Background: Since the DSM-5, adaptive functioning has taken a prominent place in the classification of intellectual disability (ID). The ADAPT was developed to assess adaptive skills in individuals with ID. Method: A total of 2,081 ADAPTs from clients with suspected ID or borderline intellectual functioning and 129 ADAPTs from people from the…

Walker, Brooke – ProQuest LLC, 2018
Assessing higher-level verbal repertoires of individuals with autism and related intellectual disabilities is crucial due to the language and cognitive deficits experienced by this population as well as is the need for valid assessment tools for data-driven and individualized treatment. In addition to, curricula or instructional protocols that…

Bauminger-Zviely, Nirit; Shefer, Analia – Autism: The International Journal of Research and Practice, 2021
Peer interaction can be challenging in autism spectrum disorder, but naturalistic peer-observation scales for preschoolers are scarce. This study examined psychometric qualities of the newly developed Autism Peer Interaction Observation Scale. We tested the Autism Peer Interaction Observation Scale to (a) characterize peer interactions of…

Ettlinger, Marc; Morgan-Short, Kara; Faretta-Stutenberg, Mandy; Wong, Patrick C. M. – Cognitive Science, 2016
Artificial language learning (ALL) experiments have become an important tool in exploring principles of language and language learning. A persistent question in all of this work, however, is whether ALL engages the linguistic system and whether ALL studies are ecologically valid assessments of natural language ability. In the present study, we…

This study assessed the reliability and criterion-related validity of teacher ratings on the Adapted Skillstreaming Checklist for a sample of 133 children, aged 6-11 years, with autism spectrum disorder (without intellectual disability). Internal consistency for the total sample was 0.93. For a subsample, test-retest reliability was very good (r =…

Brewer, Neil; Young, Robyn L.; Barnett, Emily – Journal of Autism and Developmental Disorders, 2017
Deficits in Theory of Mind (ToM)--the ability to interpret others' beliefs, intentions and emotions--undermine the ability of individuals with Autism Spectrum Disorder (ASD) to interact in socially normative ways. This study provides psychometric data for the Adult-Theory of Mind (A-ToM) measure using video-scenarios based in part on Happé's…

Green, Adam E.; Kenworthy, Lauren; Gallagher, Natalie M.; Antezana, Ligia; Mosner, Maya G.; Krieg, Samantha; Dudley, Katherina; Ratto, Allison; Yerys, Benjamin E. – Autism: The International Journal of Research and Practice, 2017
Analogical reasoning is an important mechanism for social cognition in typically developing children, and recent evidence suggests that some forms of analogical reasoning may be preserved in autism spectrum disorder. An unanswered question is whether children with autism spectrum disorder can apply analogical reasoning to social information. In…

Scattone, Dorothy; Raggio, Donald J.; May, Warren – Journal of Autism and Developmental Disorders, 2012
The concurrent validity of the KBIT-2 Nonverbal IQ and Leiter-R Brief IQ was evaluated for two groups of children: those with high functioning autism and those with language impairments without autism. Fifty-three children between the ages of 4 and 13 years of age participated in the study. The correlation between the scales was large (r = 0.62)…

Stolarski, Maciej; Zajenkowski, Marcin; Meisenberg, Gerhard – Intelligence, 2013
The relationships between national personality traits and intelligence from 51 countries were examined. It was found that extraversion, openness to experience and agreeableness measured at the national level were significantly and positively correlated with national IQs; however, in the regression model only the former two were marginally…

Bishop, Somer L.; Hus, Vanessa; Duncan, Amie; Huerta, Marisela; Gotham, Katherine; Pickles, Andrew; Kreiger, Abba; Buja, Andreas; Lund, Sabata; Lord, Catherine – Journal of Autism and Developmental Disorders, 2013
Research suggests that restricted and repetitive behaviors (RRBs) can be subdivided into Repetitive Sensory Motor (RSM) and Insistence on Sameness (IS) behaviors. However, because the majority of previous studies have used the Autism Diagnostic Interview-Revised (ADI-R), it is not clear whether these subcategories reflect the actual organization…

To examine the inter-rater reliability of Autism Diagnostic Interview-Revised, Japanese Version (ADI-R-JV), the authors recruited 51 individuals aged 3-19 years, interviewed by two independent raters. Subsequently, to assess the discriminant and diagnostic validity of ADI-R-JV, the authors investigated 317 individuals aged 2-19 years, who were…

Ready, Rebecca E.; Chaudhry, Maheen F.; Schatz, Kelly C.; Strazzullo, Sarah – Journal of Learning Disabilities, 2013
There are few tests that assess reading comprehension in adults, but these tests are needed for a comprehensive assessment of reading disorders (RD). "The Nelson-Denny Reading Test" (NDRT) has a long-passage reading comprehension component that can be used with adolescents and adults. A problem with the NDRT is that reading comprehension…

The authors of the "Childhood Autism Rating Scale" (CARS) state in the manual that the best cutoff score for distinguishing low functioning autism (LFA) from intellectual disability is 30 for children and 28 for adolescents and adults. This study determined that a cutoff score of 25.5 was most accurate in differentiating between high functioning…

Recently, Gotham et al. ("2007") proposed revised algorithms for the Autism Diagnostic Observation Schedule (ADOS) with improved diagnostic validity. The aim of the current study was to replicate predictive validity, factor structure, and correlations with age and verbal and nonverbal IQ of the ADOS revised algorithms for Modules 1 and 2…

Wieland, J.; Wardenaar, K. J.; Fontein, E.; Zitman, F. G. – Journal of Intellectual Disability Research, 2012
Background: Diagnostics and care for people with intellectual disabilities (ID) and psychiatric disorders need to be improved. This can be done by using assessment instruments to routinely measure the nature and severity of psychiatric symptoms. Up until now, in the Netherlands, assessment measures are seldom used in the psychiatric care for this…
