Autism Spectrum Screening Questionnaire (Teacher-Rated)

What is ASSQ (Teacher-Rated)

The high-functioning Autism Spectrum Screening Questionnaire (ASSQ) is a 27-item check-list for completion by lay informants when assessing symptoms characteristic of Asperger syndrome and other high-functioning autism spectrum disorders in children and adolescents with normal intelligence or mild mental retardation. ASSQ is a useful brief screening device for the identification of autism spectrum disorders in clinical settings.

Since the questionnaire relies on client's observations, all responses should be verified by the clinician, and a definitive diagnosis is made on clinical grounds taking into account how well the client understood the questionnaire, as well as other relevant information from the client.

The questionnaire was designed for completion by lay informants. It needs no prior training before completion, and takes about 10 minutes to fill in. The ASSQ was designed as a screening instrument due to the fact that lay informants' ratings on scales, such as this, are highly subjective and biased judgments. Thus, the ASSQ is not intended for diagnostic purposes, but as a measure for identifying children who need a more comprehensive evaluation.

The original findings by authors do not indicate that the ASSQ distinguishes between Asperger syndrome and other high-functioning autistic disorders.
