An observational study in Autism Spectrum Disorder, sponsored by Parnassia Groep. Recruiting at 1 site in Netherlands. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-07-17.
Sponsored by Parnassia Groep · Observational
Rationale: Self-report measures are frequently used for research and clinical assessments of adults with autism spectrum disorder (ASD). However, there has been little research examining agreement between self-report and informant-report in this population. Reliable self-report measures are essential for conducting research with and providing high quality clinical services for adults with autism spectrum disorder.
Objective: This study aims to examine the usefulness of self-report of DSM-5-TR PD traits in adults with ASD compared to informant-reports by administering the self-report screening measure of the Structured Clinical Interview for DSM-5 Screening Personality Questionnaire (SCID-5-SPQ).
1,030 studies on the registry are indexed under Autistic Disorder; 266 are open to participants now.
