Assessment of executive function in ADHD adolescents: contribution of performance tests and rating scales

Open access
Krieger, Virginia, Amador-Campos, Juan Antonio·2018·Child Neuropsychology

Abstract

This study aimed to analyze performance on measures of neuropsychological and behavioral executive functions (EF) in adolescents with attention deficit hyperactivity disorder (ADHD), and to evaluate the utility of performance-based tests for predicting scores on behavioral EF ratings. One hundred eighteen adolescents (75 ADHD and 43 controls) aged 12-16 years performed neuropsychological tests and completed a behavior rating scale of EF. The ADHD group presented significantly lower scores than controls on Full Scale IQ (FSIQ) and all indexes of the WISC-IV, except the verbal comprehension index (VCI). The ADHD group had significantly lower scores on performance-based tests of working memory, planning and inhibition, and on EF rating scales. Scores on the cognitive EF working memory, planning and flexibility modestly predicted performance on behavioral EF. The results suggest that the combined use of performance-based tests and rating scales provides valuable complementary information that can improve the assessment of executive domains in ADHD.

TL;DR

This study compared 75 adolescents with ADHD and 43 controls on performance-based executive function (EF) tests and self-rated behavioral EF. It found ADHD-related weaknesses on several cognitive and behavioral EF domains, but performance tests explained only a small amount of variance in behavioral EF ratings, supporting complementary use of both assessment types.

Key findings

  • Controls had higher Full Scale IQ than both ADHD groups (ADHD-I M = 99.63, ADHD-C M = 103.41, controls M = 109.12), and the ADHD groups also scored lower on WISC-IV working memory and processing speed indexes; verbal comprehension did not differ significantly.
  • On performance-based EF factors, ADHD groups scored below controls on working memory, planning, and inhibition, but not flexibility. Reported effect sizes were η² = .127 for working memory, .097 for planning, .265 for inhibition, and .020 for flexibility.
  • On the CEFI self-report, ADHD groups reported more difficulty than controls on attention, emotion regulation, inhibitory control, organization, planning, self-monitoring, working memory, flexibility, and initiation, with large effects (e.g., organization η² = .476; attention η² = .437). Only emotion regulation significantly separated ADHD-I from ADHD-C, with ADHD-C reporting greater difficulty.
  • Cognitive EF factors weakly predicted behavioral EF ratings. In the ADHD group, working memory predicted emotion regulation (R² = .090) and self-monitoring, flexibility predicted flexibility (R² = .127), and planning predicted self-monitoring; in controls, flexibility predicted attention (R² = .266) and flexibility (R² = .225).

Methods

  • Cross-sectional comparison of 118 adolescents aged 12–16 years: 75 with ADHD (48 ADHD-I, 27 ADHD-C) and 43 controls. ADHD diagnoses followed DSM-5 criteria using a clinical interview, ADHD questionnaire, Conners-3 ratings, and expert panel agreement; controls had low symptom levels.
  • Participants completed the WISC-IV, performance-based EF tasks (including WNV spatial memory, ROCF, Porteus Maze, WCST, TMT, and d2), the CEFI self-report, and Conners-3 DSM scales across three sessions. Medication was suspended for 24 hours before assessment.
  • Analyses included chi-square/ANOVA, MANOVA with Bonferroni or Games-Howell adjustments, Pearson correlations, and hierarchical regression predicting CEFI scales from EF factor scores.

Limitations

  • The paper states that the ADHD group did not include the hyperactive-impulsive presentation, and that the ADHD-C subgroup was smaller than the ADHD-I subgroup, which may have limited detection of small between-group differences.
  • Evident from the text: behavioral EF was assessed only through adolescent self-report on the CEFI, with no parent or teacher CEFI informant ratings, so shared-method variance and self-perception may influence those findings.
  • Evident from the text: the design was cross-sectional, and the ADHD sample had high comorbidity; the authors intentionally did not covary FSIQ or comorbidity, which limits causal and adjusted interpretations.

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.

  • ADHD correlations are called nonsignificant despite reported p-values

    Minor

    The text describes the cognitive-behavioral EF correlations in the ADHD group as nonsignificant, then gives examples marked p < .05.

  • Control correlations are called nonsignificant despite reported p-values

    Minor

    The statement that control-group cognitive-behavioral EF correlations were nonsignificant conflicts with its examples marked p < .05.

  • Discussion omits the reported difference between ADHD presentations

    Minor

    The discussion concludes that the two ADHD presentations did not differ significantly, although it separately reports a significant difference on the CEFI emotion regulation scale.

  • Comorbidity percentages reverse a subset relationship

    Minor

    Adolescents with at least two other disorders must also have at least one. In both ADHD groups, however, the reported percentage with at least two exceeds the percentage with at least one.

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.
