Behavioral correlates to happiness (i.e., indices of happiness) have been used as means of measuring happiness in individuals with developmental disabilities. However, research has not yet evaluated the possibility that indices of happiness/unhappiness (IHUs) may signal the presence of a setting event that could affect other behaviors. The purpose…

Learners with developmental disabilities often encounter difficulties in performing daily activities that involve digital platforms, operating systems, applications, and other digital tools. Considering the growing importance of digital literacy, we examined the effectiveness of the clustered forward chaining (CFC) procedure in teaching digital…

Background: Children and adolescents with language problems have poorer mental health compared with their non-language impaired peers. Less is known about mental health in adults with a history of language problems. This paper presents a systematic review and meta-analysis that addresses this gap in the literature. Specifically, it summarises the…

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…

Autism spectrum disorder (ASD) and Developmental Coordination Disorder (DCD) are distinct clinical groups with overlapping motor features. We attempted to (1) differentiate children with ASD from those with DCD, and from those typically developing (TD) (ages 8-17; 18 ASD, 16 DCD, 20 TD) using a 5-min coloring game on a smart tablet and (2)…

Purpose: Adolescents with developmental language disorder (DLD) are an underserved population. Having DLD affects adolescents' academic and eventual economic success, supporting the need for accurate, clinically feasible DLD screening tools for adolescents. The objective of this review is to identify clinically feasible screening tools for…

We explored factors associated with physical activity (PA) engagement in youth with developmental disabilities (DD) as they transition out of school. We conducted focus group discussions with 44 youth, families, special educators, and therapists to obtain information on PA levels, barriers to being active, and recommendations to improve PA among…

This systematic review aimed to synthesize evidence on aquatic activities compared with land-based activities in motor performance and physical fitness of children and adolescents with autism spectrum disorder, developmental coordination disorder, and attention-deficit hyperactivity disorder. A systematic search was conducted from four electronic…

Background: The COVID-19 pandemic has had a negative impact on the mental health of people with intellectual and developmental disabilities. Numerous pandemic-related stressors experienced by people with intellectual and developmental disabilities may have impacted their ability to thrive, which has been linked to mental health outcomes. The…

Social cognition impairments may explain social, emotional and behavioural difficulties (SEBD) in individuals with Developmental Language Disorder (DLD). In a novel approach, the Social Attribution Task (SAT) was used to examine this association. SAT narratives were coded from 53 participants [n = 26 DLD; n = 27 typical language development (TLD)]…

This study utilized a qualitative constructivist grounded theory methodology to explore the social and friendship experiences of adolescent girls with developmental disabilities (DD). Participants included 12 adolescent girls with DD and 13 parents of adolescent girls with DD. In-depth interviews were conducted with each participant to better…

Background: Tailored sexuality education for adolescents with intellectual and developmental disabilities is a crucial, yet unmet, need as this population is particularly at risk for sexual abuse and victimisation. However, there are no evidence-based interventions to specifically address this need. This paper presents the development of an…

Background: Adolescents and young adults with intellectual and developmental disabilities are at risk of obesity. Parents influence their diet and physical activity behaviours and therefore, can play important roles in weight management. The aims of this qualitative study were to explore parents' experiences assisting their son or daughter to…

We aim to determine the accessibility of gold-standard hearing assessments -- audiogram or auditory brainstem response (ABR) -- during the first 3 months of hearing health care for children with and without developmental disabilities. Electronic health records were examined from children (0-18 years) who received hearing health care at three…

Although caregiving responsibilities and need for support persist and evolve across the life course in families with autistic youth or youth with other developmental disabilities (DDs), little is known about support during their child's adulthood years. Therefore, the present study used a mixed-methods approach to examine change and stability in…
