Understanding Autistic Traits

The Revised Comprehensive Autistic Trait Inventory (CATI-R) is a self-report measure originally developed by Michael C. W. English, Gilles E. Gignac, Troy A. W. Visser, Andrew J. O. Whitehouse, James T. Enns, and Murray T. Maybery at the University of Western Australia and the University of British Columbia. The CATI-R was revised in partnership with 22 individuals from the autism and autistic communities to increase clarity, reduce stigma, and better capture diverse autistic experiences. It assesses traits across six dimensions: Social Interactions, Communication, Social Camouflage, Self-Regulatory Behaviours, Cognitive (In)Flexibility, and Sensory Sensitivity.

Note: This survey is not a diagnostic tool. It is part of a research study exploring the relationship between autistic traits and imagery experiences, including aphantasia.

Instructions: Below is a list of statements relating to various personality traits, behaviours, and characteristics. Using the five response options, select the option that best describes you. When responding, think about yourself both now and across your life. 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.
