This study provided the largest exploration to date of the relationship between Repetitive Motor Behaviours, Rigidity/Insistence on Sameness and Circumscribed Interests with other individual characteristics in newly diagnosed individuals with ASD. METHOD: Participants (N = 3,647; 17.7% females; Mage = 6.6 years [SD = 4.7]) were part of the Western Australian (WA) Register for ASD, an independent, prospective collection of demographic and diagnostic data of newly diagnosed cases of ASD in WA. Diagnosticians rated each of the DSM-IV-TR criteria on a 4-point Likert severity scale, and here we focused on the Repetitive Motor Behaviours, Insistence on Sameness and Circumscribed Interests symptoms. RESULTS: The associations between RRB domains, indexed by Kendall's Tau, were weak, ranging from non-significant for both Circumscribed Interests and Repetitive Motor Behaviours to significant (.20) for Insistence on Sameness and Repetitive Motor Behaviours. Older age at diagnosis was significantly associated with lower Circumscribed Interests and significantly associated with higher Insistence on Sameness and Repetitive Motor Behaviours. Male sex was significantly associated with higher Repetitive Motor Behaviours but not Insistence on Sameness or Circumscribed Interests. CONCLUSIONS: The pattern of associations identified in this study provides suggestive evidence for the distinctiveness of Repetitive Motor Behaviours, Insistence on Sameness and Circumscribed Interests, highlighting the potential utility of RRB domains for stratifying the larger ASD population into smaller, more phenotypically homogeneous subgroups that can help to facilitate efforts to understand diverse ASD aetiology and inform design of future interventions.

Does perinatal exposure to exogenous oxytocin influence child behavioural problems and autistic-like behaviours to 20 years of age? / A. J. GUASTELLA in Journal of Child Psychology and Psychiatry, 59-12 (December 2018)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 59-12 (December 2018) . - p.1323-1332 Titre : Does perinatal exposure to exogenous oxytocin influence child behavioural problems and autistic-like behaviours to 20 years of age? Type de document : Texte imprimé et/ou numérique Auteurs : A. J. GUASTELLA, Auteur ; Matthew N. COOPER, Auteur ; C. R. H. WHITE, Auteur ; M. K. WHITE, Auteur ; C. E. PENNELL, Auteur ; Andrew J. O. WHITEHOUSE, Auteur Article en page(s) : p.1323-1332 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  behaviour problems  developmental psychopathology  empathy  public health Index. décimale : PER Périodiques Résumé : BACKGROUND: The neuropeptide and hormone oxytocin is known to have a significant impact on social cognition and behaviour in humans. There is growing concern regarding the influence of exogenous oxytocin (OT) administration in early life on later social and emotional development, including autism spectrum disorder (ASD). No study has examined offspring development in relation to the dose of exogenous oxytocin administered during labour. METHODS: Between 1989 and 1992, 2,900 mothers were recruited prior to the 18th week of pregnancy, delivering 2,868 live offspring. The Child Behaviour Checklist was used to measure offspring behavioural difficulties at ages 5, 8, 10, 14 and 17 years. Autism spectrum disorder was formally diagnosed by consensus of a team of specialists. At 20 years, offspring completed a measure of autistic-like traits, the Autism Spectrum Quotient (AQ). Oxytocin exposure prior to birth was analysed using categorical and continuous approaches (maternal oxytocin dose) with univariate and multivariate statistical techniques. RESULTS: Categorical analyses of oxytocin exposure prior to birth demonstrated no group differences in any measures of child behaviour. A small in magnitude dose-response association was observed for clinically significant total behaviour symptoms (adjusted odds ratio 1.03; 95% CI: 1.01-1.06, p < .01). Exogenous oxytocin administration prior to birth was not associated with ASD (OR: 0.64; 95% CI: 0.15-2.12, p = .46) or high levels of autistic-like traits (p = .93), as assessed by the AQ. CONCLUSIONS: This study is the first to investigate longitudinal mental health outcomes associated with the use of oxytocin-based medications during labour. The results do not provide evidence to support the theory that exogenous OT has a clinically significant negative impact on the long-term mental health of children.

Evidence of a reduction over time in the behavioral severity of autistic disorder diagnoses / Andrew J. O. WHITEHOUSE in Autism Research, 10-1 (January 2017)

This study examined whether there were changes over time in the qualitative and quantitative phenotype of individuals who received the diagnosis of Autistic Disorder. Data were from a prospective register of new diagnoses in Western Australia (n?=?1252). From 2000 to 2006, we examined differences in both the percentage of newly diagnosed cases that met each criterion as well as severity ratings of the behaviors observed (not met, partially met, mild/moderate and extreme). Linear regression determined there was a statistically significant reduction from 2000 to 2006 in the percentage of new diagnoses meeting two of 12 criteria. There was also a reduction across the study period in the proportion of new cases rated as having extreme severity on six criteria. There was a reduction in the proportion of individuals with three or more criteria rated as extreme from 2000 (16.0%) to 2006 (1.6%), while percentage of new cases with no “extreme” rating on any criteria increased from 58.5% to 86.6% across the same period. This study provides the first clear evidence of a reduction over time in the behavioral severity of individuals diagnosed with Autistic Disorder during a period of stability in diagnostic criteria. A shift toward diagnosing individuals with less severe behavioral symptoms may have contributed to the increasing prevalence of Autistic Disorder diagnoses.

Investigating associations between birth order and autism diagnostic phenotypes / Gail A. ALVARES in Journal of Child Psychology and Psychiatry, 62-8 (August 2021)

First- and later-born children have been linked to an increased likelihood of an Autism Spectrum Disorder (ASD) diagnosis, with a smaller body of evidence implicating decreases in cognitive functioning with increased birth order. The present study investigated the potential association between birth order and ASD diagnostic phenotypes in a large and representative population sample. METHODS: Data were obtained from an ongoing prospective diagnostic registry, collected between 1999 and 2017, including children (1-18 years of age, n = 5,404) diagnosed with ASD in the state of Western Australia. Children with ASD were ranked relative to sibling's birth to establish birth order within families at time of ASD diagnosis. Information reported to the registry by health professionals at the time of diagnostic evaluation included demographic and family characteristics, functional abilities and intellectual capacity. RESULTS: Adaptive functioning and intelligence scores decreased with increasing birth order, with later-born children more likely to have an intellectual disability. Compared to first-born children with siblings, first-born children without siblings at the time of diagnosis also exhibited decreased cognitive functioning. CONCLUSIONS: These findings demonstrate for the first time an association between increasing birth order and variability in ASD clinical phenotypes at diagnosis, with potential evidence of reproductive curtailment in children without siblings. Taken together, these findings have significant implications for advancing understanding about the potential mechanisms that contribute to heterogeneity in ASD clinical presentations as a function of birth order and family size.

This RCT evaluated the efficacy of one technology-based early intervention programme (Therapy Outcomes By You; TOBY) in young children with ASD. Methods TOBY is an app-based learning curriculum designed for children and parents as a complement to early behavioural intervention. Eighty children (16 female) were recruited to this RCT within 12 months of receiving a diagnosis of ASD (M age = 3.38; SD = 0.69) and randomised to receive either treatment-as-usual (community-based intervention, n = 39) or the TOBY therapy (at least 20 min/day) plus treatment-as-usual (n = 41) for a period of 6 months. Outcomes were assessed at 3 and 6 months postbaseline. (Australian New Zealand Clinical Trials Registry: ACTRN12614000738628; www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=365463). Results Children in the TOBY intervention group averaged 19 min/day engaging with the app in the first 3 months, but only 2 min/day during the second 3 months. There was no group difference in scores on the primary outcome, the Autism Treatment Evaluation Checklist, at either the 3- or 6-month follow-up. However, significant improvements at the 6-month follow-up were observed in the TOBY intervention group relative to the treatment-as-usual group on three secondary outcomes: the Fine Motor and Visual Reception subscales of the Mullen Scale of Early Learning and the Total Words Understood scale of the MacArthur-Bates Communicative Development Index. Statistical trends towards improvement in the TOBY intervention group were observed on measures of adaptive function, although these decreased in magnitude from the 3- to 6-month follow-up. Conclusions This study provides evidence that technology-based interventions may provide a relatively low-cost addition to existing therapist-delivered interventions for children with ASD. However, sustained use of the app over the full 6-month period was a challenge for most families.
