However, Digit Span scaled score accounted for a modest amount of variation and it is not recommended as a stand-alone validity measure. Application of this cutoff score to a non-litigating mild brain injury group yielded a 77% correct classification rate. A cutoff score of less than or equal to 7 accurately classified 75% of persons in the incomplete effort group and 69% of persons in the TBI group. They were first given the Backward Digit Span and WAIS Arithmetic test. The Digit Span scaled score was found to be the best discriminating index. This was taken from the Wechsler Adult Intelligence Scale-IV (Wechsler, 2008). Various indices from the Digit Span subtest were evaluated to determine the best discriminator of brain injury from poor motivation patient groups: Digit Span Forward, Digit Span Backwards, Reliable Digit Span, Digit Span Age-Corrected Scaled Score, and the difference score between the Vocabulary and Digit Span scaled scores. Hoboken, NJ: John Wiley.The current study evaluated the utility of the Digit Span subtest in discriminating patients with mild head trauma from individuals referred for independent neuropsychological evaluation with objective evidence of poor effort.

Base Rate for Intersubtest Scatter is reported for 10 Full Scale Subtests. Verbal learning and memory were assessed using the California Verbal Learning Test (CVLT), with derived scores including short and long free recall and the learning slope. Next, items based on the Digit Span Backward and Forward (span 3-4-5) were used to measure attention span and working memory.
