ABSTRACT

ObjectiveTo study the symptom dimensions of obsessive-compulsive disorder(OCD) of Chinese patients.MethodsThis study examined apriori categories used to group types of obsessions and compulsions in the Yale-Brown Obsessive Compulsive Scale symptom checklist,in a group of Chinese patients with OCD ( n=536).A principal-components factor analysis with a varimax rotation was performed.ResultsFive factors( explaining)-hoarding( 16.17％ ),contamination/cleaning ( 13.65％ ),symmetry/ordering( 12.82％ ),aggressive/checking( 10.44％ ),somatic/repeating(8.38％ )-emerged in this analysis,in total accounting for more than 60％ of the variance.ConclusionThe result suggests a multidimensional model of Chinese OCD patients and these five factors may be helpful in identifing the subtype of OCD.
