AND ANALYSIS: In a mixed-methods pilot study, we will investigate decision-making processes and experiences regarding a diagnostic trajectory before and after the introduction of a PtDA for people with memory complaints, their significant others and their GPs. The 'before group' will receive diagnostics as usual from their GPs. The 'after group' will use the PtDA. We expect the PtDA to increase the level of SDM and to contribute to a timely and personalised diagnostic trajectory. Data will be collected using semistructured interviews, questionnaires and information retrieved from people with memory complaints' medical records. ETHICS AND DISSEMINATION: This study protocol was approved by the Medical Review Ethics Committee of the Maastricht University Medical Centre. The findings will be published in peer-reviewed international journals and presented at conferences. This study was funded by the public funded Dutch Research Institute for Care and Medical Sciences (ZonMw). TRIAL REGISTRATION NUMBER: NCT04531956.

Cognitive impairment is frequently reported by silicone breast implant (SBI) patients. The aim of our study is to investigate whether subjective cognitive failure indeed is more frequent in a cohort of SBI patients compared with healthy controls (HCs). Furthermore, the severity of this cognitive failure and a possible relation to other symptoms as well as the duration of SBI exposure was examined. In addition, we assessed the effect of ruptures and reinterventions on cognitive failure severity. METHODS: A cohort study was performed, including 376 women and consisting of 3 different groups of patients; 143 SBI patients (group 1), 94 age- and sex-matched HC patients (group 2), and 139 women with SBI and health issues who registered themselves at a Dutch foundation for women with illness due to SBI (group 3). All patients filled in the Cognitive Failure Questionnaire (CFQ). The American College of Rheumatology Fibromyalgia Diagnostic Criteria (2010) were used to score other symptoms. RESULTS: Completed CFQ data from 222 patients were available for analysis: n = 79 for group 1, n = 62 for group 2, and n = 81 for group 3. SBI patients from group 3 had a significantly higher prevalence of subjective cognitive dysfunction (CFQ score ≥ 43) compared with SBI patients from group 1 and HC (60.5% versus 13.9% and 12.9%; P = 0.000). Linear regression showed a statistically significant relation between subjective cognitive functioning scores and other symptoms (P = 0.000). Implant duration as well as rupture rate and reinterventions were not found to significantly influence CFQ scores. CONCLUSION: An increased risk of cognitive failure in consecutive SBI patients when compared with HCs could not be found.
RESUMEN
OBJECTIVE: To examine the cost-effectiveness of nurse-led stroke aftercare addressing psychosocial outcome at 6 months post stroke, compared with care-as-usual. DESIGN: Economic evaluation within a comparative effectiveness research design. SETTING: Primary care (2016-2017) and community settings (2011-2013) in the Netherlands. PARTICIPANTS: Persons who suffered from ischaemic or haemorrhagic stroke, or a transient ischaemic attack and were discharged home after visiting the emergency department, hospitalisation or inpatient rehabilitation. INTERVENTIONS: Nurse-led stroke aftercare at 6 months post stroke addressing psychosocial functioning by providing screening, psycho-education, emotional support and referral to specialist care when needed. Care-as-usual concerned routine follow-up care including secondary prevention programmes and a consultation with the neurologist at 6 weeks post stroke. PRIMARY AND SECONDARY OUTCOME MEASURES: Main outcome measure of cost-effectiveness was quality-adjusted life years (QALYs) estimated by the quality of life measured by the five-dimensional, three-level EuroQol. Costs were assessed using a cost-questionnaire. Secondary outcomes were mood (Hospital Anxiety and Depression Scale) and social participation (Utrecht Scale for Evaluation of Rehabilitation-Participation) restrictions subscale. RESULTS: Health outcomes were significantly better in stroke aftercare for QALYs (Δ=0.05; 95% CI 0.01 to 0.09) and social participation (Δ=4.91; 95% CI 1.89 to 7.93) compared with care-as-usual. Total societal costs were 1208 higher in stroke aftercare than in care-as-usual (95% CI -3881 to 6057). Healthcare costs were in total 1208 higher in stroke aftercare than in care-as-usual (95% CI -3881 to 6057). Average costs of stroke aftercare were 91 (SD=3.20) per person. Base case cost-effectiveness analyses showed an incremental cost-effectiveness ratio of 24 679 per QALY gained. Probability of stroke aftercare being cost-effective was 64% on a 50 000 willingness-to-pay level. CONCLUSIONS: Nurse-led stroke aftercare addressing psychosocial functioning showed to be a low-cost intervention and is likely to be a cost-effective addition to care-as-usual. It plays an important role by screening and addressing psychosocial problem, not covered by usual care.

BACKGROUND AND PURPOSE: Research suggests comparable long-term psychosocial outcomes following mild traumatic brain injury (mTBI) and minor stroke, but no direct comparison has been made. This study aimed to directly compare psychosocial outcome over time in persons with mTBI and minor stroke. METHODS: In this multicenter, prospective longitudinal cohort study, community-dwelling persons with mTBI (n = 182) and minor stroke (n = 48) were assessed at 6 weeks, 3, 6 and 12 months post-injury. Outcome measures included anxiety and depression symptoms (Hospital Anxiety and Depression Scale-HADS), cognitive problems in daily life (Checklist for Cognitive and Emotional Consequences of Stroke-CLCE-24) and quality of life (EuroQol-5D-5L-EQ-5D-5L). Multilevel growth curve modeling, controlled for demographic variables, was used to determine outcomes over time between groups. Proportions of persons reporting persistent psychosocial symptoms at 6 months post-injury were compared using Pearson's Chi-squared tests. RESULTS: Improvements in outcomes were observed in the first 6 months and effects stabilized to 12 months post-injury in both groups. Minor stroke cases reported significantly higher levels of HADS anxiety and a significantly reduced increase in EQ-5D-5L utility scores than mTBI cases, but differences were small in absolute numbers. No significant differences were observed between groups regarding HADS depression and CLCE-24 cognition scores. Proportions of persons reporting persistent psychosocial symptoms were equal between groups. CONCLUSIONS: Psychosocial outcome is largely comparable following mTBI and minor stroke. Specific attention should be paid to anxiety symptoms and cognitive problems in daily life for which uniform aftercare seems appropriate.

BACKGROUND & AIMS: Cognitive impairment (CI) and metabolic abnormalities, including the metabolic syndrome (MetS) and sarcopenia, are more prevalent in COPD patients compared to controls without diagnosed lung disease. Because earlier studies have shown these metabolic abnormalities may affect cognitive performance, this study investigated whether cognitive performance is more impaired in subgroups of COPD patients with MetS or sarcopenia. METHODS: Cognitive performance patterns of 170 COPD patients referred for pulmonary rehabilitation (53.5% male, 63.4 ± 9.4 years, FEV1 54.5 ± 22.7% predicted) were compared between COPD subgroups stratified by presence of MetS and sarcopenia. Cognitive performance was assessed using a detailed neuropsychological test battery, which measured psychomotor speed (Stroop Color-Word Test, Concept Shifting Test, Letter-Digit Substitution Test), planning (Behavioral Assessment of the Dysexecutive Syndrome), working memory (Visual-Verbal Learning Test, Digit Span), verbal memory (Visual-Verbal Learning Test) and cognitive flexibility (Stroop Color-Word Test, Concept Shifting Test). MetS was determined according to the NCEP ATP-III criteria. Sarcopenia was determined based on decreased appendicular lean mass by dual-energy x-ray absorptiometry and impaired physical performance by 6-min walking distance. RESULTS: MetS was observed in 54.7% and sarcopenia in 30.0% of COPD patients. The prevalence of general CI was not different between patients with and without MetS (30.4% and 39.0%, respectively) or those with and without sarcopenia (34.0% and 34.5%, respectively, both p > 0.05). Domain-specific cognitive performance was not different between metabolic subgroups, but those with sarcopenia displayed a lower prevalence of CI on verbal memory than those without (21.7% and 29.7%, respectively, p = 0.011). Only the digit span (working memory) subtest was significantly different between metabolic subgroups, in favor of those without MetS (p = 0.017). CONCLUSION: Cognitive performance was not affected more in COPD patients with sarcopenia or MetS.

BACKGROUND: Cognitive problems are common in non-central nervous system cancer survivors. These problems are perceived as an important contributor to decline in work performance and work ability. Various interventions for cognitive problems have been proposed, but effectiveness regarding work-related outcomes has not yet been established. Effective treatment options to alleviate the adverse influence of cognitive problems on work performance are needed for working cancer survivors. In this paper, we will describe the design of a randomized, controlled, multicenter trial that evaluates the (cost-)effectiveness of an Internet-based cognitive rehabilitation program for occupationally active cancer survivors confronted with cognitive problems. METHODS/ DESIGN: A three-armed randomized controlled trial will be conducted, including two intervention groups (i.e., basic and extensive cognitive rehabilitation program) and one waitlist control group. In total, 261 cancer survivors (18-65 years) who have returned to work and who experience cognitive problems will be recruited. Patients with and without cognitive impairment as established in a neuropsychological assessment will be eligible; stratification will take place based on the presence of this cognitive impairment. The extensive intervention arm will contain a comprehensive training program (including psycho-education, fatigue management, and cognitive strategy training) with individual guidance (blended intervention). The basic intervention arm will contain a brief cognitive training program (including psycho-education and fatigue management) without individual guidance. The primary outcome will be accomplishment of an individually defined work-related treatment goal. Secondary outcomes include, among others, subjective cognitive functioning, work functioning, and quality of life. Primary and secondary outcomes will be measured at baseline (T0) and at 12 weeks (T1) and 26 weeks (T2) post-randomization. DISCUSSION: About 40-50% of the cancer patients worldwide are of working age at time of diagnosis. Many of the occupationally active cancer survivors experience cognitive problems. Both from an individual and a societal perspective, it is important to sustain cancer survivors' employability. An effective treatment to alleviate the impact of cognitive decline and to improve work ability might help cancer survivors to sustain employability.

PURPOSE: Cancer-related cognitive problems (cancer-related cognitive problems) in working cancer survivors are found to affect work outcomes. We aimed to generate in-depth information regarding cancer-related cognitive problems in working cancer survivors, strategies used to cope with cancer-related cognitive problems at work, and needs of cancer survivors and professionals regarding cancer-related cognitive problems at work. METHODS: Five focus groups were formed, amongst which three focus groups with cancer survivors (n = 8, n = 7, and n = 8) and two focus groups with professionals (n = 7, n = 8). Thematic analysis of the transcripts was performed to create concepts. RESULTS: Both cancer survivors and professionals confirmed that cancer-related cognitive problems, which occurred in several domains of neurocognitive functioning, affect work functioning. Cancer survivors used several strategies (e.g., applying practical adjustments, re-organization of work, and accepting limitations) to cope with cancer-related cognitive problems at work, as did professionals in their attempt at supporting cancer survivors facing these problems. Various needs of cancer survivors (e.g., supportive care options, acknowledgment by others) and professionals (e.g., improvement of expertise, clarity about referral pathways) regarding cancer-related cognitive problems at work were mentioned. CONCLUSIONS: Due to the growing number of working cancer survivors dealing with cancer-related cognitive problems, it is essential to sustain their employability. Therefore, cognitive rehabilitation interventions should be developed, taking functioning at work into account. Knowledge amongst professionals regarding cancer-related cognitive problems, as well as coordination of care for cancer-related cognitive problems, should be improved. Ensuring professional education regarding cancer-related cognitive problems, within both the healthcare and occupational setting, is of utmost importance. IMPLICATIONS FOR CANCER SURVIVORS: Support for working cancer survivors who experience cancer-related cognitive problems might increase their employability in the longer term.

OBJECTIVE: To investigate the effectiveness and feasibility of a Socratic feedback programme to improve awareness of deficits in patients with acquired brain injury (ABI). SETTING: Rehabilitation centre. PARTICIPANTS: Four patients with ABI with awareness problems. DESIGN: A series of single-case experimental design studies with random intervention starting points (A-B + maintenance design). MAIN MEASURES: Rate of trainer-feedback and self-control behaviour on everyday tasks, patient competency rating scale (PCRS), self-regulating skills interview (SRSI), hospital anxiety and depression scale. RESULTS: All patients needed less trainer feedback, the change was significant in 3 out of 4. One patient increased in overt self-corrective behaviour. SRSI performance increased in all patients (medium to strong effect size), and PCRS performance increased in two patients (medium and strong effect size). Mood and anxiety levels were elevated in one patient at the beginning of the training and decreased to normal levels at the end of the training. The feasibility of the programme was scored 9 out of 10. CONCLUSIONS: The Socratic feedback method is a promising intervention for improving awareness of deficits in patients with ABI. Controlled studies with larger populations are needed to draw more solid conclusions about the effect of this method.

Performance Validity Tests (PVTs) are used to measure the credibility of neuropsychological test results. Until now, however, a minimal amount is known about the effects of feedback upon noncredible results (i.e., underperformance) on subsequent neuropsychological test performance. The purpose of this study was to investigate the effects of feedback on underperformance in Chronic Fatigue Syndrome (CFS) patients. A subset of these patients received feedback on Amsterdam Short-Term Memory (ASTM) failure (i.e., feedback [FB] group). After matching, the final sample consisted of two comparable groups (i.e., FB and No FB; both n = 33). At baseline and follow-up assessment, the patients completed the ASTM and two measurements of information processing speed (Complex Reaction Time [CRT] and Symbol Digit Test [SDT]). Results indicated that the patients in the FB group improved significantly on the CRT, compared to the No FB group. Although not significant, a comparable trend-like effect was observed for the SDT. Independent of the feedback intervention there was a substantial improvement on ASTM performance at re-administration. A limited feedback intervention upon underperformance in CFS patients may result in improvement on information processing speed performance. This implies that such an intervention might be clinically relevant, since it maximizes the potential of examining the patients' actual level of cognitive abilities.

OBJECTIVE: Performance and symptom validity tests (PVTs and SVTs) measure the credibility of the assessment results. Cognitive impairment and apathy potentially interfere with validity test performance and may thus lead to an incorrect (i.e., false-positive) classification of the patient's scores as non-credible. The study aimed at examining the false-positive rate of three validity tests in patients with cognitive impairment and apathy. METHODS: A cross-sectional, comparative study was performed in 56 patients with dementia, 41 patients with mild cognitive impairment, and 41 patients with Parkinson's disease. Two PVTs - the Test of Memory Malingering (TOMM) and the Dot Counting Test (DCT) - and one SVT - the Structured Inventory of Malingered Symptomatology (SIMS) - were administered. Apathy was measured with the Apathy Evaluation Scale, and severity of cognitive impairment with the Mini Mental State Examination. RESULTS: The failure rate was 13.7% for the TOMM, 23.8% for the DCT, and 12.5% for the SIMS. Of the patients with data on all three tests (n = 105), 13.5% failed one test, 2.9% failed two tests, and none failed all three. Failing the PVTs was associated with cognitive impairment, but not with apathy. Failing the SVT was related to apathy, but not to cognitive impairment. CONCLUSIONS: In patients with cognitive impairment or apathy, failing one validity test is not uncommon. Validity tests are differentially sensitive to cognitive impairment and apathy. However, the rule that at least two validity tests should be failed to identify non-credibility seemed to ensure a high percentage of correct classification of credibility.
