The Role of Trauma Type and Age in the Relation Between Trauma Exposure and Intelligence

McGuire, Austen, Jackson, Yo·2020·Child Maltreatment

Abstract

Experiencing potentially traumatic events (PTEs) is associated with deficits in cognitive functioning for youth. Previous research has demonstrated that PTE type may influence the association between PTE experiences and intelligence, such that IQ scores may differ by the type of PTE experienced. Additionally, mixed findings in the literature suggest that these associations might differ by age. The current study examined the association between PTE type and IQ and how age may moderate this association. In a sample of youth in foster care ( N = 328, M age = 13.25), physical, psychological, and sexual abuse and family PTEs were directly associated with verbal and nonverbal IQ. Age significantly moderated the association between IQ and neglect and academic PTEs. Results suggest that broad PTE grouping methods or failing to account for both maltreatment and general PTEs in samples of youth in foster care may conceal differences in how PTEs relate to intellectual functioning.

  • The finding of decreased trauma exposure and PTSD with higher intelligence is consistent with previous findings and with the association of childhood trauma with lower intelligence.

    “This is consistent with previous findings [29] and with the association of childhood trauma with lower intelligence [40].”

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.
