Background: Atypical speech prosody has been commonly found among autistic children. Yet it remains unknown whether prosody impairment originates from poor pitch ability in general or whether it is the result of the difficulty in understanding and using prosody for communicative purposes. Aims: To investigate whether native Mandarin…

Population-based research can identify eligibility patterns across e disabilities and cultures, and the Head Start ECLKC gathers relatively controlled data of students in the United States (U.S.) and Puerto Rico, providing an opportunity to directly compare cultures. We compared preschool diagnostic eligibility categories in the U.S. and Puerto…

Purpose: Cluttering is a fluency disorder that has been noted clinically in individuals with fragile X syndrome (FXS). Yet, cluttering has not been systematically characterized in this population, hindering identification and intervention efforts. This study examined the rates of cluttering in male young adults with FXS using expert clinical…

Purpose: Chromosome 16p11.2 deletion syndrome (OMIM #611913) is a rare genetic condition resulting from the partial deletion of approximately 35 genes located at Chromosome 16. Affected people exhibit a variable clinical profile, featuring mild dysmorphisms, motor problems, developmental delay, mild intellectual disability (ID), socialization…

Sotos syndrome is a congenital overgrowth syndrome associated with intellectual disability. This study investigated communicative abilities of children with Sotos syndrome (n = 31), using the Children's Communication Checklist, second edition. A cross-syndrome approach was used to establish the specificity of these abilities. Children with…

Objectives: This paper explores the relationship between speech therapy intensity and parent satisfaction with speech therapy (ST) in children with Phelan-McDermid Syndrome (P-MS), a rare genetic disorder. Methods: ST intensity ("ST Dose [minutes per session]") × ("ST Dose Frequency") × ("ST Length [years]") and…

Background: Individuals with intellectual disability (ID) often demonstrate speech impairments and reduced intelligibility. However, traditional treatment methods, which involve using repetitive verbal and non-verbal exercises, may not be fully suitable for this population. As adults with ID tend to lose interest and motivation facing the demands…

Much research has documented the elevated levels of stress experienced by families of autistic children. Yet remarkably little research has examined the types of support that these families perceive to be beneficial to their lives. This study, co-produced by researchers and school-based professionals, sought to establish these families' support…

Epilepsy is reported to co-occur in individuals with autism spectrum disorder (ASD). Previous studies across the world have found prevalence estimates ranging from 4 to 38%. We examined parent-reported prevalence of co-occurring epilepsy and ASD in the most recent U.S. National Survey of Children's Health, 2011-2012. All analyses accounted for…

The overrepresentation of youth with disabilities in the juvenile justice system is a persistent concern, but estimates of their involvement vary dramatically due to differences in how disability is conceptualized and when involvement in juvenile justice is measured. This study linked juvenile court and educational records for 230,760 students in…

Meaningfully synthesizing single case experimental data from intervention studies comprised of individuals with low incidence conditions and generating effect size estimates remains challenging. Seven effect size metrics were compared for single case design (SCD) data focused on teaching speech generating device use to individuals with…

The purpose of this study was to find out the effectiveness of phonological awareness intervention programs. Computerized databases, including ERIC, PubMed, ProQuest Education Journals, and SCOPUS, were searched using the following search strategy: ("phonological awareness") AND (impairment OR intervention OR training programme). The…

These are the appendixes for the report, "College Enrollment and Completion among Texas High School Graduates with a Disability." The study used student-level administrative data from Texas, available through the data repository at the Texas Education Research Center at the University of Texas. The data repository contains administrative…

In response to concerns raised by Texas higher education stakeholders about the limited information available on students with a disability who are attending college in the state, this study examined college enrollment and completion among Texas public high school graduates by disability status, student demographic characteristics, and primary…
