Abstract

Background: The range of outcomes for young adults with Autism Spectrum Disorders ( ASD ) and the early childhood factors associated with this diversity have implications for clinicians and scientists. Methods: This prospective study provided a unique opportunity to predict outcome 17 years later for a relatively large sample of children diagnosed with ASD at 2 years old. Diagnostic and psychometric instruments were administered between 2 and 19 with data from 2, 3, and 19 included in this study. Clinicians administered tests without knowledge of previous assessments whenever possible. Caregivers provided additional information through questionnaires. Results: Significant intellectual disabilities at 19 were predicted by age 2 about 85% of the time from VIQ and NVIQ scores together, though prediction of young adult outcome for youths with average or higher intelligence was more complex. By 19, 9% of participants had largely overcome core difficulties associated with ASD and no longer retained a diagnosis. These youths with Very Positive Outcomes were more likely to have participated in treatment and had a greater reduction in repetitive behaviors between age 2 and 3 compared to other Cognitively Able youths ( VIQ ≥70) with ASD . Very Positive Outcome youths did not differ phenotypically from Cognitively Able ASD individuals at 2 but both groups differed from Cognitively Less Able individuals ( VIQ <70). Conclusion: Those most at risk for intellectual disabilities and ASD can be reliably identified at an early age to receive comprehensive treatment. Findings also suggest that some cognitively able children with ASD who participate in early intervention have very positive outcomes, although replication with randomized, larger samples is needed. In order to improve understanding of very positive outcomes in ASD , future research will need to identify how variations in child characteristics and environmental factors contribute to the nature and timing of growth across individuals and areas of development.

  • Although it is possible to identify some children with ASD before parents or professionals have identified concerns, diagnosis is missed in many children, and most tested cohorts have not been systematically followed up to identify later-onset ASD in children who initially tested negatively.

    “In addition, although it is possible to identify some children with ASD before parents or professionals have identified concerns, diagnosis is missed in many children 147 , and most tested cohorts have not been systematically followed up to identify later-onset ASD in children who initially tested negatively 148”

  • Language skills and IQ (nonverbal at early ages; verbal at later ages) are the strongest predictors of outcome both in naturalistic studies and in response to treatment.

    “Nevertheless, language skills and IQ (nonverbal at early ages; verbal at later ages) are the strongest predictors of outcome both in naturalistic studies (Anderson et al. 2014) and in response to treatment (Beglinger & Smith 2005, Howlin et al. 2004, Sallows & Graupner 2005).”

    From Recent Advances in Autism Research as Reflected in DSM-5 Criteria for Autism Spectrum Disorder (2015) · cites this paper as Anderson et al. 2014

    The Results (Cognitively Able vs. Cognitively Less Able Youths; page unavailable) identify childhood IQ as the best predictor of the age-19 IQ group: verbal and nonverbal IQ together at age 2, and verbal IQ alone at age 3. The paper does not establish language skills as a separate strongest predictor, and its strongest-predictor finding concerns later IQ grouping rather than young-adult outcomes generally. The treatment-response portion of the sentence is attributed to other citations, not Anderson et al. (LLM, conf=0.86)

  • IQ and language level are closely tied to overall functioning and outcome in ASD.

    “IQ and language level are closely tied to overall functioning and outcome in ASD (Anderson et al. 2014, Howlin et al. 2013), so for practical purposes, knowing an individual's IQ and functional language ability usually serves as a reasonable proxy for how severely affected the individual is.”
  • Social communication deficits show significant abatement over time for some individuals with ASD.

    “social communication deficits, which show significant abatement over time for some individuals with ASD (Anderson et al. 2014, Shattuck et al. 2007).”
  • Early evaluation, diagnosis, and evidence-based interventions could enhance short-term and long-term developmental outcomes for young children with ASD.

    “Early routine screening for ASD and other developmental concerns is recommended by the American Academy of Pediatrics (1) because early evaluation, diagnosis, and evidence-based interventions could enhance short-term and long-term developmental outcomes for young children with ASD (2–6).”

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.
