Complete the CATI online
Instructions
You will be presented with 42 statements relating to various personality traits, behaviours, and characteristics. Using the five response options select the option that best describes you. For items of a social nature, think about situations that do not involve very close friends or family members. Try not to spend too much time thinking about each choice.
Clicking or tapping a response option will make the next statement automatically appear.
When you have responded to all 42 statements, your scores will be calculated and presented to you.
Your responses will be calculated within the browser and will not be transferred to another computer or server. Please print the final page or take a screenshot of your results if you wish to refer to them later.

Your Total CATI score is summarised below, followed by your subscale scores. To provide context, we compare your scores with data from our 2025 study, which included 1,279 non-autistic people and 1,322 autistic people (50-50 self-identifying and diagnosed).
The CATI is intended to provide a descriptive summary of traits and characteristics qualitatively similar to those found in clinical autism. It is NOT intended to be diagnostic or replace a diagnosis received by qualified clinicians using clinically-validated tools. CATI scores may be influenced by other factors that overlap with autism. If you have any concerns about your scores, please discuss them with your GP.
