Predictors of functional impairment in pediatric obsessive-compulsive disorder

The current study examined factors associated with obsessive-compulsive disorder (OCD) related functional impairment among 99 youth with OCD. A trained evaluator administered the Children's Yale-Brown Obsessive-Compulsive Scale, items assessing family accommodation, and a version of the Brown Assessment of Beliefs Scale that was modified for children. Youth completed the Child Obsessive-Compulsive Impact Scale-Child Version, Obsessive-Compulsive Inventory-Child Version, Multidimensional Anxiety Scale for Children, and Children's Depression Inventory-Short Form. The child's parent completed the Child Obsessive-Compulsive Impact Scale-Parent Version. Results indicated that OCD symptom severity, depressive symptoms, and family accommodation were directly related to impairment, while insight was inversely related to functional impairment. Insight, family accommodation, and depressive symptoms predicted parent- and/or child-rated functional impairment above and beyond OCD symptom severity. Among symptom dimensions, contamination/cleaning and aggressive/checking symptoms were the only dimensions significantly associated with impairment. Assessment and treatment implications are discussed; specifically, we highlight how the variables of interest may impact clinical presentation and treatment course. (C) 2009 Elsevier Ltd.
