This study investigated motor skill acquisition in children with ASD (n = 15, 12 males; ages 7-16 years) during iCan Bike Camp, a 1-week, community-based intervention (5 x 75-min sessions) to teach independent bicycle riding. After completing the camp's task-oriented, individualized training program, all participants demonstrated motor skill acquisition on the bicycle, and nine participants rode independently at least 70 feet. Exploratory analyses showed that motor coordination and social communication correlated with rates of skill acquisition. These findings indicate the feasibility and efficacy of brief, community-based motor interventions to teach bicycle riding-an important developmental skill supporting adaptive functioning-to children with ASD.

We previously reported a quantitative, cross-species (human–chimpanzee) social responsiveness measure, which included the development of the Chimpanzee Social Responsiveness Scale (CSRS). Here, we augment our prior CSRS sample with 25 zoo chimpanzees at three sites: combined N = 54. The CSRS demonstrated strong interrater reliability, and low-ranked chimpanzees, on average, displayed higher CSRS scores. The CSRS continues to discriminate variation in chimpanzee social responsiveness, and the association of higher scores with lower chimpanzee social standing has implications for the relationship between autistic traits and human social status. Continued comparative investigations of social responsiveness will enhance our understanding of underlying impairments in ASD, improve early diagnosis, and inform future therapies.

Genetic architecture of reciprocal social behavior in toddlers: Implications for heterogeneity in the early origins of autism spectrum disorder / Natasha MARRUS in Development and Psychopathology, 32-4 (October 2020)

However, the behavioral and genetic architecture of RSB in toddlerhood, when ASD first emerges, has not been fully characterized. We analyzed data from a quantitative video-referenced rating of RSB (vrRSB) in two toddler samples: a community-based volunteer research registry (n = 1,563) and an ethnically diverse, longitudinal twin sample ascertained from two state birth registries (n = 714). Variation in RSB was continuously distributed, temporally stable, significantly associated with ASD risk at age 18 months, and only modestly explained by sociodemographic and medical factors (r2 = 9.4%). Five latent RSB factors were identified and corresponded to aspects of social communication or restricted repetitive behaviors, the two core ASD symptom domains. Quantitative genetic analyses indicated substantial heritability for all factors at age 24 months (h2 ? .61). Genetic influences strongly overlapped across all factors, with a social motivation factor showing evidence of newly-emerging genetic influences between the ages of 18 and 24 months. RSB constitutes a heritable, trait-like competency whose factorial and genetic structure is generalized across diverse populations, demonstrating its role as an early, enduring dimension of inherited variation in human social behavior. Substantially overlapping RSB domains, measurable when core ASD features arise and consolidate, may serve as markers of specific pathways to autism and anchors to inform determinants of autism's heterogeneity.

Mate selection and current trends in the prevalence of autism / Elizabeth FORSEN in Molecular Autism, 15 (2024)  

Public ISBD [article]  inMolecular Autism > 15 (2024) . - 29p. Titre : Mate selection and current trends in the prevalence of autism Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth FORSEN, Auteur ; Natasha MARRUS, Auteur ; Jacqueline JOYCE, Auteur ; Yi ZHANG, Auteur ; John N. CONSTANTINO, Auteur Article en page(s) : 29p. Langues : Anglais (eng) Mots-clés : Adult  Child  Female  Humans  Male  Autistic Disorder/epidemiology/genetics  California/epidemiology  Hispanic or Latino  Missouri/epidemiology  Prevalence  White  Assortative mating  Autism  Autism prevalence  Mate selection  Racial and ethnic minorities  Responsiveness Scale-2, a quantitative measure of autistic traits. The remaining  authors declare that they have no conflict of interest. Index. décimale : PER Périodiques Résumé : BACKGROUND: According to the most recent U.S. CDC surveillance data, the rise in prevalence of childhood autism spectrum disorder among minority children has begun to outpace that of non-Hispanic white children. Since prior research has identified possible differences in the extent of mate selection for autistic traits across families of different ethnicity, this study examined variation in autism related traits in contemporaneous, epidemiologically ascertained samples of spousal pairs representing Hispanic and non-Hispanic white populations. The purpose was to determine whether discrepancies by ethnicity could contribute to differential increases in prevalence in the current generation of young children. METHODS: Birth records were used to identify all twin pairs born between 2011 and 2013 in California and Missouri. Families were selected at random from pools of English-speaking Hispanic families in California and Non-Hispanic White families in Missouri. Autistic trait data of parents was obtained using the Adult Report Form of the Social Responsiveness Scale (SRS-2). RESULTS: We did not identify a statistically significant difference in the degree of mate selection for autism related traits between Hispanic and non-Hispanic white spousal pairs. However, the degree of spousal correlation observed in this recent cohort was pronounced (on the order of ICC 0.45) and exceeded that typically reported in prior research (on the order of 0.30), surpassing also widely reported estimates for sibling correlation (also on the order of 0.30). LIMITATIONS: The sample did not allow for a direct appraisal of change in the magnitude of spousal correlation over time and the ascertainments of trait burden were derived from spouse report. CONCLUSION: Across two epidemiologically ascertained samples of spousal pairs representing Hispanic and non-Hispanic white families across two U.S. states (respectively, California and Missouri), the extent of autism-related trait co-variation for parents of the current generation of young children is substantial and exceeds correlations typically observed for siblings. Given the heritability of these traits and their relation to autism risk, societal trends in the degree of mate selection for these traits should be considered as possible contributors to subtle increases in the incidence of autism over time and across generations.

This follow-up study surveyed child and adolescent psychiatry and general psychiatry program directors to assess (1) the current extent of residency training in autism spectrum disorder/intellectual disability, (2) program director perceptions of educational topics and resident competency in autism spectrum disorder/intellectual disability, and (3) preferred resources to strengthen autism spectrum disorder/intellectual disability training. As in 2009, many child and adolescent psychiatry program directors reported few lecture hours, although current child and adolescent psychiatry residents saw slightly more patients with autism spectrum disorder but not intellectual disability. General psychiatry program directors reported fewer lecture hours in autism spectrum disorder/intellectual disability and fewer patients with autism spectrum disorder than child and adolescent psychiatry program directors. Both child and adolescent psychiatry and general psychiatry program directors recognized the importance of a range of educational topics in autism spectrum disorder/intellectual disability. Child and adolescent psychiatry program directors reported higher resident competency, and lecture hours and patients seen moderately correlated with resident competency. Program directors indicated that online videos and other resources would help improve autism spectrum disorder/intellectual disability training in their programs. Collectively, these findings suggest minimal improvements in autism spectrum disorder/intellectual disability training over the past decade and highlight the urgent need to advance psychiatry training in this field through dissemination of resources.Lay abstractChildren, adolescents, and adults with autism spectrum disorder and intellectual disability experience high rates of co-occurring psychiatric conditions throughout their lifetime. However, there is a shortage of psychiatrists to treat these populations. We evaluated how much education psychiatrists-in-training receive on how to care for individuals with autism spectrum disorder/intellectual disability. We found that in many psychiatry programs, residents receive limited training experiences in autism spectrum disorder/intellectual disability involving lectures and patient contact and that psychiatry program directors would benefit from more resources to strengthen education in autism spectrum disorder/intellectual disability.
