Elevated Autism Spectrum Disorder Traits in Young Children with OCD

Area of Science:

• Child and Adolescent Psychiatry
• Neurodevelopmental Disorders
• Pediatric Mental Health

Background:

• Autistic spectrum disorder (ASD) traits are common in individuals with psychiatric disorders.
• Prevalence of ASD traits in young children with obsessive-compulsive disorder (OCD) is understudied.
• Understanding this comorbidity is crucial for accurate diagnosis and treatment.

Purpose of the Study:

• To investigate the prevalence of ASD traits in young children (ages 5-8) diagnosed with OCD.
• To determine if elevated ASD traits in this population are associated with OCD severity.
• To compare findings using the Social Communication Questionnaire (SCQ) and the Social Responsiveness Scale (SRS).

Main Methods:

• Recruited 127 children aged 5-8 years from the "Pediatric Obsessive-Compulsive Disorder Treatment Study for Young Children (POTS Jr.)".
• Administered the Social Communication Questionnaire (SCQ) and the Social Responsiveness Scale (SRS) to assess autistic traits.
• Correlated ASD trait scores with OCD severity measures.

Main Results:

• The Social Responsiveness Scale (SRS) indicated elevated autistic traits in children with OCD.
• Elevated SRS scores were significantly associated with greater OCD severity.
• The Social Communication Questionnaire (SCQ) did not show heightened ASD symptoms in this cohort.

Conclusions:

• Young children with OCD may exhibit subtle autistic traits, particularly in social responsiveness, even without a formal ASD diagnosis.
• The findings suggest a potential link between social communication challenges and OCD severity in pediatric populations.
• Further research is warranted to explore the clinical implications and underlying mechanisms of this comorbidity.
