Editorial: The rising prevalence of autism

Fombonne, Eric·2018·Journal of Child Psychology and Psychiatry

Abstract

The first autism surveys were simple head counts of children already diagnosed with a severe autism phenotype and residing in small, circumscribed geographical areas. Prevalence was low, ranging from 0.4 to 2/1,000 in the 1960's and 1970's. Today, the methodology of surveys has become more complex; studies include large populations, multiple sites, stratified samples and rely on intricate sets of screening activities followed by some form of diagnostic confirmation procedures. Yet, and as surprising as it may be, there is no standardization of autism survey methodology. Each survey has unique design features that reflect the local educational and health services infrastructure and current social policies for children with disabilities, they include or not parents, teachers and subjects with Autism Spectrum Disorder ( ASD ), and rely on variable screening and diagnostic instruments and methods. As such, prevalence differences between studies are hazardous to evaluate and whether observed discrepancies are due to method factors or true differences in population parameters, cannot be determined.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Because records-review surveillance does not involve direct assessment or caregiver interview, it could rely on mechanical rules lacking clinical judgment and overestimate ASD prevalence.

    “Nevertheless, since this design does not involve a direct assessment of a child and a direct interview with a child’s caregivers, this design could rely on mechanical rules in the interpretation of available records, lacking clinical judgment and, as a result, overestimate prevalence estimates of ASD (54, 55).”

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.
