Digit span backward becomes a valid measure of working memory at exactly the point that testing is traditionally discontinued.Ĭopyright © 2017 Elsevier Ltd. Minor test modifications may address test validity concerns, and should be considered in future test revisions. Alternate administration/scoring of digit span backward significantly improved its associations with working memory reordering (r=.58), working memory dual-processing (r=.53), working memory updating (r=.28), and KTEA-2 achievement (r=.49).Ĭonsistent with prior work, these findings urge caution when interpreting digit span performance. Traditional digit span backward scores failed to predict working memory or KTEA-2 achievement (allns). Here, Digit Sp Name earned a score at the end of the. Notably, cognitive flexibility, and mental alertness are required when shifting from one an task to another. ![]() Backward, Name is read a sequence of numbers and recalls the numbers in reverse order. Traditional and modified scores were compared to a battery of criterion working memory (construct validity) and academic achievement tests (predictive validity) for 34 children with ADHD ages 8-13 (M=10.41 11 girls). Forward a score in the range for a person his age. ![]() WISC-IV digit span was modified to administer all trials (i.e., ignore discontinue rule) and count digits rather than trials correct. The current study pilot-tested minor administration/scoring modifications to improve digit span backward's construct and predictive validities in a well-characterized sample of children with ADHD. Pediatric ADHD is associated with impairments in working memory, but these deficits often go undetected when using clinic-based tests such as digit span backward.
