 Autism Spectrum Disorder, ASD, has become increasingly prevalent worldwide, with Russia being no exception. As a result, there is a need for reliable diagnostic tools to help identify individuals with ASD. Two recently developed diagnostic instruments, the Autism Diagnostic Observation Schedule, ADOS-2, and the Autism Diagnostic Interview, ADAR, have now been translated into Russian. This paper provides an overview of these instruments, discusses their potential applications, and assesses their accuracy in identifying individuals with ASD. The ADOS-2 appears to be a valid and reliable tool for use in Russia, while the ADAR may require further refinement before it can be considered accurate enough for clinical use.
