Aim. This study examines the obsessive-compulsive disorder (OCD) with normal and poor insight of illness and it detects the presence of autistic traits. The aim is to establish the relationship between OCD and Autistic Spectrum Disorder (ASD): comorbidity or subtype of OCD? Methods. The sample consists of 48 adolescents (aged 12-18) with a clinical diagnosis of OCD (according DSM-IV-TR). After administering the Children's Yale Brown Obsessive-Compulsive Scale (CY-BOCS) and the Brown Assessement Beliefs Scale (BABS), the sample is divided into two groups according to insight of illness. Autism Diagnostic Observation Schedule (ADOS) and Social Communication Questionnaire (SCQ) were used to assist in the ASD diagnosis; Structured Clinical Interview for DSM-IV Axis 11 Personality Disorders (SCID-I I) was administered to assess personality disorders. Results. 47% of subjects presents poor insight and 27% are included within the diagnostic criteria for autistic spectrum disorder. Poor insight in obsessive-compulsive symptoms is significantly associated with the presence of autistic traits. There is also a significant association between cluster hoarding and poor insight. Discussion. This study suggests the existence of an obsessive autistic atypical subtype, where the compulsive dimension of repetitive behaviours vanishes in an autistic dimension with stereotyped manifestations. Further research should be conducted to better understand this obsessive autistic atypical subtype and to put it in the obsessive-compulsive spectrum in adolescence.
