Design outcomes

Primary

Measure	Time frame
The study's endpoints (target criteria) are to be recorded as follows: The primary endpoint is to collect usable data sets from over 300 individuals. This data will then be analysed and evaluated against the defined target criteria. Data collection is planned as a one-off event, beginning in July 2025. In addition, a replication study is planned around six months later to validate the results. The specific dates are therefore the initial data collection in July 2025 and the replication study in January 2026. Data will be collected using various validated questionnaires and scoring systems, including the German version of the Perth Alexithymia Questionnaire (PAQ), the Ritvo Autism and Asperger Diagnostic Scale-Revised (RAADS-14), the Comprehensive Autistic Trait Inventory (CATI), the Depression Anxiety Stress Scales (DASS-21), the Eating Disorder Examination – Questionnaire (EDE-Q), the Self-Report Questionnaire of Camouflaging Autistic Traits (CAT-Q) and the Swedish Eating Assessment for Autism Spectrum Disorders (SWEAA-G), as well as the Internal–External Control Conviction–4 (IE-4) scale.	—
