Abstract

This study investigated the stability of Wechsler Intelligence Scale for Children–Fifth Edition (WISC-V) scores for 225 children and adolescents from an outpatient neuropsychological clinic across, on average, a 2.6 year test-retest interval. WISC-V mean scores were relatively constant but subtest stability score coefficients were all below 0.80 (M = 0.66) and only the Verbal Comprehension Index (VCI), Visual Spatial Index (VSI), and omnibus Full Scale IQ (FSIQ) stability coefficients exceeded 0.80. Neither intraindividual subtest difference scores nor intraindividual composite difference scores were stable across time (M = 0.26 and 0.36, respectively). Rare and unusual subtest and composite score differences as well as subtest and index scatter at initial testing were unlikely to be repeated at retest (kappa = 0.03 to 0.49). It was concluded that VCI, VSI, and FSIQ scores might be sufficiently stable to support normative comparisons but that none of the intraindividual (i.e. idiographic, ipsative, or person-relative) measures were stable enough for confident clinical decision making.

  • The WISC-V shows adequate convergent and discriminant validity, particularly as a supporting instrument in the assessment of ADHD and other neurodevelopmental difficulties.

    “Likewise, it shows adequate convergent and discriminant validity, particularly as a supporting instrument in the assessment of ADHD and other neurodevelopmental difficulties [37, 38, 39].”

    From ADHD, Subtypes and Cognitive Performance: WISC-V as a Support Tool for Diagnostic Assessment (2026) · cites this paper as [37]

    The Abstract describes the WISC-V as psychometrically sound, and the Summary & conclusions finds the VCI and FSIQ scores sufficiently reliable for clinical use. But the paper studies long-term score stability, not convergent or discriminant validity for assessing ADHD or other neurodevelopmental difficulties; its conclusions also caution against overinterpreting other WISC-V scores. No page numbers are provided in our copy. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Modifying the administration and scoring of the WISC-IV digit span backward subtest reduced its association with fluid reasoning from a significant r=.49 to a non-significant r=.15 and increased its associations with latent working memory (reordering and dual-processing, r=.53-.58) and academic achievement (r=.49).

    “modifications to the subtest administration and scoring decreased its association with fluid reasoning (from a statistically significant r=.49 to a non-significant r=.15) and substantially increased the magnitude of its associations with latent estimates of working memory, specifically reordering and dual-processing (r=.53-.58) and academic achievement (r=.49).129”

  • The modified digit span backward becomes a valid measure of working memory at the point where testing is traditionally discontinued.

    “The results indicated that “digit span backward becomes a valid measure of working memory at exactly the point that testing is traditionally discontinued”.129”

    From Executive function deficits in attention-deficit/hyperactivity disorder and autism spectrum disorder (2024) · cites this paper as [129]

    The Method > Instrument section identifies Digit Span as a WISC-V subtest used in the Working Memory Index, but does not discuss a modified backward task or when testing is discontinued. The Summary & conclusions section addresses long-term score stability, not that claim. Searches for the quoted phrase and for modified digit span backward found no supporting passage in our copy; page numbers were unavailable. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • In children with ADHD, traditional scoring of the WISC-IV digit span backward subtest failed to predict working memory or achievement and showed moderate correspondence with fluid reasoning (general factor g).

    “the results revealed that traditional scoring of the Wechsler Intelligence Scale for Children-IV digit span backward subtest (a commonly used task assumed to test working memory) failed to predict working memory or achievement and instead showed moderate correspondence with fluid reasoning (general factor g)131.”

    From Executive function deficits in attention-deficit/hyperactivity disorder and autism spectrum disorder (2024) · cites this paper as [129]

    The Method (Instrument; Participants & procedure, pages unavailable) describes repeat testing with the WISC-V, including children with ADHD. The Summary & conclusions reports test–retest stability comparisons, not whether traditionally scored WISC-IV Digit Span Backward predicts working memory or achievement or corresponds with fluid reasoning. Searches for those specific terms found no passage addressing the claimed result. (LLM, conf=0.78)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
