Ceiling effects occur in subtests (VPAII, VRI, and VRII) on which individuals score most of the total possible points at the first testing session; this makes interpretation of practice effects difficult. Practice effects in repeated neuropsychological assessments. Author information: (1)Department of Psychology, University at Albany, State University of New York, 12222, USA. 1992; 6:32–42. The implications of these longer lasting effects and practice effects on reliability were examined in the context of repeated administrations of the Wechsler Memory Scale‐III in 339 community‐dwelling women aged 40–79 years over 2 to 7 years. Objectives: Repeated neuropsychological assessments are often used to monitor change in cognitive functioning over time. McCaffrey RJ(1), Ortega A, Haase RF. Repeated measure ANOVAs were calculated on both standardized and raw scores with similar results. Practice effects are assumed to operate only between the first and second administration of a neuropsychological test battery, 25 but recent reports suggest that, at least for some tests, they may influence performance on up to four serial assessments. The correction … Considering that repeated evaluations are a common need in neuropsychological assessment routines, we explored test–retest reliabil- ity and practice effects of two alternate SDMT forms with a short inter-assessment interval. Arch Clin Neuropsychol (1992). OpenUrl CrossRef ↵ McCaffrey RJ, Duff K, Westervelt HJ. A total of 123 university students completed the written SDMT version in two different time points separated by a 150-min interval. Methods for test equating are particularly important for neuropsychological assessments in population-based research and clinical practice. However, when repeated testing occurs over a period of years, there will be some longer lasting effects. Considering that repeated evaluations are a common need in neuropsychological assessment routines, we explored test–retest reliability and practice effects of two alternate SDMT forms with a short inter-assessment interval. While assessments are typically separated by months or years, rapid interval testing is occasionally used in cases of acute injury and recovery. Repeated neuropsychological testing gives rise to practice effects in that patients become familiar with test material as well as test-taking procedures. Hughes EA: Nine Parallel Versions of Four Memory Tests: An Assessment of Form Equivalence and … Clin Neuropsychol 1992 ; 6 : 32 – 42 . Thus, the RBANS appears to offer both the sensitivity and reliability necessary for repeated assessments. These beneficial practice effects can have a significant impact on test performance when conventional neuropsychological tests are administered at test-retest intervals of weeks, months or years. N2 - Introduction: Practice effects are characteristic of nearly all standard cognitive tasks when repeated during serial assessments and are frequently important confounders in clinical trials. Of the range of potential uses of serial cognitive assessment—including clinical practice and observational and natural history studies—one might assume that randomized controlled trials may be a context in which practice and retest effects are of the least concern. 6, 21 – 26 The neuropsychological tests are not the only assessments potentially confounded by practice effects; practice effects have also been found in other assessments of postural stability. However, changing forms could diminish test-retest reliability coefficients. Potential methodological procedures for reducing the impact of practice effects in research settings are outlined. Sweet, Deborah K. Attix, Kevin R. Krull, George K. Henry, and Robert P. Hart American Academy of Clinical Neuropsychology Serial assessments are now common in neuropsychological practice, and have a … Thus, knowledge about the reliability and stability of neuropsychological tests and the effects of age and IQ is of paramount importance. The results showed that Logical … Mitrushina M, Satz P. Effect of repeated administration of a neuropsychological battery in the elderly. They may help to track cognitive disorders over time, to stage disease 130 severity, and to measure the effect of pharmacological or rehabilitative treatment. Using alternate forms prevents the learning of specific test stimuli, potentially mitigating practice effects. In addition, the RBANS offers age-scaled norms and an alternate form to aid in circumventing age and practice effects. Test-retest reliability coefficients, mean change scores from Session 1 to Session 2, standard errors of prediction, and 95% confidence intervals are presented. 469 - 479. Practice effects in repeated neuropsychological assessments . Distinguishing practice effects from other factors in repeated neuropsychological assessments are discussed in the context of research studies and clinical/forensic assessments. Practice effects in repeated neuropsychological assessments. Haase RF: Effects of repeated neuropsychological assessments. Clin Neuropsychol 1992; 6: 32 –42. Repeated neuropsychological assessments play a central role in the monitoring of a variety of neurological conditions (e.g. A total of 123 university students completed the written SDMT version in two different time points separated by a 150-min interval. J Clin Exp Neuropsychol 1998; 20: 339 –52. Administration of test versions would be counterbalanced. Additionally, serial cognitive assessments are … Previous investigations with neuropsychological test batteries have revealed practice effects or improvement in performance as a function of having previously taken the test or performed the task. Alternate versions of a test are considered equivalent if they produce the same mean and variance in a sample (Borsboom, 2005). Many recent investigations have sought to determine changes in cognitive function over periods of minutes or hours (e.g., before and after anesthesia) using computerized tests. Cipolotti & Warrington, 1995). Practice effects. Wilson, BA, Watson, PC, Baddeley, AD, Emslie, H & Evans, JJ 2000, ' Improvement or simply practice? Haase RF: Practice effects in repeated neuropsychological assessments. A clinical trial using tests that are designed to avoid the impact of practice‐related effects would look very much like current trials in which baseline assessment at T0 by version A of the test was followed by three more assessments (T1‐version B, T2‐version C, and T3‐version D) over an 18‐month period. DISCUSSION Reflecting the heterogeneity of MCI, practice effects on repeated tests may be variable. 6, pp. This review presents meta-analyses of nearly 1600 individual effect sizes representing changes in mean-level performance on tests commonly used to assess core domains of neuropsychological function, with the goal of quantitatively summarizing the magnitude of practice effects on such tests. Neuropsychological tests and test–retest interval may affect the practice effect. Considering that repeated evaluations are a common need in neuropsychological assessment routines, we explored test-retest reliability and practice effects of two alternate SDMT forms with a short inter-assessment interval. The Bonferroni correction is an adjustment made to reduce type 1 errors when multiple pairwise comparisons are performed. McCaffrey RJ, Ortega A, Orsillo SM, Nelles WB. Indeed, this use of the cognitive baselines has increased in importance. The current paper will review some of the relevant concepts (e.g., reliability, practice effects, alternate forms) and methods (e.g., reliable change index, standardized based regression) that are used in repeated neuropsychological evaluations. Based on consultation with research medical librarians (DKNL and JR), our search strategy used the following key search terms: practice effects, learning effects, retest effects, repeat testing, serial testing, serial assessment, longitudinal testing, neuropsychological testing, cognitive change, reliability, and early detection. Repeated neuropsychological (NP) assessments are common in clinical practice, as neuropsychologists frequently must make determinations about disease and injury progression or recovery. 85 Neuropsychological tests are typically presented as ‘pencil and paper’ tasks; ... 128 Parallel forms (alternative versions using similar material) may reduce the effect of learning effect 129 from repeated evaluations. Practice Effects Associated with the Repeated Assessment of Cognitive Function Using the CogState Battery at 10-minute, One Week and One Month Test-retest Intervals . NEUROPSYCHOLOGICAL ASSESSMENTS: THE UTILITY AND CHALLENGES OF REPEAT TEST ADMINISTRATIONS IN CLINICAL AND FORENSIC CONTEXTS Robert L. Heilbronner, Jerry J. To determine if any practice effects were associated with serial administration of the reaction time, we performed a repeated-measures analysis of variance. To adjust the practice effect from repeated neuropsychological tests used in this study, we enrolled 184 control subjects who were not exposed to surgery. Repeated assessments are a relatively common occurrence in clinical neuropsychology. In this study we document, for six cognitive tests: test‐retest reliabilities, practice effects, reliable change (RC) indices … Practice effects during repeated administrations of memory test with and without alternate forms. The effects of twenty repeated assessments on people with and without brain injury ', Journal of the International Neuropsychological Society, vol. HJ: Practitioner’s guide to evaluating change with neuropsychological assessment instruments (1994). Clin Neuropsychol. 22. A total of 123 university students completed the written SDMT version in two different time points separated by a 150-min interval. Reliable assessment of change from previous cognitive functioning is a prerequisite for determining the possible presence of neurodegenerative diseases such as Alzheimer's disease (AD). Effects of repeated neuropsychological assessments. The aim of the current study was to test the accuracy of practice effects, that is, improvement in test performance due to repeated neuropsychological evaluations, in identifying patients with amnestic mild cognitive impairment (a-MCI) at greater risk of conversion to Alzheimer disease (AD). doi: 10.1080/13854049208404115. Clin Neuropsychol (2000). repeated evaluations are a common need in neuropsychological assessment routines, the present work is aimed to explore the test-retest reliability and practice effects associated with two alternate SDMT forms in the context of a short inter-assessment interval. Post hoc pairwise comparisons with Bonferroni adjustments were conducted if necessary. OpenUrl PubMed Web of Science ↵ McCaffrey RJ, Ortega A, Orsillo SM, et al.
