The present study has been performed with the aim of designing and evaluating the psychometric properties of Autism Spectrum Disorders Diagnosis Scale (ASDDS).
This study is an instrumental and validity evaluation. The statistical community of the research consisted of all children with autism spectrum who live in Isfahan. Among them, 100 patients were selected by method of convenient sampling, and also their mothers or trainers were asked for responding the scales of study. The tools of data gathering included demographic information and a researcher-made scale named Autism Spectrum Disorder Diagnosis Scale (ASDDS) according to reversion of DSM-5. Also, Giliam Autism Rating Scale (GARS) and Children Autism Rating Scale (CARS) were used for evaluating the concurrent validity.
The results of the psychometrics of the scale indicated appropriate content, convergent and diagnostic validity, and internal consistency as well as the scale stability over the time. The correlation coefficient between sub-scales showed very high correlation between the sub-scales. The results obtained from the confirmatory factorial analysis indicated that the DSM-5 model is appropriate for scale. In addition, the general reliability of the scale by using of Cronbach's alpha was 0.88.
the results demonstrated that Autism Spectrum Disorder Diagnosis Scale (ASDDS) is a suitable tool for diagnosing autism spectrum disorders based on DSM-5 in children and adolescents.

The present meta-analysis was aimed to evaluate the effectiveness of applied behavior analysis (ABA) on behavioral problems and difficulties in children with autism spectrum disorders in Iran. A total of 142 studies published from 2005 to 2013 were reviewed and eight studies were selected for meta-analysis based on applying appropriate methodologies. The eight studies involved a total of 200 participants and since each study focused on multiple autism-related problems, 28 effect sizes were obtained. The research instrument was a checklist of content analysis. The overall mean effect size was found to be r=0.83 (p<0.001). The highest effect size (r=0.926) was obtained in the research of Khorramabadi, et al. (for the variable of cognitive skills) and the lowest effect size (r=0.151) was seen in the study of Mashhadi, et al. (for the variable of social development). The results indicate a large effect size of ABA on decreasing the problems and difficulties of children with autism spectrum disorders in Iran. In addition, greater effects are found when this method is used in long-term and with higher intensity. Therefore, it seems that ABA can be used as an appropriate treatment method for children with autism spectrum disorders.
