The clinical similarity among different neuropsychiatric disorders (NPDs) suggested a shared genetic basis. We catalogued 23,109 coding de novo mutations (DNMs) from 6511 patients with autism spectrum disorder (ASD), 4,293 undiagnosed developmental disorder (UDD), 933 epileptic encephalopathy (EE), 1022 intellectual disability (ID), 1094…

One-hundred twenty-four pre-school children referred for assessment to a neuropsychiatric team were included in this study of the Autism Behavior Checklist (ABC), ESSENCE-Q, and Conners Abbreviated Parent-Teacher Rating Scale (CAPRS). All three questionnaires showed a good correlation towards severity of symptoms in ASD. The ABC questionnaire was,…

Students with autism spectrum disorder (ASD) and intellectual disability (ID) may experience challenges when learning tasks that are complex and require numerous steps. This difficulty can lead to employment issues for this population of learners. Therefore, researchers have explored methods to teach employment-related tasks to students with ASD…

We examined special education classifications among students aged 3-21 in North Carolina public schools, highlighting autism spectrum disorder (ASD) and intellectual disability (ID). Results revealed variability by county in ASD and ID prevalence, and in county-level ratios of ID vs. ASD classifications. Sociodemographic characteristics predicted…

Limited research has been done to explore parental perception of stigma. The present study developed the Parental Perceptions of Public Attitudes Scale to examine perceived stigma among Serbian parents of children with autism spectrum disorder (ASD) and children with physical disabilities (PD). The convenience sample consisted of 82 participants.…

Although a sizable minority of students who are deaf or hard of hearing (DHH) are also diagnosed with autism spectrum disorder (ASD), there is little research examining teachers' feelings of aptitude for working with these students, nor the instructional strategies used with this population. This study reports results from a researcher-designed…

We reviewed federal special education data to determine school-identified prevalence of Autism Spectrum Disorder (ASD) and other disability categories by U.S. state. We also examined whether state-level policies, demographic factors, and rates of other eligibility categories are predictive of these state ASD rates. Results indicate that overall, 1…

The processing speed index (PSI) of the Wechsler intelligence scale for children (WISC-IV) has been found to predict a child's level of academic functioning. The consistently reported PSI weakness in children with autism spectrum disorder (ASD) therefore warrants special assistance and attempts at compensation for the disadvantages associated with…

This study investigated the effects of an inclusive physical activity (IPA) program on the motor and social skills and attitudes of students with and without autism spectrum disorder (ASD). The study sample consisted of 45 ASD and typical development (TD) students aged between 6 and 11 years. The students were randomly divided into two groups: a…

Describing the relative severity and change in autism symptoms is crucial for the appropriate characterization of clinical and research populations. The calibrated severity score (CSS) of the Autism Diagnostic Observation Schedule-2 (ADOS-2; Lord et al., 2012) was created to better describe autism symptom severity consistently across different…

The present study explored the shift from understanding to intervention to population impact in the empirical research published in this journal at five points of time over 40 years since the release of DSM-III. Two-thirds of the more than 600 original studies identified involved basic research, a pattern that is consistent with previous analyses…

To evaluate the relationship between the severity of autism, severity of gastrointestinal symptoms and serum zonulin levels as a marker of increased intestinal permeability in children. Serum zonulin levels were determined in 56 children with ASDs and 55 healthy children. The severity of gastrointestinal symptoms and ASD symptoms was assessed with…

Early identification of autism spectrum disorder (ASD) is regarded as crucial for swift access to early intervention and, subsequently, better outcomes later in life. However, current instruments miss large proportions of children who later go on to be diagnosed with ASD, raising a question of what these instruments measure. The present study…

People punish transgressors with different intensity depending if they are members of their group or not. We explore this in a cross-sectional analytical study with paired samples in children with developmental disorders who watched two videos and expressed their opinion. In Video-1, a football-player from the participant's country scores a goal…

Previous data have suggested that parents of boys with autism spectrum disorder (ASD) may rate their sons' generalised anxiety disorder (GAD) more severely than the boys do themselves. However, no reports have been published to date which examine this issue in a girls-only sample. This study investigated the extent and nature of mother-daughter…
