Data from 260 children with autism spectrum disorder, developmental delay, or typical development between the ages of 2 and 12 years were used to evaluate this measure using quality standards for measurement. Overall, the JA Protocol demonstrated good psychometric properties. Recommendations and limitations for use of this measure based on psychometric analysis results are reported.

Development of the Behavioral Inflexibility Scale for Children with Autism Spectrum Disorder and Other Developmental Disabilities / Luc LECAVALIER in Autism Research, 13-3 (March 2020)  

Public ISBD [article]  inAutism Research > 13-3 (March 2020) . - p.489-499 Titre : Development of the Behavioral Inflexibility Scale for Children with Autism Spectrum Disorder and Other Developmental Disabilities Type de document : texte imprimé Auteurs : Luc LECAVALIER, Auteur ; James W. 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. Autism Research published by International Society for Autism Research published by Wiley Periodicals, Inc. 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.

Measuring the Functional Impact of Behavioral Inflexibility in Children with Autism Using the Behavioral Inflexibility Scale: Clinical Interview (BIS-CI) / James W. BODFISH in Journal of Autism and Developmental Disorders, 52-2 (February 2022)

The objective of this study was to develop and validate a clinical interview version of the Behavioral Inflexibility Scale. Trained interviewers conducted interviews with parents of 144 children with ASD and 70 typically developing children (ages: 3-17 years). Using exploratory factor analysis, the Behavioral Inflexibility Scale-Clinical Interview (BIS-CI) was found to be unidimensional. Reliability data indicated the measure was internally consistent (α = 0.80), achieved excellent inter-rater reliability (ICC = 0.97) and test-retest reliability (ICC = 0.87). These findings demonstrate that the BIS-CI is a reliable and valid measure to determine the functional impact of behavioral inflexibility.

A Retrospective Video Analysis of Canonical Babbling and Volubility in Infants with Fragile X Syndrome at 9–12 Months of Age / Katie BELARDI in Journal of Autism and Developmental Disorders, 47-4 (April 2017)

Research suggests early measures of pre-speech development, such as canonical babbling and volubility, can differentiate typical versus disordered development. This study offers a new contribution by comparing early vocal development in 10 infants with Fragile X syndrome and 14 with typical development. Results suggest infants with Fragile X syndrome produce fewer syllables and have significantly lower canonical babbling ratios compared to infants who are typically developing. Furthermore, the particular measures of babbling were strong predictors of group membership, adding evidence regarding the possible utility of these markers in early identification.

Sensory and repetitive behaviors among children with autism spectrum disorder at home / Anne V. KIRBY in Autism, 21-2 (February 2017)  

Public ISBD [article]  inAutism > 21-2 (February 2017) . - p.142-154 Titre : Sensory and repetitive behaviors among children with autism spectrum disorder at home Type de document : texte imprimé Auteurs : Anne V. KIRBY, Auteur ; Brian A. BOYD, Auteur ; Kathryn L. WILLIAMS, Auteur ; Richard A. FALDOWSKI, Auteur ; Grace T. BARANEK, Auteur Article en page(s) : p.142-154 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Atypical sensory and repetitive behaviors are defining features of autism spectrum disorder and are thought to be influenced by environmental factors; however, there is a lack of naturalistic research exploring contexts surrounding these behaviors. This study involved video recording observations of 32 children with autism spectrum disorder (2 12 years of age) engaging in sensory and repetitive behaviors during home activities. Behavioral coding was used to determine what activity contexts, sensory modalities, and stimulus characteristics were associated with specific behavior types: hyperresponsive, hyporesponsive, sensory seeking, and repetitive/stereotypic. Results indicated that hyperresponsive behaviors were most associated with activities of daily living and family-initiated stimuli, whereas sensory seeking behaviors were associated with free play activities and child-initiated stimuli. Behaviors associated with multiple sensory modalities simultaneously were common, emphasizing the multi-sensory nature of children s behaviors in natural contexts. Implications for future research more explicitly considering context are discussed.
