Scale Overview & Construct
121-item screening questionnaire designed to help distinguish autism-spectrum traits from schizotypal traits in adults, across two dimensions: Autism (71 items) and Schizotypy (50 items). The published protocol also included demographic questions, 3 objective-answer Cognitive Reflection Test items, and 3 multiple-choice social-cognition vignette items; all of those are excluded here since this platform only supports self-report Likert items.

Governance, Boundaries & Ethical Use
Imported from the OpenScales open item-bank project. This specific digital implementation has not been independently clinically validated by PsiQ — scores are for self-reflection, research, and educational purposes only, and are not a diagnosis. The cited source paper is a pre-registration protocol; final validated scoring thresholds may appear in a later publication, so scores here are indicative only, not a validated cutoff-based screen.
