![]() ![]() ![]() Once a subscription is activated, it cannot be paused or suspended for any reason and will run continuously for the duration of the course material. We recommend that all subscriptions be activated within 180 days of setup/purchase. This process of activating a subscription after purchase allows you the flexibility to start a subscription when you are truly ready to use it. If your initial purchase consists of multiple courses (Qbank, Self-Assessment exam, CCS, etc.), each can be activated individually and independently via your account on our website. A subscription can be activated immediately or any time thereafter. The RCI for the tasks can be used to track significant changes in longitudinal assessment, although the high variability and moderate reliability of the tasks are likely to hinder assessment of mild or slight changes.New Purchase: All new subscriptions go into effect from the time they are activated and not at the time of setup/purchase. Reliability was high for Digit Span forward, low for Digit Span backward, and moderate for the Corsi Block-Tapping task. Table 1 shows descriptive data, internal consistency, and reliable change coefficients for each task. ![]() Reliable change indexes (RCIs) were calculated for all test measures. Reliability was estimated by the split-half method, using the first trials from each span to compose the first half and the second trials to compose the second half. Two errors in the same span prompted interruption of the task. Two trials were administered for each span (sequence length ranging from 2 to 8), in forward and reverse order, in both tasks. The same examiner administered and scored both tasks in all participants. The study was approved by the Universidade Federal de Minas Gerais Ethics Committee and conducted in accordance with the Declaration of Helsinki. Psychometric properties of the Brazilian version of Pfeffer's Functional Activities Questionnaire. Assis Lde O, de Paula JJ, Assis MG, de Moraes EN, Malloy-Diniz LF. Mattis dementia rating scale (DRS) normative data for the Brazilian middle-age and elderly populations. Foss MP, Carvalho VA, Machado TH, Reis GC, Tumas V, Caramelli P, et al. Diagnosis involved cognitive and functional assessment, performed with the Brazilian versions of the Mattis Dementia Rating Scale 4 4. To analyze the reliability of the Digit Span and Corsi Block-Tapping tasks, we assessed 25 older adults with low formal education referred for neuropsychological assessment due to cognitive-functional complaints (13 patients with mild and 12 with major neurocognitive disorder, irrespective of etiological diagnosis). Clinical significance: a statistical approach to defining meaningful change in psychotherapy research. follow-up) are likely due to measurement error (imprecision of test measures) or are associated with an external factor (the intervention, a placebo, or other non-documented causes). These are simple statistical procedures used to examine whether changes in test scores over time (e.g., pre-intervention vs. Test reliability is an important measure used to estimate test precision and to create reliable change coefficients. However, we are unaware of studies investigating the reliability of these tasks for WM assessment in older adults diagnosed with neurocognitive disorders. Both tests are commonly used in neuropsychological assessment of older adults with a diagnostic hypothesis of pathological aging (e.g., minor and major neurocognitive disorders). The Corsi Block-Tapping task uses nine cubes placed on a wooden board to assess visuospatial WM. The Digit Span uses escalating series of numbers from 1 to 9, presented in a randomized fashion, to assess verbal WM. In both tests, the subject must repeat a series of stimuli in the presented order (forward) or in the inverse order (backward). The backward span of the Corsi Block-Tapping Task and its association with the WAIS-III Digit Span. Kessels RP, van den Berg E, Ruis C, Brands AM. The Digit Span and Corsi Block-Tapping tasks are frequently used in WM assessment. Furthermore, as a cognitive process, WM is key to understanding functional capacity in clinical samples. Despite the lack of a consensus definition and theoretical model to explain this function, its assessment is a key aspect in clinical practice, both for diagnostic and intervention purposes. Working memory: theories, models, and controversies. Working memory (WM) is a core aspect of executive function, related to temporary storage of information to be manipulated and used by other cognitive processes. ![]()
