Choose the screening that fits your question
These tools cover different questions and levels of detail. They are self-report screeners, not diagnostic examinations.
AQ-10
A brief first check when you want a quick starting point.
Its short format provides less detail than longer questionnaires.
AQ-50
A broader look at autism-related traits across several areas.
It takes longer and still cannot determine whether you are autistic.
RAADS-R
A detailed self-report of current and lifelong experiences.
It was designed to support clinical assessment, not to diagnose on its own.
CAT-Q
Exploring social camouflaging or masking strategies.
It focuses on camouflaging and does not measure every feature associated with autism.
