Validation of a Classification System for Obsessive-Compulsive and Related Disorders Based on DSM-5
Abstract: The purpose of this study was to examine whether a broad obsessive-compulsive and related disorders model, which consisted of obsessive-compulsive, hoarding disorder, body dysmorphic, trichotillomania and pathological skin picking, displayed sufficient data fit. On the other hand, we examined whether a reduced obsessive-compulsive and related disorders symptoms model consisting of above mentioned disorders demonstrated superior fit or not. To test the factor structure validity of the classification system of obsessive-compulsive spectrum disorders, we used Confirmatory Factor Analyses (CFA). Result of factor structure analysis revealed and supported an OCSD symptoms dimension that included obsessive-compulsive, hoarding disorder, body dysmorphic, trichotillomania, and pathological skin picking symptoms. Also, results of this study supported the DSM-5 changes.
