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…

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)…

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…

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…

Purpose: The purpose of this study was to compare antipsychotic use by youth with intellectual/developmental disabilities to youth without IDD as they transitioned from pediatric to adult health care services. In addition, antipsychotic use was compared between youth with different types of IDD (autism, Fetal Alcohol Syndrome, Down syndrome and…

Mothers of school-aged children ages 3 to 17 years with developmental disabilities (DDs) commonly report sleep problems in their children associated with impaired maternal sleep. However, existing research relies heavily on mothers' self-reported sleep. This study aimed to determine the feasibility of objectively measuring child and mother…

The transition to adulthood is a significant step in every individual's life. Specifically, for individuals with disabilities, the transition process requires targeted planning for specific adulthood outcomes (e.g., employment, higher education, living skills, social skills, and community preferences). As such, parent and professional voices and…

The COVID-19 pandemic and its demands of social distancing have created challenges in the lives of children/adolescents with developmental disabilities and their families, which would change aspects of children's functioning. The objective of this study was to evaluate changes in some components of functioning of children/adolescents with…

Manding is an important skill for children to learn to access not only preferred items but also information that can be crucial to their success in academic, professional, or social settings. There is a need to continue research to best teach mands for information. The current study examined the effectiveness of using incidental teaching to teach…

This report provides updated prevalence estimates for diagnosed autism spectrum disorder, intellectual disability, and other developmental delay among children 3-17 years from the 2019-2021 National Health Interview Survey, with differences in prevalence examined between years and by sex, age group, and race and Hispanic origin. Estimates are also…

Objective: This study was conducted to explore the effect of motor coordination on repetitive behaviors in children with Autism Spectrum Disorder (ASD) aged 5-15 years. Methods: The study employed the causal-comparative design, one of the correlational survey designs. The study was carried out with data obtained from parents of 241 children with…

Introduction: Mental health concerns have been noted to be highly prevalent for youth with intellectual disability (ID), with or without autism spectrum disorder (ASD). The purpose of the current study was to examine a Canadian sample of youth with ID, with or without ASD, to explore caregiver-reported percentages, predictors, and treatment…

Background & aims: Although the Picture Exchange Communication System (PECS) has been demonstrated to be an effective intervention to teach people diagnosed with autism spectrum disorder a functional communication system, the research indicates variability in PECS outcomes across people and studies. Therefore, the purpose of the current study…

This 10-year study followed 134 caregivers of young adults with autism and intellectual disability, examining the effects of caregivers' coping strategies, sociodemographic features, and young adult symptomatology on caregiver well-being and depression. Lower caregiver education and higher young adult externalizing behaviors predicted lower…
