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.

A national study of the prevalence of autism among five-year-old children in Iran / Sayyed Ali SAMADI in Autism, 16-1 (January 2012)

The Autism Diagnostic Interview-Revised (ADI-R) is used to confirm a diagnosis of typical autism. The resulting prevalence of 6.26 per 10,000 for typical autism is in line with rates for certain countries but is lower than those reported recently for some Western nations. This may be due to the younger age range assessed but the suitability of the tools and aspects of Iranian culture could be other reasons for the lower prevalence. International comparisons of prevalence rates is fraught with difficulties, but it is a valuable endeavour as it can identify issues around cultural and societal perceptions of children’s development.

The Childhood Autism Rating Scale Second Edition (CARS2) and Its Applicability in an Iranian Sample / Sayyed Ali SAMADI in Autism Research, 18-3 (March 2025)  

Public ISBD [article]  inAutism Research > 18-3 (March 2025) . - p.541-552 Titre : The Childhood Autism Rating Scale Second Edition (CARS2) and Its Applicability in an Iranian Sample Type de document : Texte imprimé et/ou numérique Auteurs : Sayyed Ali SAMADI, Auteur ; Ameneh MAHMOODIZADEH, Auteur ; Mehdi FOLADGAR, Auteur ; Shahnaz Bakhshalizadeh MORADI, Auteur ; Baran LOTFI, Auteur ; Roy MCCONKEY, Auteur Article en page(s) : p.541-552 Langues : Anglais (eng) Mots-clés : autism spectrum  childhood autism rating  cultural adaptations  Iran  Psychometrics  scale second edition (CARS 2)  validation Index. décimale : PER Périodiques Résumé : ABSTRACT The present study aimed to evaluate the reliability and validity of the Childhood Autism Rating Scale: Second Edition (CARS2) in diagnosing individuals with autism in Iran. A mixed-method approach was used and 313 participants were recruited, with an age range of 2?32?years, for CARS2-Standard Form (ST) and 218 individuals aged 6?25?years for CARS2-High Functioning (HF). The participants were recruited from daycare centers, schools, and clinics with different developmental trajectories: autism, intellectual disabilities, and neurotypical development. All participants with autism and intellectual disabilities had been clinically diagnosed previously. In addition, the CARS2-Questionnaire of Parent Concerns (QPC) was used to gather qualitative data on 30 randomly selected parents and the perspectives of the 20 test administrators were also collected. The CARS2 had high internal consistency, inter-rater reliability, and test?retest reliability. Factor analyses revealed a one-factor structure for CARS2-ST and a three-factor structure for CARS2-HF. When adjustments were made to the cut-off points, the discriminant analyses indicated that CARS2 effectively differentiated between those with autism and typical development but less so with persons who had intellectual disabilities. The qualitative data analysis and the extracted themes suggest that the CARS2-QPC is a valid tool for collecting autism-related information from parents. Our findings suggest that the CARS2 is broadly a reliable and valid instrument for diagnosing autism spectrum in Iran in the absence of more extensive assessments.
