Abstract

Restricted and repetitive behaviors (RRBs) observed during the Autism Diagnostic Observation Schedule [ADOS: Lord et al., 2000] were examined in a longitudinal data set of 455 toddlers and preschoolers (age 8–56 months) with clinical diagnosis of Autism Spectrum Disorders (ASD; autism, n=121 and pervasive developmental disorders—not otherwise specified (PDD‐NOS), n=71), a nonspectrum disorder (NS; n=90), or typical development (TD; n=173). Even in the relatively brief semi‐structured observations, GEE analyses of the severity and prevalence of RRBs differentiated children with ASD from those with NS and TD across all ages. RRB total scores on the ADOS were stable over time for children with ASD and NS; however, typically developing preschoolers showed lower RRB scores than typically developing toddlers. Nonverbal IQ (NVIQ) was more strongly related to the prevalence of RRBs in older children with PDD‐NOS, NS, and TD than younger children under 2 years and those with autism. Item analyses revealed different relationships between individual items and NVIQ, age, diagnosis, and gender. These findings are discussed in terms of their implications for the etiology and treatment of RRBs as well as for the framework of ASD diagnostic criteria in future diagnostic systems.

  • Although the two repetitive-behavior factors are significantly correlated, their different relationships with other characteristics including IQ and age, as well as their different trajectories across development, may suggest that they represent separate constructs.

    “Thus, although these factors are significantly correlated, their different relationships with other characteristics including IQ and age (Bishop et al. 2006; Kim and Lord 2010), as well as their different trajectories across development (Richler et al. 2010), may suggest that they represent separate constructs (Bishop et al. 2013).”

  • The number and intensity of these behaviors are diagnostically useful in discriminating ASD from non-ASD.

    “While the number and intensity of these behaviors are diagnostically useful in discriminating ASD from non-ASD (Kim and Lord 2010), the number, severity, and persistence of these behaviors across development may be important in identifying subgroups within ASD (Bishop et al. 2006).”

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.
