longitudinal epidemiological study of autism subgroups using autism treatment Evaluation Checklist atec score
Journal of Autism and Developmental Disorders, 2020Co-Authors: Shreyas Mahapatra, Edward Khokhlovich, Samantha Martinez, Benjamin Kannel, Stephen M Edelson, Andrey VyshedskiyAbstract:Here we report the results of the subgroup analyses of an observational cohort of children whose parents completed the Autism Treatment Evaluation Checklist (ATEC) over the period of several years. A linear mixed effects model was used to evaluate longitudinal changes in ATEC scores within different patient subgroups. All groups decreased their mean ATEC score over time indicating improvement of symptoms, however there were significant differences between the groups. Younger children improved more than the older children. Children with milder ASD improved more than children with more severe ASD in the Communication subscale. There was no difference in improvement between females vs. males. One surprising finding was that children from developed English-speaking countries improved less than children from non-English-speaking countries.

development of the mental synthesis Evaluation Checklist msec a parent report tool for mental synthesis ability assessment in children with language delay
2018Co-Authors: Julia Braverman, Rita Dunn, Andrey VyshedskiyAbstract:Mental synthesis is the conscious purposeful process of synthesizing novel mental images from objects stored in memory. Mental synthesis ability is essential for understanding complex syntax, spatial prepositions, and verb tenses. In typical children, the timeline of mental synthesis acquisition is highly correlated with an increasing vocabulary. Children with Autism Spectrum Disorder (ASD), on the other hand, may learn hundreds of words but never acquire mental synthesis. In these individuals, tests assessing vocabulary comprehension may fail to demonstrate the profound deficit in mental synthesis. We developed a parent-reported Mental Synthesis Evaluation Checklist (MSEC) designed to assess mental synthesis acquisition in ASD children. The psychometric quality of MSEC was tested with 3715 parents of ASD children. Internal reliability of the 20-item MSEC was good (Cronbach’s alpha >0.9). MSEC exhibited adequate test–retest reliability; good construct validity, supported by a positive correlation with the Autism Treatment Evaluation Checklist (ATEC) Communication subscale; and good known group validity reflected by the difference in MSEC scores for children of different ASD severity levels. The MSEC questionnaire is copyright-free and can be used by researchers as a complimentary subscale for the ATEC Evaluation. We hope that the addition of MSEC will make the combined assessment more sensitive to small steps in a child’s development. As MSEC does not rely on productive language, it may be an especially useful tool for assessing the development of nonverbal and minimally verbal children.

autism treatment Evaluation Checklist atec norms a growth chart for atec score changes as a function of age
Children today, 2018Co-Authors: Shreyas Mahapatra, Samantha Martinez, Benjamin Kannel, Stephen M Edelson, David Vyshedsky, Julia Braverman, Andrey VyshedskiyAbstract:Most early-intervention Autism Spectrum Disorder (ASD) clinical trials are limited by the availability of psychometric technicians who assess each child’s abilities before and after therapeutic intervention. If parents could administer regular psychometric Evaluations of their children, then the cost of clinical trials will be reduced, enabling longer clinical trials with the larger number of participants. The Autism Treatment Evaluation Checklist (ATEC) was designed nearly two decades ago to provide such a tool, but the norms on the longitudinal changes in ATEC in the “treatment as usual” population were lacking. Here we report the norms of the observational cohort who voluntarily completed ATEC Evaluations over the period of four years from 2013 to 2017.

evaluative criteria of an english language textbook Evaluation Checklist
Journal of Language Teaching and Research, 2012Co-Authors: Jayakaran Mukundan, Vahid NimehchisalemAbstract:Checklists are instruments that help teachers or researchers in the area of English Language Teaching (ELT) to evaluate teaching-learning materials like textbooks. Several Checklists are available in the literature, most of which lack validity. The paper discusses the results of a survey that investigated a group of English as a Second Language (ESL) experts' (n=207) views on a Checklist developed by the present researchers. The results showed an equal level of importance for all the items of the Checklist. Additionally, based on the findings of factor analysis, two items were removed from the Checklist. The study offers useful implications for ELT practitioners and researchers. Further research is necessary to field test the Checklist for its validity and reliability.

developing an english language textbook Evaluation Checklist
Contemporary Issues in Education Research, 2011Co-Authors: Jayakaran Mukundan, Reza Hajimohammadi, Vahid NimehchisalemAbstract:The paper describes the considerations that were taken into account in the development of a tentative English language textbook Evaluation Checklist. A brief review of the related literature precedes the crucial issues that should be considered in developing Checklists. In the light of the previous Evaluation Checklists the developers created a list of the evaluative criteria on which the construct of the Checklist could be established. The developers considered matters of validity, reliability and practicality in the process of its design; however, further research is in process to refine the Checklist. Such an instrument could be used by curriculum designers, material developers and evaluators, as well as English language teachers.

developing an english language textbook Evaluation Checklist a focus group study
2011Co-Authors: Jayakaran Mukundan, Vahid Nimehchisalem, Reza HajimohammadiAbstract:English Language Teaching (ELT) textbook Evaluation Checklists are instruments that help teachers select the most appropriate books for their learners. This paper presents a phase of an on-going project proposed out of the need for a valid, reliable and a practical Checklist. The phase includes a focus group study designed to further refine a Checklist previously developed by the present researchers (Mukundan, Hajimohammadi, & Nimehchisalem, 2011). More specifically, the participants in the focus group (n=6) helped the developers improve the items of the Checklist in reference to their clarity and inclusiveness. The study commenced in the form of an unstructured interview in which the participants brainstormed on the evaluative criteria that should be considered in evaluating ELT textbooks. This was followed by a structured interview in which the participants were provided with a copy of the Checklist. They were free to reword, delete or add items that they considered necessary. As a result of this study, 14 items were added to the Checklist while two were reworded. The findings are expected to be useful for English language teachers, ELT material developers and evaluators as well as curriculum developers. Further study is required to improve the instrument.

randomized controlled trial of vitamin d supplementation in children with autism spectrum disorder
Journal of Child Psychology and Psychiatry, 2018Co-Authors: Khaled Saad, Ahmed A Abdelrahman, Yasser M Elserogy, Abdulrahman A Alatram, Amira A Elhoufey, Hisham A K Othman, Geir Bjorklund, Mauricio A Urbina, Mohamed Gamil M AboelelaAbstract:Background Autism spectrum disorder (ASD) is a frequent developmental disorder characterized by pervasive deficits in social interaction, impairment in verbal and nonverbal communication, and stereotyped patterns of interests and activities. It has been previously reported that there is vitamin D deficiency in autistic children; however, there is a lack of randomized controlled trials of vitamin D supplementation in ASD children. Methods This study is a double-blinded, randomized clinical trial (RCT) that was conducted on 109 children with ASD (85 boys and 24 girls; aged 3–10 years). The aim of this study was to assess the effects of vitamin D supplementation on the core symptoms of autism in children. ASD patients were randomized to receive vitamin D3 or placebo for 4 months. The serum levels of 25-hydroxycholecalciferol (25 (OH)D) were measured at the beginning and at the end of the study. The autism severity and social maturity of the children were assessed by the Childhood Autism Rating Scale (CARS), Aberrant Behavior Checklist (ABC), Social Responsiveness Scale (SRS), and the Autism Treatment Evaluation Checklist (ATEC). Trial registration number: UMIN-CTR Study Design: trial number: UMIN000020281. Results Supplementation of vitamin D was well tolerated by the ASD children. The daily doses used in the therapy group was 300 IU vitamin D3/kg/day, not to exceed 5,000 IU/day. The autism symptoms of the children improved significantly, following 4-month vitamin D3 supplementation, but not in the placebo group. This study demonstrates the efficacy and tolerability of high doses of vitamin D3 in children with ASD. Conclusions This study is the first double-blinded RCT proving the efficacy of vitamin D3 in ASD patients. Depending on the parameters measured in the study, oral vitamin D supplementation may safely improve signs and symptoms of ASD and could be recommended for children with ASD. At this stage, this study is a single RCT with a small number of patients, and a great deal of additional wide-scale studies are needed to critically validate the efficacy of vitamin D in ASD.
