Abstract

Though often conflated with face validity, ecological validity refers to the degree that a test or measure predicts real-world behavior/functioning. The current study leveraged two independent samples to provide a critical evaluation of the extent to which clinic-based actigraphy demonstrates ecological validity evidence relative to parent- and teacher-reported hyperactivity ratings. Further, across both samples we evaluated the extent to which the ecological validity evidence for these mechanical measures of hyperactivity varies as a function of the task children are completing while their movement is assessed objectively (low vs. high cognitive demands). Across two independent samples comprising clinically-evaluated children with and without ADHD (Ns = 88, 184; Mages = 9.2, 10.4; 6%, 33% girls; 68%, 70% White Non-Hispanic), latent path models indicated that clinic-based actigraphy during visuospatial working memory testing (high cognitive demands) demonstrated significant associations with both parent- and teacher-rated hyperactivity that were indistinguishable (p > .05) from parent and teacher ratings’s associations with each other in both sample 1 (r = .57) and sample 2 (r = .35; all p < .001). Actigraphy during baseline (low cognitive demand) conditions also uniquely predicted hyperactivity at home and school in both samples (all p < .001), albeit with a less consistent yet robust pattern relative to parent/teacher associations. In both samples, actigraphy showed strong test–retest reliability over 2–4 weeks across clinic-based tasks with high cognitive demands (r = .61-.93) and high concurrent validity across tasks with high vs. low cognitive demands (r = .35-.61; all p < .007). This pattern supports the ecological validity of clinic-based actigraphy during working memory testing, which predicts real-world behavior at home and school just as well as parent perceptions of hyperactivity at home predict teacher perceptions of hyperactivity at school (and vice versa).

    The visual hyperactivity factor in that study showed strong convergent validity with actigraph data.

    “In that study, a bifactor model emerged for both informants consisting of two uncorrelated factors – visual hyperactivity and verbal intrusiveness – and showed superior fit relative to a correlated factors model, as well as strong convergent validity between the visual hyperactivity factor and collected actigraph data (Kofler et al., 2020).”

      The Results (Tier 3: Structural Models; page not provided) report significant associations between parent- and teacher-rated visual hyperactivity and actigraph-measured baseline activity. The correlations were modest (r=.25–.27), however, and associations with task-specific activity were not consistent, so describing the convergent validity as strong overstates the findings.

      The Discussion reports approximately 70% overlap between ADHD and non-ADHD activity levels under high-stimulation, low-cognitive-load conditions, supporting 'largely indistinguishable.' But the Results (Worst case estimation) find a statistically significant difference (d = 0.44), so the source does not support saying the groups cannot be reliably distinguished at all.

    Children with ADHD and typically developing children both move significantly more during tasks with high cognitive demands than during tasks with low cognitive demands.

      The Results section (Activity Level: ADHD vs. Typically Developing Group Comparisons; page unavailable) reports a significantly larger ADHD–TD activity difference during high- than low-cognitive-demand conditions.

    The perception that clinic-based actigraphy has poor ecological validity likely partly reflects the common practice of measuring movement mainly during low cognitive demand tasks.

    “(c) the common practice of measuring children’s motor movement via actigraphy primarily during repetitive/monotonous activities or tasks with low cognitive demands that evoke comparatively lower levels of movement than those observed in educational settings (for review, see Kofler et al., 2016).”
    Quote in the paperSubstantial claim1 of 1 sources checked
    • cites Kofler et al., 2016 source

      The Methods section (Coding of Moderators; page unavailable) distinguishes low-demand activities from classroom schoolwork, and the Results show that cognitive demands affect measured ADHD–control differences in activity. But those results do not establish that clinic-based actigraphy is commonly conducted mainly during low-demand tasks or that such tasks produce less movement than educational settings; the reported low-demand and classroom effect sizes did not differ significantly. The paper therefore supports the relevance of task demands, not the full explanation attributed to it. (LLM, conf=0.84)

    Parent and teacher ratings are the accepted benchmark for measuring excessive motor movement in children with ADHD in clinical and diagnostic work and for tracking treatment outcomes.

    Parent and teacher ratings reflect children's behavior in real-world settings.

    “informant ratings were the apt comparison given that they are considered to reflect behavior in real-world settings”

    Actigraphy during working memory tasks measures hyperactivity.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Discussion gives different mean ages for both samples

    Minor

    The discussion reports mean ages of 9.4 and 10.2 years, but the participant descriptions report 9.63 and 10.40 years. Neither pair agrees at the stated precision.

  • Age associations are described as having opposite directions

    Minor

    The limitations section says the age associations differed in direction across samples. The sensitivity results instead give negative age coefficients in both samples: older children had lower, not higher, measured hyperactivity where associations were significant.

  • Sample 1 mean age differs between the abstract and Methods

    Minor

    The abstract gives Sample 1's mean age as 9.2 years, whereas the participant description gives 9.63 years. These cannot be the same mean rounded to one decimal place.

  • Reported cross-method correlation range excludes a reported result

    Minor

    The discussion summarizes cross-method correlations as .35-.57, but the Sample 2 results report a teacher-rating/phonological-actigraphy correlation of .21.

  • Discussion understates Sample 2's age range

    Minor

    The limitations section says both samples were aged 8-12, but the participant description gives an 8-13 range for Sample 2.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

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.
