![]() The DSB is an effective tool in identifying patients with major cognitive impairment. A significant association between scores on the DST and the Cantonese version of the Mini-Mental State Examination (CMMSE) was found in this study (p < 0.05 for DSF, p = 0.00 for DSB).ĭementia and delirium were prevalent, yet under-recognized, in acute medical geriatric inpatients. Regarding the detection of major cognitive impairment, the ROC curve of DSB showed a sensitivity of 0.77 and specificity of 0.78 at the optimal cutoff of <3. The prior case-note documentation rate was 13.2% for dementia and 2.8% for delirium. The prevalence rates of dementia alone, delirium alone and delirium superimposed on dementia were 21.5%, 9% and 9% respectively. Receiver Operating Characteristics curve (ROC) was used in conjunction with sensitivity and specificity measures to assess the performance of DST. The DST scores were compared with the psychiatrists' DSM-IV-based diagnoses. The objectives of this study were to (1) validate the Digit Span Test (DST) in the identification and differentiation of dementia and delirium and (2) determine the prevalence of major cognitive impairment in elderly people in an acute medical unit.ĭuring the study period from January to February 2010, 144 patients aged 75 years or more who had had unplanned medical admissions were assessed by nurses, using the Digit Span Forwards (DSF) and the Digit Span Backwards (DSB) tests. If your child has areas of weakness you'd like to help them improve, or areas of strength where they would like access to enrichment material, the links below will help you find appropriate material.There is no valid instrument currently in use at acute-care hospitals in Hong Kong to aid the detection of cognitive impairment. Browsing the resources below should reassure you that your child has been exposed to the skills tested for on the WISC even if you weren't doing it consciously. Finding out that their children will be taking a test like the WISC is often the first time they start to worry that they've missed something. Many parents have more difficulty knowing how to teach their children how to think. Only discontinue test when participant has failed both trials of the same span length (e.g. For example, if I say 7-1-9, what would you say 'Scoring: Each span is scored '1' (Pass) or '0' (Fail). Listen carefully, and when I am through say them right after me. Most parents have no difficulty knowing how to teach their children the alphabet or how to count. DIGIT SPAN TEST - FORWARD Examiner: 'I am going to say some numbers. If your child is tested they will be given clear instructions and the testing will not proceed unless the tester believes that they understand what they are required to do.Īny parent teaches their child and we look for quality resources to help us to do that. There is nothing on this page which is not publicly available information but we do not recommend that you attempt to familiarize your child with the content of the WISC using the information on this page or other sources. Part of the WISC test protocol is to see how children will do when presented with questions of a type they haven't seen before. Composite scores relating to specific cognitive areas may also be reported (index scores can be produced in the areas of Verbal Comprehension, Perceptual Reasoning, Working Memory and Processing Speed.) In addition to subtest scores a combined composite score is reported (the IQ). There are 15 subtests on the WISC-IV but they may not all be used. Get to the root cause of problems quickly, without losing context from switching between tools. You can read more about the WISC-IV here. Digit Span Tester Web Site Other Useful Business Software Collect, search, and correlate detailed logs from applications, infrastructure, and network devices for faster troubleshooting and investigation. Older children and adults are tested using the Wechsler Adult Intelligence Scale (WAIS). Younger children are tested using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI). The Wechsler Intelligence Scale for Children (WISC-IV) is an individually administered IQ test used with children aged from 6 to 16.
