My CATI-PCP report
Raw scores. Total range 42 to 210; each subscale 7 to 35. Percentiles are gender-matched.
The CATI is not a diagnostic instrument. Above either cutoff means your responses pattern more similarly to autistic than non-autistic adults in published samples; below does not rule out autism.
Subscale interpretation
Social Interactions
Desire for, and self-appraisal of, social interactions. High scores indicate a preference to avoid social contact and/or finding it stressful.
Communication
Use and understanding of non-verbal communicative behaviours (facial expressions, body language, figures of speech).
Social Camouflage
Use of compensatory strategies (scripts, monitoring, mirroring) to fit in or appear non-autistic.
Cognitive (In)Flexibility
Preference for routines and predictability; difficulty adapting to unexpected changes.
Self-regulatory Behaviours
Use of repetitive physical actions (rocking, fiddling, hair-stroking) to manage stress or maintain focus.
Sensory Sensitivity
Heightened sensitivity to sensory stimuli: light, sound, touch, taste, smell.

The Comprehensive Autistic Trait Inventory (CATI) is a 42-item self-report measure of six dimensions of autistic traits, developed by Chris English and colleagues at the University of Western Australia.
Percentiles and gender-specific cutoffs on this page are computed from the normative tables in English et al. 2025 (Autism); preprint and full norm tables at osf.io/v3kf7. The original CATI development paper (English et al. 2021, Molecular Autism 12(1):37) used a single overall cutoff of 134 with sensitivity 82.7% and specificity 79.0%.
