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…

Parents of children with autism spectrum disorder (ASD) face higher levels of caregiver strain compared to parents of children with other disabilities. This study examined child clinical features that predict high levels of caregiver strain for 374 parents of children with ASD. Caregiver strain was measured using the Caregiver Strain Questionnaire…

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…

Sukhodolsky, Denis G.; Lecavalier, Luc; Johnson, Cynthia; Smith, Tristram; Swiezy, Naomi; Bearss, Karen; Kalvin, Carla B.; Scahill, Lawrence – Autism: The International Journal of Research and Practice, 2020
Anxiety is a common and impairing problem in children with autism spectrum disorder, but little is known about it in preschool children with autism spectrum disorder. This article reports on the characteristics of anxiety symptoms in young children with autism spectrum disorder using a parent-completed rating scale. One hundred and eighty children…

Harrop, Clare; Dallman, Aaron R.; Lecavalier, Luc; Bodfish, James W.; Boyd, Brian A. – American Journal on Intellectual and Developmental Disabilities, 2021
Behavioral inflexibility (BI) has been highlighted to occur across genetic and neurodevelopmental disorders. This study characterized BI in two common neurogenetic conditions: Fragile X syndrome (FXS) and Down syndrome (DS). Caregivers of children with FXS (N = 56; with ASD = 28; FXS only = 28) and DS (N = 146) completed the Behavioral…

Stratis, Elizabeth A.; Lecavalier, Luc – Journal of Autism and Developmental Disorders, 2017
This study evaluated the magnitude of informant agreement and predictors of agreement on behavior and emotional problems and autism symptoms in 403 children with autism and their typically developing siblings. Parent-teacher agreement was investigated on the "Child Behavior Checklist" (CBCL) and "Social Responsiveness Scale"…

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…

Stratis, Elizabeth A.; Lecavalier, Luc – Journal of Autism and Developmental Disorders, 2015
This study investigated informant agreement on emotional and behavior problems and social skills in youth with autism spectrum disorder or intellectual disability using meta-analytic methods. Forty-nine studies were included, consisting of 107 effect sizes. The mean weighted effect size across all raters and all behaviors was 0.36, reflecting…

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…

The Research Units on Pediatric Psychopharmacology-Autism Network reported additional benefit when adding parent training (PT) to antipsychotic medication in children with autism spectrum disorders and serious behavior problems. The intent-to-treat analyses were rerun with putative predictors and moderators. The "Home Situations…

Restricted and Repetitive Behaviors and Psychiatric Symptoms in Youth with Autism Spectrum Disorders
Stratis, Elizabeth A.; Lecavalier, Luc – Research in Autism Spectrum Disorders, 2013
Children with autism spectrum disorders (ASD) are at high risk for co-occurring psychiatric disorders. Previous research has suggested that restricted and repetitive behaviors (RRB) are associated with symptoms of co-occurring psychiatric disorders in individuals with ASD, but this relationship is not well understood. The current study…

Previously, we adapted the Home Situations Questionnaire to measure behavioral non-compliance in everyday settings in children with pervasive developmental disorders. In this study, we further revised this instrument for use in autism spectrum disorder and examined its psychometric properties (referred to as the Home Situations…

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…

Objective: Many children with pervasive developmental disorders (PDDs) have serious, functionally impairing behavioral problems. We tested whether combined treatment (COMB) with risperidone and parent training (PT) in behavior management is superior to medication alone (MED) in improving severe behavioral problems in children with PDDs. Method:…
