Autistic Traits (AUTQ)
The Autistic Traits questionnaire is an additional assessment among adult Lifelines participants.
The digital questionnaire was developed at the initiative of the Autism Research Center of Cambridge University (UK), in collaboration with the Sarr (Parnassia group) in Rotterdam (NL).
The questionnaire consists of the 10-item adult version of the Autism Spectrum Quotient, plus some additional questions about participants' experience with informal care in general, and informal care of autism spectrum disorder (ASD) patients in particular.
Protocol & response
The digital questionnaire was sent out between july and november 2019.
~110,000 adult Lifelines participants received the questionnaire, of which ~39,000 participants (35%) responded.
