This study aimed to assess the validity and normative statistics of the Farsi version of the Social Responsiveness Scale-2 (SRS-2). Among the mainstream elementary schools, 191 boys and 342 girls with a mean age of 9.46 (+ 1.72) years were recruited. Teachers and parents completed the SRS-2. The parents also answered the Social Communication Questionnaire (SCQ) and the Vineland Adaptive Behavior Scale (VABS). There were not any significant differences regarding the parents' and teachers' ratings of the SRS mean scores in terms of gender, academic level, and age. The SRS was significantly correlated with the SCQ (0.438) and VABS (- 0.142) mean scores. The study supported the validity of the SRS as a screening instrument for social communication problems in Farsi-speaking school-aged children.
