Multiple sclerosis (MS) is frequently accompanied by changes in verbal memory. We hypothesized that administering an abbreviated California Verbal Learning Test-II (CVLT-II) would detect verbal memory problems in MS accurately, thus serving as a potential screening tool. We performed receiver-operating-characteristic (ROC) analyses of three trials (trial 1, trial 2, and trial 1+2 combined) for raw data against standardized total scores. The results showed that at 1.5 standard deviations (SD) from the mean, the first two trials were 96.3% accurate, while at 2 SD from the mean, the first two trials combined were 97.5% accurate. We conclude that this study demonstrates than an abbreviated CVLT-II is a valid screening tool for verbal memory impairments.

We used the California Verbal Learning Test, Second Edition (CVLT-II), one component of the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS), to determine feasibility of a remote assessment protocol. We compared telephone-administered CVLT-II data from MS patients to data acquired in person from an independent sample of patients and healthy controls. Mixed factor analyses of variance (ANOVAs) showed no significant differences between patient groups, but between-group effects comparing patients and healthy controls were significant. In this study, CVLT-II assessment by conventional in-person and remote telephone assessment yielded indistinguishable results. The findings indicate that telephone-administered CVLT-II is feasible. Further validation studies are underway.

Abstract Objective As new measures of memory become available, clinicians may be cautious to adopt them without evidence supporting their validity. The present study assesses the convergent and divergent validity of the Child and Adolescent Memory Profile (ChAMP), with the California Verbal Learning Test Children’s (CVLT-C) and the Rey Complex Figure Test (RCFT) in children with epilepsy. Method Twenty four clinically referred children (16 female, 8 male, - age = 12.37 years, SD = 2.68) completed the ChAMP, CVLT-C, and RCFT. Pearson correlations assessed the ChAMP’s convergent and divergent validity with the CVLT-C and the RCFT. Base rate of impairment was calculated for scores ≤2nd percentile. Results The ChAMP verbal tasks demonstrated strong relations with CVLT-C (lists; r = 0.678 p = < .001, instructions; r = 0.724 p = < .001 with CVLT-C learning trials and ChAMP lists free recall with CVLT-C long delay r = 0.580 p = .003). The ChAMP visual tasks correlated strongly with the RCFT delay (objects; r = 0.570 p = .004, places; r = 0.619 p = .001, Visual Memory Index; r = 0.657 p = < .001). However, divergent validity was limited as ChAMP Verbal Memory Index correlated with RCFT delay (r = 0.550 p = .005) and ChAMP Visual Memory Index with CVLT-C delay (r = 0.606 p = .002). Eight percent were deemed impaired on ChAMP lists delay similar to the CVLT-C delay (13%), however, ChAMP places delay identified 21% impaired, compared to the RCFT delay (42%). Conclusions ChAMP scores are strongly correlated with older established measures, but identify fewer cases as clinically impaired. This may reflect the more contemporary normative data or the fact that ChAMP tasks are less multifactorial in nature than are the CVLT-C and RCFT.

AbstractCompared to other cognitive functions in schizophrenia, evidence suggests that verbal memory is particularly impaired. This study used the California Verbal Learning Test (CVLT) to examine proactive inhibition (PI) and semantic processing in verbal memory in 29 patients with schizophrenia and 29 healthy controls. Patients showed significantly less PI, but also did not organize (cluster) their recall according to semantic category. Controls and patients demonstrated small retroactive inhibition (RI) effects regardless of semantic content. Although both groups made similar types and numbers of free recall intrusion errors, patients committed more phonemic and nonshared recognition errors. Results suggest that reduced semantic processing prevented build of PI, and contributes to defective memory in schizophrenia. The anatomic-physiologic abnormalities that underlie these findings may be particularly pronounced in prefrontal and temporal-parietal cortical areas. (JINS, 1996, 2, 486–493.)

Abstract Objective This study was conducted to investigate how items contained within the California Verbal Learning Test – Second Edition (CVLT-II; Delis, D. C., Kramer, J. H., Kaplan, E., & Ober, B. A. (2000). California Verbal Learning Test (2nd ed.). San Antonio, TX: Psychological Corporation) learning trials function and to evaluate whether weighted scoring approaches might improve quantification of verbal memory. Method Archival data from 577 individuals (338 healthy young adults, 239 medical or psychiatric patients referred to a neuropsychology clinic) were obtained and evaluated using item response theory. Results The serial position effect was evident across trials, but was most evident in Trials 1, 2, and 3. CVLT-II Trial 5 was the most effective among the five learning trials in quantifying verbal memory, although it was most effective when measuring lower memory ability levels. In contrast, CVLT-II Trial 1 items had, on average, the highest difficulty levels. Various weighted scoring approaches did not appear incrementally helpful in improving prediction of memory performance. Conclusion Specific items and trials differentially discriminate between examinees with low levels of memory ability; it is important to thoroughly evaluate item properties of tests used in clinical decision-making.

Aims:Verbal memory and processing speed are two of the proposed neurocognitive predictors in schizophrenia. the objective is to determinate neurocognitive predictors of functioning in one five years follow-up period on ambulatory schizophrenia patients.Method:We conduct one cohort study on 30 schizophrenia out-patients (19 male; age mean: 32.8 years; SD:7.2). at the moment of inclusion it was applied one neuropsychological battery sensitive to neuropsychological deficit in schizophrenia: WAIS-III, BADS, WCST, Colour Trails, Trail Making A and B, BVRT, California Verbal Learning Test (Spanish version: TAVEC). Variables was summarized determining Z values and principal components. the cohort was prospectively studied for up to five years. as result variables it were considered: time to the first antipsychotic-drug change, time to the first psychiatric admission, and average five-years annual score in the Strauss-Carpenter Outcome Scale. It was constructed Cox and Linear Regression Models to determinate the better predicting neurocognitive components.Results:The better global outcome was directly related with WAIS-III processing speed index (corrected R square: 0.19; p = 0.02; beta constant= 0.469; beta WAIS-III processing speed= 0.125). None predictor was selected for the outcome variable change of antipsychotic. Psychiatric admission was predicted (p=0.006) by implicit learning (beta= -2.19), executive functioning (beta= 1.02), WAIS-III Total IQ (beta= 0.45) and WAIS-III Perceptual Organization Index (beta= -0.20).Conclusion:Higher processing speed index predicts one better functioning outcome during five-years follow-up. the risk for psychiatric admission was heterogeneously related with neurocognitive predictors. Verbal memory did not predict functional outcome.

There is evidence in the literature that cognitive functions in schizophrenia (SC) may be improved by atypical neuroleptics (NLPs) in contrast to typical medication, but there is still controversy regarding this apparent superiority of atypical drugs. In this study, we assessed the differential effects of risperidone and haloperidol on verbal memory, attention, and psychiatric symptoms in SC. The performance of 28 SC participants, randomly assigned to risperidone (2–6 mg/day) or haloperidol (2–40 mg/day), was compared with that of healthy controls. The California Verbal Learning Test (CVLT), the d2 Cancellation Test, and the Positive and Negative Symptoms Scale were administered at baseline and 3, 6, and 12 months. Relative to controls, all SC participants showed markedly impaired verbal memory and processing speed at each assessment period. There was no differential effect between the two NLPs on CVLT and d2 performance. However, risperidone was more effective than haloperidol in reducing psychiatric symptoms. Improvement in symptom severity was not associated with improvement in neurocognitive performance on these specific tests. Neither conventional nor atypical neuroleptic medications improved neurocognitive functioning over a 12-month follow-up, suggesting that psychopathological improvement under risperidone is independent of cognitive function.

Little is known about possible differences in the memory deficits that occur in Dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). We compared 24 autopsy-confirmed DLB and 24 age-, education-, and MMSE-matched autopsy-confirmed AD patients on the California Verbal Learning Test (CVLT) and the Wechsler Memory Scale-Revised Logical Memory subtest. The DLB and AD groups were similarly impaired on CVLT Total Learning (Trials 1–5) and Long Delayed Free Recall, but the DLB group demonstrated relative improvement in Savings scores and on recognition testing compared to the AD group. Likewise, the patient groups were equally impaired on Logical Memory immediate and delayed recall, but the DLB group's Saving scores were significantly better than those of the AD patients. These results indicate that while both DLB and AD patients exhibit significant memory impairment, the ability to consolidate information may be less severely impaired in DLB patients than in AD patients.
