Abstract

Controversy surrounds the classification of obsessive-compulsive spectrum disorder (OCSD) symptoms. In this study, we tested whether a broad OCSD symptoms model consisting of obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, pathological skin picking, impulsivity, and anxiety symptoms displayed sufficient data fit. Alternatively, we tested whether a reduced OCSD symptoms model consisting of obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, and pathological skin picking symptoms demonstrated superior fit. The reduced OCSD symptoms model demonstrated good data fit. However, the broader OCSD symptoms model only displayed marginal data fit. In context with other findings, results of this study support an OCSD symptoms dimension that includes obsessive-compulsive, body dysmorphic, health anxiety, trichotillomania, and pathological skin picking symptoms. Implications of these findings are discussed as they relate to proposed changes in the forthcoming edition of the Diagnostic and Statistical Manual.
