Principal Component Analysis of the PEAK Generalization Module

AbstractThe current study sought to assess the content validity and internal consistency of the PEAK Generalization Module. Eighty-four children with autism were evaluated using the PEAK Generalization Assessment to ascertain the presence or absence of 184 language and learning skills within the child ’s repertoire. Following the assessment, a principal component analysis was run yielding a four-component model of the PEAK Generalization Module. Specifically, components possessing eigenvalues greater than 3 and that had at least one item which was most strongly correlated to them were retained. Items were then sorted into the various components based on their correlation scores within the rotated component matrix generated by the principal component analysis. Following the establishment of the four-component model, the internal consistency of the model was tested using Cronbach’s Alphas which indicated strong internal consistency in the overall PEAK-G Assessment as well as each of the four underlying components. The four components identified include the constructs of Foundational Learning and Basic Social Skills, Basic Verbal Comprehension, Memory, and Advanced Social Skills, Adv anced Verbal Comprehension, Reading and Writing, and Basic Problem Solving Skills, and Verbal Reasoning, Problem Solving, Logic, and Mathematical Skills. With the increased demand for evidence-based intervention as the number of individuals with diagnoses of autism rises, the present dat...

Publication date: Available online 12 December 2019Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Naomi Tistarelli, Corrado Fagnani, Miriam Troianiello, Maria Antonietta Stazi, Walter AdrianiAbstractAttention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children worldwide, and also the recognition of its persistence into adulthood is increasing. While ADHD in childhood is highly heritable and mostly driven by familial factors, during adulthood it appears to show a lower heritability, even if there is not total agreement on this yet. This disorder often co-occurs with many othe...

ConclusionsStudies have focused predominantly on assessing transcription or translation/text generation skills with little systematic attention to relationships between writing and language domain or mediational systems skills. Reviewed studies offer preliminary findings, areas of needed future research, and implications for continued research into understanding and supporting the writing skill development of children with ASD.

Authors: Kurihara M, Ishiura H, Bannai T, Mitsui J, Yoshimura J, Morishita S, Hayashi T, Shimizu J, Toda T, Tsuji S Abstract Heterozygous mutations in KIF1A have been reported to cause syndromic intellectual disability or pure spastic paraplegia. However, their genotype-phenotype correlations have not been fully elucidated. We herein report a man with autism and hyperactivity along with sensory disturbance and spastic paraplegia, carrying a novel de novo mutation in KIF1A (c.37C>T [p.R13C]). Autism and hyperactivity have only previously been reported in a patient with c.38 G>A (R13H) mutation. This case sugge...

This study examines the efficacy of the Japanese version of the Program for the Education and Enrichment of Relational Skills (PEERS), which focuses on improving social functioning through making friends and maintaining good relationships for adolescents with autism spectrum disorder (ASD) without intellectual disabilities. Originally developed in the United States, PEERS is one of the few evidence-based social skills training programs for youth with ASD. The present study shows that with linguistic and cultural modifications, PEERS is effective in improving social functioning for adolescents with ASD in Japan. Positive re...

AbstractMicrodeletions encompassing 14q11.2locus, involvingSUPT16H andCHD8, were shown to cause developmental delay, intellectual disability, autism spectrum disorders and macrocephaly. Variations leading toCHD8 haploinsufficiency or loss of function were also shown to lead to a similar phenotype. Recently, a 14q11.2 microduplication syndrome, encompassingCHD8 andSUPT16H, has been described, highlighting the importance of a tight control of at leastCHD8 gene-dosage for a normal development. There have been only a few reports of 14q11.2 microduplications. Patients showed variable neurodevelopmental issues of variable severi...

Conclusion: The researchers that examined school aged children, all agreed that children with disabilities would benefit from the use of assistive technology. However, they also agree that teachers are not prepared to incorporate advanced technology in the classroom. The results also show that children with physical disabilities in preschool may be too young to independently use advanced technology.Implications for RehabilitationStudents with severe disabilities often have limited interactions with same age peers. Technology can provide a means to increase the quality and quantity of time interacting with young student's p...
