Abstract
BackgroundBoth people with autism spectrum conditions (ASC) and borderline personality disorder (BPD) are significantly challenged in terms of understanding and responding to emotions and in interpersonal functioning.AimsTo compare ASC, BPD, and comorbid patients in terms of autistic traits, empathy, and systemizing.Methods624 ASC, 23 BPD, and 16 comorbid (ASC+BPD) patients, and 2,081 neurotypical controls (NC) filled in the Autism Spectrum Quotient (AQ), the Empathy Quotient (EQ) and the Systemizing Quotient-Revised (SQ-R).ResultsOn the AQ, the ASC group scored higher than the BPD group, who in turn scored higher than the comorbid group, who scored higher than controls. On the EQ, we found the comorbid and ASC groups scored lower than the BPD group, who were not different from controls. Finally, on the SQ-R, we found the ASC and BPD group both scored higher than controls.ConclusionsSimilar to ASC, BPD patients have elevated autistic traits and a strong drive to systemize, suggesting an overlap between BPD and ASC.
Highlights
Autism Spectrum Conditions (ASC) are diagnosed by the presence of social and communication difficulties, alongside unusually strong, narrow interests and/or unusually repetitive and stereotyped behaviour
On the Autism Spectrum Quotient (AQ), the autism spectrum conditions (ASC) group scored higher than the borderline personality disorder (BPD) group, who in turn scored higher than the comorbid group, who scored higher than controls
On the Empathy Quotient (EQ), we found the comorbid and ASC groups scored lower than the BPD group, who were not different from controls
Summary
On the AQ, the ASC group scored higher than the BPD group, who in turn scored higher than the comorbid group, who scored higher than controls. On the EQ, we found the comorbid and ASC groups scored lower than the BPD group, who were not different from controls. On the SQ-R, we found the ASC and BPD group both scored higher than controls
