Self Screen

Self-screening tests for autism and ADHD are quick and convenient tools for exploring whether you have traits or are experiencing symptoms that are commonly experienced by autistic people and/or individuals with ADHD. The results from self-screening tests don’t provide enough information for a formal diagnosis, but they can be a great tool for helping you decide if you want to seek a comprehensive evaluation.

Our self-screening tool was designed for adults ages 18 and up. It is composed of two different questionnaires that screen for autistic traits, the Comprehensive Autistic Trait Inventory (CATI) and the Camouflaging Autistic Traits Questionnaire (CAT-Q), and one questionnaire that screens for traits and symptoms of ADHD, the Adult ADHD Self-Report Screening Scale (ASRS). The CATI, CAT-Q, and ASRS are scientifically developed instruments created by independent teams of researchers who study neurodivergence. 

One major limitation to keep in mind when taking the self-screen is that these measures aren’t 100% accurate. No online test for autism or ADHD is. All psychometric tests have varying rates of false negatives and false positives. This means that having scores that are more similar to autistic adults on one or more measures does not necessarily mean that you are autistic. Similarly, even if all your scores fall in the neurotypical range, that doesn’t necessarily mean you aren’t neurodivergent.

When you’re through with the self-screen, you’ll be given your scores so that you can see how your responses compare to those of neurotypical and neurodivergent adults. The self-screen can’t tell you whether you’re autistic or if you have ADHD, but it can be a helpful tool for self-reflection and deciding whether a comprehensive evaluation might be right for you.

Take the Self Screen

Please be aware that this screening measure is for informational purposes only and does not constitute a professional diagnostic assessment or the establishment of a psychologist-client relationship. This self-assessment is a preliminary tool designed to help you understand whether traits you might have, or symptoms you might be experiencing, may be consistent with autism or ADHD. However, it is not a substitute for a professional evaluation. For a comprehensive assessment and personalized guidance, we strongly recommend an evaluation with Dr. Duncan or another qualified mental health professional who specializes in working with neurodivergent adults.

The Comprehensive Autistic Trait Inventory (CATI) was developed by Michael English, Gilles Gignac, Troy Visser, Andrew Whitehouse & Murray Maybery.

The Camouflaging Autistic Traits Questionnaire (CAT-Q) was developed by Laura Hull, William Mandy, Meng-Chuan Lai, Simon Baron-Cohen, Carrie Allison, Paula Smith & K. V. Petrides.

Both the CATI and the CAT-Q are available for use under Creative Commons Attribution 4.0 International Licenses, which permit use, sharing, adaptation, distribution and reproduction in any medium or format.

The adult ADHD Self-Report Screening Scale (ASRS) was developed as a joint effort between the World Health Organization, New York University, and Harvard College.
