Relationships between neuropsychological measures of executive function and behavioral measures of ADHD symptoms and comorbid behavior

JONSDOTTIR, S, BOUMA, A, SERGEANT, J, SCHERDER, E·2006·Archives of Clinical Neuropsychology

Abstract

OBJECTIVE: The aim of this study was to examine the relationship between executive functions (EFs), as measured by neuropsychological tests, and symptoms of attention deficit hyperactivity disorder (ADHD) and comorbid behavior, as rated by parents and teachers. As intelligence and language ability are important covariates they were also assessed. METHOD: The sample consisted of 43 children aged 7-11 years who were referred for neuropsychological assessment at a tertiary clinical facility. Most of the children had the diagnosis of ADHD combined or inattentive type. Different aspects of EFs were assessed. RESULTS: EFs were not significantly related to symptoms of ADHD, but only to comorbid symptoms of depression and autistic symptomatology. Language ability rather than EFs best predicted teacher ratings of inattention. CONCLUSIONS: The results of the study do not support the EF theory of ADHD. The importance of screening for comorbid language disorders in children referred for ADHD is emphasized.

    Teachers may be better informants of neuropsychological problems in children than parents.

    “These results are similar to those of previous studies (e.g.Oosterlaan et al., 2005) emphasizing that teachers may be better informants of neuropsychological problems in children than parents.”

    • cites Oosterlaan et al., 2005 source

      The Discussion (p. 13) reports that teacher-rated AD/HD, unlike parent-rated AD/HD, significantly predicted performance on executive-function tasks, with one exception. This supports the comparison for AD/HD-related executive-function deficits, but not the broader claim about neuropsychological problems in children generally. (LLM, conf=0.85)

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.
