Abstract
Obsessive–compulsive disorder (OCD) in children and adults is a heterogeneous disorder associated with significant psychosocial impairment. Although factor analytic studies have identified symptom dimensions, these analyses do not capture the varied miscellaneous symptoms that fail to load on a specific dimension despite being functionally related. The present study sought to extend the findings of previous research in adults to a sample of youth with OCD ( n=131). Logistic regression analyses were used to examine the predictive value of each of the four symptom factors (contamination symptoms, obsessions and checking, symmetry and ordering, and hoarding) to the miscellaneous OCD symptoms. The vast majority of miscellaneous symptoms (17 of the 18 symptoms) were associated with one or more symptoms factors (i.e., contamination symptoms, obsessions and checking, symmetry, and ordering). Hoarding was not related to any miscellaneous symptom. In addition to improving our understanding about the clinical presentation of pediatric OCD, findings also have important assessment (e.g., understanding which miscellaneous symptoms relate to certain dimensions) and treatment implications (e.g., hierarchy development).
