Reliable Digit Span (RDS) is a heavily researched symptom validity test with a recent literature review yielding more than 20 studies ranging in dates from 1994 to 2011. Unfortunately, limitations within some of the research minimize clinical generalizability.

1 Ιουν 2020 · Results. Compared to peers with typical development, delayed discounting was significantly stronger in children with ADHD and discounting rates increased in both groups for heavier memory loads. Furthermore, the memory load impact on frequency of immediate rewards was stronger in children with ADHD compared to typically developing children.
19 Μαΐ 2011 · For Reliable Digit Span, the optimal cut-score was ≤6, with sensitivity of 51% and specificity of 92%. 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.
1 Ιαν 2018 · The current findings are also consistent with recent evidence that WISC-IV digit span classifies ADHD and Non-ADHD children at chance levels (Colbert and Bo, 2017, Tarle et al., 2017), whereas criterion working memory tasks that include increased central executive demands, a greater number of trials, and partial-credit scoring methods ...
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). Outcomes and results: Traditional digit span backward scores failed to predict working memory or KTEA-2 achievement (allns ...
14 Απρ 2022 · This study investigated the utility of four WAIS-IV Digit Span (DS) indices (traditional Reliable Digit Span [RDS], RDS-Working Memory [RDS-WM], RDS-Revised [RDS-R], and DS Age-Corrected Scaled Score [ACSS]) as embedded performance validity tests (PVTs) among a sample of 342 consecutive adults referred for neuropsychological evaluation of ADHD.
Outcomes and Results—Traditional digit span backward scores failed to predict working memory or KTEA-2 achievement (all ns). Alternate administration/scoring of digit span backward significantly improved its associations with working memory reordering (r=.58), working memory
