Aggression in children with autism spectrum disorders and a clinic-referred comparison group / Cristan FARMER in Autism, 19-3 (April 2015)

In this multisite study, the Children’s Scale for Hostility and Aggression: Reactive/Proactive and the Aggression subscale of the Child Behavior Checklist were rated for 414 children with autism spectrum disorder (autistic disorder, 69%; pervasive developmental disorder not otherwise specified, 24%; Asperger’s disorder, 7%) and 243 clinic-referred children without autism spectrum disorder, aged 1–21 years (mean age about 7 years). Participants were not selected for aggressive behavior. Relative to the comparison group, children with autism spectrum disorder were reported to have less aggression and were more likely to be rated as reactive rather than proactive. Among all subjects, sex was not associated with aggression; higher IQ/adaptive behavior and older age were associated with more sophisticated types of aggression, while lower scores on IQ, adaptive behavior, and communication measures were associated with more physical aggression. The interaction between demographic variables and diagnosis was significant only for age: younger but not older children with autism spectrum disorder showed less aggression than clinic-referred controls.

Attainment and loss of early social-communication skills across neurodevelopmental conditions in the Norwegian Mother, Father and Child Cohort Study / Alexandra HAVDAHL in Journal of Child Psychology and Psychiatry, 65-5 (May 2024)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 65-5 (May 2024) . - p.610-619 Titre : Attainment and loss of early social-communication skills across neurodevelopmental conditions in the Norwegian Mother, Father and Child Cohort Study Type de document : Texte imprimé et/ou numérique Auteurs : Alexandra HAVDAHL, Auteur ; Cristan FARMER, Auteur ; Pål SUREN, Auteur ; Anne-Siri ØYEN, Auteur ; Per MAGNUS, Auteur ; Ezra SUSSER, Auteur ; W. Ian LIPKIN, Auteur ; Ted REICHBORN-KJENNERUD, Auteur ; Camilla STOLTENBERG, Auteur ; Somer BISHOP, Auteur ; Audrey THURM, Auteur Article en page(s) : p.610-619 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Delays and loss of early-emerging social-communication skills are often discussed as unique to autism. However, most studies of regression have relied on retrospective recall and clinical samples. Here, we examine attainment and loss of social-communication skills in the population-based Norwegian Mother, Father and Child Cohort Study (MoBa). Methods Mothers rated their child's attainment of 10 early-emerging social-communication skills at ages 18 and 36?months (N = 40,613, 50.9% male). Prospectively reported loss was defined as skill presence at 18?months but absence at 36?months. At 36?months, mothers also recalled whether the child had lost social-communication skills. The Norwegian Patient Registry was used to capture diagnoses of Autism Spectrum Disorder (autism) and other neurodevelopmental disabilities (NDDs). Results Delay in at least one skill was observed in 14% of the sample and loss in 5.4%. Recalled loss of social-communication skills was rare (0.86%) and showed low convergence with prospectively reported loss. Delay and especially loss were associated with elevated odds of an autism diagnosis (n = 383) versus no autism diagnosis (n = 40,230; ?3 skills delayed: OR = 7.09[4.15,12.11]; ?3 skills lost: OR = 30.66[17.30,54.33]). They were also associated with an increased likelihood of autism compared to some other NDDs. Delay (relative risk [RR] = 4.16[2.08, 8.33]) and loss (RR = 10.00[3.70, 25.00]) associated with increased likelihood of autism versus ADHD, and loss (RR = 4.35[1.28,14.29]), but not delay (RR = 2.00[0.78,5.26]), associated with increased likelihood of autism compared to language disability. Conversely, delay conferred decreased likelihood of autism versus intellectual disability (RR = 0.11[0.06,0.21]), and loss was not reliably associated with likelihood of autism versus intellectual disability (RR = 1.89[0.44,8.33]). Conclusions This population-based study suggests that loss of early social communication skills is more common than studies using retrospective reports have indicated and is observed across several NDD diagnoses (not just autism). Nevertheless, most children with NDD diagnoses showed no reported delay or loss in these prospectively measured skills.

Disentangling global and domain-level adaptive behavior trajectories among children with autism spectrum disorder / Cristan FARMER in Journal of Child Psychology and Psychiatry, 64-6 (June 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-6 (June 2023) . - p.868-875 Titre : Disentangling global and domain-level adaptive behavior trajectories among children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Cristan FARMER, Auteur ; Audrey THURM, Auteur ; Emma CONDY, Auteur ; Eric DUKU, Auteur ; Peter SZATMARI, Auteur ; Teresa BENNETT, Auteur ; Mayada ELSABBAGH, Auteur ; Connor M.

SMITH, Auteur ; Tracy VAILLANCOURT, Auteur ; Anat ZAIDMAN-ZAIT, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; Stelios GEORGIADES, Auteur Article en page(s) : p.868-875 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Heterogeneity in adaptive behavior abilities among people with autism spectrum disorder (ASD) is expressed not only as uneven levels of impairment across domains, but also in the developmental trajectories of adaptive skills. We studied the question of whether, after accounting for global adaptive behavior development, we find evidence of heterogeneity in the trajectories of specific domains of adaptive behavior. Methods A sample of 504 children with ASD was obtained by combining data from two independent natural history studies conducted in North America. We used a factor of curves model to explain growth between 36 and 138?months in Vineland Adaptive Behavior Scales, Second Edition (VABS) age equivalents as a function of domain-specific and global growth processes. Results The domain-specific trajectories in all three domains (Communication, Daily Living Skills, and Socialization) reflected impairment relative to age expectations as well as slower-than-expected growth with age, and the parameters of these trajectories were moderately-to-strongly correlated across domains. The global adaptive behavior trajectory had an initial (36-41?months of age) developmental level of about 22 age-equivalent months, and eventually slowed after initially increasing by about 6 months each year. The global trajectory accounted for the majority of variance in the domain-level processes; however, additional variance remained (14%-38%) in the domain-level intercepts, slopes, and quadratic processes. Conclusions These results extend existing theoretical and empirical support for the hierarchical structure of adaptive behavior to include its development over time in clinical samples of children with ASD. A latent global trajectory may be sufficient to describe the growth of adaptive behavior in children with ASD; however, the remaining domain-specific variability after accounting for global adaptive behavior development allows for the possibility that differential effects of intervention on specific domains may be possible and detectable.
