The goal of this preliminary investigation was to compare demographic and clinical characteristics in a sample of children with likely Social (Pragmatic) Communication Disorder (SCD) (N = 117) to those in children with possible (N = 118) and some (N = 126) SCD traits, other developmental delay (DD) (N = 91) and autism spectrum disorder (ASD) (N =…

Requests for pathological demand avoidance diagnoses have increased over recent years but pathological demand avoidance remains a controversial issue. We undertook a systematic review of peer-reviewed studies of pathological demand avoidance, using standardised appraisal and synthesis methods, to assess how pathological demand avoidance is…

Sleep problems are prevalent in children with neurodevelopmental disabilities and are associated with the expression of restricted and repetitive behaviors (RRBs). Children (n = 57) with autism spectrum disorder (ASD, n = 38) or developmental delay (DD, n = 19) participated in multiple assessments of intellectual ability, ASD symptoms, and RRBs (3…

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…

Challenging behavior exhibited by young children with neurodevelopmental disabilities is known to negatively affect their optimal development and families' quality of life. Although some support exists for English-speaking parents of children with autism who live in high-resource countries, it is scarce for others. Such disparity may also be…

Background: Previous research suggests parents' level of satisfaction with their child's school experience is highly variable. The present author explored school satisfaction in a Canadian sample of parents of children with severe and often complex developmental disabilities. Method: Parents of 185 children completed questionnaires regarding their…

Individuals with Autism Spectrum Disorder (ASD) and/or intellectual and developmental disabilities (DD) often struggle with behavior management and emotion-regulation (ER). In this manuscript, we describe the results of a chart review examining a group treatment program designed to address ER deficits in youth with ASD and/or DD. The intensive…

The DSM-5 features level of support ratings for social communication (SC) and restrictive and repetitive behaviors (RRB) for individuals with autism spectrum disorder (ASD). We contrasted cognitive, adaptive, and autism severity scores across SC and RRB groups for 158 individuals with ASD diagnosed in a developmental disabilities clinic. Roughly…

Young children with developmental delays, neurodevelopmental disorders, or other developmentally atypical presentations are increasingly referred to the mental health system of care because of symptoms that include prolonged tantrums, aggression, anxiety, and sensory processing difficulties. Concerning behaviors can be viewed as constitutional…

Functional Behavior Assessment (FBA) and behavior interventions have been effective in the management of challenging behavior among children with developmental disabilities including autism spectrum disorders. Research suggests the need for valid measurement instruments for verifying, calibrating and scoring competence in FBA and behavior…

Introduction: Although the Aberrant Behavior Checklist (ABC) is one of the most widely used behavioral rating scales among people with developmental disabilities, very few studies have examined the factor structure of the non-English versions. Methods: The construct validity of the Norwegian ABC was examined in a clinical sample of children and…

The external validity of behavioral treatments for elopement (i.e. leaving supervision without permission) remains unclear because studies to date include only small samples (n = 1-3). This study quantified the overall effectiveness of behavioral treatments for elopement by retrospectively examining treatment data from all patients seen for the…

In this study, we explored potential associations among self-injurious behaviors (SIB) and a diverse group of protective and risk factors in children with autism spectrum disorder from two databases: Autism and Developmental Disabilities Monitoring (ADDM) Network and the Autism Speaks-Autism Treatment Network (AS-ATN). The presence of SIB was…

Autism is a neurodevelopmental disorder that affects the functioning of the brain and consequently other areas of development in an unstable and irregular way. There are many therapeutic approaches to autism and one of them is music therapy. Music therapy is a purely therapeutic treatment (Anagnostopoulou & Manti, 2009). It does not seek…

New Zealand has few estimates of the prevalence of autism spectrum disorder and no national registry. The use of administrative data sources is expanding and could be useful in autism spectrum disorder research. However, the extent to which autism spectrum disorder can be captured in these data sources is unknown. In this study, we utilised three…
