Autism Spectrum Screening Questionnaire | ASSQ

Autism Spectrum Screening Questionnaire (ASSQ) was originally developed by Ehlers, Gillberg, and
Wing (1999) as a 27-item checklist specifically designed to identify characteristics of high-functioning
autism spectrum disorders (ASD), including Asperger syndrome, in school-aged children with normal or
borderline intellectual ability. Since its original publication, the ASSQ has been translated and validated
across multiple languages and cultural contexts, establishing a robust evidence base that supports its use
as a brief, reliable informant-rated screening tool
