Intolerance of uncertainty (IU) is a cognitive construct in obsessive-compulsive disorder (OCD); yet no studies exist confirming the factor structure of the most widely used measure of IU, the intolerance of uncertainty scale (IUS), in OCD patients. Moreover, no studies have examined how scores on this measure relate to OCD symptom dimensions. Accordingly, the present study examined a 12-item t...

RESULTS AN and BN groups showed higher IU compared with CW. In AN and BN, Harm Avoidance and Depression scores were p...
