Assessing anxiety in Iranian children with Autism Spectrum Disorder

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.

Processing Differences

Purpose The aim of this research study was to examine common practices of speech-language pathologists (SLPs) who work with children with autism spectrum disorder (ASD) with respect to whether or not SLPs consider processing differences in ASD or the effects of input during their instruction. Method Following a qualitative research method, how SLPs instruct and present augmentative and alternative communication systems to individuals with ASD, their rationale for method selection, and their perception of the efficacy of selected interventions were probed. Semistructured interviews were conducted as part of an in-depth case report with content analysis. Results Based on completed interviews, 4 primary themes were identified: (a) instructional method , (b) input provided , (c) decision-making process , and (d) perceived efficacy of treatment . Additionally, one secondary theme, training and education received , was identified . Conclusions Clinicians reported making decisions based on the needs of the child; however, they also reported making decisions based on the diagnostic category that characterized the child (i.e., ASD). The use of modeling when teaching augmentative and alternative communication to individuals with ASD emerged as a theme, but variations in the method of modeling were noted. SLPs did not report regularly considering processing differences in ASD, nor did they consider the effects of input during instruction.
