SCARPA, Auteur Article en page(s) : p.1693-1699 Langues : Anglais (eng) Mots-clés : Assessment  Autism spectrum disorder  Female  Repetitive behaviors  Restricted interests  Sex differences Index. décimale : PER Périodiques Résumé : Previous research found repetitive and restricted behaviors (RRBs) were less predictive of Autism Spectrum Disorder (ASD) in females, indicating the diagnostic construct may not adequately describe RRB presentations in females. This mixed-methods study investigated the female presentation of RRBs, namely restricted interests, in a clinic sample of 125 participants (n = 40 female; ages 2-83 years; 75 ASD). RRB severity did not differ between sexes, t = 1.69, p = 0.094, though male participants scored higher on the Restricted Behavior subscale. Qualitatively, females demonstrated a narrower range of restricted interests and expressed them in a socially oriented manner compared to males. The results suggest unique quantitative and qualitative sex differences in RRB profiles that could shed light on the female ASD phenotype.

Child Autism Spectrum Disorder Traits and Parenting Stress: The Utility of Using a Physiological Measure of Parental Stress / R. S. FACTOR in Journal of Autism and Developmental Disorders, 48-4 (April 2018)

S. FACTOR, Auteur ; D. M. SWAIN, Auteur ; A. SCARPA, Auteur Article en page(s) : p.1081-1091 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Heart rate variability  Parenting  Stress reactivity Index. décimale : PER Périodiques Résumé : Caregivers of children with autism spectrum disorder (ASD) report greater stress due to unique parenting demands (e.g.; Estes et al. in Brain Dev 35(2):133-138, 2013). Stress is often studied through self-report and has not been extensively studied using physiological measures. This study compared parenting stress in mothers of children with and without ASD traits. Twenty-seven mother-child dyads participated in an interaction task while measuring mother's heart rate variability (HRV) and mothers self-reported stress levels. Results demonstrated that while self-report and physiological stress measures were not correlated, ASD symptomology did account for HRV change score (i.e., more severe ASD symptoms were positively related to HRV change). This may reflect an atypical coping response. Implications for using physiological indicators for studying parenting stress are explored.

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 et/ou numérique Auteurs : Ligia ANTEZANA, Auteur ; R. S. FACTOR, Auteur ; E. 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 / E. E. CONDY in Journal of Autism and Developmental Disorders, 49-12 (December 2019)

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.

Repetitive behaviors in Autism Spectrum Disorder: Associations with depression and anxiety symptoms / A. MUSKETT in Research in Autism Spectrum Disorders, 68 (December 2019)

The current study examined how restricted and repetitive behaviors or interests (RRBs) may be related to symptoms of depression and anxiety. Participants included 35 children with ASD (29 male, 6 female) between 3 and 14 years. Youth who met clinical cut-off for depression and anxiety demonstrated increased self-injurious behavior compared to peers with ASD who did not meet clinical cut-off. These findings might suggest that self-injurious behaviors may serve as behavioral indicators of heightened negative affect. This could have important implications for assessment of symptoms of anxiety and depression in this population, which is especially critical given that children with ASD often experience language delays and difficulties.
