Purpose The purpose of this paper is to assess the validity of the Autism Diagnostic Interview-Revised (ADI-R) in an Iranian population to determine its efficacy in identifying children with autism spectrum disorder (ASD) who parents have Persian-speaking parents. Design/methodology/approach A case–control study was performed in March until July 2020 in Hamadan city, Iran. The case group was children were examined by the clinicians used a coding scheme based on the DSM-IV criteria for ASD. The control group was all children in the family, including healthy siblings, were asked to participate in the study. The reliability, content and face validity were performed to assess the psychometric properties of the tool. Confirmatory factor analysis (CFA) was performed to evaluate the four-dimensional structure of the tool (Scores A, B, C and D). Statistical analysis was performed using AMOS for SPSS 21, and the statistical significant level was less than 0.05. Findings The quantitative content validity analysis revealed that the mean of content validity ratio (CVR) and content validity index (CVI) for all domains was 0.94 and 0.91, respectively. For CFA, four domains A, B, C and D were used and demonstrated a good fit (CFI = 0.92 and RMSEA = 0.06). The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) in domains A, B (verbal), C and D were 100%. For domain B (non-verbal), the sensitivity, specificity, PPV and NPV were 86.7%, 100%, 100% and 88.2%, respectively. Research limitations/implications This study showed that ADI-R has sufficient ability to discriminate between children with ASD and those with no psychiatric diagnosis, and it is a reliable tool in Iran. The sensitivity and specificity for correctly diagnosing ASD was high, regardless of the age and cognitive level of the examiner. Originality/value To the best of the authors’ knowledge, this is the first paper on psychometric properties of ADI-R in children with ASD.

AbstractDue to the importance of automatic and early autism screening, in this paper, a cry-based screening approach for children with Autism Spectrum Disorder (ASD) is introduced. During the study, we realized that the ASD specific features are not necessarily observable among all children with ASD and among all instances of each child. Therefore, we proposed a new classification approach to be able to find such features and their corresponding instances. We tested the proposed approach and found two features that can be used to distinguish groups of children with ASD from Typically Developing (TD) children. In other words, these features are present in subsets of children with ASD not all of them. The approach has been tested on a dataset including 14 boys and 7 girls with ASD and 14 TD boys and 7 TD girls, between 18 to 53 months old. The sensitivity, specificity, and precision of the proposed approach for boys were 85.71%, 100%, and 92.85%, respectively. These measures were 71.42%, 100%, and 85.71% for girls, respectively.

PurposeThe purpose of this paper is to investigate whether age plays a role in the acquisition of construct state (CS) constructions in Arabic by 14 children with autism spectrum disorder (ASD). It also examined the challenges faced by children with ASD in producing different types of CS constructions. Finally, the study analysed the sources of difficulties children with ASD encounter during the learning process of the CS.Design/methodology/approachFor the purposes of this study, the participants were asked to orally complete short sentences with the help of illustrative pictures.FindingsResults revealed that the age of the 14 children with ASD plays a role in the acquisition of CS constructions. Children of age 12–15 performed better than those of age 8 and 10. Results also showed that children with ASD performed better in producing phrases rather than compounds. Moreover, the participants performed better on endocentric compounds as opposed to exocentric ones. Finally, analysing the errors produced on the text revealed that the acquisition of head direction precedes definiteness.Originality/valueThe topic of the study has not been investigated yet and the study concluded with some important findings concerning teaching Arabic CS to children with ADS.

Purpose The purpose of this paper is to investigate why children with autism spectrum disorder (ASD) tend to respond to tasks from their own perspective. The authors investigated the effects of explicitness of viewpoint on performance of spontaneous level 2 perspective-taking skills in six- to eight-year-old children with ASD. Design/methodology/approach The authors conducted visual perspective-taking tasks with explicit and implicit instructions about the viewpoint to be used. Participants operated a toy car on a map while listening to the experimenter’s instructions. In the implicit condition, when the experimenter said “Turn right/left” at each intersection, the participants moved the car accordingly. Subsequently, in the explicit condition, the experimenter said “Look from the driver’s viewpoint and turn right/left” at each intersection. Findings In the implicit condition, the authors did not observe a clear developmental change in performance between six- and eight-year-old children in the ASD group. In contrast, performance in the ASD group improved under the explicit condition relative to that under the implicit condition. Originality/value The results suggest six- to eight-year-old children with ASD tend not to spontaneously use level 2 perspective-taking skills. Therefore, viewpoints should be explicitly instructed to children with ASD. In addition, it is also important to implement training to encourage spontaneous transitions from self-perspective to other-perspective under the implicit condition.

Abstract Date Presented Accepted for AOTA INSPIRE 2021 but unable to be presented due to online event limitations. Participation of children with autism spectrum disorder (ASD) is limited compared with their typically developing (TD) peers. This study examined the participation of children with ASD using an adapted observation in comparison with TD children. Content validity was evaluated by 21 experts, and 70 children were observed. Children with ASD scored significantly lower than TD children in most areas. More structured settings enabled higher participation scores. Further studies are needed.

A Delphi consensus methodology was used to adapt the Autism Diagnostic Interview–Revised for the assessment of deaf children with suspected autism spectrum disorder. Each Autism Diagnostic Interview–Revised item was considered by a panel of nine international experts in terms of relevance and acceptability. Modifications were proposed and agreed by the expert panel for 45% of items. The pre-specified criterion for agreement between experts was set at 80% for each item. A first validation of the revised version, adapted for deaf children (Autism Diagnostic Interview–Revised Deaf Adaptation), was undertaken with a UK sample of 78 parents/carers of deaf children with autism spectrum disorder and 126 parents/carers with deaf children without autism spectrum disorder. When compared to National Institute for Health and Care Excellence guideline standard clinical assessments, the Autism Diagnostic Interview–Revised Deaf Adaptation diagnostic algorithm cut-off/threshold scores achieved a sensitivity of 89% (79%–96%) and specificity of 81% (70%–89%) for autism spectrum disorder. The alpha coefficients for each algorithm symptom domain ranged from 0.80 to 0.91, suggesting that the items had high internal consistency. Our findings indicate that the Autism Diagnostic Interview–Revised Deaf Adaptation is likely to be a useful measure for the assessment of deaf children with suspected autism spectrum disorder, although further research is needed. Lay abstract Autism assessment processes need to improve for deaf children as they are currently being diagnosed later than their hearing counterparts and misdiagnosis can occur. We took one of the most commonly used parent developmental interviews for autism spectrum disorder the Autism Diagnostic Interview–Revised and adapted it using international expert advice. Modifications were proposed and agreed by the expert panel for 45% of items; the remaining 55% of items were unchanged. We then tested the revised version, adapted for deaf children (Autism Diagnostic Interview–Revised Deaf Adaptation), in a UK sample of 78 parents/carers of deaf children with autism spectrum disorder and 126 parents/carers with deaf children without autism spectrum disorder. When compared to National Institute for Health and Care Excellence guideline standard clinical assessments, the Autism Diagnostic Interview–Revised Deaf Adaptation diagnostic algorithm threshold scores could identify those deaf children with a definite diagnosis (true autism spectrum disorder positives) well (sensitivity of 89% (79%–96%)) and those deaf children who did not have autism spectrum disorder (true autism spectrum disorder negatives) well (specificity of 81% (70%–89%)). Our findings indicate that the Autism Diagnostic Interview–Revised Deaf Adaptation is likely to prove a useful measure for the assessment of deaf children with suspected autism spectrum disorder and that further research would be helpful.

The assessment instruments for diagnosing children with autism spectrum disorder have been developed mostly in affluent, English-speaking countries. Among the most popular has been the Autism Diagnostic Interview–Revised. This article reports its use in Iran with the dual aims of confirming the factor structure of the revised Autism Diagnostic Interview when used to assess Iranian children for autism spectrum disorder and to identify the algorithms that best distinguish children with autism spectrum disorder from those who are developing typically and from those with intellectual disability. Study 1 contrasted the Autism Diagnostic Interview–Revised ratings given to 420 children with autism spectrum disorder from those of 110 typically developing children. In Study 2, the Autism Diagnostic Interview–Revised ratings of 720 children with autism spectrum disorder were compared with those of 172 children with intellectual disability, and from those with intellectual disability. Exploratory factor analyses identified one main factor that merged the social interaction and communication items of Autism Diagnostic Interview–Revised, but replicated the repetitive behaviour and verbal factors. Receiver operating characteristic analyses identified suitable cut-off points on the revised factor scores. Also, the age at which symptoms became apparent increased the sensitivity of the algorithm in distinguishing children with autism spectrum disorder from those with intellectual disability. These findings are in line with the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), recommendations and suggest a commonality in autism spectrum disorder presentations across different nations. The methodology used in this research could guide similar adaptations of assessment instruments for use in other cultures. Lay abstract The diagnosis of autism spectrum disorder is a challenging task. Most of the current assessment scales have been developed in the West. The present study examines the applicability of one of the most used scales (the Autism Diagnostic Interview–Revised) in a Middle-Eastern culture. Two studies were undertaken. In the first, the Autism Diagnostic Interview–Revised ratings given to 420 children with autism spectrum disorder, aged 4–11 years, and 110 typically developing children were contrasted. In Study 2, the Autism Diagnostic Interview–Revised ratings of 720 children with autism spectrum disorder were compared with those of 172 children with intellectual disabilities to find out whether the Autism Diagnostic Interview–Revised scale would discriminate between these two types of developmental disabilities. The studies confirmed the acceptability of the scale to Iranian parents and assessors. However, the summary scores used to determine whether a child was likely to have autism spectrum disorder were recalculated on the two domains of social communication and repetitive behaviours, which were identified in the statistical analyses that are recommended for the evaluation of assessment scales. Thus the translated scale with the modified domain scoring proved very suitable for identifying Iranian children with autism spectrum disorder. Having a common tool such as Autism Diagnostic Interview–Revised will strengthen the opportunities to undertake cross-cultural research into the impact of autism spectrum disorder on the child and families.

<p class="apa">The present study sought to examine parents’ perceptions of early interventions and related services for children with autism spectrum disorder (ASD) in Saudi Arabia. In this study a survey was distributed to a sample of 80 parents with children who have ASD. Parents also were asked open-ended questions to enable them to provide suggestions. The findings indicate that parents have varying perceptions of early interventions and related services. However, they seem to agree that these services are important in assisting their children. Accordingly, parents have suggested that the government needs to increase these services by providing more centers for children with ASD in Saudi Arabia, providing more specialists to deal with children with ASD, promoting inclusion in regular schools and providing more information on early intervention.</p>

(1) Background: Children with Autism Spectrum Disorder (ASD) frequently have difficulties in processing sensory information, which is a limitation when participating in different contexts, such as school. The objective of the present study was to compare the sensory processing characteristics of children with ASD in the natural context of school through the perception of professionals in the field of education, in comparison with neurodevelopmental children (2) Methods: A cross-sectional descriptive study as conducted with study population consisting of children between three and ten years old, 36 of whom were diagnosed with ASD and attended the Autismo Burgos association; the remaining 24 had neurotypical development. The degree of response of the children to sensory stimuli at school was evaluated using the Sensory Profile-2 (SP-2) questionnaire in its school version, answered by the teachers. (3) Results: Statistically significant differences were found in sensory processing patterns (p = 0.001), in sensory systems (p = 0.001) and in school factors (p = 0.001). Children with ASD who obtained worse results. (4) Conclusions: Children with ASD are prone to present sensory alterations in different contexts, giving nonadapted behavioral and learning responses.

AbstractMost children with autism spectrum disorder (ASD), in resource-limited settings (RLS), are diagnosed after the age of four. Our work confirmed and extended results of Pierce that eye tracking could discriminate between typically developing (TD) children and those with ASD. We demonstrated the initial 15 s was at least as discriminating as the entire video. We evaluated the GP-MCHAT-R, which combines the first 15 s of manually-coded gaze preference (GP) video with M-CHAT-R results on 73 TD children and 28 children with ASD, 36–99 months of age. The GP-MCHAT-R (AUC = 0.89 (95%CI: 0.82–0.95)), performed significantly better than the MCHAT-R (AUC = 0.78 (95%CI: 0.71–0.85)) and gaze preference (AUC = 0.76 (95%CI: 0.64–0.88)) alone. This tool may enable early screening for ASD in RLS.

The Wechsler Intelligence Scales for Children (WISC) are the most widely used instrument in assessing cognitive ability, especially with children with autism spectrum disorder (ASD). Previous literature on the WISC has demonstrated a divergent pattern of performance on the WISC for children ASD compared to their typically developing peers; however, there is a lack of research concerning the most recent iteration, the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V). Due to the distinctive changes made to the WISC-V, we sought to identify the pattern of performance of children with ASD on the WISC-V using a classification and regression (CART) analysis. The current study used the standardization sample data of the WISC-V obtained from NCS Pearson, Inc. Sixty-two children diagnosed with ASD, along with their demographically matched controls, comprised the sample. Results revealed the Comprehension and Letter-Number Sequencing subtests were the most important factors in predicting group membership for children with ASD with an accompanying language impairment. Children with ASD without an accompanying language impairment, however, were difficult to distinguish from matched controls through the CART analysis. Results suggest school psychologists and other clinicians should administer all primary and supplemental subtests of the WISC-V as part of a comprehensive assessment of ASD.
