Abstract

Objective: To evaluate how distinct presentations of anxiety symptoms and intellectual impairment influence the measurement and estimated rate of clinically significant anxiety in autism spectrum disorder (ASD).Method: The sample included 75 children (ages 9–13 years) with ASD and varied IQ and 52 typically developing (TD) controls and parents. Parents completed anxiety symptom scales and a diagnostic interview, designed to (1) differentiate anxiety and ASD and (2) examine DSM-specified and unspecified (“distinct”) anxiety presentations in each child, including fears of change, special interests, idiosyncratic stimuli and social confusion rather than evaluation. Children completed standard intellectual and ASD diagnostic assessments.Results: 69% of those with ASD had clinically-significant anxiety, including 21% DSM-specified anxiety disorders, 17% distinct anxiety, and 31% both. Only 8% of TD children had clinically-significant anxiety, all DSM-specified. DSM-specified anxiety disorders in children with ASD and intellectual impairment (IQ<70) were predominantly specific phobias. DSM-specified anxiety other than specific phobia was significantly less common in children with, versus without, intellectual impairment; this was not the case for distinct anxiety. The sensitivities of anxiety scales were moderate to poor, particularly in cases with intellectual impairment.Conclusions: ASD is associated with more frequent and varied presentations of clinical anxiety, which may align with and differ from the specified anxiety disorders of the DSM. Standard parent report anxiety scales have reduced sensitivity to detect clinical anxiety in ASD, particularly in children with intellectual impairment.

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.
