Comparisons between obsessive-compulsive disorder and trichotillomania in terms of autistic traits and repetitive behaviors in adolescents.

Abstract

Our study aims to reveal the relationship between autistic traits and repetitive behaviors in adolescents diagnosed with obsessive-compulsive disorder and trichotillomania and to compare them to healthy controls. A total of 100 adolescents, 33 of whom were diagnosed with obsessive-compulsive disorder, 32 of whom were diagnosed with trichotillomania and 35 healthy controls, aged 11-18 years, who applied to a Child and Adolescent Psychiatry Outpatient Clinic between February 2023 and July 2023, were included in the study. Participants were evaluated with the Autism Spectrum Quotient (AQ)-Adolescent, Repetitive Behavior Scale-Revised (RBS-R), Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS), and Clinical Global Impression Scale-Severity (CGI-S). SPSS 25.0 program was used in the analysis. p < 0.05 was accepted as the significance level. It was found that adolescents diagnosed with obsessive-compulsive disorder and trichotillomania had higher autistic trait levels compared to healthy controls, while there was no significant difference between the obsessive-compulsive disorder and trichotillomania groups. While stereotypic, routine, sameness, and restricted repetitive behaviors were more common in the obsessive-compulsive disorder and trichotillomania groups as opposed to healthy controls, it was found that compulsive behavior was more common in the obsessive-compulsive disorder group, and self-injurious behavior was more common in the trichotillomania group compared to healthy controls. The findings of our study indicate that adolescents diagnosed with trichotillomania, similar to those with obsessive-compulsive disorder, have a higher level of autistic traits and repetitive behaviors. The authors believe it is crucial to focus on the social skill difficulties these adolescents may be experiencing.
