• Hi! Welcome to the Broad Autism Phenotype Questionnaire, taken from an article in the Journal of Autism and Developmental Disorders (see http://tinyurl.com/3derhn). Ever since Leo Kanner first described autism, it's been observed that many autistics have relatives with autistic traits. Originally this was explained by the 'refridgerator mother' theory, but more recently it's been attributed instead to genetics. This questionnairre is designed to measure the mild autistic traits present in people who are not actually autistic but have a genetic predisposition to autism.
