Polish adaptation of the social communication questionnaire (Scq) and female autism phenotype: An investigation of potentially sex-biased items in the screening assessment and their impact on scores

Abstract

Standardized screening assessments and sex differences in autism spectrum disorder (ASD) are still under-explored in Poland. This study investigated the differences between Polish ASD females and males based on the responses provided by parents/caregivers to a Polish adaptation of the Social Communication Questionnaire, SCQ Lifetime and SCQ Current. The study included 90 ASD participants from Mental Health Services and Autism Clinics in Poland with no intellectual disability and no profound communication difficulties. Parents provided information on the SCQ items which were compared under three domains of the Autism Diagnostic Interview-Revised (ADI-R). Four SCQ items with the examples were investigated. No significant differences were found between the two sexes in the three domains. The repetitive use of objects declined with age in ASD males. Although the findings of the present study did not reveal substantial gender biases in the Polish adaptation of the SCQ, it is necessary to take into account potential gender differences in the clinical presentation of ASD and in the adaptation of screening and diagnostic tools.
