Adaptation of the Questionnaire BISCUIT for the Early Detection of Autism Spectrum Disorders

The article presents the adaptation results for “Baby and Infant Screen for Children with aUtIsm Traits (BISCUIT)” questionnaire for early diagnosis of autism spectrum disorders (ASD) in the Russian-speaking sample (n=105). We evaluated the psychometric properties of the Russian version questionnaire: internal consistency reliability, construct validity, criterion-related validity and item discrimination. According to the results of the adaptation, BISCUIT questionnaire has good psychometric indicators, however, cutoff scores should be revised on a standardization sample with a larger number of clinical cases.
