Wu; Mustafa Sahin – American Journal on Intellectual and Developmental Disabilities, 2025
Developmental domains, such as cognitive, language, and motor, are key concepts of interest in longitudinal studies of intellectual and developmental disabilities (IDD). Normative scores (e.g., IQ) are often used to operationalize performance on standardized tests of these concepts, but it is the interval-distributed person-ability scores that are…

LeJeune, Lauren M.; Lemons, Christopher J. – Journal of Positive Behavior Interventions, 2021
Students with intellectual and developmental disabilities (IDD) require intensive supports, including those that target behavior, to make progress on literacy goals. In this study, we investigated whether computer-assisted instruction (CAI) may be one effective method to decrease challenging behavior and increase academic engagement. Participants…

Potter, Cynthia N.; Wetzel, Jane L.; Learman, Kenneth E. – Journal of Intellectual & Developmental Disability, 2019
Background: This study examined whether a sensory adapted dental environment (SADE) diminished anxiety and agitation in adults with intellectual and developmental disability (IDD) when compared to a routine dental environment (RDE). Method: Agitated behaviours (frequency and duration) were video-taped and anxiety-related physiological measures…

Annamarie Cohen; MaryAnn Demchak – Education and Training in Autism and Developmental Disabilities, 2018
The present study sought to determine if systematically teaching the use of visual supports to three students identified as having moderate to severe disabilities resulted in improved task completion and independence in general education settings. For each participant, a visual support system delineated a multi-step task, which prior to the…

Lindsay, William R.; Steptoe, Lesley; McVicker, Ronnie; Haut, Fabian; Robertson, Colette – Journal of Mental Health Research in Intellectual Disabilities, 2018
In "DSM-5" there has been a move to dimensional personality disorder (PD) diagnosis, incorporating personality theory in the form of the five-factor model (FFM). It proposes an alternative assessment system based on diagnostic indicators and the FFM, while retaining "DSM-IV" categorical criteria. Four individuals with…

Alexander, Ryan M. – ProQuest LLC, 2017
Intelligence tests and adaptive behavior scales measure vital aspects of the multidimensional nature of human functioning. Assessment of each is a required component in the diagnosis or identification of intellectual disability, and both are frequently used conjointly in the assessment and identification of other developmental disabilities. The…

Clark, Megan L. E.; Barbaro, Josephine; Dissanayake, Cheryl – Journal of Autism and Developmental Disorders, 2017
This paper charted the cognitive and behavioural profiles from toddlerhood to middle childhood in 48 children diagnosed with ASD at 24 months. The Mullen Scales of Early Learning (MSEL) was administered at 24- and 48-months and the Wechsler Abbreviated Scale of Intelligence (WASI) at school age. Autism severity was derived using The Autism…

Pamela J. Mims; Carol Stanger; Julie A. Sears; Wendee B. White – Rural Special Education Quarterly, 2018
Increasingly, researchers have successfully identified strategies to promote comprehension to students who are nonreaders. Further research is needed to replicate these promising results. In the current study, we used a multiple probe across participants design to evaluate the effectiveness of an iPad app, which incorporates evidence-based…

Shepley, Sally B.; Spriggs, Amy D.; Samudre, Mark; Elliot, Mary – Journal of Special Education Technology, 2018
This study used a multiple probe across participants design to (a) evaluate the use of system of least prompts to teach students to self-instruct and (b) evaluate the use of a mobile device for a video activity schedule of a functional daily living skill. In baseline, the classroom teacher asked participants to make a snack and collected…

Norbury, Courtenay Frazier; Vamvakas, George; Gooch, Debbie; Baird, Gillian; Charman, Tony; Simonoff, Emily; Pickles, Andrew – Journal of Child Psychology and Psychiatry, 2017
Background: Language development has been characterised by significant individual stability from school entry. However, the extent to which trajectories of language growth vary in children with language disorder as a function of co-occurring developmental challenges is a question of theoretical import, with implications for service provision.…

Jones, Kyle B.; Cottle, Kristina; Bakian, Amanda; Farley, Megan; Bilder, Deborah; Coon, Hilary; McMahon, William M. – Autism: The International Journal of Research and Practice, 2016
This study describes medical conditions experienced by a population-based cohort of adults with autism spectrum disorder whose significant developmental concerns were apparent during childhood. As part of a 25-year outcome study of autism spectrum disorder in adulthood, medical histories were collected on 92 participants (N = 69 males) who were…

Wu, Pei-Fang; Cannella-Malone, Helen I.; Wheaton, Joe E.; Tullis, Chris A. – Focus on Autism and Other Developmental Disabilities, 2016
Two students with developmental disabilities were taught two daily living skills using video prompting with error correction presented on an iPod Touch, and two different fading procedures were implemented. In one fading procedure, individual video clips were merged into multiple larger clips following acquisition of the entire skill. In the…
