What this trial studies
This observational study investigates the agreement between self-reported and informant-reported DSM-5 personality disorder traits in adults diagnosed with Autism Spectrum Disorder (ASD). Participants will complete the Structured Clinical Interview for DSM-5 Screening Personality Questionnaire (SCID-5-SPQ) to assess their personality traits. The study aims to enhance the reliability of self-report measures, which are crucial for both research and clinical assessments in this population. By comparing self-reports with those of informants, the study seeks to provide insights into the accuracy of self-perception among adults with ASD.
Why it matters
Potential benefit: If successful, this study could improve the accuracy of personality assessments in adults with autism, leading to better tailored clinical services.
How similar studies have gone: While there is limited research specifically on this topic, studies examining self-report versus informant-report in other populations have shown varying degrees of success, indicating the potential for valuable insights in this area.
