Historically, research exploring the literacy experiences of learners with intellectual and developmental disabilities (IDD) has prioritized systematic, multicomponent instruction that emphasizes the development of traditional reading and writing skills. However, this approach may inadvertently facilitate literacy gatekeeping and limit…

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…

Measurement of adaptive skills is important in the diagnosis, intervention planning, and progress monitoring of children with intellectual and developmental disabilities (IDD). Thus, ensuring accurate measurement, including measurement invariance, across children with and without IDD is critical. In this study, we evaluate the measurement…

Background: Parental intellectual disability is considered a risk factor for child removal internationally. In New South Wales, Australia, authorised clinicians are court appointed experts who assess parenting and cognitive capacity in child protection matters. Method: This study examined a sample of 20 assessment orders requesting parenting…

Exercise is necessary for healthy living, yet individuals with intellectual disability (ID) remain strikingly inactive compared with nondisabled peers. To improve this outcome, individuals with ID can exercise independently by self-instructing. Self-instruction is considered a pivotal skill once it generalizes to untrained stimuli. This study used…

The BCBA Task List (5th and 6th Edition) requires behavior analysts are familiar with multiple assessment methods, including tools to assess the function of problem behaviors and assess skill strengths and deficits. Although several studies exist on the assessment of functions using indirect functional assessments, descriptive functional…

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…

Multimorbidity, defined as having two or more chronic health conditions, is associated with elevated polypharmacy and mortality. Autism spectrum disorder is a whole-body chronic health condition in which comorbidities -- in particular co-occurring intellectual disability -- contribute to high clinical heterogeneity, polypharmacy and premature…

Individual education programs (IEPs) are the cornerstone of special education programs. The persistence of poor in- and post-school outcomes for students with significant disabilities highlights the importance of developing well-designed IEPs to address their multifaceted needs. We conducted a content analysis of IEPs for 150 high school students…

The Vineland-3 purports to measure three dimensions of adaptive behavior, but empirical evidence pertaining to its structural validity is lacking. In this study, factor analyses were conducted on the standardization sample data for the comprehensive forms within the 11- to 20-year-old age range. Results did not support the three domain structure…

This study examined the use of a wearable smartwatch-based intervention to support the executive functioning needs of college students with intellectual disability and autism spectrum disorders. The study was designed to address the universal design for learning guidelines and checkpoints for Provide options for Executive Functions. Three students…

Background: The Nisonger Child Behavior Rating Form (NCBRF) allows for the assessment of frequency and severity of challenging behaviours of individuals with ID with one combined rating. However, frequency and severity rating of challenging behaviours may be in disagreement. Therefore, the efficacy of frequency and severity independent ratings for…

Identification procedures for autism spectrum disorders in paediatric settings include screening and routine clinical surveillance. Screening tools are perceived as challenging, and a preference for direct observation has been reported in Ecuadorian paediatric settings. Augmentative observational procedures could prompt the application of…

We examined relationships between measures of adaptive behavior, cognitive ability, and autism symptom severity in 1458 preschool-aged children with autism from the Study to Explore Early Development. While publications commonly describe autistic children as "low-" or "high-functioning" based on cognitive ability, relying…

Introduction: The goal of this study was to examine socialization in adults with intellectual disability in relation to gender, level of intellectual disability, mental illness, and setting type. Methods: The sample consisted of 120 participants (60 males and 60 females), aged between 20 and 56 years, divided into two groups: 1. participants with…
