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%. The median MS span was 6.45 with 92 of subjects producing MS scores between 5 and 7 digits. The lower tail of the TE-ML distribution was broad with 20.2 of subjects showing TE-MLs of 5 and 2.9 of subjects showing TE-MLs of 4. Diagnostic accuracy was calculated predicting group status across cutoff scores on two Digit Span variables, four Reliable Digit Span (RDS) variables, and two Vocabulary minus Digit Span. Of the total sample (N 275), 21.09 failed the MSVT and/or b Test. 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. TE-ML showed a median span of 6 with 80 of subjects showing spans between 5 and 7 digits. The Noncredible group included individuals who failed either the MSVT or the b Test. The sample consisted of 274 clinically referred mild traumatic brain injury patients aged 8 through 16 years. To make it more interesting, gradually increase the Span, which starts out at 8, and change to Fast test speed. Repeat the sequence of numbers shown during the test. The present study examined the classification value of several scores derived from the WISC-IV Digit Span subtest. A popular working memory test that is used in many cognitive and neuroscience research labs. 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. Magnetic resonance imaging (MRI) was done in a 1.5T clinical scanner (for. Far less work has focused on methods appropriate for children. A second possibility is that the olfactory memory span task is different in. In adult populations, research on methodologies to identify negative response bias has grown exponentially in the last two decades.
