The statistical population includes all 3 to 22 year-old people suffering from autism disorder among which 113 individuals were chosen as sample group, using systematic sampling. The data collected were analyzed by questionnaires of GARS-3 and 2, and also by using spss 23 software and statistical tests like internal correlation coefficient and Cronbach's alpha.
Results: Results indicated that based on kappa coefficient GARS-3 has got needed translation accuracy. The scale time validity of more than 0/86 coefficient was significantly confirmed 0.01. The validity among correctors that was gained with internal reliability of more than 0/82 was significant in all subscales than those of social relation (p<0/01). It should also be noted that simultaneous validity of this scale with that of GARS-2 indicated the existence of this validity with regard to significant correlation coefficients (p<0/01).
Conclusion: With regard to achieved results, it can be said that GARS-3 enjoys desirable psychometric characteristics to be used in Iranian community, therefore, it is recommended to scientific centers of research as a reliable and valuable tool.
