The SAGES telephone neuropsychological battery: correlation with in-person measures.

ABSTRACT: OBJECTIVE:Neuropsychological test batteries are administered in person to assess cognitive function in both clinical and research settings. However, in-person administration holds a number of logistical challenges that makes it difficult to use in large or remote populations or for multiple serial assessments over time. The purpose of this descriptive study was to determine whether a telephone-administered neuropsychological test battery correlated well with in-person testing. METHODS:Fifty English-speaking patients without dementia, over 70?years old, and part of a cohort of patients in a prospective cohort study examining cognitive outcomes following elective surgery were enrolled in this study. Five well-validated neuropsychological tests were administered by telephone to each participant by a trained interviewer within 2-4 weeks of the most recent in-person interview. Tests included the Hopkins Verbal Learning Test-Revised, Digit Span, Category Fluency, Phonemic Fluency, and Boston Naming Test. A General Cognitive Performance composite score was calculated from individual subtest scores as a Z-score. RESULTS:Mean age was 74.9?years (SD?=?4.1), 66% female, and 4% non-White. Mean and interquartile distributions of telephone scores were similar to in-person scores. Correlation analysis of test scores revealed significant correlations between telephone and in-person results for each individual subtest, as well as for the overall composite score. A Bland-Altman plot revealed no bias or trends in scoring for either test administration type. CONCLUSIONS:In this descriptive study, the telephone version of a neuropsychological test battery correlated well with the in-person version and may provide a feasible supplement in clinical and research applications.

Project description:IntroductionAssessment of preclinical Alzheimer's disease (AD) requires reliable and validated methods to detect subtle cognitive changes. The battery of standardized cognitive assessments that is used for diagnostic criteria for mild cognitive impairment due to AD in the TOMMORROW study have only been fully validated in English-speaking countries. We conducted a validation and normative study of the German language version of the TOMMORROW neuropsychological test battery, which tests episodic memory, language, visuospatial ability, executive function, and attention.MethodsGerman-speaking cognitively healthy controls (NCs) and subjects with AD were recruited from a memory clinic at a Swiss medical center. Construct validity, test-retest, and alternate form reliability were assessed in NCs. Criterion and discriminant validities of the cognitive measures were tested using logistic regression and discriminant analysis. Cross-cultural equivalency of performance of the German language tests was compared with English language tests.ResultsA total of 198 NCs and 25 subjects with AD (aged 65-88 years) were analyzed. All German language tests discriminated NCs from persons with AD. Episodic memory tests had the highest potential to discriminate with almost twice the predictive power of any other domain. Test-retest reliability of the test battery was adequate, and alternate form reliability for episodic memory tests was supported. For most tests, age was a significant predictor of group effect sizes; therefore, normative data were stratified by age. Validity and reliability results were similar to those in the published US cognitive testing literature.DiscussionThis study establishes the reliability and validity of the German language TOMMORROW test battery, which performed similarly to the English language tests. Some variations in test performance underscore the importance of regional normative values. The German language battery and normative data will improve the precision of measuring cognition and diagnosing incident mild cognitive impairment due to AD in clinical settings in German-speaking countries.

Project description:BACKGROUND:The Cambridge Neuropsychological Test Automated Battery (CANTAB) is a computerized tool used to measure cognitive function in diverse populations and is sensitive for assessing developmental changes in children. Although CANTAB has been used in several countries, its applicability in a Mexican child population is unknown. This study examined developmental trends on CANTAB in a large sample of urban Mexico City youth and tested the hypothesis that their performance would be similar to a large US normative sample. METHOD:As part of a birth cohort, Early Life Exposures in Mexico to Environmental Toxicants, 826 children, ages 5-15 years, completed CANTAB. Subtests measured planning (Stockings of Cambridge; SOC), short-term memory (Delayed Matching to Sample; DMS), sustained attention (Rapid Visual Information Processing; RVP), ability to match visual stimuli (Match to Sample Visual Search; MTS), flexibility (Intra-extra Dimensional Set Shift; IED), and response inhibition (Stop Signal Task; SST). Determinants of performance on the CANTAB, including age, maternal/child IQ, and sex, were analyzed using Spearman correlation and Welch t tests. Equivalence testing compared performance with existing norms. RESULTS:Performance improved with age on all measures. Child IQ was mildly associated with measures of memory and attention but not executive functioning, consistent with US norms. Maternal IQ was not associated with any outcomes, and males performed better on IED. Mexican norms were comparable to US norms on almost all outcomes, with the exception of a short-term visual recognition memory task (DMS). CONCLUSIONS:This study provides the largest normative data for CANTAB performance in a community sample of Mexican youth. Findings demonstrate the expected maturational effects of executive function, specifically in cognitive shifting and inhibition. Levels of executive function performance demonstrated by a Mexican sample were consistent with normative values reported in US youth. These findings, as well as expected associations with child IQ, indicate high applicability of CANTAB for Mexican youth in neurobehavioral studies.
