J Autism Dev Disord 39(3):521–531, 2009. Moreover, anxiety in ASD is associated with low social motivation (Swain et al. J Autism Dev Disord, 2015. The present study examined social motivation as a mediator between anxiety and RRBs in a sample of 44 children (2–17 years old; 80 % male) with ASD. The relationship between anxiety and IS, but not other RRBs, was partially mediated by social motivation. These findings suggest anxiety is linked to social motivation deficits in children with ASD, which may increase ritualized behaviors and difficulties with changes in routine. Implications are discussed for differing functions and treatment of RRB domains.

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 Auteurs : Cristan FARMER, Auteur ; Audrey THURM, Auteur ; Emma E.

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.

Gender differences in restricted and repetitive behaviors and interests in youth with autism / Ligia ANTEZANA in Autism Research, 12-2 (February 2019)  

Public ISBD [article]  inAutism Research > 12-2 (February 2019) . - p.274-283 Titre : Gender differences in restricted and repetitive behaviors and interests in youth with autism Type de document : texte imprimé Auteurs : Ligia ANTEZANA, Auteur ; R. S. FACTOR, Auteur ; Emma E. CONDY, Auteur ; M. V. STREGE, Auteur ; A. SCARPA, Auteur ; J. A. RICHEY, Auteur Article en page(s) : p.274-283 Langues : Anglais (eng) Mots-clés : gender/female ASD  restricted/repetitive behavior  sex differences Index. décimale : PER Périodiques Résumé : Previous work has found gender differences in restricted and repetitive behaviors and interests (RRBI) for autism spectrum disorder (ASD). Compared to girls, affected boys have increased stereotyped and restricted behaviors; however much less is known about gender differences in other areas of RRBI. This study aims to identify whether specific RRBI (i.e., stereotyped, self-injurious, compulsive, insistence on sameness, ritualistic, and restricted), as measured by item-level data on the Repetitive Behavior Scale-Revised (RBS-R), can distinguish girls from boys with ASD. Participants included 615 individuals with ASD (507 boys; 82.4%), ages 3-18 years of age (M = 10.26, SD = 4.20), who agreed to share data with the National Database for Autism Research (NDAR). Multivariate analysis of variance and discriminant function analysis (DFA) were used to determine whether item-level RBS-R data could correctly classify cases by gender. DFA results suggest that RBS-R items significantly differentiate gender. Strongly differentiating RBS-R items had greater success in correctly classifying affected boys (67.90%) than girls (61.00%). Items that best-discriminated gender were heightened stereotyped behaviors and restricted interests items in boys and compulsive, sameness, restricted, and self-injurious behavior items in girls. This study is the first to find that girls with ASD may have increased compulsive, sameness, and restricted RRBI compared to boys. Additionally, findings support heightened self-injurious behaviors in affected girls. Future research should disentangle whether elevated rates of RRBI in girls are central to the presentation of ASD in girls or an epiphenomenon of the high rates of co-occurring disorders (e.g., anxiety) noted in girls. Autism Res 2019, 12: 274-283 (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This study is the first to examine a comprehensive measure of repetitive behavior in children with autism, with findings of increased compulsive, insistence on sameness, and self-injurious behavior characterizing girls and increased stereotyped and restricted behavior characterizing boys. Future research should determine whether these elevated behaviors in girls are directly part of the autism presentation in girls or symptoms of co-occurring psychopathology. It is important for autism diagnostic measures to best capture the types of repetitive behavior girls may demonstrate.

Maternal Affect During a Challenging Mother-Child Interaction: The Effects of Broad Autism Phenotype and Respiratory Sinus Arrhythmia Reactivity in Mothers of Children With and Without Autism Spectrum Disorder / Emma E.

Broad autism phenotype (BAP) traits are prevalent in family members of children with autism spectrum disorder (ASD). The study investigated whether RSA and BAP traits in mothers of typically developing (TD) children and mothers of children with ASD influence maternal affect. It was hypothesized that these factors would interact to influence mother-child interactions. Twenty-three mother-child dyads participated in a challenging interaction while measuring mother's RSA. Results indicated that mothers of children with ASD show different RSA reactivity than mothers of TD children. Furthermore, preliminary analyses revealed RSA reactivity moderated the relationship between mothers' rigidity and maternal affect during this interaction. Implications for future research and interventions are discussed.

Respiratory Sinus Arrhythmia Predicts Restricted Repetitive Behavior Severity / Emma E. CONDY in Journal of Autism and Developmental Disorders, 47-9 (September 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-9 (September 2017) . - p.2795-2804 Titre : Respiratory Sinus Arrhythmia Predicts Restricted Repetitive Behavior Severity Type de document : texte imprimé Auteurs : Emma E. CONDY, Auteur ; Angela SCARPA, Auteur ; Bruce H. FRIEDMAN, Auteur Article en page(s) : p.2795-2804 Langues : Anglais (eng) Mots-clés : Repetitive behavior  Respiratory sinus arrhythmia  Heart rate variability Index. décimale : PER Périodiques Résumé : In addition to social communication deficits, restricted repetitive behaviors (RRBs) are a key diagnostic feature of autism spectrum disorder (ASD). Dysfunction of the autonomic nervous system (ANS) in ASD has been posited as a mechanism of RRBs; however, most studies investigating ANS activity in ASD have focused on its relation to social functioning. This study used respiratory sinus arrhythmia (RSA) patterns to measure ANS functioning and analyze its relation to RRBs in children with and without an ASD diagnosis. Baseline RSA and RSA reactivity predicted RRB severity and exploratory analyses revealed these measures may be associated with RRB subgroups. These results are discussed in regards to the behavioral literature on RRBs and the benefits of finding biomarkers for these behaviors.
