The Behavioral Inflexibility Scale (BIS) is a recently developed measure of behavioral inflexibility, defined as rigid patterns of behavior that contrast with the need to be flexible when the situation calls for it. In this study, we sought to replicate previous findings on the psychometric properties of the BIS in a community sample. Data for…

Kim, Soo Youn; Lecavalier, Luc – Journal of Autism and Developmental Disorders, 2022
The current review examined the use of self-report measures in autistic individuals in the context of psychiatric assessments. It focused on inter-rater agreement, internal consistency, test-retest reliability, and criterion validity with clinical diagnoses. It also gathered information on constructs measured, the nature of the samples, and the…

Bodfish, James W.; Lecavalier, Luc; Harrop, Clare; Dallman, Aaron; Kalburgi, Sahana Nagabhushan; Hollway, Jill; Faldowski, Richard; Boyd, Brian A. – Journal of Autism and Developmental Disorders, 2022
For individuals with autism spectrum disorder (ASD), behavioral inflexibility can affect multiple domains of functioning and family life. 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…

Reliability and Validity of the Pediatric Anxiety Rating Scale Modified for Autism Spectrum Disorder
Maddox, Brenna B.; Lecavalier, Luc; Miller, Judith S.; Pritchett, Jill; Hollway, Jill; White, Susan W.; Gillespie, Scott; Evans, Andrea N.; Schultz, Robert T.; Herrington, John D.; Bearss, Karen; Scahill, Lawrence – Autism: The International Journal of Research and Practice, 2020
Anxiety often co-occurs with autism spectrum disorder, yet there are few valid and reliable instruments for measuring anxiety in youth with autism spectrum disorder. This article describes the modification of the Pediatric Anxiety Rating Scale for youth with autism spectrum disorder and systematic psychometric evaluation in a well-characterized…

Bearss, Karen; Taylor, Christopher A.; Aman, Michael G.; Whittemore, Robin; Lecavalier, Luc; Miller, Judith; Pritchett, Jill; Green, Bryson; Scahill, Lawrence – Autism: The International Journal of Research and Practice, 2016
Anxiety is common in youth with autism spectrum disorder. Despite this common co-occurrence, studies targeting anxiety in this population are hindered by the under-developed state of measures in youth with autism spectrum disorder. Content validity (the extent to which an instrument measures the domain of interest) and an instrument's relevance to…

Kaat, Aaron J.; Lecavalier, Luc; Aman, Michael G. – Journal of Autism and Developmental Disorders, 2014
The Aberrant Behavior Checklist (ABC) is a widely used measure in autism spectrum disorder (ASD) treatment studies. We conducted confirmatory and exploratory factor analyses of the ABC in 1,893 children evaluated as part of the Autism Treatment Network. The root mean square error of approximation was .086 for the standard item assignment, and in…

Restricted interests and repetitive behaviors vary widely in type, frequency, and intensity among children and adolescents with autism spectrum disorder. They can be stigmatizing and interfere with more constructive activities. Accordingly, restricted interests and repetitive behaviors may be a target of intervention. Several standardized…

Kaat, Aaron J.; Lecavalier, Luc – Journal of Autism and Developmental Disorders, 2015
Autism spectrum disorder (ASD) and anxiety frequently co-occur. Research on the phenomenology and treatment of anxiety in ASD is expanding, but is hampered by the lack of instruments validated for this population. This study evaluated the self- and parent-reported Revised Child Anxiety and Depression Scale and the Multidimensional Anxiety Scale in…

Witwer, Andrea N.; Lecavalier, Luc; Norris, Megan – Journal of Autism and Developmental Disorders, 2012
The "Children's Interview for Psychiatric Syndromes-Parent Version" (P-ChIPS) is a structured psychiatric interview designed to assess the presence of psychiatric disorders in children and adolescents. This study examined the reliability and validity of the P-ChIPS in 61 youngsters (6- to 17-years-old) with Autism Spectrum Disorders. Reliability…

Reel, Kristy H.; Lecavalier, Luc; Butter, Eric; Mulick, James A. – Research in Autism Spectrum Disorders, 2012
This study assessed the diagnostic utility of the Pervasive Developmental Disorder Behavior Inventory (PDDBI) in a sample of 84 children aged 3-12 years of age. Forty-two children with ASD were individually matched on age and non-verbal IQ to 42 children with other disabilities and groups were compared on PDDBI subscales and total score. Results…

Norris, Megan; Lecavalier, Luc – Autism: The International Journal of Research and Practice, 2010
The goal of this review was to examine the state of Level 2, caregiver-completed rating scales for the screening of Autism Spectrum Disorders (ASDs) in individuals above the age of three years. We focused on screening accuracy and paid particular attention to comparison groups. Inclusion criteria required that scales be developed post ICD-10, be…

Ghuman, Jaswinder K.; Leone, Sarah L.; Lecavalier, Luc; Landa, Rebecca J. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
We report on the preliminary validity and utility of the "Ghuman-Folstein Screen for Social Interaction" ("SSI"), a measure of social interaction that can serve to screen for autism spectrum disorders (ASDs) in clinical samples of young high-risk children. Caregivers of 350 children (176 younger participants, ages 24-42 months, mean age = 34.1…

Norris, Megan; Lecavalier, Luc – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Youth with intellectual and developmental disabilities (IDD) experience high rates of emotional and behavior problems. The Nisonger Child Behavior Rating Form (NCBRF) is one of the few tools developed to assess these problems in this population. It consists of a 10-item Social Competence section and a 66-item Problem Behavior section. The goal of…

Witwer, Andrea N.; Lecavalier, Luc – Journal of Autism and Developmental Disorders, 2008
The classification of autism spectrum disorders (ASDs) is a topic of debate among clinicians and researchers with many questioning the validity of the distinction among subtypes. This manuscript examines the validity of three ASD subtypes (Autism, Asperger's, and PDDNOS) by reviewing 22 studies published between 1994 and 2006. We reviewed studies…

Snow, Anne V.; Lecavalier, Luc – Journal of Autism and Developmental Disorders, 2011
Studies on the distinction between Autistic Disorder (AD) and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) have been inconclusive. This study examined the validity of PDD-NOS by comparing it to AD and other developmental disorders (DD) on parent-reported behavior problems. Fifty-four children with PDD-NOS were individually…
