Digit span wais iv12/29/2023 Several recent clinical case series have also consistently found that a small percentage of general pediatric patients perform suboptimally because of effort-related problems ( Carone, 2008 Donders, 2005 Kirk et al., 2011 MacAllister, Nakhutina, Bender, Karantzoulis, & Carlson, 2009). However, a number of single-case reports have clearly documented that children can feign cognitive impairment during neuropsychological examination ( Flaro & Boone, 2009 Henry, 2005 Kirkwood, Kirk, Blaha, & Wilson, 2010 Lu & Boone, 2002 McCaffrey & Lynch, 2009). In comparison to the vast literature focused on noncredible neuropsychological performance in adults, the pediatric literature is relatively sparse. Indeed, classification statistics produced in this pediatric sample compare favorably with those produced in many real-world adult patients.ĭigit span, Reliable digit span, Wechsler intelligence scale for children, Symptom validity testing, Response bias, Postconcussion, Mild traumatic brain injury Introduction Although only moderately sensitive, Digit Span scores are likely to have good utility in identifying noncredible performance in relatively high-functioning older children and adolescents. For Reliable Digit Span, the optimal cut-score was ≤6, with sensitivity of 51% and specificity of 92%. For age-corrected scaled scores, a score of ≤5 resulted in the optimal cut-score, yielding sensitivity of 51% and specificity of 96%. Fourteen percent of the participants failed both the Medical Symptom Validity Test and Test of Memory Malingering, which was used as the criterion for noncredible effort. The sample consisted of 274 clinically referred mild traumatic brain injury patients aged 8 through 16 years. The present study examined the classification value of several scores derived from the WISC-IV Digit Span subtest. Although several recent studies have demonstrated the appropriateness of using stand-alone symptom validity tests with younger populations, a near absence of pediatric work has investigated embedded validity indicators. Far less work has focused on methods appropriate for children. Both poorer DSS performance and the presence of perseveration can offer useful clinical information on the context of a thorough evaluation of the aMCI/DAT spectrum.Īlzheimer disease WAIS-IV digit span sequencing working memory.In adult populations, research on methodologies to identify negative response bias has grown exponentially in the last two decades. Discontinuation of DSS due to cross-task perseveration was frequently seen in, although not unique to, the DAT group. Conclusions: The DS sequencing results differed between the three clinical groups, which is consistent with the hypothesis that working memory declines would be evident on this measure. Digit Span Sequencing was significantly different in each group (DAT < aMCI < SCC), with a high rate of the DAT group showing cross-task perseveration. Results: Those with DAT performed significantly worse for DS Forward, Backward, and Total Score versus those with aMCI and SCC, whose performances were similar. This resulted in a sample of 290 individuals with DAT, 255 with aMCI, and 161 with SCC. Method: Seven hundred and six individuals were drawn from 1256 consecutive referrals who underwent a standard neuropsychological evaluation and obtained a consensus diagnosis from a neuropsychologist and a neurologist of DAT, aMCI, or having SCC. ![]() This study examines performance on DS for individuals from a memory disorder clinic diagnosed with amnestic mild cognitive impairment (aMCI), probable dementia of the Alzheimer type (DAT), or those with subjective cognitive complaints (SCC). Objective: The Digit Span (DS) subtest from the Wechsler Adult Intelligence Scale-4 th Edition (WAIS-IV) was updated to better measure working memory which is potentially clinically relevant as prior unreplicated studies showed that sequencing tasks differentiated normal from neurologic groups.
