BODFISH, Auteur ; Clare HARROP, Auteur ; Allison WHITTEN, Auteur ; Desiree R. JONES, Auteur ; Jill PRITCHETT, Auteur ; Richard A. FALDOWSKI, Auteur ; Brian A. BOYD, Auteur Article en page(s) : p.489-499 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  behavior inflexibility  development  measurement  outcome  repetitive behavior Index. décimale : PER Périodiques Résumé : Behavior inflexibility (BI) refers to rigid patterns of behavior that contrast with the need to be adaptable to changing environmental demands. We developed a parent-reported outcome measure of BI for children with autism spectrum disorder (ASD) and other developmental disabilities with a multi-step iterative process. A pool of 62 candidate items was generated through expert panel feedback, review of existing scales and focus groups. A consensus process was used to generate the final 38 items. Parents of 943 children (age range, 3-18 years; average, 11.4 years; 79% boys) with ASD completed an online survey. One hundred thirty-three parents rated their child twice within 3 weeks (average = 16.5 days). A series of factor analyses suggested that the 38 items measured a single construct. Scores had a weak correlation with level of functioning (-0.12) and did not differ based on sex. Scores had a negligible correlation with age (-0.07), although measurement invariance was not supported. The mean total score for the Behavioral Inflexibility Scale (BIS) was normally distributed. Internal consistency was alpha = 0.97 and temporal stability was r = 0.92. Correlations with parent ratings on the subscales of the Repetitive Behavior Scale-Revised varied from 0.48 to 0.89. The correlation with parent ratings on the Social Communication Questionnaire total score was 0.52. Our data show that BI in children with ASD ranges significantly from mild to severe and that the 38-item BIS is valid and reliable. Autism Res 2020, 13: 489-499. (c) 2020 The Authors.

LAY SUMMARY: We developed a parent-completed rating scale of behavior inflexibility (BI) for children with developmental disabilities using a multistep process. The Behavioral Inflexibility Scale (BIS) contains 38 questions rated on a 6-point scale. Parents of 943 children with autism spectrum disorder (ASD) completed an online survey. We examined associations between the BIS and other scales and demographic variables. The BIS is valid and reliable. BI in children with ASD ranges from mild to severe.

Evaluating the Feasibility of The NIH Toolbox Cognition Battery for Autistic Children and Adolescents / Desiree R. JONES in Journal of Autism and Developmental Disorders, 52-2 (February 2022)

While the majority of autistic and TD children completed all four tasks, autistic children experienced greater difficulties with task completion. Across autistic and TD children, performance on NIH-TCB tasks was highly dependent on IQ, but significant performance differences related to ASD diagnosis were found for two of four tasks. These findings highlight the potential strengths and limitations of the NIH-TCB for use with autistic children.

Parent and professional perspectives on behavioral inflexibility in autism spectrum disorders: A qualitative study / Chetna SETHI in Autism, 23-5 (July 2019)

BOYD, Auteur Article en page(s) : p.1236-1248 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  behavioral inflexibility  family functioning and support  qualitative research  repetitive behaviors and interests Index. décimale : PER Périodiques Résumé : Restricted and repetitive behaviors are a core feature of autism spectrum disorder; however, research on the functional impact of these behaviors on the quality of life for individuals with autism spectrum disorder and their families remains scarce. We conducted focus groups with parents of children with autism spectrum disorder and clinicians in order to better characterize the functional impact of behavioral inflexibility, which represents one potential dimensional construct that could account for the breadth of behaviors comprising the restricted and repetitive behavior domain. Transcripts of the focus groups were analyzed using qualitative analysis coding methods to determine parent and clinician beliefs on a range of issues related to behavioral inflexibility including overall impact, types of child behaviors, and strategies for managing behavioral inflexibility. Thematic analysis revealed that parents and clinicians view behavioral inflexibility as an important behavior that impacts multiple areas of functioning, relates to other restricted and repetitive behaviors as well as social communication behaviors, and warrants targeted treatment. Notably, many parents and clinicians emphasized some positive consequences of behavioral inflexibility as well. These findings add crucial insights into the functional impact of behavioral inflexibility and restricted and repetitive behaviors as a whole and suggest that behavioral inflexibility represents an important avenue for future research.

Refining our Understanding of Anxiety in Autistic Youth: Examining the Role of Behavioral Inflexibility / Clare HARROP in Journal of Autism and Developmental Disorders, 54-10 (October 2024)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 54-10 (October 2024) . - p.3620-3629 Titre : Refining our Understanding of Anxiety in Autistic Youth: Examining the Role of Behavioral Inflexibility Type de document : texte imprimé Auteurs : Clare HARROP, Auteur ; James W.

BOYD, Auteur Article en page(s) : p.3620-3629 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Prior research has demonstrated that cognitive inflexibility is associated with anxiety in autistic individuals. Everyday patterns of behavioral inflexibility (e.g. observable inflexible behavior in the context of the need to change or adapt and that is manifested in real-world everyday settings) is common in autism and can be distinguished from performance on discrete cognitive tasks that tap flexible attention, learning, or decision-making. The purpose of this study was to extend this prior work on inflexibility in autism but with measures specifically developed with input from stakeholders (caregivers and clinicians) for autistic youth designed to measure everyday behavioral inflexibility (BI). We characterized anxiety in a large sample of autistic (N = 145) and non-autistic youth (N = 91), ages 3 to 17 years, using the Parent Rated Anxiety Scale for Autism Spectrum Disorder (PRAS-ASD). Further, we sought to understand how BI, measured via the Behavioral Inflexibility Scale (BIS), predicted anxiety compared to other variables known to increase anxiety in youth (chronological age, IQ, autism diagnosis, assigned sex at birth). Autistic youth had higher parent-related anxiety and BI compared to non-autistic youth. BI was the strongest predictor of anxiety scores, irrespective of diagnosis. Overall, our findings highlight the importance of BI to the understanding of anxiety in autistic youth.

Subgrouping Autism Based on Symptom Severity Leads to Differences in the Degree of Convergence Between Core Feature Domains / Allison WHITTEN in Journal of Autism and Developmental Disorders, 48-6 (June 2018)

BODFISH, Auteur Article en page(s) : p.1908-1919 Langues : Anglais (eng) Mots-clés : Autism  Autism core features  Phenotype Index. décimale : PER Périodiques Résumé : Existing models of autism spectrum disorder (ASD) disagree as to whether the core features should be conceptualized as convergent (related) or divergent (unrelated), and the few previous studies addressing this question have found conflicting results. We examined standardized parent ratings of symptoms from three domains (social, communication, repetitive behaviors) in large samples of typically developing children, children with ASD, and ASD subgroups. Our results suggest that the most evidence for divergence lies in typically developing children and lower severity ASD cases, while more evidence for convergence is found in a subset of cases with more severe impairment on any core feature. These results highlight the importance of subgrouping ASD given the degree of phenotypic heterogeneity present across the autism spectrum.
