This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

Purpose: The purpose of this study was to examine feedback processing within the context of probabilistic learning in children with and without developmental language disorder (DLD). Method: The probabilistic category learning task required 28 children ages 8-13 years old to classify novel cartoon animals that differed in five binary features into…

Restricted and repetitive behaviors (RRB) are observed in young children with intellectual and developmental delays or disabilities (DD) including autism spectrum disorders (ASD). Self-injurious behavior is often considered an extreme form of RRB, but the nature of the relation between SIB and other forms of RRBs is not completely understood.…

Functional communication training (FCT) is highly effective in reducing challenging behavior and increasing appropriate communication in children with developmental disabilities. However, the challenging behavior may re-occur following successful treatment with functional communication training when the functional communication response contacts…

Various types of augmentative and alternative communication systems have been successfully used to enable functional communication in children with developmental disabilities. The effects of such systems on natural speech production have also been investigated, but few studies have explored the effects of specific procedures aim at inducing…

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…

Gender variance (GV) and autism spectrum disorder (ASD) frequently co-occur in clinical populations. We investigated GV in association with ASD characteristics in nonclinical children and in children with developmental/mental health diagnoses. In 6-12-year-olds (N = 2445; 51% birth-assigned boys), the Gender Identity Questionnaire for Children…

Purpose: Research is only beginning to address the extent to which evidence-based parenting programmes have utility and merit within populations of children and families with neurodevelopmental disorders (NDD). The purpose of this paper is to evaluate a parent-focused intervention for families who have a child with a NDD and investigate whether…

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…

This study examined how child problem behaviour could be related to maternal Hwa-Byung (HB; Korean culture syndrome, meaning "anger illness") among Korean mothers of children with developmental disabilities. Acceptance of disabilities and parenting stress were tested as mediators for the relationship between child problem behaviour and…

Executive functioning abilities have been associated with important behaviors such as adaptive skills and cognitive abilities in children with and without disabilities. Executive functioning has primarily been measured as a strong predictor of later abilities in children with neurodevelopmental disabilities, such as attention-deficit/…

Although the early behaviors associated with autism spectrum disorder have been well characterized, many behaviors are also commonly observed in young children with other developmental delays and even in those with typical development. Therefore, consideration must be given to whether a child demonstrates sufficient autism spectrum disorder…

Background: Williams syndrome (WS) phenotype is described as unique and intriguing. The aim of this study was to investigate the associations between speech-language abilities, general cognitive functioning and behavioural problems in individuals with WS, considering age effects and speech-language characteristics of WS sub-groups. Methods: The…

Background: Developmental language disorder (DLD) is common in children, but little is known about its association with quality of life (QoL) in middle childhood. QoL is a complex construct, aligning with an individual's sense of well-being and is related to functional limitations associated with DLD. Biopsychosocial models of disability account…

Playground design is critical to school-based practice, insuring access and use for all children. The play behavior of children with special needs is qualitatively and quantitatively different than their typically developing peers. However, empirical data is needed to support the therapeutic value of playground equipment used with school-aged…
