How the ASSQ is used
Recommended cut-off scores vary somewhat depending on the country, whether parents or teachers are used as informants and whether the main priority is high sensitivity, specificity or both. In Sweden, 15 points is considered the cut-off score for non-clinical populations and 19 for clinical populations.
An extended version (ASSQ-REV) has also been developed in order to identify girls with autism.
