Using the tools with desirable psychometric features for the considered population is one of the diagnostic ways of the disorder. The goal of the study was to specify sensitivity, specificity, and accuracy of 3rd version of GARS-3 edition (Gilliam autism rating scale- 3) in Persian.
Materials and Methods: This descriptive research is of authentication type. The statistical sample was selected from four provinces in 2019- 2020 and included 3- 22 year-old people; out of which 117 were autistic, 55 deaf, 94 mental retarded, and 52 normal. The data was collected from the sample group and GARS (2013) questionnaire then was analyzed by descriptive indexes.
Results: The results indicated that for both 4 and 6-point scales in accuracy index, the maximum amount for the autistic and normal groups was 0.93, and the minimum amount for the autistic and mental retarded ones was 0.76. In specificity index, the maximum amount for the autistic and normal groups was 0.90, and the minimum amount for the autistic and mental retarded ones was 0.52, and finally for sensitivity index the amount was 0.95.
Conclusion: With regard to the achieved results of 3 significant psychometric scopes, using this type of screening tool to diagnose ASD in Iranian kids is advised. Although using other psychometric findings is also emphasized.
