AuDHD Profile Test (CATI/ASRS)

The AuDHD Profile Test brings together two established psychological questionnaires: the Comprehensive Autistic Trait Inventory (CATI), published by Michael C. W. English, Murray T. Maybery, and colleagues at the University of Western Australia in Molecular Autism (2021), and the Adult ADHD Self-Report Scale (ASRS), developed by Ronald C. Kessler, Lenard Adler, and colleagues with the World Health Organization (2005). In the neurodivergent community, AuDHD is widely used to describe the co-occurrence of autistic and ADHD traits. Although clinical manuals like the DSM only permitted diagnosing both conditions together starting in 2013, psychological research now demonstrates that autism and ADHD frequently overlap, with studies estimating that over half of autistic individuals also exhibit significant ADHD traits.

To give you a comprehensive picture, the test measures eight distinct areas without blurring them together. Across the autistic dimension, it explores Social Difficulty (stress in social situations), Communication Difficulty (interpreting non-verbal cues and figures of speech), Social Camouflage (the cognitive effort of masking to fit in), Repetitive Behaviors (stimming actions like rocking or fidgeting), Cognitive Rigidity (relying on predictability and established routines), and Sensory Sensitivity (heightened reactivity to sound, light, or touch). Across the ADHD dimension, it examines Inattention (trouble organizing, finishing details, or sustaining focus) alongside Hyperactivity Impulsivity (physical restlessness, difficulty unwinding, and spontaneous speech).

Experiencing both sets of traits often creates a distinct internal dynamic. While ADHD craves novelty, stimulation, and spontaneous change, autistic neurology frequently needs predictability, stability, and quiet recovery time. These traits can also mask one another: executive dysfunction may be managed through rigid autistic routines, while intense social masking can conceal underlying inattention. At the same time, this profile often carries notable strengths, including creative problem-solving, rapid associative thinking, high energy, deep focus on passionate interests, and an exceptional eye for detail.

Your result opens with one overall AuDHD score, the average of Total Autistic Traits and Total ADHD Traits, and then presents both totals separately, alongside all eight specific subscales. This side-by-side view allows you to see how your neurodivergent traits interact beyond the single summary score. Scoring high across both dimensions suggests a pronounced AuDHD pattern, whereas an elevated score on only one dimension indicates that a single profile dominates. If both scores fall near typical ranges, neither trait cluster stands out prominently.

To help you interpret your profile, your result compares your stronger side with the average person. That average is an informed reference estimate derived from average scores reported across published research samples rather than clinically standardized norms or individual percentiles. It serves as a general backdrop for understanding relative trait intensity rather than a definitive cutoff or rigid boundary.

This test is intended strictly for educational, informational, and personal reflection purposes. It is not a diagnostic tool, does not provide medical or psychological advice, and cannot substitute for a formal clinical evaluation. This assessment is based on the Comprehensive Autistic Trait Inventory (CATI) and Adult ADHD Self-Report Scale (ASRS) but is not affiliated with the original authors, their research institutions, or the World Health Organization. If your traits cause ongoing stress or impairment in daily life, consider speaking with a licensed neurodiversity-affirming clinician who specializes in assessing both autism and ADHD.
