diagnostic accuracy of the children's communication checklist-persian in identifying children with autism spectrum disorder

Background: this study examined the diagnostic accuracy of the children's communication checklist-persian version (ccc-persian) in differentiating children with autism spectrum disorders (asd) from typically developing (td) children. methods: the parents of 47 children with asd and the parents of 104 td children completed the ccc-persian. the children were monolingual persian-speakers between 5 and 11 years of age. the sensitivity, specificity, likelihood ratios, and cut-off score of the ccc-persian were calculated in identifying children with asd. results: the mean pragmatic composite score (pcs) of the ccc-persian was significantly lower in children with asd than in the td children (p>0.05). corresponding cut-off score, sensitivity, and specificity were 107, 86%, and 97%, respectively. the positive and negative likelihood ratios were obtained as about 30 and 0.14, respectively. conclusion: the ccc-persian has the potential to be used as a valid clinical tool for diagnosing pragmatic language impairment or screening asd in persian-speaking children.
