![]() Indeed, classification statistics produced in this pediatric sample compare favorably with those produced in many real-world adult patients. Note that in the WICS-IV, Digit Span is included in the Full-Scale IQ in the Working Memory Scale with a new subtest called Letter-Number Sequencing. 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. High Digit Span scores suggest a superior ability to concentrate and memorize orally presented information. For any given span size (n) the participant will be shown n digits that are randomly selected between 10 and 99. For Reliable Digit Span, the optimal cut-score was ≤6, with sensitivity of 51% and specificity of 92%. The digit span task is a simple short-term memory measure that involves the storage and recall of digits in correct serial position. For age-corrected scaled scores, a score of ≤5 resulted in the optimal cut-score, yielding sensitivity of 51% and specificity of 96%. The FSIQ is considered the most representative indicator of general intellectual functioning. 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 Full Scale IQ (FSIQ) composite score summarizes ability across a diverse set of cognitive functions. ![]() The sample consisted of 274 clinically referred mild traumatic brain injury patients aged 8 through 16 years. The study sought to use Jensens two-level theory of mental abilities to predict some hitherto unknown or unnoticed phenomena-facts about which the theory should yield clear-cut predictions and which are not as clearly predictable from other theories, though they may receive ad hoc explanations after the fact. The present study examined the classification value of several scores derived from the WISC-IV Digit Span subtest. Although the original version of this task was verbally administered, recent versions are generally administered via computer. Wechslers Digit Span subtest comprises of two parts digits forward, where the examinee is asked to repeat increasing spans of digits in the order they were. 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. The Digit Span Task is a simple behavioral measure of working memory capacity, the cognitive ability to store and manage information on a transient basis. Far less work has focused on methods appropriate for children. Nonword repetition scores provided excellent sensitivity. In adult populations, research on methodologies to identify negative response bias has grown exponentially in the last two decades. Results were compared with performance on a digit span task and norm-referenced test scores.
